Area Forecast Discussion
National Weather Service Caribou ME
1232pm EDT Wednesday September 23 2020

Synopsis
Post-tropical cyclone Teddy will track across the Maritimes today. A cold front will cross the area Thursday then lift back north Friday. High pressure will exit across the Maritimes Saturday. A cold front will begin to approach later Sunday.

Near Term - Through Tonight
1230pm Raised high temperatures across the north based on latest trends and observations. No other changes. After coord with Maine Forest Service and WFO GYX, issued an SPS for elevated fire weather danger for the Bangor regions and portions western portions of interior Downeast.

Previous discussion... As Teddy moves northward into the Gulf of St Lawrence today and upper level ridging builds, the high clouds will gradually thin. The resultant sunshine will produce highs in the upper 60s to lower 70s with the warmest temperatures expected in the lower Penobscot Valley. A strong pressure gradient will remain on the backside of Teddy and induce strong northwest winds through the day. With 925mb winds around 25 kt, mixing to that depth or greater should generate gusts over 30 mph at times. The air mass remains dry with low relative humidity. Little rainfall fell from Teddy outside of Washington County. Thus, fire weather is the top concern today.

For tonight, there's some warm advection ahead of an approaching cold front and that will keep lows from dropping below the upper 40s to lower 50s. Some lower clouds may sweep across the far northern and western zones overnight.

Short Term - Thursday Through Friday Night
A cold front will cross the region Thursday while an upper level disturbance tracks north of Maine. Expect partly cloudy skies across northern areas Thursday, along with a slight chance of mostly afternoon showers. Across Downeast areas, expect a mostly sunny morning then a partly sunny afternoon along with a slight chance of showers. The cold front should stall across the Gulf of Maine Thursday night leaving generally partly cloudy skies across the forecast area. The stalled front should begin to lift back north across the region in the form of a warm front Friday into Friday night. Expect partly cloudy skies Friday along with a slight chance of mostly afternoon showers. Clouds increase across northern areas Friday night with still a slight chance of showers, with partly cloudy skies Downeast. Temperatures will be at slightly above normal levels Thursday/Friday.

Long Term - Saturday Through Tuesday
The warm front will lift north of the region early Saturday, with a cold front then approaching northern areas Saturday night. Expect mostly cloudy skies and possibly the slight chance of a shower across northern areas early Saturday, with a partly cloudy afternoon. Across Downeast areas, expect a partly cloudy morning then a mostly sunny afternoon Saturday. Clouds then increase across the entire region Saturday night with a chance of showers late. Low pressure approaching from the west will draw a cold/occluded front toward the region Sunday. Expect mostly cloudy skies along with a chance of showers Sunday. The cold/occluded front should stall across the region Sunday night into Monday keeping mostly cloudy skies along with a chance of rain across the forecast area. The front should begin to lift north Tuesday in response to strong low pressure moving east across the Great Lakes. The approaching surface low and upper trough will begin to draw moisture north Tuesday with increasing rain chances late. Temperatures will be at above normal levels Saturday through Tuesday.

Marine
NEAR TERM: 10 am Have downgraded the remaining GLW's to an SCA.

SCA (Small Craft Advisory) conditions will continue into this evening. Both the long period southeast swell and the short period wind driven northeasterly seas will diminish this morning. Nearshore buoys have mostly been capturing the shorter period seas, but that's typical.

Short Term: Winds/seas will be below small craft advisory levels Thursday through Friday night.

Fire Weather
Relative humidity will remain above headline criteria, but it's not far off. With northwest winds gusting over 30 mph and the lack of precipitation from Teddy outside of Washington County, fire weather remains a concern today. Highs today will be in the upper 60s to lower 70s with some sunshine developing as the high clouds gradually thin out. The lower Penobscot Valley will have the overall best combination of winds, low relative humidity and temperature. Only a few hundredths of an inch of rainfall has fallen since late August in that area.

Tides / Coastal Flooding
550amCancelled the Coastal Flood Warning in favor of a High Surf Advisory as long period southeast swell will continue to affect the coast today, but the threat of any overwash with this afternoon's high tide is negligible.

The high tide occurred at 4am this morning and any overwash on coastal roads has now occurred. The next high tide this afternoon is expected to have little impact, but high surf from Teddy will continue today. Thus, upon expiration of the current Coastal Flood Warning, a High Surf Advisory may be needed for the rest of the day.

NOAA Caribou ME Office - Watches - Warnings - Advisories
ME...High Surf Advisory until 8pm EDT this evening for MEZ029-030.
MARINE...
Small Craft Advisory until 8pm EDT this evening for ANZ050>052.
