Area Forecast Discussion National Weather Service Gray ME 340 PM EDT Fri Apr 12 2024

SYNOPSIS
More showers are expected into this evening as a cold front pushes through the area, and although a brief downpour is possible, overall additional rainfall amounts will be limited.
Showers will linger into Friday, ahead of another front. Drier and warmer conditions return for Sunday. High pressure gradually builds in early next week with partly to mostly sunny skies and a warming trend. Cooler conditions with mainly rain expected late next week as low pressure develops to our south.

NEAR TERM /TONIGHT/
Impacts: *Convective showers associated with a cold front may aggravate ongoing snowmelt flooding in the White Mountains early this evening, but are not expected to significantly add to totals.

Widespread rain has moved out of our forecast area, but scattered showers continue in it is wake as the area remains under broad cyclonic flow. Therefore, the Flood Watch has been cancelled, but runoff and snowmelt continue and so small stream and river rises will as well. For this reason, areal Flood Warnings and Advisories remain in effect across the north.
Confidence is increasing in some convective showers/thunderstorms moving up the Connecticut River Valley around 5-6 PM ahead of a cold front. Latest HRRR runs suggest available surface based CAPE is only around 300 J/kg so wouldn't expect anything rising to the level of severe, but these showers could contain some graupel or small hail as well as brief heavy rain. Should these storms pass over the White Mountains they may aggravate the flooding situation there, but would not add any significant totals. Elsewhere instability is limited by the onshore flow, so any storms should be confined to western New Hampshire.

Patchy fog remains in the forecast through tonight as dewpoints remain elevated subsidence behind the cold front may lock in some boundary layer moisture, however the front may also scour out a lot of that low level moisture, and give us a clearer night. Either way, low temperatures look to bottom out in the 40s area wide.

SHORT TERM /SATURDAY THROUGH SATURDAY NIGHT/
Chances for rain showers will continue Saturday as the area remains under broad cyclonic flow and a secondary cold front sweeps through. Skies will remain mostly cloudy with highs in the low to mid 50s across much of the area. The aforementioned front will work to clear things out south of the mountains, but upslope snow showers look to continue across the higher terrain through the overnight hours with light accumulations possible. A period of breezy winds, 20-25 mph, is also likely in the wake of the front and as low pressure makes its final departure to the north. Low temperatures Saturday night look to be pretty uniform as cold air advection cools northern zones into the lower 30s and mostly clear skies help areas to the south cool into the low 40s.

LONG TERM /SUNDAY THROUGH FRIDAY/
Current 500 mb double omega block across NOAM mid latitudes and surrounding oceans, does start to weaken and flatten a bit a bit later this weekend, but troughing stays nearby through the week, although, we will be under W-NW zonal flow early next week which should allow for 2 or 3 mostly dry days in the period.
For the most part temps run near to a little above normal through the period. Late next week the chance for a steadier rain returns as 500 mb troughing shifts in from the west.

Sunday will feature a bit of a break with partly sunny skies as a weak ridge move across the area in the morning. Clouds are likely to increase in the afternoon, with some showers possible late in the day, especially across NH. It will be mild with highs around 50 in the mtns to 55-60 in the S. The best chance for showers across the region will be Sunday evening, as a weak, and fast moving 500 mb wave moves through. Showers will be light, and most of the CWA should see at least some clearing by daybreak. Lows range from the mid 30s to the 40s, N to S.

As we transition to more zonal flow at 500 mb on Monday, warmer air will move in but still will see some clouds as we shift away from cyclonic flow aloft. So, partly sunny covers it, but it will be a bit warmer with highs mid 50s in the mtns to low 60s in the S. It’ll be a little breezy as well with W wind gusts to 20-25 mph. As the sfc high builds to the W Monday night, it will clear out, but should enough flow to prevent widespread rad cooling, but the sheltered mtn valleys will likely decouple, and mins range from the low 30s in the mtns to the upper 30s in the S. Tuesday looks mostly sunny and even warmer, as sfc high crosses into the region with highs mid 50s in the N to mid to upper 60s in the S. WE could still eek out a decent Wed, with clouds moving in during the afternoon, although will see more onshore flow developing, especially near the coast, so while highs may climb into the low to mid 60s in the srn half of NH, they will be limited to the 50s obs the coast and in in the mtns.

As the ridge moves out Wed night into Thu, upper level trough will stretch across the NE from W to E, and this bring the potential for mainly rain across the region, potential in several rounds Thu into Fri.

AVIATION /20Z FRIDAY THROUGH WEDNESDAY/
Short Term...Low ceilings continue into tonight with some clearing likely along the coast as low pressure continues to move northward out of the area. However, patchy fog may develop in these areas as dew points remain elevated. Ceilings lower again as another cold front sweeps through Saturday afternoon.
This front will help to improve conditions back to VFR overnight Saturday, but will also keep Saturday night on the breezy side with westerly gusts to 20 kts.

Long Term...Some tempo MVFR conds are possible in SHRA late Sunday into Sunday evening, but should see VFR for the most part Mon-Wed.



MARINE
Short Term...Southerly gale force wind gusts continue through this evening before diminishing overnight. Conditions will stay hazardous to small craft through early Saturday morning, but winds will be diminishing throughout the day. A cold front crosses the waters Saturday night shifting winds westerly. This will also help to diminish seas, but they will remain in the 5-8 ft range through the overnight hours Saturday.

Long Term....SCA’s will likely need to be continued Sunday into Monday, with seas staying in the 4-6 ft range outside the bays, and borderline 25 kt gusts. Conditions eventually subside to sub-SCA criteria Tue into Wed.



GYX WATCHES/WARNINGS/ADVISORIES
ME...None.
NH...None.
MARINE...Gale Warning until 11 PM EDT this evening for ANZ150>154.
