Weekly Outlook: November 28-December 4, 2016

Here we are, in the final days of November and the beginning of December, ad we’re staring at not one but two storms this week that could bring us heavy precipitation. Of course, that precipitation will be nearly all rain, but we definitely need it, as we’re still in the midst of a drought.

To say that rainfall has been below normal around here for quite some time would be a big understatement. Image provided by the Northeast Regional Climate Center.

The week starts off on a sunny but chilly note thanks to high pressure. You’d better enjoy that sunshine though, because once it disappears behind afternoon clouds, you won’t see it again until Thursday. The first storm system moves through on Tuesday, giving us a good dose of rainfall. Things could be tricky to start though. The rain may arrive before daybreak on Tuesday. With cool weather still in place, temperatures may be close to freezing across central and southern New Hampshire when the rain arrives. This could result in a little freezing rain in some areas, so you may want to be careful heading out the door early Tuesday morning. Temperatures should be above freezing across the region by late morning, ending any potential icing threat. South of Boston, it could be a much different story. Gusty southerly winds could send temperatures well into the 50s on Tuesday. The rain tapers off and ends Tuesday evening, but the next storm will be quickly approaching from the west. This storm will likely head up the St. Lawrence Valley, keeping the entire region mild, but with another round of heavy rain late Wednesday into Thursday morning. Colder air settles in behind that storm, and with an upper-level low pressure area moving through, we could see a few rain or snow showers on Friday. High pressure then builds in for the weekend with dry and cool conditions.

The GFS model is forecasting 1.5-3″ of rain across the region through late Thursday. We need even more to break the drought. Image provided by Pivotal Weather.

Monday: Plenty of sunshine, dimmed by afternoon cloudiness. High 39-46.

Monday night: Becoming cloudy with rain developing towards daybreak, possibly starting as some freezing rain in central and southern New Hampshire. Low 28-35.

Tuesday: Rain likely, possibly heavy at times. Becoming breezy along the south coast. High 45-52 north of Route 2, 52-59 south of Route 2.

Tuesday night: Mostly cloudy with rain tapering off and ending in the evening. Low 39-46.

Wednesday: Cloudy and becoming breezy with rain redeveloping by midday. High 48-55.

Thursday: Any lingering showers ending in the morning, otherwise becoming partly sunny and breezy. High 48-55, except 55-60 south and east of I-95.

Friday: A mix of sun and clouds, slight chance for a rain or snow shower. High 43-50.

Saturday: Partly sunny. High 39-46.

Sunday: Intervals of sun and clouds. High 37-44.

We do need to keep an eye on the start of the following week. Most of the models are indicating that a storm system may impact the region Monday into Tuesday. However, there is very little agreement among the models on how strong the storm might be, how heavy the precipitation might be, and what type of precipitation may fall. So, we’re not going to go into any more details at this time. We’re just giving you the heads up to keep an eye on future forecasts.
