Area Forecast Discussion National Weather Service Gray ME 629 AM EDT Sat Jun 22 2024

SYNOPSIS
A cold front will stall over Southern New England through tonight as weak waves of low pressure ride along it. This will result in a showery morning today with highs today below normal at most locations. A warm front will attempt to move northward through the forecast area on Sunday with a chance of showers and thunderstorms. A few thunderstorms may be severe across New Hampshire. Another front will then cross on Monday with additional unsettled weather before high pressure builds towards the middle of next week bringing warmer weather.

NEAR TERM /UNTIL 6 PM THIS EVENING/
625 AM Update...Showers, locally heavy continue across most zones except the far south this morning. However, a few thunderstorms developing over central NY could affect southwestern NH over the next several hours with very heavy downpours. If not that current batch of storms, there will be another shot early to mid afternoon there. Mainly in Cheshire County. Other than that, based on latest CAMs, HRRR, and SPC outlook have added damaging winds to the thunderstorm descriptor for most of NH for tomorrow (Sunday afternoon and early evening).

Previously...

A weak short wave trough and falling heights early this morning has aided in triggering showers across the region, mainly north of a KLEB-KPWM line. These will gradually move southeastward this morning as the attendant short wave trough moves southeastward as well. The threat for excessive rainfall has seemed to diminish fairly substantially as forcing for ascent and elevated instability remains quite weak. The PWATS are relatively high however, so some heavy downpours with local poor drainage flooding still isn't out of the question as long as precipitation takes on a more convective appearance.

This main batch of showers will continue southeastward and exit the coast near PWM by noontime. However, continued scattered showers are expected across northern and central zones throughout much of the day. Of course the clouds and showers and east winds will keep temperatures down today, with lots of highs in the 60s expected.

The exception may be southwesternmost NH where heating may be sufficient for a few strong thunderstorms this afternoon as indicated by a few CAM runs. Gusty winds and torrential downpours would be the main threats with these storms. However this is conditional upon SFC heating.

SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY NIGHT/
WAA, at least aloft, continues tonight with forcing for ascent sufficient for more showers, some potentially heavy given the high PWATS. A few thunderstorms will be possible overnight as well as marginally unstable conditions develop aloft. Fog, especially along the coast is probable as well.

Warm front attempts to make northward headway into our forecast area on Sunday. Models tend to overforecast the northward advancement of warm fronts in northern New England. However, an anomalously strong southwesterly LLJ will be present and this should help it move through at least central and western NH by Sunday afternoon. North and east of there, it will likely remain more stable with highs again in the 60s, especially into many of our Maine zones except perhaps York County and portions of Cumberland County. However, this could change depending on speed and strength of parent low pressure to our north.

The SPC has placed a good portion of NH in a slight risk for severe thunderstorms on Sunday. This is mainly driven by the convective wind threat due to the strong LLJ, but also note the 5% tornado risk as well. A few models show impressive hodographs in NH. Will continue to monitor as the threat remains fluid and conditional upon warm front disposition and speed of approaching cold front (timing could be off).

LONG TERM /MONDAY THROUGH FRIDAY/
Key Messages -

* Any strong storms come to an end Sunday night with unsettled/showery conditions through Monday.

* Dry and warmer Tuesday and Wednesday.

* Strong cold front arrives Wednesday night with showers and a few thunderstorms before cooler temperatures arrive for the end of the week.

--Pattern and Summary--

Troughing moves overheat Sunday night in to Monday with shortwave ridging quickly building in it/s wake as we move towards the midweek ahead of Canadian troughing that will be digging into the Great Lakes region. This second trough looks to arrive to end the week
Thus
the forecast looks to open unsettled before turning warmer and drier through midweek. The most impactful weather will arrive Wednesday night into Thursday as the reinforcing trough arrives with it/s associated cold frontal boundary with temperatures falling to end the week.

--Daily Details--

Unsettled conditions look to continue behind any convection Sunday night into Monday as shortwave trough and associated mid level forcing for ascent arrives from the west. The guidance suite differs on the eventual track of low pressure Sunday night and Monday with the arriving trough causing the low to slow...and potentially cross the CWA through Monday
Thus
expect showers to remain in the forecast with some potential for some isolated thunderstorms with temperatures near or a bit below seasonal norms depending on shower coverage.

High pressure builds in for Tuesday-Wednesday with T8s rebounding to around +15C on Tuesday...and then up another 1-2C for the day Wednesday. This should allow widespread 80s for highs on Tuesday with highs south of the mountains building into the upper 80s to potentially near 90 on Wednesday. Dewpoints in the 60s will prevent heat indices from moving much above high temperature values...so do not expect heat headlines for Wednesday.

Next cold front arrives Wednesday night which will take temperatures back closer towards seasonal norms to end the forecast period Thursday and Friday. A quicker frontal passage would introduce severe weather potential late Wednesday...with an overnight passage still bringing thunder...though a much lower threat for any severe weather.

AVIATION /12Z SATURDAY THROUGH WEDNESDAY/
Short Term
Today through Sunday
MVFR to local IFR conditions are expected today, in low clouds and showers/isold thunder. A few breaks to VFR will be possible later this morning and this afternoon, especially at northern terminals. CIGS lower to IFR with areas of LIFR tonight in low clouds and showers, with some restrictions due to fog also. CIGS and VSBYS improve to VFR from south to north Sunday afternoon as a warm front moves northward. However, KAUG and KRKD will likely remain low. Showers and thunderstorms are expected Sunday, especially late afternoon and evening and some could be strong, with strong SFC wind gusts. LLWS possible later tonight and Sunday with strong southwesterly LLJ developing.

Long Term
After evening thunderstorms Sunday
MVFR/IFR restrictions are likely for the overnight as fog develops given moist low level conditions. Showery conditions continue on Monday with MVFR restrictions possible. Improvement to VFR is expected for Tuesday and Wednesday.

MARINE
Short Term...Easterly flow continues through today, with conditions remaining below SCA levels. Patchy dense fog is possible as a warm front lifts across the waters. Winds turn more southerly later tonight as a warm front begins to lift across the region. Southwesterly winds possibly increase to SCA levels on Sunday.

Long Term
Residual SCA conditions possible Sunday night
esp for the outer waters with diminishing winds/waves Monday as low pressure tough moves overhead. Southerly winds strengthen Wednesday with SCAs possible by late in the day.
