Area Forecast Discussion National Weather Service Gray ME 954 AM EDT Tue Apr 23 2024

SYNOPSIS
High pressure slides south of the area today for warmer and dry conditions. Low pressure approaches the region Wednesday bringing the next chance for rain. High pressure then builds in towards the end of the week. A warming trend can be expected over the weekend with chance of showers.

NEAR TERM /UNTIL 6 PM THIS EVENING/
945am Update...Not many changes to going forecast. Current obs show that the coast and just inland have warmed the quickest, passing through the upper 40s and lower 50s at this hour. Mixing should kick off shortly, with breeze increasing.

640 AM Update...Minor update to T/Tds to reflect observational trends.

Previously...

High pressure aligned along the East Coast this morning will shift out into the Atlantic today while providing fair weather. As the high shifts offshore southerly winds will increase through the day with gusts topping out around 25 mph inland and closer to 30 mph along the coast. These onshore winds will keep highs in the 50s across much of Maine while portions of interior NH climb into the mid 60s. There will be some increase in moisture across the area while overall the airmass will remain dry leading to elevated fire weather conditions as min RH drops to around 30 percent across Maine and 25 percent across NH.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/
An upper trough will swing across the Great Lakes region tonight generating an area of low pressure that will approach the region Wednesday morning. This system will bring increasing clouds with increasing chances for rain across northern and western zones. Lows tonight will range from mid 30s across much of Maine to around 40 degrees across southern and western NH.

The 00Z model suite generally tracks the surface low west to east across the area Wednesday bringing periods of rain to the area with a cold front sweeping across the area Wednesday afternoon. This will bring colder air into NW zones allowing for rain to change to snow in the mountains and then to valley floors before precipitation ends Wednesday evening. Overall, QPF will be light on the order of 0.25 inches with higher amounts in the mountains. Areas south of the mountains may only see a few hours of rain Wednesday morning into early afternoon with drying mid to late afternoon. The highest summits could see an inch or two of snowfall with northern valleys seeing a coating of snow. Highs will range from the 40s north to 50s south with these high temperatures being realized around mid day with temperatures falling during the afternoon.

LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/
Strong cold air advection Wednesday evening will allow for any precipitation to end as a few scattered snow showers across the region. Drier air on downslope northwesterly winds will lead to clear skies outside the mountains during the overnight hours as high pressure from Canada begins to nose into the region.
Temperatures will drop into the 20s in all areas by morning on brisk winds.

The gradient will diminish considerably on Thursday as high pressure continues to build over the region. However, significant mixing will allow for a west to northwesterly flow to continue and preventing the formation of a sea breeze in most areas.

After an afternoon reaching the 50s on Thursday, Friday will be a few degrees warmer away from the coast with readings reaching near 60 degrees over southern interior locations. This warming trend will continue into the weekend as a southwesterly flow develops around the periphery of high pressure located off the east coast. Widespread lower to mid 60s can be expected with the exception of cooler temperatures along the coastline due to a late morning and afternoon sea breeze. The warmth culminates on Sunday and into early next week with 70s across southern interior locations. It will continue to be cooler along the coastline due to a sea breeze with the Midcoast region particularly chilly. There will also be considerable cloudiness during this period with scattered showers across the region, mainly during the afternoon hours as models suggest a nearly stationary front will remain over the region.

AVIATION /14Z TUESDAY THROUGH SATURDAY/
Short Term...VFR will prevail today with south winds gusting to around 20 kts by late morning. VFR likely continues through the first part of tonight followed by lowering cigs from NW to SE into Wednesday morning. Low cigs and -RA will likely bring MVFR conditions for much of Wednesday.

Long Term...Mainly VFR conditions through the end of the week.
Scattered showers will lead to MVFR conditions at times Sunday and through the beginning portions of next week. This will mainly be during the afternoon hours.

MARINE
Short Term...High pressure shifts east of the waters with increasing southerly flow. This south flow will bring a period of SCA conditions from Port Clyde southward. There will be a resurgence of south to southwest winds Wednesday ahead of a cold front with gusts approaching 25 kts and seas building 5-6 feet by Wednesday afternoon.

Long Term...Winds will gust into SCA thresholds Wednesday night with cold air advection on an increased northwesterly flow.
Winds and seas subside thereafter and become locally onshore during the afternoon hours.

GYX WATCHES/WARNINGS/ADVISORIES
ME...None.
NH...None.
MARINE...Small Craft Advisory from 2 PM this afternoon to 8 PM EDT this evening for ANZ152-154.
