728am EDT Sunday Mar 26 2023
Low pressure enters southern Canada while a secondary low exits through the Gulf of Maine today. Precipitation tapers off today with west winds and milder temperatures through Monday. A weak low pressure system passes south of New England Monday night, and then a cold front passes through late Wednesday. High pressure builds in for the end of the week, with a moderating trend going into next weekend.
Near Term - Until 6pm This Evening
Update... Latest radar imagery continues to show one last large batch of precipitation extending from Portland to Gray and points north in Maine moving east. Will adjust probability of precipitation for these snow and rain showers. Made minor adjustments to temperatures and dew points for the near term portion of the forecast. Otherwise, little in the way of changes to this package, however the Winter Weather Advisories have been reduced to Maine only as much of the steady snowfall will continue to shift east.
Prev Disc... Low pressure will continue to track through southern Canada with a secondary area of low pressure exiting through the Gulf of Maine. An upper level low will exit to the east as well, allowing snow showers to recede to the mountains where an upslope component to the flow will develop this morning. Elsewhere, mainly dry conditions will continue with gusty westerly winds developing over the region.
There will be some melting today in areas that did have accumulating snow overnight. Mainly high temperatures will reach the 30s in the north to the 40s in the south.
Short Term - 6pm This Evening Through 6pm Monday
A westerly flow will continue tonight with weak ridging aloft. Any snow showers activity will be limited to the far northern mountains and remain light. Despite the cold air advection over the region, temperatures will be on the mild side with mid 20s across the north to the lower 30s in the south.
Long Term - Monday Night Through Saturday
Overview: Weak zonal upper level flow will set up over the region for much of the extended forecast with several nuisance variety weather systems crossing through. Temperatures will remain near normal through the extended.
Impacts: No significant weather related impacts are currently expected. A system crossing to our south on Monday night may bring a few scattered rain and snow showers to southern areas. A cold front will then cross Wednesday afternoon or night, likely bringing more widespread showers along with gusty winds in it's wake.
Forecast Details: Surface high pressure will drift offshore on Monday with zonal 500 mb flow overhead. Partly to mostly sunny skies will allow for a warm day with highs into the lower to middle 50s for areas south of the mountains. Soundings via BUFKIT indicate these mainly clear skies will likely allow us to mix down a rather dry airmass above and therefore continued to go below NBM Tds for this portion of the forecast. Cloud cover will then increase from west to east on Monday evening ahead of a weak area of low pressure that will cross to our south on Monday night. Ensemble guidance has trended drier with this system and therefore other than a few rain/snow showers across southern NH, most areas look to remain dry.
Weak shortwave upper level ridging will build over the area on Tuesday and Wednesday, allowing for mainly dry conditions with slightly cooler highs into the 40s to near 50 degrees south of the mountains with overnight lows into the 20s to near 30. A cold front then looks to cross late Wednesday or Wednesday night, bringing a better chance for more widespread showers to the region. Gusty northwesterly winds and cooler temperatures will then filter in behind this front for Thursday, along with upslope snow showers across the mountains. Precipitation chances then may increase again by next weekend as a storm system to our west drags a series of front over the region.
Have opted to drop the Gale Warnings for this package. All areas will be under SCAs (Small Craft Advisories) for today, with headlines lingering over the outer waters tonight.
Winds and seas will largely remain below SCA thresholds until Thursday behind a cold frontal passage.
