SYNOPSIS
Rain continues today, changing to snow in the mountains, before ending this evening. Winds will be gusting to 30 mph Friday night and Saturday behind the departing low pressure. Light snow showers possible early Sunday morning, mainly over New Hampshire, before our pattern becomes drier and warmer into Monday. The pattern becomes unsettled again Tuesday, with a chance for a significant system midweek.
NEAR TERM /UNTIL 6 PM THIS EVENING/
Update...Cold/drier air moving in the northwest is undercutting the rainfall rates, so have trimmed the flood watch to all but the midcoast region. Rain will continue along with snowmelt supporting small stream rises and isolated flooding through later today.
Previous discussion...Rain shield continues to slide parallel to the coast this morning...while low pressure continues to deepen south of New England. The back edge of rain is beginning to pull away from the NJ coast now...and that trend will continue from southwest thru the northeast parts of the forecast area thru this afternoon. Rainfall rates remain manageable...but rivers are beginning to rise so I have not changed the flood watches. Rain should generally be confined to the Midcoast by midday and should allow for some clearing of counties from the watch area by then.
Also helping to wind down the rain threat are northwest winds increasing and bringing in some drier air. Winds are already picking up and will only increase thru morning. By midday gusts of 30 to 35 mph are possible.
SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/
Winds will remain gusty tonight thru Sat. Strongest gusts are expected to be immediately in the lee of the mtns...where downslope may gust above 35 mph even with the loss of daytime heating
Some upslope snow showers are possible
but the drier air mass will limit the coverage. Little change is expected Sat. Slightly warmer temps but still gusty.
LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/
Overview: A weak wave passes mostly south of the area early Sunday morning before a ridge builds in for the remainder of the day and Monday. Unsettled weather returns Tuesday with the potential for a significant system midweek.
Impacts: * Confidence is increasing in a significant system affecting the region midweek, however confidence on precipitation type and resulting impacts remain low.
Details: Breezy winds begin to relax Saturday night, but increasing clouds ahead of a weak system should keep most areas from decoupling. Weak cold air advection will still get low temperatures into the 20s across the area, save for southeastern New Hampshire where they can hold on to low 30s. The aforementioned weak system looks to clip central and southern New Hampshire early Sunday morning with some light snow showers.
Southern zones should see little to no accumulations as surface temperatures rise above freezing. Central zones could see some light accumulations but again temperatures will be just below freezing and rising so it will hardly be impactful. Clearing skies should get most of the area into the 40s, or very close, with southern New Hampshire and southwestern Maine standing a good chance of low 50s. Stronger cold air advection will get low temperatures below freezing across the area Sunday night, with the range of 20s making it just short of the immediate coast.
High pressure directly overhead Monday will allow high temperatures to warm into the upper 40s and low 50s south of the mountains with low 40s to the north. Increasing clouds ahead of our next system will keep low temperatures in the mid 20s and 30s. Global models seem to agree that the ridge holds for the better part of Tuesday, but precipitation in some form moves in during the night. Global model ensemble means suggest that 850 mb and surface temperatures remain just on either side of freezing so things will probably look like a rain snow mix outside of the mountains to start. The bulk of the system occurs on Wedensday and might last into Thursday. Preliminary thoughts are that this ends up a mostly rain event south of the mountains with better chances of accumulating snow to the north.
We will continue to monitor the Tuesday night through Thursday window as some details have become clearer, but many aspects of this system remain low confidence.
AVIATION /12Z FRIDAY THROUGH TUESDAY/
Short Term...Despite the rain conditions are mostly VFR and patchy MVFR at this time. I anticipate that will continue thru the morning hours...and then primarily remain VFR into the afternoon
Northwest winds will increase towards daybreak
and surface gusts up to 30 kt are possible this afternoon. Winds will diminish slightly overnight...but are expected to remain gusting around 25 kt thru Sat.
Long Term...Some MVFR ceilings possible with a quick weak system early Sunday morning, otherwise VFR prevails through at least Monday night. Ceilings lower on Tuesday with the potential for some flight restrictions by Tuesday night ahead of what could be our next significant system.
MARINE
Short Term...Northwest winds will steadily increase this morning as low pressure moves thru the Gulf of ME. Gale force gusts are forecast for all waters except Casco Bay. Gusty winds will continue thru Sat.
Long Term...High pressure settles over the waters Sunday into Tuesday keeping conditions below those hazardous to small craft.
HYDROLOGY
Rain rates continue to be on the light side this morning...especially as northwest winds bring in drier air to undercut the precip. The primary impact continues to be small stream and river rises, and flooding along low water crossing and urban areas due to rain and snowmelt. Additional rainfall around 0.5" is possible near the coast and into the lower Kennebec River Valley. Moderate river flooding is not expected at the time of this issuance, with probabilities less than 10%.
Note: Many climate sites are in the top 5 wettest on record, with this late month event expected to approach all time records for Augusta and Portland. Portland's record 11.24" in 2010, Augusta's is 9.71" in 1953.
