The area of high pressure that has brought us cool and quiet conditions for the past few days has now slid offshore, which means broad southwesterly flow will develop over the area. That southwesterly flow will bring milder weather and increased cloud cover to the region today. Expect high temps ranging from around 30 in the north to around 45 in the south. While overcast skies will develop by this afternoon, any light precipitation associated with the offshore storm will arrive tomorrow morning. Little to no snow accumulation is expected.
Today will feature continued quiet weather as high pressure crests over the region. Expect mostly sunny skies and temps right around normal across the entire area as that high drifts overhead. Temps this afternoon will range from around 25 in the north to around 35 in southern NH. Some high clouds will likely work their way into the region later this afternoon, but generally speaking clear skies will be the rule today.
After a day of relatively moist NW flow yesterday, we’ll get to enjoy some relatively dry NW flow today. As a result, while mountain upslope snows drifted into coastal regions yesterday, coastal downslope sunshine will drift into the mountains today (except for the highest peaks). While the sun will be out trying to warm things up, yesterday’s seasonably cool airmass will be sticking around for at least a few more days. High temps are expected to be right around ‘normal’ for this time of year, ranging from 20 in the north to 35 in the south.
If you’ve heard rumors about a snowstorm this weekend and are curious about my thoughts, I outlined them in detail on the weather.us blog last night. The bottom line is that while a storm is still possible, this pattern will make it hard to get a big one.
Today will feature slightly cooler temps and continued generally quiet weather as low pressure continues to meander around the Canadian Maritimes. NW flow behind that system will continue to be the primary influence on our weather today. Normally, with NW flow we see clouds and upslope precip in the mountains while sunshine rules the coastal plain. However, a weak disturbance embedded within that NW flow will help extend clouds and the chance for snow showers all the way to the coast as it passes through this morning. No impacts of significance are expected, but don’t be shocked if you find a flake or two on your way out the door. Later this afternoon, that disturbance will depart the region and some breaks of sun are expected to develop along the coast.
While there’s no true cold air in sight this side of Hudson Bay, some less-warm air has been filtering into our area in response to those NW breezes. As a result, expect slightly cooler temps today with highs ranging from 25 in the north to around 40 in SE NH.
The storm that brought heavy rain to the region back on Saturday night is still lingering over New Brunswick this morning. An upper level disturbance rotating around the base of the trough responsible for this storm will pass over the region today. This means we’ll end up with cloudier skies and the chance for a few rain/snow showers. Of course, the best chance for precipitation will be found in the mountains though a few drops or flakes are possible farther southeast this morning.
Drier conditions return for the afternoon as SW winds turn around to the NW. As downsloping starts to work its magic, a few breaks of sun are possible along the coastal plain before sunset. With southwesterly winds and no cold air in sight this side of Hudson Bay, we’ll be dealing with another day of above normal temps across the region. Look for highs around 35 in the north and 45 in SE NH.
Our fast-moving storm raced through the region last night and is already well on its way out of the region this morning. While the storm had gusty winds on its front side, there’s no strong cold air advection to be found on the system’s back side. We’ll be left with light WSW winds and relatively mild temps aloft today, which means another day of relatively mild weather is expected. High temps will range from 32 in the mountains to 45 along the coastal plain. Mostly cloudy skies are expected region-wide this morning before light downsloping brings some sunny breaks to the coastline this afternoon. No additional precipitation is expected outside of a few mountain upslope flurries.
Most of today will feature continued quiet weather as high pressure continues drifting off into the Atlantic. Clouds have already overspread the area ahead of our next storm system which is scheduled to arrive this evening. Some drizzle/fog is possible this afternoon, especially in the foothills and mountains, but otherwise any outdoor activities planned for today should be mostly dry.
Here’s a look at observed temperatures as of 6 AM. The coastline is already above freezing while the foothills are within a degree or two of the 32F mark and the mountains are safely in the 20’s. Southeasterly winds will push temps slowly but steadily upward today across the entire area. By this evening, the coastline will be well into the mid 40’s, the foothills will be a little shy of 40F, and the mountains will be right around freezing.
As a result, when precipitation arrives, most of the area will see plain old rain. The exception will be the mountains where a mix of wet snow, freezing rain, and sleet is likely. This is a fast-moving storm so even the spots that end up all or mostly snow (best shot of that is near Sugarloaf) will only pick up a few inches of accumulation. Otherwise, the biggest impact will be some slick backroads.
Closer to the coast, we’ll have different issues to contend with.
Southeasterly winds will ramp up after sunset as the storm’s cold front gets closer. Gusts in the 40-45 mph range are likely along the coastline while inland areas gust in the 25-30 mph range. While this isn’t expected to be a major southeasterly wind event, the threshold for power outage issues is lower with this wind direction, so don’t be surprised if the lights end up out for a few hours especially along the Midcoast.
The other possible issue along the coastal plain will be very heavy rain as the front slices through an anomalously moist airmass. Around 1-2″ of rain is expected to fall in just a couple hours (note the hourly precip rates on the map above) and some small stream/poor drainage flooding is expected as a result. Because the storm is swinging through just after midnight, most of you probably won’t even notice this, but if you head out early on Sunday morning, make sure to keep your eyes out for residual high water spots.
