SYNOPSIS
Very warm conditions continue through Thursday with a cold front bringing scattered thunderstorms Thursday afternoon. Drier air arrives Friday with mostly dry weather into Saturday. A frontal system brings chances for showers late Saturday into Sunday. A more organized system approaches for early next week bring better chances for widespread showers late Monday into Tuesday.
NEAR TERM /UNTIL 6 AM THURSDAY MORNING/
1020 PM Update...No changes to the forecast at this time. A mostly clear and warm evening continues. A few showers and perhaps a rumble of thunder may affect western zones later on tonight.
715 PM Update...Little change to the going forecast this evening. MOstly clear skies are likely to continue into the weekend along with light winds and warm temperatures. Showers and thunderstorms over Upstate NY should gradually weaken over the next few hours with loss of daytime heating. Will still watch for some widely sct activity getting into the CT River zones late this evening or overnight.
Previously...
Mid level ridge axis is cresting over northern New England this afternoon making for very warm conditions across the area with temperatures in upper 80s to low 90s. Latest satellite shows CU have blossomed over the higher terrain of Maine and New Hampshire with some attempt of CU developing along the sea breeze boundary from interior York County through interior Waldo County. CAMs suggest that an isolated shower or thunderstorm cannot be ruled out along this boundary through sunset with the best chances toward central Maine.
Tonight will be mild and humid with temperatures and dewpoints generally staying in the low 60s. There may be enough SW flow ahead of an approaching cold front to limit fog potential with the best chances for fog near the Mid Coast. The approaching front is currently triggering convection over PA and western NY with some CAM solutions suggesting this remnant convection will spill into northern and western zones tonight. There is a fair amount of spread in guidance as to how widespread this shower and thunderstorm activity will be and have generally carried chance PoPs across northern zones and much of NH with this activity weakening as it moves east into Maine. There will be limited instability overnight night limiting the potential for any strong thunderstorms.
SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY/
The cold front will be entering NW zones Thursday morning and will push into the coastal Plain in the afternoon. The 12Z HRRR mean brings MU CAPE into the 1000-1500 J/kg range ahead of the front with deep layer shear of 35-40 kts. Some individual HRRR members bring MU CAPE greater than 2000 J/kg along the coastal plain early tomorrow afternoon. This convective parameter space will favor strong to severe storms while the prior to peak heating passage of the front should limit overall coverage of storms. SPC maintains a Marginal Risk for severe storms south of the mountains to the coast where the best instability will be.
The 12Z CAM suite suggest storms could fire by mid day along the foothills and strengthen as these storms track to the coast between 2 PM to 5 PM. Instability drops off after 5 PM with convection waning into sunset. The hazards from strong to severe storms will be strong damaging winds and hail.
Drier air works into the region Thursday night behind the front. Lows will range from the low 50s north to near 60 degrees across the south.
LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/
Friday isn't looking quite as dry as it did this time yesterday with models trending a bit farther south 500mb trough swinging across southern Quebec. This will send another weak frontal boundary through during the day, and although moisture is rather limited, there could be a few showers out of this, primarily across northern areas (20-30% chances). Outside of showers, it will still be rather warm with temperatures away from the immediate coast again reaching the 80s for much of the area.
Somewhat breezy conditions to around 25 mph at times per BUFKIT forecast soundings should offer some relief.
Once this wave and front pass, we get a ridge briefly build in Friday night and Saturday, keeping things mostly dry along with the continued warmth. Temps again Saturday look to reach the mid 70s to lower 80s for most of the area.
Late in the day and into Saturday night, a weak wave aloft and broad area of low pressure will bring another opportunity for showers through Sunday morning, but amounts look light with ensemble means from the GFS and ECMWF both indicating amounts in the 0.10-0.25" range. Depending if this low remains close enough nearby on Sunday, a few showers may again develop during the afternoon.
Models are showing good continuity for early next week with a low pressure system setting up over or just north of the Great Lakes region. While they have shied away from the coastal low scenario for the most part, a cold front looks to be sent toward New England, bringing the next potential for widespread rainfall across the area in the Monday-Tuesday timeframe. There are also signals for heavy rainfall out of this system as ensembles from the ECMWF/GFS are already showing decent probabilities for PWATs in excess of 1.50", but we'll watch trends over the coming days. Another wave could follow quickly behind the front, so there is uncertainty if next Wednesday will be dry or not.
AVIATION /03Z THURSDAY THROUGH MONDAY/
Short Term...Mainly VFR tonight across the area except for some potential for fog at KAUG and KRKD, although confidence is low.
A cold front brings scattered TS to the area tomorrow with the best chance for TS along and south of a line from KCON to KAUG.
Timing of TS is around 18Z to 22Z Thursday afternoon. Drier air arrives Thursday night for mainly VFR.
Long Term...Mainly VFR Friday, but a few showers are possible as another weak frontal boundary crosses, mainly north of the TAF sites. Going into the weekend, with southerly flow continuing, marine fog/stratus may impact the coastal sites, but this is of low confidence. Additional showers also look to arrive late Saturday and into Sunday with a higher potential for more widespread rainfall and flight restrictions early next week.
MARINE
Short Term...Winds will predominantly be out of the S to SW tonight through Thursday while winds and seas remain below SCA thresholds. A cold front pushes into the waters Thursday afternoon with a few strong to severe storms possibly tracking off land into the waters. Winds shift westerly Thursday night behind the front.
Long Term...W/SW flow starts out Friday but will gradually become more southerly by the afternoon. Winds will then switch to northerly late in the day into Friday night as another frontal boundary crosses but remaining below SCA levels. High pressure becomes centered southeast of the waters over the weekend leading to a prevailing southerly flow with fog possible at times. A weak low pressure may bring some showers late Saturday and into Sunday. Going into early next week, a more potent low pressure north of the Great Lakes will send a cold front toward New England with increasing south to southeast winds potentially surpassing SCA levels late Monday into Tuesday.
