Area Forecast Discussion National Weather Service Gray ME 108 PM EDT Sun Apr 18 2021

SYNOPSIS. Warmer temperatures are expected today but there may be a couple of showers this afternoon. Temperatures will continue to moderate Monday and Tuesday before low pressure returns unsettled weather midweek followed by cooler conditions.

NEAR TERM /TODAY/. 100 PM Update . Did another quick round of tweaks for today's temperatures according to observed trends but overall the forecast remains on track. Currently, a mix of sun and clouds over the region . with more breaks/cu leading to better warming in portions of southern New Hampshire and the Mid-Coast of Maine while greater coverage/stratocu is stunting the diurnal warming trend for portions of northern NH, western Maine, and western NH. Low topped, convective showers are forming over the Adirondacks and are set to shift SE ward toward the mid- Connecticut River Valley later in the day before decaying tonight over southern NH.

1030 AM Update . Made just a few minor edits to today's forecast, mainly to PoP/Sky and corresponding temperatures according to 12Z hires data coming in. Added isolated showers across the north into the afternoon and fine tuned PoP over New Hampshire with a convergence zone leading to some light ridge-rolling shower activity zone later this afternoon and evening over the southwest part of the state.

7AM UPDATE . Made only minor adjustments to the gridded forecast based on latest observations. Clouds have been in and out through the morning and expect that to continue with more clouds than not expected.

ORIGINAL DISCUSSION . Low pressure continues to pull away today to the east while a very broad high pressure region builds in. Without much in the way of subsident flow to clear things out, we'll continue to see a fair amount of cloud cover with temperatures cool but a bit warmer than yesterday. A stray shower is possible in the afternoon, especially in the west. Although widespread shower activity looks less likely.

SHORT TERM /TONIGHT THROUGH MONDAY/. We remain under broad high pressure tonight with a fair amount of cloudiness and temperatures only falling into the 30s for most. On Monday a subtle shortwave trough combines with continued bottom up warming to bring a chance of showers during the afternoon. High temperatures reach the 60s.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/. Any lingering isolated showers will dissipate very early in the evening on Monday. A cold front will approach from the west on Tuesday but much of the best forcing for ascent looks to pass north of our forecast area. Even still, there may be a few showers in the mountains. There will be a stout westerly low level jet Tuesday as well, and this looks to result in a gusty day with wind gusts over 30 MPH possible. Temperatures look to rise well into the 60s, with some 70s in the south expected.

The cold front sags southward through the forecast area Tuesday night. At the same time a short wave trough will approach from the west and the cold front will begin returning northward as a warm front. This may allow for increasing chances of precipitation across mainly western zones late Tuesday night. Any precipitation will be light and mostly in the form of rain. However, the column may be cold enough in the mountains to allow for a little light snow.

The short wave trough to our west continues to amplify as it heads toward our forecast area on Wednesday. This will aid in a strengthening low pressure system and attendant cold front to move across the forecast area later Wednesday and Wednesday night. There remains timing differences with the passage of the front, but most solutions do bring a period of beneficial rains, especially across western and northern zones. Ahead of the front on Wednesday, a southerly low level jet will strengthen and will likely result in gusty winds during the afternoon. As the front passes, westerly winds will likely be strong and gusty for a time later Wednesday night into Thursday. In addition, the rain could change to snow in the mountains Wednesday night with a low probability of accumulating snow.

Thereafter, cooler and drier conditions are expected.

AVIATION /17Z SUNDAY THROUGH THURSDAY/. Short Term . Mostly VFR conditions expected with clouds coming in and out mainly around 5000 FT. However, some areas of MVFR ceilings will be possible early this morning across western Maine. Light winds and VFR continues through Monday, although a stray shower will be possible in the afternoon.

Long Term . Generally MVFR Monday night and Tuesday with isolated areas of MVFR in localized showers. MVFR gives way to a areas of IFR late Wednesday into Thursday as low pressure moves east and rain develops late. LLWS will be possible Wednesday as a southwesterly low level jet picks up. In addition, SFC gusts on Tuesday may approach 30 knots from the west.

MARINE. Short Term . Light winds and calming seas expected as high pressure builds in.

Long Term . Westerly winds ahead of a cold front Tuesday may allow for SCA conditions. A strong cold front will approach from the west on Wednesday and this will kick up the winds and seas late Wednesday through Thursday. Low-end westerly gales will be possible later Wednesday night and Thursday in the wake of the strong cold front.
