Synopsis for stonington me to merrimack river ma out to 25 nm high pressure will become centered over the waters for the next several days,an area of low pressure is expected to move offshore of the mid- atlantic by early Saturday before lifting to the northeast and remaining east of the waters through Sunday. Broad high pressure is forecast to becoming centered over the western atlantic early next week bringing a more southerly flow back across the waters.

Area Forecast Discussion National Weather Service Gray ME 408 AM EDT Thu May 9 2024

SYNOPSIS
Several cool and unsettled days are in store as a warm front remains south of most of our forecast area and moist onshore wind flow continues. Another system follows for the end of the week, bringing more showers into the forecast. The unsettled, showery pattern may continue through the weekend and possibly into early next week. No days will be washouts, just cool and cloudy with occasional showers.

NEAR TERM /UNTIL 6 PM THIS EVENING/
No real changes to the going forecast. As is typical in Maine springtime is periods of cloudy, cool, and occasionally showery/drizzly/foggy conditions at times. That's the type of pattern we are in now unfortunately. Went with highs about 10 degrees below normal today with cloudy skies and deep onshore or northerly flow depending on location. There won't likely be much in the way of measurable rainfall, but it won't exactly be pretty.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/
Same pattern continues for tonight and Friday. Cloudy skies with colder than normal temperatures are expected despite little in the way of measurable precipitation. The best chance for seeing breaks in the clouds will be tonight and Friday morning. Expect patchy fog tonight, especially where skies can go mostly clear for a time.

LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/
Overview: Most weather systems in the extended forecast remain outside our immediate area, but unsettled conditions prevail regardless. Low pressure will pass east of New England over the open Atlantic Saturday. High pressure could build into northern New England for the remainder of the weekend, but uncertainty exists how much dry air this may bring. A greater chance for widespread precipitation exists entering midweek next week.

Details: Precip continues a further south and west trend into interior Northeast Friday night. This will eventually phase across the Mid-Atlantic with low pressure tracking over the open Atlantic along the east coast. There will be enough moisture over Maine and New Hampshire in the mid levels for continued cloud cover in the region, but measurable precip appears unlikely for the first half of the weekend.

Saturday, area of low pressure will be well off the coast.
Cyclonic flow will be at the surface here, meaning cooler and drier NE flow. Pesky mid moisture will still be here however, and diurnal mixing may prove the outside chance of a few showers popping up in the afternoon. With so much dry air near the surface, doubtful these produce much in the way of measurable precip, but will be interesting to follow CAMs if they develop showers.

Guidance has some noticeable discrepancies overnight into Sunday, mainly how the offshore low is handled. This has implications for precip into early next week. Little consistency to be found amid the major globals and their ensembles here.
Some troughing on the backside as the low lifts towards Nova Scotia could bring more persistent showers overnight into Sunday. Should the low keep a flatter path out to sea, high pressure could easily fill in overhead resulting in a drier outcome for early next week.

There does seem to be better agreement towards the middle of next week, albeit a ways out, for more widespread precipitation in the region. Went with NBM PoPs here as ensembles seem to display similar QPF fields and pressure locations at this time.

Temperatures for the week start below normal, but will climb through early next week, with temps pushing into the mid 60s to around 70 by Tuesday.

AVIATION /06Z THURSDAY THROUGH MONDAY/
Short Term...VFR returns today, tonight and Thursday although there will be cigs of 3500 to 5000 ft. Winds will be light and that may portend to early morning fog today and also during the night tonight.

Long Term...VFR seems most likely, but clouds will likely be in the region throughout the period. Thus, could see periods of MVFR cigs at times as well. Vis restrictions do not appear likely, however will keep an eye out for overnight fog development...mainly in valley locations.

MARINE
Short Term...Winds/seas remain below SCA thresholds today through Thursday.

Long Term...Current trends keep major pressure systems outside of the region through early next week. Offshore low pressure may contribute to increased wave action this weekend, but there is uncertainty how close the low may pass to the coast which would influence heights. Wind gusts remain below 25 kt, out of the NE through the weekend.

TIDES/COASTAL FLOODING
High astronomical tides combined with around 0.5 feet of storm surge may push water levels to around minor flood stage around the time of high tide tonight. A Coastal Flood Advisory may be necessary but any impacts will be very minor.

GYX WATCHES/WARNINGS/ADVISORIES
ME...None.
NH...None.
MARINE...None.
