A Bit Cloudier Today

Hello everyone!

Today will feature the return of cloudier weather as a storm system slowly drifts towards our region from the west. Currently, satellite imagery shows just a few mid/high clouds streaming through northern New England, but a thicker cloud deck lurks back in Ontario. After a few mostly sunny hours this morning, expect that thicker cloud deck to arrive this afternoon. Before it does, we should be able to enjoy a pretty nice morning except for southwestern NH which seems to be stuck under a thicker low-level cloud deck at the moment.

Before the thicker clouds arrive, expect mostly sunny skies to support warm temps ranging from 60 in the mountains and western NH where clouds arrive first to around 70 along the coastal plain of Maine. The Maine coast will, as usual, cool off later this afternoon as a sea breeze develops and moves inland.

While this next system will bring plenty of clouds to the region, it doesn’t look like its precipitation will be able to move this far north as dry Canadian air rushes south in the lower levels of the atmosphere. That said, a brief sprinkle can’t be ruled out over western NH this evening or tonight.

Lovely Spring Weather Today

Hello everyone!

Today will feature lovely spring weather as dry air filters in from Canada behind yesterday’s cold front. The NW breezes bringing that new airmass into the region will support some upslope clouds up in the mountains while downsloping keeps the coastline mostly clear. The exception may be along the Midcoast east of Brunswick which is farther from the relevant mountains, experiencing more NNW winds than NW winds, and is closer to the low pressure system over New Brunswick and its associated moisture. As a result, expect a few more clouds in this area especially this morning.

For the rest of the coastal plain, clear skies and downsloping winds will push temps into the low 70s this afternoon. The mountains and Midcoast will both remain cooler with highs around 55-60. A sea breeze will cool the immediate shorelines later this afternoon, though I don’t expect it to make much progress inland in the face of larger-scale northwesterly flow.

Enjoy the lovely weather!

Showers and Storms Return Today

Hello everyone!

Today will feature generally unsettled weather as a weak storm system slides through the southern part of the region. Expect a day of mostly cloudy skies as a result of this system’s passage, though a few sunny breaks are possible in southern NH this afternoon.

The main story today will be the arrival of showers and thunderstorms associated with the aforementioned storm system. Radar imagery suggests that showers are already in progress across northern parts of the area this morning. Expect these showers to continue on and off through much of the morning before becoming more sparse around midday.

The main round of showers and storms will arrive in western parts of the area around 4-5 PM. Across northern parts of the region, expect rain to fall mostly as steady showers with the low possibility of an embedded rumble or two. Southern parts of the area will have a better chance to see rain falling as convective cells. Most of southern Maine and Central NH will remain too cool for robust severe weather which will be focused in southern NH near the MA border.

In this region, a series of discrete or semi-discrete thunderstorm cells is expected to develop around 5-6 PM. These cells could produce damaging winds, large hail, and even a brief tornado or two. This threat diminishes greatly north of Concord, though a stray damaging wind gust can’t be ruled out as far north as Plymouth.

Showers and storms will slowly roll east through Maine around sunset with heavy rain and the possibility for some small hail. A cool wind off the water should keep the severe threat quite minimal, especially east of Portland. Either way, it should be a nice evening to fall asleep to the sound of a steady rain and the relaxing rumbles of distant thunder.

High temps today will feature substantial regional variation given the position of the storm’s warm front overhead. Expect highs just shy of 50 in the mountains and near Penobscot Bay while most of Maine’s coastal plain ranges from 55 near Waterville to 65 in interior York County. Farther west in NH, highs will soar as high as 75-80 in southern parts of the state while central areas top out around 70 and the mountains remain locked near 55.

A Brief Glimpse of Warm Weather Today

Hello everyone!

Today will feature a brief glimpse of warm (seasonally average) weather as high pressure slides offshore and winds turn towards the west-southwest. Expect sunny skies across the area except for a few cirrus straying into the region later this afternoon/evening. No precipitation is expected. High temps today will range from 55 in the mountains to 65 along much of the coastal plain to 70 in far southern NH. That’ll feel pretty great after weeks of below-normal temperatures!

Enjoy the warm and sunny weather while it lasts! Tomorrow looks like a day of low 50s and steady rain as low pressure tracks from Buffalo NY to Portsmouth NH which leaves us on the cool and unpleasant side of the system.

Another Cool but Generally Nice Day Today

Hello everyone!

Today’s weather will look a lot like yesterday’s as northwesterly breezes continue on the western periphery of our last storm system. Winds won’t be quite as gusty as yesterday, though some spots will remain annoyingly breezy especially closer to the coast. Thankfully, aside from daytime cumulus clouds this afternoon, we should see sunny skies across the region. Despite that, temps will remain cool today, ranging from 45 in the north to around 60 along the coast. Pretty remarkable for a clear day with as much solar energy as July 30th!

Enjoy the nice weather today (and tomorrow) as we’ll have more showers and possibly a thunderstorm or two arrive on Friday.

Nicer But Still Cool Today

Hello everyone!

Today will feature nicer weather after yesterday afternoon’s showers and thunderstorms. Expect mostly sunny skies (especially outside the mountains) and dry conditions. The one exception will be over central/southern New Hampshire where some clouds and showers will arrive later this afternoon/evening ahead of a weak secondary cold front. While the sun is now shining at the same intensity as late July, our Polar airmass won’t be bothered to warm past 40 in the north and 60 along the coastal plain this afternoon. Fear not for the joys of late spring weather, a (much) warmer pattern is on the way next week!

Showers and Thunderstorms Develop Today

Hello everyone!

Today will feature (slightly) warmer temperatures and mostly sunny skies, at least for the first part of the day. By noon, clouds will be on the increase ahead of our next storm system which will be moving through Albany New York. The warm temperatures developing as a result of morning sunshine along with increased moisture flowing into the region on southerly breezes will support the development of convective showers and storms this afternoon. Expect showers and storms to first pop up in southwestern NH around noon before moving northeast. Many of these cells will produce gusty winds capable of knocking down some trees and power lines, so be aware of the potential for scattered outages this afternoon, especially over southwestern Maine and southern NH where instability, and thus storms, will be most robust.

Convective showers and storms will gradually shift towards steadier rain this evening as the low arrives in the Maine foothills. For those to the north of the low’s track, expect rain to change over to snow tonight with accumulations of 1-3″ possible especially above 2,000 feet north of route 2.

All precipitation will wrap up before sunrise tomorrow. High temps today will range from 50 in the mountains and along the peninsulas of the Midcoast to 60 in interior parts of the coastal plain.
