Weekly Outlook July 18-24, 2016

The upcoming week can be described fairly easily. We’ll start off hot, cool off just a bit, gradually get hot again, and then get REALLY hot next weekend. oh sure, there might be a few thunderstorms on Monday, again on Friday, and possibly next Sunday, but the key word there is few. As in, don’t count on getting one to cool you off. And certainly don’t count on helping alleviate the drought any time soon.

A cold front will cross the region today. Before it does though, with plenty of sunshine, temperatures will jump into the lower to middle 90s. When you factor in the humidity, the heat index will be in the middle to upper 90s across the region. As a cold front slices through this airmass in the afternoon, it will trigger showers and thunderstorms, some of which could be strong to severe. As is usually the case, the best chance for severe weather will be north and west of Boston. As the line of storms gets closer to the coastline, it will likely start to fall apart. High pressure then builds in for Tuesday, with cooler air behind the front. However, as the high moves offshore, south to southwest winds will allow temperatures to gradually warm up as the week goes on, with highs getting back into the 90s by late in the week. Another front will approach the region on Friday with another chance for showers and thunderstorms. After that, many of the models are indicating the possibility that the weekend, especially Sunday, could be hot. When we say “hot”, we mean “HOT”, as in, there is a chance that the high temperature in some places might be include a 3rd digit and begin with the number 1. Several of the models have been showing a signal for hot weather next weekend, but as always, timing is everything. Another front will be approaching the region, with the possibility of more showers and thunderstorms. Not only will the timing of the front be a big factor in the development of showers and storms, but it will also have an impact on how hot it gets. We should have more clarity on that as the weekend gets closer.

Monday: A sunny start, then clouds move in with showers and thunderstorms developing in the afternoon. Some of the storms could be strong to severe, with strong winds, hail, torrential downpours, and possibly even a tornado. High 88-95.

Monday night: Showers and thunderstorms taper off in the evening, followed by clearing skies. Low 63-70.

Tuesday: Sunshine and a few clouds. High 77-84.

Tuesday night: Mostly clear. Low 54-61.

Wednesday:Mostly sunny. High 77-84.

Thursday: Sunshine and some afternoon clouds. High 83-90.

Friday: Partly sunny, chance for showers and thunderstorms. Humid. High 88-95.

Saturday: A mix of sun and clouds. High 89-96.

Sunday: Partly sunny, chance for showers and thunderstorms. Humid. High 92-99.

Weekly Outlook July 11-17, 2016

Since summer tends to be much shorter around here than in other parts of the country, we tend to cherish our summer weekends. Firing up the grill, heading to the pool/beach, or just some general outdoor activities are common. So when we get a weekend in July like the one we just had, with plenty of cloudcover, showers, and temperatures holding in the 60s, it makes it feel even worse than it really is. The good news is that now that the weekend is over, things will improve! High pressure will build in, with sunshine and warm temperatures returning. In fact, it will get hot and humid later in the week, with temperatures likely soaring past 90 degrees across much of the region.

Maybe the fog wasn’t quite this thick, but it wasn’t a great weekend.

What about next weekend? Well, that might be a bit up in the air. We’re hoping for nice weather, but at this point, we can’t guarantee it. One model says that Saturday might be a washout. However, even the previous run of this model showed a nice day for Saturday, so we’re inclined to lean towards that instead. Remember though, several models showed a week ago that this past weekend was going to be sunny and hot. This is why forecasts beyond 5 days can be very tricky sometimes.

Monday: A mix of sunshine and clouds, slight chance for a popup shower. High 74-81.

Monday night: Becoming mostly clear. Low 56-63.

Tuesday: Partly to mostly sunny. High 81-88.

Tuesday night: Clear to partly cloudy. Low 61-68.

Wednesday: Sunshine and some afternoon clouds. A few showers and thunderstorms may develop. Becoming humid. High 86-93.

Thursday: Partly sunny. Humid. High 85-92.

Friday: A mix of sun and clouds, chance for a few showers and thunderstorms. Hot and humid with a high of 88-95.

Saturday: A mix of sun and clouds. A shower or thunderstorm can’t be ruled out at this point. High 82-89.

Sunday: Partly to mostly sunny. High 81-88.

Happy Fourth of July from Storm HQ!

 

A few days ago, some of the models were starting to indicate that a prolonged period of hot weather was heading out way for the latter half of this week and into the following week. Well, the models have changed their tune, and it doesn’t look like we’re going to have several days in the upper 90s to lower 100s now. Oh there will still be a couple of warm to hot days, but not many.The other thing the past few months have been lacking is rainfall, and it’s starting to become a problem. There is some in the forecast, but not a lot. We really need a lot, though not at once, as that would create other problems. Overall though, if you’re on vacation this week, things will be pretty nice.

We start the week with a fantastic holiday – sunshine and warm temperatures. Perfect for a cookout, heading to the beach/lake/pool, shooting off fireworks, or all of the above. Tuesday looks “iffy” right now. A system will pass south of New England, but how far south is still up in their air. Some showers and thunderstorms are certainly possible, especially south of Boston. The farther north you go, the more likely you’ll stay dry. High pressure returns on Wednesday, then things get “iffy” again. A series of disturbances will move along the jet stream and across New England for the end of the week and the weekend. Timing these storms isn’t easy, and while our forecast will reflect the uncertainty with a chance of showers and thunderstorms each day, for the most part, things will be good, with none of the days being a washout.

Independence Day: Plenty of sunshine, fading behind some late-day high clouds. High 82-89.

Tonight: Becoming mostly cloudy, chance of showers towards morning, mainly south of Boston. Low 59-66.

Tuesday: Mostly cloudy with showers and a few thunderstorms possible, especially south of Boston. High 80-87.

Tuesday night: Clearing skies.Low 61-68.

Wednesday: Partly to mostly sunny.High 88-95.

Thursday: A mix of sun and clouds, chance for afternoon showers and thunderstorms, mainly north and west of Boston. High 85-92.

Friday: Partly sunny, chance for a few showers and thunderstorms. High 78-85, coolest along the coast.

Saturday: Intervals of clouds and sunshine with a chance for showers and thunderstorms. High 77-84..

Sunday: Partly sunny with a chance for showers and thunderstorms. High 80-87.

Weekly Outlook June 27-July 4, 2016

Here we are, approaching the Fourth of July, and we still haven’t had much heat and humidity. Will that change over the next week? Yes and no. We’ll have a little bit more humidity over the next few days as a cold front starts to approach from the west. The front will take its time moving through, so we can expect showers and a few thunderstorms for Tuesday and possibly into Wednesday. Neither day will be a washout, but we really need the rain. The lack of rainfall across New England recently has led to drought conditions expanding across the area.

Once the front finally moves through on Wednesday, high pressure will build in for Thursday with drier weather, but temperatures will warm back up into the 80s. Another front may bring in some showers late Friday, but again, the day shouldn’t be a washout. After that, high pressure builds back in for the holiday weekend, with sunshine and seasonably mild conditions.

What about the heat? Any of that coming? The answer is “maybe”. The latest outlook for next week from the National Weather Service is calling for near to below normal temperatures.

However, the most recent run of the GFS model is painting a different picture, especially for the end of that period. While we rarely put much stock in most computer models beyond 5-7 days at most, we were rather shocked at the picture the GFS is painting for the following weekend. If you take it literally (which is NEVER a good idea), the model is predicting record heat for parts of the region. While we don’t like to forecast out that far, temperatures closer to normal (upper 70s to lower 80s), seem more likely to us than what the GFS is trying to sell.

Monday night: Cloudy with showers developing towards morning, especially north and west of the Boston.Low 61-68.

Tuesday: Mostly cloudy with occasional showers and a few thunderstorms, mainly north and west of Boston once again. High 76-83.

Tuesday night: Cloudy with scattered showers, possibly a few thunderstorms. Low 60-67.

Wednesday: More clouds than sunshine with additional showers expected. High 75-82.

Thursday: Sunshine and some afternoon clouds. High 81-88.

Friday: A mix of sun and clouds, a few late-day showers are possible. High 80-87.

Saturday: Intervals of clouds and sunshine. High 80-87.

Sunday: Partly to mostly sunny. High 78-85.

Independence Day: Sunshine and a few clouds. High 78-85.

Weekly Outlook June 20-26, 2016

We’ve got a bit of an up and down week ahead of us weather-wise, but for the most part things will be pretty good. We start the week with high pressure giving us very warm temperatures on Monday, but humidity levels will be rather comfortable. Humidity jumps up ahead of a cold front for Tuesday. That front will produce some showers and thunderstorms, but at this time it doesn’t look like we’ll have much, if any, severe weather with the front. High pressure returns on Wednesday with drier and cooler conditions. Another low pressure area passes to our south on Thursday, with some rain and cool conditions expected (probably not a beach day). High pressure returns for the weekend.

Down in the Bay of Campeche, Tropical Depression Four has formed. Don’t worry about it too much, it won’t be around for long. It should head westward and make landfall in Mexico Monday afternoon. It may or may not reach tropical storm strength by then (we’re thinking NOT), but if it does, it will be named Danielle.

Weekly Outlook – June 13-19, 2016

Sunshine. Fair-weather cumulus clouds. Gusty winds. Below normal temperatures. Upper-level low pressure. Low humidity. Ridge of high pressure. Above normal temperatures. All of these things are part of the forecast for at least one day this week. See anything missing from that list? Go on, give it another look. We’ll wait. Give up? If you said “rain”, then you’re correct! That’s right, we appear to have a rain-free week coming up across the area.That’s great if you’re on vacation, otherwise, not so much. You see, we’re actually in a drought around here, and it’s slowly been getting worse, because we haven’t received a lot of rain over the past few months. So, we actually need the rain.

Latest update on drought conditions across the Northeast. Some moderate drought is starting to appear across northeastern Massachusetts, southeastern New Hampshire, and extreme southern Maine. Graphic provided by the National Drought Mitigation Center.

The week will start off on the cool side with an upper-level low pressure area slowly moving across southeastern Canada. This will also provide some gusty winds for Monday and possibly Tuesday, but they won’t be as strong as we saw on Sunday. As the low pulls away and high pressure builds in, we’ll see sunshine for the latter half of the week, with temperatures gradually rising. It still doesn’t look like there’s any sustained heat in our future, but a few warm days are possible at times, especially as we head into next week.

Monday: Sunshine and some afternoon clouds, breezy. High 67-74.

Monday night: Mostly clear.Low 49-56.

Tuesday: Partly to mostly sunny. High 71-78.

Tuesday night: Clear skies. Low 52-59.

Wednesday:A mix of sun and clouds. High 74-81.

Thursday: Partly sunny.High 76-83.

Friday:A mix of sun and clouds. Just a slight chance for a pop-up shower in the afternoon. High 69-76.

Saturday: Plenty of sunshine.High 74-81.

Sunday: Mostly sunny.High 79-86.

We must note that there is the possibility that next weekend is not as sunny or mild as our forecast suggests. The ECMWF model paints a starkly different picture.

ecm_mslp_east_8
ECMWF forecast for Sunday morning June 19. Image provided by WeatherBell.

As you can see above, the ECMWF has a Nor’easter develop and slowly move up the coast, giving us windy, cool, and damp conditions from Friday into early next week. The GFS model shows this feature as well, but it has it significantly farther south, and much weaken when it does start to move northward during the first half of next week. For now, we’re leaning towards the GFS solution, but we figured we’d let you know that there is still a chance that next weekend will suck. If that chance grows at all during the week, we’ll let you know.

Weekly Outlook June 6-12

The upcoming week is going to feel like Summer to start and Spring to end. The first half of the week will be unsettled, with an upper-level low pressure area in southern Canada controlling our weather. Although it will be warm, we’ll have a daily chance of showers and thunderstorms through mid-week, with the best chance coming on Tuesday as a cold front crosses the region. By Thursday we’ll start to dry out as high pressure builds in behind the cold front, but with it will come unseasonably cool conditions. Things may turn unsettled again next weekend as another storm system may move through the region.

Tropical Storm Colin should pass well south and east of the region later this week, with minimal impacts on our region. It might increase the surf a bit along south-facing coastlines, so grab your wetsuit and board if that’s your thing. Otherwise, you should probably stay out of the water because A) it’s still pretty chilly and 2) it’s not that safe.

Weekly Outlook: May 30 – June 6

We’ve got a little bit of everything in this week’s forecast. Well, OK, not everything, there’s no snow in the forecast, but just about everything else. We start off with a rather wet Memorial Day, thanks to a cold front and the moisture from “Bonnie”.

Tuesday, we get back into the sunshine and warm temperatures with high pressure building in. Wednesday looks to be dry as well, but a backdoor cold front may bring another cooldown to coastal areas into Thursday. The end of the week looks a bit unsettled and a little cool for early June, with another cold front slowly moving into the region, giving us a chance for more showers and thunderstorms.

Sunday: Intervals of sun and clouds, more showers and thunderstorms possible.High 68-75.

Weekly Outlook – May 23-30

The upcoming week will feature a wide range in temperatures across the region, as is typical of Spring in New England. However, as we approach Memorial Day, the traditional start of Summer, it looks like some summer-like weather will finally settle in. As always though, there is a fly in the ointment – a backdoor cold front.

We’ll start the week with clouds and cool temperatures, thanks to low pressure moving up the East Coast. It will spread the clouds in today, with showers moving in tonight and Tuesday.

High pressure starts to build in on Wednesday with sunshine and warmer temperatures. Thursday is where things start to get tricky. It should be a warm day with showers and thunderstorms likely in the afternoon as a cold front moves through the region. That front stalls out to our south, so Friday will be likely cooler, especially along the coast, thanks to a wind off the still-cool ocean. The big question is, when does the front head back to the north as a warm front? If it’s late Friday, as some models suggest, then temperatures could spike into the 80s in the afternoon across inland areas while the coast stays cool. If it’s late Saturday, then Friday remains cool in most spots, while Saturday could see the temperatures spike in the after noon. Showers and thunderstorms are likely to accompany the front as well. Regardless of when the front comes through, Sunday and Memorial Day look look to be partly to mostly sunny and quite warm, with temperatures well into the 80s, maybe even low 90s in a few spots. A few showers and thunderstorms may pop up each afternoon, but it looks like the bulk of the activity will stay to the north.
