Area Forecast Discussion National Weather Service Gray ME 1151 AM EDT Fri Jun 21 2024

SYNOPSIS
A cold front will stall over Southern New England today through Sunday as waves of low pressure ride along it. This will result in near seasonable temperatures and rounds of scattered showers and thunderstorms. Another front will then cross on Monday with additional unsettled weather before high pressure builds towards the middle of next week.

NEAR TERM /UNTIL 6 PM THIS EVENING/

11:50am Update... Continued to adjust for POPs today as the front slowly progresses southwestward. Also worked to adjust temps based on increasing breaks of sun behind the front.
Scattered showers continue to develop along and behind the front, and are expected to become more numerous with some scattered thunderstorms as well as the front encounters warmer air across central and southern New Hampshire.

8:25am Update... A quick update to increase POPs for this morning for the scattered showery activity developing with the passing cold front. An isolated thunderstorm is also possible near the ME/NH border over the next few hours.

645 AM Update... A few isolated showers have developed within the Portland Metro and therefore adjusted PoPs to account for these. Latest CAM guidance indicates a somewhat growing potential for some modest destabilization to occur later today over southern NH and there is a decent amount of bulk shear present and therefore while the threat for a severe storm is low, cannot rule out one or two gusty storms this afternoon...
especially in southwestern part of the state.

Previously...
Satellite imagery this morning shows an area of mid-level clouds streaming from northwest to southeast over the region and radar shows an area of showers dropping southeastward over interior western ME. Patchy fog and low ceilings have developed across portions of the region, especially over valley sites and this will continue to be possible through 7am or so. Current temperatures are primarily into the upper 60s and lower 70s with another degree or two of cooling possible through daybreak. It will otherwise continue to be a warm and humid start to the day.

The cold front that was responsible for yesterday's severe weather is progged to become stationary over southern New England today, putting our area into the cool sector. This will result in significantly cooler high temperatures compared to the last few days with readings topping out into the upper 70s to lower 80s for most areas. Skies will be partly sunny across much of western ME and partly to mostly cloudy over NH. A weak wave of energy will ride along this boundary through the day, which will result in scattered showers and perhaps rumbles of thunder over NH while much of western ME remains dry under light northeasterly sfc flow.

Scattered showers will become more likely areawide tonight, especially after midnight as a vorticity maximum crosses the area... providing some extra lift. Rainfall amounts are expected to be light with generally between 0.10-0.25". Low temperatures will range from the middle 50s across the north to lower and middle 60s south. Patchy fog may develop as well given the light flow and abundant LL moisture.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/
The stationary front will slowly begin to retreat northward on Saturday as another wave of low pressure rides along it from the west. Skies will be partly to mostly cloudy with scattered showers and isolated thunderstorms areawide. An additional 0.10-0.25" of rainfall can be expected in most locations.
Locally higher amounts will be possible though, especially over the mountains. High temperatures will be cool given the cloud cover and onshore flow with readings along the coast only into the 60s and then lower to perhaps middle 70s over the interior.
The warmest area will likely be southwestern NH which could approach the 80 degree mark.

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/
Overview: Relatively progressive flow after the NE CONUS ridge becomes suppressed with a more active polar jet stream and Canadian troughs moving across New England. Shortwave ridging is expected between the troughs bringing a see-saw weather pattern over the next week. This will bring periods of active weather with thunderstorms and temperature swings from near normal to above normal.

Impacts: There is the potential for localized flash flooding on Sunday across the mountains. In addition, severe weather can't be ruled out Sunday at this time across most of the forecast area.

Forecast Details: By Sunday the stationary boundary becomes a warm front and surges north of the area bringing the region back into the warm sector. Threat for severe weather will increase as a robust mid-level shortwave and associated cold front pushes through the area sometime late Sunday into Monday morning.
There is some model spread on the order of 12 hours or so on timing of FROPA at this time. Monday the shortwave trough swings through with the potential for much cooler weather and showers, but this depends on the timing of the trough. Tuesday looks to have the highest potential for being the driest day of the week as a shortwave ridge moves over the area with a rebound in the temperatures. Wednesday could be warm once again as a return to southwest flow is possible ahead of the next approaching trough.
A period of storms is possible in the Wednesday night into Thursday timeframe as the next cold front swings through the area.

AVIATION /16Z FRIDAY THROUGH TUESDAY/
Short Term...Mainly VFR conditions can be expected today with scattered -SHRA at times, mainly across NH TAF sites. More widespread -SHRA arrives tonight along with low ceilings/FG which will likely result in IFR to LIFR restrictions at times.
Conditions slowly improve on Saturday but MVFR CIGS could linger through much of the day. Winds will be light out of the NE today then ESE on Saturday. No LLWS is expected.

Long Term...Showers and thunderstorms could bring temporary MVFR to IFR conditions on Sunday as the threat for afternoon thunderstorms increases along with gusty southwest winds. Storm coverage should trend downward by the beginning of next week.

MARINE
Short Term...Onshore winds and seas to remain below SCA thresholds through the period as a front stalls south of the waters.

Long Term... By Sunday strong SW winds could develop leading to marginal SCA conditions by the afternoon and evening hours ahead of an approaching cold front. Cold front pushes through on Monday with a return to offshore flow and possible SCA conditions.

GYX WATCHES/WARNINGS/ADVISORIES
ME...None.
NH...None.
MARINE...None.
