Yup, the hype train has left the station again and is rolling down the track. You may have heard that there’s a storm coming later this week. We’ll set the record straight between hype and reality, fact and fiction, in this outlook.

The first half of the week, also known as the last 3 days of February (and the last 3 days of meteorological winter) will actually be quite pleasant. High pressure will be in control with sunshine and mild temperatures. It’s not the early taste of spring that we had a week ago, but we doubt there will be many complaints. After that, things start to get complicated.

A “blocking” pattern will set up across the Eastern US. Normally, the jet stream flows west to east, steering storms across the country. When there’s a dip in the jet stream (a trough), we tend to have colder than normal temperatures, along with stormier conditions. We’ll have one of those troughs move into the East later this week, and it will eventually break off from the jet stream (called a “cut-off low”). At the same time, a large upper-level high pressure area will set up shop over Greenland. This will block the eastward progression of storms, meaning that the storm we’re expecting later this week won’t be in a hurry to leave. However, it could also be a good thing. How? If the ridge of high pressure continues to build in, it could deflect that storm farther to the south. Good for us, but bad for places like New York City, Philadelphia, or even Washington.

The models still haven’t come to a consensus on what will happen for the end of the week. There are several things that we need to figure out before we can come up with a forecast that we’ll have any confidence in. What are those factors? Where will the low pressure area track? How strong will it be? How much cold air will be in place before the storm arrives and when it’s impacting the region? How strong will that high pressure area to the north be?  These details will likely take a few more days to be resolved. So, if you hear others, especially in the media, talking about the “3-day storm” or the “snowstorm” that will impact us later this week, take it with a giant grain of salt. Nobody, including us, can say with any degree of confidence, what will happen. We could have heavy rain, heavy snow, strong winds, or all of the above. The only thing we can be reasonably confident about is the fact that some coastal flooding seems likely. The highest tides of the month are expected at the end of the week, and with a storm of some sort off the East Coast, that will likely lead to some coastal flooding across parts of the area. Things should start to improve over the weekend, but even that will depend on the progression of the storm.

70 degrees. In July, that’s a chilly high temperature. In February, it’s a record breaker. We’re going to be challenging and possibly breaking some records this week. Don’t get too used to it though, as our early taste of Spring will be short-lived.

The week starts out with a warm front moving towards the region, spreading in some clouds, and eventually showers on Monday. The front moves through Monday night, then a Bermuda High sets up shop for a couple of days, with unseasonably mild conditions expected for Tuesday and especially Wednesday. How mild? Most locations should reach the upper 50s to middle 60s on Tuesday. On Wednesday, most places should get into the 60s, with some lower 70s possible, especially north and west of Boston. Of course, there is an exception. Along the South Coast, the southwest winds that will bring warmer air in for the rest of us will be blowing in off of water that is still in the 30s. So, these locations will likely stay in the upper 40s and 50s both days. Still nice, but it’s not 60s and 70s.

A cold front moves through Wednesday night, bringing a few showers with it, but also bringing an end to the mild weather. Showers may linger along the south coast into early Thursday before the front pushes offshore, then high pressure builds in from the north with much cooler conditions for Thursday and Friday. Of course, “much cooler” is relative, as these temperatures will still be near to a little above normal for late February. Another storm system then moves in from the west, with some precipitation likely late Friday into Saturday. It should fall mostly as rain, but a period of snow or freezing rain is possible, especially across the Merrimack Valley and southern New Hampshire Friday night into Saturday. We’ll keep an eye on this situation as the week goes on. Another system quickly follows with more rain or snow on Sunday.

Monday: Becoming mostly cloudy and breezy with showers possible late in the day. High 42-49.

Monday night: Showers likely in the evening, otherwise mostly cloudy and breezy. Low 39-46 in the evening, then temperatures rise overnight.

Tuesday: Becoming partly sunny, breezy, and milder. High 57-64, except 49-56 along the South Coast and across Cape Cod.

Tuesday night: Partly to mostly cloudy. Low 46-53.

Wednesday: Partly sunny, breezy, and warm. Showers possible at night. High 65-72, except 49-64 along the South Coast and across Cape Cod.

Thursday: Clouds gradually giving way to some sunshine late in the day, turning much cooler. High 41-48.

Friday: A sunny start, then clouds return. Showers likely at night, possibly starting as some snow or freezing rain in the Merrimack Valley and Southern New Hampshire. High 37-44.

Saturday: Mostly cloudy and turning milder with a chance of showers, possibly some wintry mix early in the day across southern New Hampshire. High 47-54.

Sunday: Cloudy and breezy with a chance of rain or snow. High 36-43.

 

Arctic Outbreaks. Blizzards. Sub-zero wind chills. These things are common around here in the month of February. None of them will be in the forecast this week. In fact, this week will be rather quiet and, believe it or not, mild (for the most part).

The week starts off with a cold front pushing offshore and high pressure building into the Northeast. Any lingering showers will end in the morning, but skies will only gradually clear out. Monday night and Tuesday will be clear and chilly as the high settles in. As the high moves offshore, milder conditions are expected on Wednesday, but clouds will also start to move in as a cold front starts to slowly approach from the west. Thursday will be a cloudy and mild day, with a few showers possible. The front finally pushes through on Friday with some rain and cooler conditions expected. High pressure returns for the weekend with dry and cooler conditions once again.

Monday: Some lingering showers near the South Coast early in the day, otherwise cloudy in the morning, with clearing in the afternoon. High 40-47, except for southeastern Massachusetts and Cape Cod where temperatures will start the day 48-55 then drop.

Monday night: Becoming mostly clear. Low 16-23.

Tuesday: Plenty of sunshine, clouds start to move back in late in the day. High 29-36.

Tuesday night: Partly to mostly cloudy. Low 21-28.

Wednesday: Early clouds, then becoming partly to mostly sunny and milder. High 41-48.

Thursday: Chance for some showers early, otherwise partly to mostly cloudy and mild. High 52-59.

Friday: Some morning showers, then gradual clearing, breezy, and turning cooler. High 46-53 early, then temperatures drop in the afternoon.

Saturday: Sunshine and some afternoon clouds. High 29-36.

Sunday: Mostly sunny. High 40-47.

While it won’t be in the 80s around here this week like it will in Fort Myers, pitchers and catchers report tomorrow. Spring training has arrived, which means we’re that much closer to the end of winter. That doesn’t mean we’re done with snow, but we’re getting there. Don’t forget about the Bruins and Celtics too, and, we’re also less than 3 weeks away from the start of the season for the Revolution.

If you are looking for other signs of Spring, take the following with a grain of salt, but both the GFS and ECMWF models are showing next Tuesday to be a mild day ahead of a cold front. We’re not ready to jump on board with that forecast yet, since it’s still 8 days, but it certainly looks nice. How nice? We’ll let the GFS map do the talking:

 

Sure, that wasn’t the outcome that most of us wanted, but cheer up – there’s snow on the way! Wait, that doesn’t make you feel better? Well, before you know it, Spring will be here. After all, today is Truck Day, and pitchers and catchers report to Fort Myers a week from tomorrow. Does that make you feel better?

The week will actually start off with a couple of dry but chilly days. The system that brought us some rain Sunday night will pull away, and high pressure builds in for Monday with sunshine and cold temperatures. Tuesday will be another chilly day, but the sunshine will be replaced by clouds as low pressure approaches from the southwest. Since the pressure over us today and Tuesday will be moving into Atlantic Canada, it won’t be in an ideal spot to keep the cold air locked into place on Wednesday, meaning that we’ll be dealing with a rain/snow line. Snow will spread across the area during the day on Wednesday, but the question is – how far inland does the rain/snow line penetrate? There’s plenty of disagreement between the models, so we’ll likely have a special blog post about this later on Tuesday, as the details should be more clear by then (we hope). Right now, we’re thinking that the rain/snow line gets to at least I-95, possibly all the way to I-495. Where it stays all snow, we’re talking plowable snow, likely in excess of 6 inches. The best chance for that will be in southern New Hampshire. Elsewhere, some accumulation is expected, with the amounts dependent on how quickly a change to rain occurs, if it occurs at all.

Everything changes back to snow before ending Thursday morning, then high pressure builds back in later on Thursday. However, a quick-moving system spreads clouds back in on Friday, with a little bit of light snow Friday night into Saturday morning. Another system quickly follows for Sunday. Right now, this one looks to be warmer, with mostly rain across the region, however, it’s a week away, and a lot can change between now and then. We wouldn’t be surprised at all if the models trend colder, and that system ends up as more of a snow threat than it currently looks like. We’ll worry about that one later in the week.

Monday: A cloudy start, then becoming partly to mostly sunny and breezy. High 33-40 in the morning, then temperatures hold steady or drop a bit in the afternoon.

Monday night: Clear skies in the evening, then clouds start to roll back in after midnight. Low 15-22.

Tuesday: More clouds than sunshine. High 32-39.

Tuesday night: Partly to mostly cloudy. Low 18-25.

Wednesday: Cloudy with snow developing, changing to rain at least as far inland as I-95. Becoming windy across Cape Cod and southeastern Massachusetts. High 31-38, except for southeastern Massachusetts, Cape Cod, and southern Rhode Island, where temperatures could jump into the 40s towards evening.

Thursday: Any lingering snow or rain ending early, then gradual clearing is expected. High 28-35.

Friday: A sunny start, then clouds move back in. Some light snow is possible at night. High 25-32.

Saturday: Mostly cloudy, some snow showers possible in the morning. High 35-42.

Sunday: Cloudy with a chance of rain or snow, becoming windy across Cape Cod and southeastern Massachusetts. High 38-45, possibly warmer across southeastern Massachusetts, Cape Cod, and southern Rhode Island.
