Area Forecast Discussion National Weather Service Caribou ME 1149 PM EDT Mon May 20 2024
SYNOPSIS
High pressure will ridge across the region through Tuesday, then build south of the area through the middle of the week. A strong cold front will cross the area Thursday, followed by high pressure Friday into next weekend.
NEAR TERM /THROUGH TUESDAY/
Update...
The main challenge overnight will be how far inland stratus/fog makes it by daybreak. Latest observations showing low stratus has made its way into the Bar Harbor airport. Nighttime satellite imagery shows it creeping toward Bangor.
Otherwise quite the temperature contrast at this hour with mid 60s across the north. Closer to the coast, only in the low 50s thanks to a cool breeze off the Gulf of Maine.
No significant adjustments needed this hour.
See updated aviation section below.
Previous Discussion: The axis of the upper level ridge will begin to sag to the south tonight. Expect another night of gradually increasing stratus desk with the onshore flow with patchy fog across the region.
Temps will be in the upper 50s in the north and upper 40s in the south.
For Tuesday, the upper level ridge will continue to influence the region with a vort max, currently over the Great Plains, moving NE towards the area. For Tuesday morning, patchy fog will dissipate early, then clouds should start to break with the increasing heat of the day. By the afternoon, rain showers will begin, but the high-res and CAMs models are inconsistent with the timing of the convection across the region. Instability values across the north are concerning for thunderstorms, including some becoming severe. With the steep lapse rates, the skinny CAPE giving a very moist column, high mid and low level RH, and PWATS above normal, heavy rain is expected with the storms. In addition, an inverted V sounding and elevated DCAPE indicate that some storms will contain gusty winds. Depending on the high temps and breaks in the clouds, these storms have the potential to last into late evening. Temps will reach into the lows 80s across the region, expect Downeast where temps range from mid 70s inland to mid 60s on the coast.
SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/
In general, a powerful upper ridge will continue to dominate area weather through the period with subsidence and warming.
The warmest temperatures of the year can be expected during the period with highs reaching the 80s and lows over 60F for large portions of the forecast area by Tuesday and Wednesday nights.
A series of weak fronts riding the northern periphery of the ridge through the period represents the forecast challenge in terms of thunderstorms and exact hi/low temperatures Tuesday night into Wednesday.
On Tuesday night, expect a convective disturbance currently in the western Great Lakes region to ride over the upper ridge and into northern zones with thunderstorms. Guidance continues to offer a wide variety of timing and intensity solutions for the compact shortwave embedded in the flow. It is still unclear if an MCS will develop and track across southern Quebec Tuesday afternoon. The majority of guidance has the disturbance arriving Tuesday evening and affecting the forecast area well into the night. Thunderstorms are definitely a threat with locally heavy downpours, but timing well past peak heating reduces interest in any enhanced wording for Tuesday evening/night.
Lows in the northern half of the forecast area will be near 60F while an onshore flow of cool marine air will drop coastal lows towards 50F with the threat of fog.
The frontal boundary location remains the nexus between temperature and PoP forecasts into Wednesday. At this point, have played for nominally cooler highs in northern zones due to the lingering boundary, but mid to upper 80s or higher seems likely for the Bangor area. If the frontal boundary moves northward more rapidly, these mid 80s may extend northward across the entire forecast area. In terms of convection, expect the upper level ridge to build on Wednesday and cap convection.
Did mention a slight chance of afternoon thunderstorms in case the cap breaks or there is a large timing error regarding the disturbance expected Wednesday night. SBCAPE numbers could be rather impressive by later Wednesday afternoon.
This instability continues into Wednesday night. Thunderstorms are again a threat for Wednesday night as a weakening warm occlusion moves through the area. Clouds, precip and warm advection will keep lows in the 60s and humidity will reach its zenith so far this year with dew points in the lower to mid 60s.
These dew points will continue ahead of a strong cold front on Thursday. The cold front will act a potent trigger for widespread convection. All of the ingredients for an active day seem to be in place: CAPE, strong shear and anomalously high PWs. About the only issues to lessen severe potential will be unfavorable early timing for the frontal passage and persistent early morning clouds behind the occlusion. It has been quite a few years since we have seen a favorable setup for severe weather in late May. The hydro aspect will also have to be watched given the deep moisture.
LONG TERM /THURSDAY NIGHT THROUGH MONDAY/
The front will exit quite quickly Thursday night and bring very welcome relief in terms of temperatures and dew points for Friday and throughout next weekend. There will still be the chance of showers with a secondary cold front and upper trough on Friday. The 20/12Z GFS is now suggesting the threat of another round of thunderstorms Friday afternoon with the secondary front, but it is not well supported by other guidance at this point. Highs return to the 60s to around 70F for the holiday weekend with lows in the 40s.
AVIATION /04Z TUESDAY THROUGH SATURDAY/
NEAR TERM: Aroostook Terminals...Mainly VFR tonight, then possible IFR/MVFR cigs for HUL and PQI depending on if low clouds and patchy fog reach this far north.
For Tuesday, VFR conditions with possible isolated showers and thunderstorms in the afternoon.
Downeast Terminals...Developing IFR/LIFR expected for BGR/BHB in low cloud and fog, with highest confidence vcnty BHB.
By Tuesday morning, ceilings and coastal fog should lift making for VFR conditions the rest of the day.
Light south winds at all terminals tonight, becoming SSW to SW around 10 kt during the day Tuesday.
SHORT TERM: Tuesday night...VFR except a slight chance of fog at BHB. Light south winds.
Wednesday...VFR with a slight chance of afternoon thunderstorms.
Light south winds.
Wednesday night...Predominately VFR with a chance of thunderstorms. A slight chance of fog at BHB. A chance of MVFR tempo IFR cigs later in the night north of HUL. Light south winds.
Thursday...VFR tempo IFR in strong thunderstorms along a cold front. Light south winds outside of thunderstorms.
Thursday night into Saturday...VFR with tempo MVFR cigs possible north of HUL early Friday. Scattered showers possible north of HUL.
MARINE
NEAR TERM: Winds and seas will remain below SCA conditions tonight and Tuesday. Areas of fog will reduce visibility.
SHORT TERM: Warm and relatively humid air moving over the cold waters is likely to cause fog at times Tuesday night into Thursday night. The stability will reduce winds and seas through next week. In general, southwest winds around 10 to 15 kt can be expected until Friday night when winds will become more westerly. By Saturday night, winds will become more northerly. Seas will mostly run 2 to 4 feet, but become 1 to 2 feet this weekend as high pressure builds over the waters.
