Area Forecast Discussion National Weather Service Caribou ME 606 PM EDT Fri Sep 25 2020

SYNOPSIS. A stationary front over the Gulf of Maine will lift back north as a warm front tonight into early Saturday. High pressure will will hold over the Maritimes Saturday into Sunday. Another cold front from the west will slowly approach later Monday and Tuesday then begin to cross the region Tuesday night and Wednesday.

NEAR TERM /THROUGH SATURDAY/. 6:06 pm update: There are some mid/upper level clouds across far northern Maine associated with a weak shortwave moving out of Quebec. There are more widespread clouds around 4-5 k ft agl from around the Katahdin Region south. These clouds are associated with warm front in the Gulf of Maine. These clouds will likely begin to advance to the north overnight with the approach of the warm front. Temperatures tonight will be a good 10 to 15 degrees milder than last night, especially in the north where many of the valleys started the day in the 20s. The ongoing forecast has a good handle on the situation and no significant updates are planned at this time.

Previous discussion: Very dry air conts to hold on across the N ptn of the FA late this aftn, but this will give way to increasing cldnss and somewhat more moist air from the SW ahead of a warm front xpctd to initially slowly advc nwrd from the Gulf of ME ovrngt and then increase speed durg the erly morn hrs on Sat crossing even far NE ptns of the FA by mid Sat morn. Cannot rule out very isolated shwrs til erly eve across Cntrl highland areas, but this will be mainly a dry warm front for the Rgn.

Sat will be ptly to msly sunny behind the warm front and not as dry with well abv normal hi temps. We went a few deg warmer than traditional blended MOS guidance across the N with this guidance underestimating hi temps ovr this area the last two days with very dry antecedent soil moisture in the midst of a drought resulting in more sensible sfc htg than typical in normal rnfl regimes.

SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/. A slow moving warm front will remain north of the area from Saturday night into Sunday. This will keep the temperatures above normal for the rest of the weekend. Winds will remain from the S and light. These conditions are expected to bring fog into much of the area, except for the far N, on Saturday night and burn off by Sunday morning. A cold front is expected to approach the area by Sunday night, bringing increased clouds and mild low temperatures. Again, these conditions should be favorable for fog formation across the entire region with the possibility of some drizzle. As the cold front moves into the area on Monday, an increase chance of rain is forecasted for the region. Temperatures should remain above normal.

LONG TERM /MONDAY NIGHT THROUGH FRIDAY/. Active forecast in the extended. Strong, deep longwave upper trough over the Great Lakes very slowly approaches from the west Monday night through Friday, but the trough axis will still be a bit to our west on Friday. At the surface, a cold front will slowly approach and reach the area sometime in the late Tuesday night to Wednesday night timeframe. Ahead of the cold front, look for an anomalously warm and moist airmass with a south breeze and a lot of low clouds especially in the AM hours. Rain chances increase to likely for most areas late Tuesday night into Wednesday evening. Could be some fairly significant rain for a change as the airmass is certainly moist enough to support it. However, seeing a lot of variation among models and ensembles on timing of the front and also on the strength/speed of any potential shortwave upper level trough moving in from the SW ahead of the approaching longwave trough. Bottom line, forecast confidence on rain timing and amounts is low.

Beyond Wednesday evening, a lot of uncertainty in the forecast. Some models push the cold front through the area, leaving us in fairly dry and somewhat cooler west to southwest flow. However, other models and ensembles stall the cold front just south of us and then have another shortwave move in from the southwest along the front and bring another shot at rain with a decent surface low pressure Thursday or perhaps Friday. Temperatures slowly return to around normal toward next weekend. No snow in sight yet.

AVIATION /22Z FRIDAY THROUGH WEDNESDAY/. NEAR TERM: KBGR nwrd to KFVE - VFR with perhaps a brief pd of MVFR/IFR clgs at KBGR in oceanic ST erly Sat Morn. Lgt winds becmg mdt SSW on Sat.

KBHB - VFR this eve into the ovrngt, then becmg IFR clgs/vsbys in oceanic ST/Fog late tngt into Sat morn, then becmg VFR again late morn/midday thru aftn. Lgt winds becmg mdt SSW on Sat.

SHORT TERM: Saturday night . VFR/MVFR early. Conditions then lowering to MVFR/IFR, occasional LIFR, with low clouds and fog.

Sunday . MVFR/IFR, occasional LIFR, in the morning then VFR/MVFR. Gusty south/southwest winds. Chance of showers across southern areas.

Sunday night . VFR/MVFR early. Conditions then lowering to MVFR/IFR, occasional LIFR, with low clouds and fog. Chance of showers across entire region.

Monday through Wednesday . Generally MVFR/IFR with a chance of showers. However, LIFR also possible overnight and each morning. Gusty south winds.

MARINE. NEAR TERM: No hdlns xpctd tngt thru Sat with blended wv model guidance used for fcst wv hts with spectral wv groups including a 5 sec nwrd propagating short fetch pd and a 10 sec NE propagating open Atlc swell pd, with most of the wv energy contained in the latter.

SHORT TERM: Winds/seas will remain below small craft advisory levels through Sunday night. Visibilities will be reduced in fog Saturday through Sunday night.

A persistent southerly fetch early to midweek will lead to seas building to around 10 ft Wednesday.

FIRE WEATHER. Dry conditions are expected through the weekend. Winds are expected to increase this weekend in combination with temperatures well above normal in the mid to upper 70s. Headlines are not anticipated at this point as relative humidity is currently forecast above established thresholds. However, Sunday should be regarded as a rare fall season elevated risk day with wind gusts to 20 or 30 mph possible and temperatures in the upper 70s. Furthermore, if winds are more southwesterly, relative humidity could be lower than our current expectation. Along the coast, the fire threat will be mitigated by onshore winds. Humidity continues to climb early next week and the next chance of significant wetting rainfall will be early to mid next week.

CLIMATE. Only 0.11" of rain has been observed in Caribou, Maine so far this September. The all-time driest September on record was in 1968 when 0.86" of rain was observed. Weather records in Caribou date back to 1939. It has been even drier in Bangor with only 0.05" of rain observed this month. The driest September on record in Bangor was in 1929 when 0.64" of rain was observed. Weather records in Bangor date back to 1926. Please check the latest public information statement for a complete list of our long term climate sites this month.
