Area Forecast Discussion National Weather Service Gray ME 305 PM EDT Wed Sep 23 2020

SYNOPSIS. A cold front will sag south into the area late tonight and Thursday before returning north as a warm front by Friday. There will be very little if any relief from the ongoing drought through late this week and into the upcoming weekend before a better chance for scattered showers returns for the beginning of next week. Above normal temperatures are expected to continue through early next week.

NEAR TERM /UNTIL 6 AM THURSDAY MORNING/. Expecting a few isolated showers across northern areas through this evening as the combination of upslope flow and an approaching cold front provides weak lift. Winds will decrease after sunset as the pressure gradient between Teddy and higher pressure located to our west weakens allowing for the potential of patchy fog across mountain valleys, although this will be highly dependent upon how quickly the winds diminish. Low temperatures will be on the mild side with northern areas falling into the upper 40s while southern zones remain into the lower to middle 50s.

SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/. Patchy mountain valley fog will quickly lift by around 12Z allowing for a mostly sunny day across southern zones while northern zones remain partly cloudy. A few scattered rain showers will be possible across northern areas as upslope flow and a passing cold front will allow for marginal instability. This cold front will not result in a significant change in high temperatures as areas outside of the mountains will still warm into the middle to upper 70s, which is between 5-10 degrees above average. Winds will be lighter compared to Wednesday due to weak upper-level forcing which should help alleviate fire weather concerns some. Thursday night will remain clear to partly cloudy from south to north with low temperatures not too different from Wednesday night. An isolated rain shower will still be possible along the International Border but this activity will largely miss our area to the north.

LONG TERM /FRIDAY THROUGH WEDNESDAY/. Warm and mostly dry weather is expected through the weekend. The upper level pattern will amplify early next week with trough developing over the Great Lakes as heights build over western North America. This western ridge eastern trough configuration is expected persist for much of next week with New England in a favorable position to receive some much needed rainfall. Temperatures will run above normal into the middle of next week with chances of rain on Monday and again towards midweek as areas of low pressure track near New England into the St. Lawrence Valley.

High pressure over the western Atlantic will keep the area mainly dry through the weekend with deep southwesterly flow allowing for temperatures to run about 10 degrees above normal. Dew points in the 50s on Friday will increase slightly through the weekend reaching the low 60s by Sunday.

A short wave moving through the Great Lakes Sunday will drag a cold front through the region Monday. While throughout this ongoing dry spell these fronts have had a tendency to wash out before reaching the area resulting in limited rainfall, confidence is still moderate that much of the area will see a decent shot of rain. The increase in confidence with this front stems from the strength of the upper trough with PWATs near 200 percent of normal for this time of year. As this front clears the area Tuesday morning the upper trough over Great Lakes will deepen with a surface low bringing another shot of rain Tuesday night into Wednesday as it tracks up the St.Lawrence Valley.

AVIATION /19Z WEDNESDAY THROUGH MONDAY/. Short Term . Expecting VFR conditions across all terminals although a few mountain valley terminals such as KLEB and KHIE may drop briefly to MVFR due to low ceilings or fog between 07Z to 12Z Thursday. An isolated to scattered rain shower will also be possible through this evening across northern terminals but this activity will be widely scattered. Confidence in the entire forecast period is moderate to high with fog being the greatest uncertainty.

Long Term . Mainly VFR through the weekend. SW winds will increase ahead of a cold front late Sunday with restrictions possible in SHRA and low cigs with the front on Monday.

MARINE. Short Term . SCA conditions due to high seas and wind gusts up to 25 kts from Post Tropical Teddy expected into this evening before seas fall below 5 feet overnight and winds subside to around 10-15 kts.

Long Term . Winds and seas will remain below SCA thresholds through the weekend. SW winds will increase ahead of a cold front late Sunday into Monday with gusts approaching 25 kts. Seas will also build to 5 ft late Sunday and will continue to build into Monday night.

FIRE WEATHER. Northerly winds will diminish this evening and overnight with lighter winds of generally 10-15 mph expected on Thursday. Minimum RH values on Thursday should only bottom out into the middle 40s, however, given the very dry fuels and drought conditions, we may still highlight an elevated fire danger for portions of the area. No wetting rains are forecast over our area through this weekend.

TIDES/COASTAL FLOODING. Large, long period waves continue to impinge along the coast of Maine and New Hampshire. However, the offshore winds have taken care of any tide anomalies at this time. Therefore, have replaced the coastal flood advisory with a high surf advisory for southern beaches until 8 pm.

GYX WATCHES/WARNINGS/ADVISORIES. ME . High Surf Advisory until 8 PM EDT this evening for MEZ023-024. NH . High Surf Advisory until 8 PM EDT this evening for NHZ014. MARINE . Small Craft Advisory until 8 PM EDT this evening for ANZ150- 152>154.
