Area Forecast Discussion National Weather Service Gray ME 1018 AM EDT Tue Mar 31 2020

SYNOPSIS. Upper level low pressure remains over the area through Tuesday. This will keep clouds and cool temperatures in the forecast along with periods of showers. A large maritime low will allow for showery periods during the late to mid week period. Drier conditions arrive late in the week and over the weekend.

NEAR TERM /UNTIL 6 PM THIS EVENING/. 1010 AM . Minor update to adjust sky grids as many areas are experiencing partly to mostly sunny skies, especially in the north. Rest of the forcast remains on track.

630AM UPDATE . The last of this morning's light snow is still rotating southwest and dissipating. Current forecast handles this well. Made only minor adjustments to hourly temperature forecast based on latest observations.

ORIGINAL DISCUSSION . Early this morning rounds of snow showers continue to rotate through western Maine and into New Hampshire as an area of upper level low pressure stalls and reorganizes just offshore. We expect the primary area of showers to push southeast and dissipate this morning with most of the day being dry for our area. Temperatures top out in the 40s with some breaks in the clouds as the day goes on.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/. It will be a similar story tonight and Wednesday as the upper low continues to wiggle around over New England. Expect cool conditions with areas of clouds. For the most part we expect shower activity to hold off until late Wednesday at the earliest as another spoke of energy rotates in from the northeast. Temperatures will be in the 40s during the day and drop into the 20s at night.

LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/. 00Z deterministic and ensemble models remain in relatively good agreement tonight forming a large scale, maritime storm over the open Atlantic east, southeast of Cape Cod Wednesday night and Thursday. Scattered rain and snow showers will retrograde back into the region from the Canadian Maritimes Wednesday night, before a period of steady rain crosses the region by Thursday. This is a complex situation with very little upper air data available over the open Atlantic. Small changes in the upper air features makes for a relatively low confidence forecast as we head through the week. In any case, this will remain a highly anomolous and blocked pattern this week with the majority of impacts along and near the coastline.

Gradient and mixing profiles suggest that highest wind gusts will be along and near the coastline Thursday and Friday. Wind gusts over 30 mph possible during those periods.

Somewhat drier and cooler air will enter the region on north, northeasterly low level winds on Friday and Saturday. This will allow for a gradual clearing over the region. By Sunday, this ocean storm will gradually shift east, allowing for weak impulses of energy to move in from the west late in the weekend and early next week.

AVIATION /14Z TUESDAY THROUGH SATURDAY/. Short Term . Should see improving conditions today with VFR possible. Light winds expected.

Long Term . Precipitation backs in from the east due to a retrograding storm out over the open Atlantic. Expect lowering ceilings and visibilities into the MVFR range during the midweek period in light rain and snow showers. Locally IFR conditions on Thursday as a period of mostly rain passes through the region.

MARINE. Short Term . As surface low pressure continues to move away, expect wind speeds to decrease as the day goes on today. However, wave heights will likely stay at or above 5 FT on the outer waters through tonight.

Long Term . A large and intense maritimes storm will be situated off the Mid Atlantic coast through the end of the work week. This system will track in a loop well east of Cape Cod late during the week, retrograding westward for a period while it does so. This will allow for building seas along our shoreline, gradually becoming a long period swell as we head into Saturday as the storm exits out over the open Atlantic.

TIDES/COASTAL FLOODING. Tides remain astronomically low early this week, but gradually increase in magnitude by late in the week and over the weekend. A large, intense and retrograding storm over the open Atlantic will allow for a building swell by late in the week and early in the weekend as the storm exits out to sea. Therefore, some splash-over is possible as we head into Friday and Saturday.

EQUIPMENT. The last GYX upper air observation was March 25 at 12Z. Unfortunately, a disruption in gas supply has temporarily halted observations from GYX. It's unknown when supplies will be restored and upper air observations resumed. Hopefully by the end of this week.

GYX WATCHES/WARNINGS/ADVISORIES. ME . None. NH . None. MARINE . Small Craft Advisory until noon EDT today for ANZ151-153. Small Craft Advisory until 4 AM EDT Wednesday for ANZ150-152- 154.
