Today will feature the beginning of a late-week warming trend as low pressure begins to stroll across the Great Plains to our west. Look for northwesterly breezes to shift more towards the west as the day goes on and morning sunshine gives way to afternoon clouds. Highs will range from the low 30s up in the mountains to the upper 40s along the coast. No precipitation is expected across the area today, but a round of snow and mixed precip will move in tonight. Impacts will be minimal but you will notice some slick spots on the way out the door tomorrow morning, especially in the north and mountains before warmer air moves in from the south.
Today will feature a nice reminder that spring in New England doesn’t come easy. The cold air that has been pouring into the region aloft over the past few days will finally hit the deck today, keeping temps well below what we’d expect in late March. Highs will range from the mid 10s up north to the upper 20s right along the shoreline. Any breaks of sun you might get along the coast this morning will quickly become obscured as daytime heating clouds pop up. These clouds will drop snow showers and possibly some squalls across the region during the afternoon. The strong late-March sun, even through the clouds, will prevent much accumulation but watch for reduced visibility and some slick spots on the evening commute. NW winds will also be gusty at times, especially in the mountains, pushing wind chills into the single digits. Nothing we can’t handle, but there have been a few 60-70F days between us and the last time it was this chilly so there will be a bit of a shock to the system on the way out the door.
We’re still looking at some unsettled weather today as cold air continues to pour through the region aloft, but not at the surface (yet). Patchy morning sunshine outside the mountains will push temps into the mid to upper 40s along the coastal plain as a strong cold front approaches from the west. With much colder air aloft, there will be enough instability to support another round of afternoon showers. These may drop small hail and graupel in addition to rain. As winds flip around to the northwest, rain showers will flip over to snow showers later in the afternoon/evening, especially up in the mountains. Temps will quickly fall below freezing after dark, leading to patchy black ice.
A rather potent shot of cold, at least for this late in the winter, is on the way for tomorrow when highs won’t eclipse 30 and snow showers will be widespread.
Cold air continues to arrive overhead, but is still lacking in its ability to find the ground. That means we’ll have another day of seasonably mild temps, especially outside the mountains, as well as unsettled weather during the afternoon as daytime heating clouds bubble up. Look for any partial sunshine this morning to become obscured by those clouds this afternoon. Any of these clouds could drop some precipitation by early/mid afternoon which would fall in the form of snow in the mountains and rain possibly mixed with hail/graupel closer to the coast.
High temps will range from the mid 30s up north to the mid 50s in southern NH.
Yesterday’s chilly storm is moving off to the northeast this morning with just a few last rain/snow showers over Maine’s eastern foothills. These should clear out in the next hour or two. Behind the departing system, skies will clear from west to east as cooler air attempts to arrive. The cold airmass will be stymied at the surface by downsloping and the strong late-March sun. As a result, temps will be milder today, ranging from the low 40s up in the north and east to the upper 50s in southern NH.
Aloft, the incoming Canadian airmass will find no resistance which means we’ll have some instability develop (cold air likes to sink, warm air likes to rise, put cold on top of warm and you get instability). So any midday sunshine will become obscured by daytime heating-driven clouds by mid afternoon. Some of these clouds will produce showers especially in the mountains. Don’t be shocked if the showers come with a bit of small hail given the instability and cold air aloft.
Showers will die down around sunset as instability wanes.
Today will feature cooler temps and unsettled weather as a weak storm moves in from the southwest. Cold air dammed up against the mountains has been supporting light mixed precip across much of the area west of I-95 this morning. As the sun comes up and winds shift a bit more to the south, expect the mix/rain line to advance inland, though of course slower than most guidance expects. The interior foothills and mountains seem likely to cling to near or below freezing temps for much of the day, leading to some modest sleet/ice accumulation. For the most part this looks like just a slick travel threat though, especially on untreated roads. For the rest of us, any morning sleet/ice will change over to a cold rain as temps rise into the mid/upper 30s. Rain will let up briefly this evening before resuming overnight and changing back to snow in the mountains as low pressure redevelops offshore. Accumulations are expected to be modest (1-3″ mostly) and confined to the higher terrain.
Mild and quiet weather continues today as high pressure slides overhead. Morning sunshine will gradually give way to some afternoon clouds moving in from the west. Winds will be light out of the northeast this morning, shifting east/southeast during the afternoon. As a result, the warmest temps (low 50s) are expected in interior NH while most of southern Maine tops out in the upper 40s. The mountains and northern foothills will be chilliest, ranging from the upper 30s to low 40s.
Northwest breezes behind yesterday’s departing storm system will control our weather today. As a result, we’ll be dusting off the usual upslope/downslope playbook with clouds and snow showers up in the mountains where highs will be limited to the low/mid 30s. Meanwhile along the coast, downsloping will favor widespread sunshine and milder temps ranging from the low 40s near Augusta to the mid 50s in southern NH. NW breezes will be gusty, especially over NH, but shouldn’t rise above nuisance levels.
Today will feel a lot more like May than March as downsloping and ample sunshine push temps well above where they should be this time of year. Highs will range from the mid 50s up north and right along the shoreline to the mid 70s across much of southern NH and adjacent interior parts of York County. While most of the day will be sunny across most of the area, some low clouds and fog are noted on satellite imagery this morning and may take a few minutes to burn off especially along the coast. Some high clouds may also filter in from the west around sunset.
Today will feature warm temperatures, especially away from the coast and somewhat unsettled weather, especially closer to the coast as a weak coastal storm approaches the Gulf of Maine. Low clouds dominate the landscape this morning north of about Route 2 and east of about the Maine Turnpike. The mountain clouds should clear out in the coming hours while low clouds and fog hold tighter along the shoreline. Some mid/high clouds will then arrive from the southwest this afternoon ahead of this weak coastal system. It’s not expected to bring us much in the way of impacts but some showers are possible in southern NH and along the Maine coast. The timing for these showers would be mid/late afternoon.
High temps will range from the low 40s along the Midcoast to the low 50s in the mountains and mid/upper 60s across central/southern NH, the CT Valley, and interior parts of SW Maine.
