SYNOPSIS
A brief little warm up is expected to close out the work week, with temperatures by Friday making a run into the 50s for southern New Hampshire and coastal western Maine. By Friday an area of mostly rain will slide across New England, but some light snow is possible in the mountains. Even though the main area of precipitation moves out rather quickly Saturday morning, some showery weather is likely to continue through the weekend.
Attention then turns to early next week, when a more organized coastal storm is possible.
NEAR TERM /TONIGHT/
Broad, light southwest flow continues across the region through this evening into tonight as high pressure builds over the Atlantic and low pressure crosses to the north. The larger synoptic picture features fast zonal flow aloft with numerous weak, quickly-moving disturbances crossing the eastern CONUS through the next couple of days. One of those disturbances crosses to our south overnight with mixed mid-level cloud decks being the primary marker over New England. Given the ongoing PGF and these clouds, am expecting a relatively mild overnight when compared to prior nights with lows mainly in the 30s...
although the more sheltered valleys are more favored to decouple and cool into the 20s, perhaps the upper-teens in a few spots given low dew points today.
SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/
By daybreak Friday, a cold front will be pushing across the international border, losing forward momentum as its parent low exits east through Maritime Canada. Shortwave ridging builds in behind the departing wave during the morning, which will allow for mostly clear skies south of the mountains and in turn will allow temperatures to warm into the 40s to the lower-50s through the morning into the early afternoon. Further north, clouds and scattered rain showers (wet snow showers across the peaks) will be present with the front stalling near the international border.
By the afternoon, high cirrus clouds will overspead the area from the west with a steady thickening and lowering trend. This comes in response to the next upper level shortwave zipping across the region, which will bring a quick bout of mainly light precipitation across the forecast area Friday evening and overnight as the low rides along the stalled front. Overall model trends have been fairly steady over the last several runs, with primary differences in the north-south location of the track owing to uncertainty in the southward progress of the aforementioned cold front before stalling over northern New England. At this point, there is strong confidence that the wave will bring a band of warm frontal lift across the middle of New England... allowing measurable precipitation to impact most or all of our forecast period.
With deep southwest flow preceding the system... I'm not expecting a lot of wet-bulbing due to steadily increasing dew points through the low and mid-levels. At the surface, sunshine and warming from earlier in the day favor rain as the predominant p-type outside of the mountains. HRRR means and PMMs are well clustered for the QPF forecast, with the axis of maximum precipitation extending along the boundary from southern lower Michigan across upstate New York and through the northern third of our forecast area. Whereas southern areas can expect just 0.1-0.3" or so of total rain, areas further north may approach 0.5" of total liquid equivalent with all or some of this falling as snow in some places.
Snowfall accumulations are expected to be primarily elevation based with light, slushy accumulations of an inch or so on the high end in the valleys. Across the peaks and ridges especially toward the international border and Moosehead Lake region however may pick up closer to 3-5 inches of snow. A quick burst of heavier snow is possible upon onset, and although accumulations may exactly be spectacular this could still lead to reductions in visibility across the north during the evening.
Dry air cuts in behind the quick hitting wave and ends widespread precipitation from west to east late in the evening and through the overnight. It'll remain cloudy however with lows only coming down (or holding steady) into the 30s.
LONG TERM /SATURDAY THROUGH WEDNESDAY/
Overview: The region will be beneath a departing mid level ridge and incoming trough Saturday through the beginning of next week. This will result in numerous weak disturbances moving through the region. Of greater confidence will be on and off snow/rain showers in the mountains, with more spotty showers outside of here. Temperatures will also tend to run warm up to the middle of next week. A larger storm system is possible come Monday.
Details: Exiting low pressure into the Gulf of Maine Saturday morning will drape low level moisture across the region. Full saturation is noted primarily in the low levels, generally 700-800mb and below. This will be enough to keep showers mentioned, primarily across the mountains. Towards the coast and interior, these may be more hit or miss without additional lift or capture of moisture. Would lean on better chances of just seeing a few sprinkles or flurries here.
Mid-level heights sloping from TX through New England will keep a conveyor belt of disturbances tracking into the region. These are generally weak, but combined with the moisture mentioned above, should keep showers and overcast skies in the forecast for a good chunk of the weekend. Reinforcing low pressure will enter this pattern across the Central Plains come Saturday. This will translate into a more distinct area of low pressure in New England come Sunday night and Monday.
Evolution of the surface low and strength of the surface high to the north will play heavily into precip types across the area. Guidance continues with a broad spread of low centers amid ensemble guidance and deterministic runs holding in their camps. Of greater confidence is the high pres locking in cool air NW of the mountains due to strong high pres slowly eroding north. This cooler air could be overcome should parent low pres continue to track up the St Lawrence Valley as suggested by the GFS. Its ensemble however pauses a lot of these running outcomes, transferring energy to an offshore low. This transfer is most represented by the ECMWF and EPS, with only a handful of members taking a surface low north of the VT/Canadian border.
The rest, are widely spread throughout the Gulf of Maine to east of Nova Scotia. This represents a lot of variability that will play on temperature advection throughout the CWA, especially the interior and foothills. To accommodate this spread, have kept a generous spread of rain/snow mentioned during this time period.
As this system heads into the medium term forecast, will keep an eye on guidance that typically performs CAD well, namely the NAM, and sometimes overly so, the HRRR.
This high will look to filter back into the region on the heels of the exiting low. This would keep drier air in the region for midweek with cooler more seasonable conditions following the mild temps over the weekend.
AVIATION /20Z THURSDAY THROUGH TUESDAY/
Short Term...VFR will prevail through Friday morning, before ceilings begin to lower and precipitation moves in Friday afternoon and evening. For the most part this will be MVFR in rain showers, but a quick burst of snow and IFR visibility restrictions is not out of the question at HIE. Low level wind shear around 35-40 kts will impact all terminals overnight, between 00Z and 12Z Saturday.
Long Term...Abundant low level moisture may keep MVFR to IFR ceilings in the region through Saturday and Sunday. Much of these lower heights may trend to the south come Sunday, leaving AUG or RKD more towards MVFR. Scattered flurries or rain showers cannot be ruled out, with these more common towards HIE and the mountains. A larger, more restrictive storm may move through the region come Sunday night and Monday, with a trend to VFR into the middle of next week.
MARINE
Short Term...Southwesterly flow over the waters gusts to 25-30 kts this evening and tonight with a few gusts around gale force possible over the outer waters. Seas meanwhile will come up to around 5-7 feet over the outer waters and into the outer periphery of Penobscot Bay during the time. Seas and winds diminish through Friday, and remain steady through Friday night at around 10-15 kts with a period of light rain.
Long Term...Below SCA conditions are anticipated Sat/Sun as a broad front stalls overhead. A stronger area of low pressure will approach the region Sunday night and Monday, with potential redevelopment over the Gulf of Maine. This would bring the chance for SCA conditions, both winds and waves, for Monday into Tuesday. High pressure will follow into the middle of next week.
This may prolong SCA winds from the NW, with wave slackening to 1 to 3 ft with highest on the outer waters.
