Area Forecast Discussion National Weather Service Gray ME 411 AM EDT Fri Apr 3 2020

SYNOPSIS. A large, oceanic low positioned south of Nova Scotia this morning will move southward away from the area through tonight bringing very gradual improvement to the rainy, windy, raw conditions currently observed. High pressure then builds in for the weekend. For the most part, the weather pattern will be conducive to dry weather through midweek.

NEAR TERM /TODAY/. Today continues the recent trend of rainy, windy, raw conditions as a large, stacked storm over the open Atlantic churns east of Cape Cod and south of Nova Scotia. As of 330 AM, RAP13 analysis showed the low at 980 mb. A strong northeasterly low jet over the Gulf of Maine, on the north side of the low will continue to produce widespread wind gusts on the order 20-30 kts through the day. Winds maximize along exposed coastal areas later this morning . though falling just short of advisory- level winds, do still expect wind gusts along the coast to top out 35-40 kts with strongest gusts over the east- facing New Hampshire Seacoast.

Early this morning, a broad area of moderate rainfall associated with a wave rotating around the low blanketed most of the area . this will continue to rotate westward into New Hampshire, focusing in the Whites. Behind this wave dry advection from the north and weaker forcing will allow steady rain to turn more showery, gradually losing coverage and intensity from north to south. By the end of the day showers will be relegated to southern NH and extreme southwest ME.

Quite dry air quickly filters in aloft today, clearing out most upper level clouds, however low stratus cloud cover will hold temperatures in the 40s today. The exception is over the Connecticut River Valley where some afternoon clearing may allow temperatures to reach up around 50 degrees.

SHORT TERM /TONIGHT THROUGH SATURDAY/. Conditions will continue to gradually improve tonight with drier air filtering in from the north, behind the departing and weakening oceanic low. Breezy conditions will continue, except for in sheltered valleys where an abundance of lingering low level moisture may allow fog to develop. High pressure builds in from the northwest on Saturday, helping to break up some of the clouds, and allowing afternoon temperatures to warm an extra couple degrees, into the upper-40s to near 50 over most of the area.

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/. High pressure remains over the region Saturday night. A weak cold front crosses the region Sunday into Sunday night bringing low chances for showers, mainly in the mountains. High pressure builds in for Monday and Tuesday. Thereafter, large divergence in model solutions for mid to late week with low confidence in the forecast. Will keep PoPs conservative midweek, and then gradually ramp up late week. Low confidence.

AVIATION /07Z FRIDAY THROUGH TUESDAY/. Short Term /Through Saturday/ . Widespread MVFR with areas of IFR in -RA persists this morning accompanying northeast winds of 15-20 kts, gusting to around 30 kts. A low level jet just off shore peaks later this morning with gusts up to 35-40 kts possible along the coast, especially at PSM. Winds at HIE and LEB remain below 20 kts in their more sheltered locations. Although rain will gradually come to end today, from north to south, MVFR ceilings will linger at most sites through tonight under decreasing NE flow. High pressure building tomorrow will allow ceilings to lift and scatter with a return to VFR expected.

Long Term . Mainly VFR conditions expected Saturday night through early in the week as the region remains in an area of high pressure. Pockets of MVFR possible Sunday in association with weak cold front.

MARINE. Short Term /Through Saturday/ . A large oceanic low will finally pull away to the SSE through tonight with a long, slow downward trend in seas and swells following its peak around mid- day today. Gale Warnings are posted for all zones accept for Casco bay where strong SCA conditions are expected . conditions will back down below Gales tonight. Regarding seas, wave action peaks later this morning with near-shore waves 5-12 ft to as high as 18 ft over the waters. Due to the size and residence of the ocean storm, seas will be slow to come down with SCAs lingering into tomorrow at Penobscot Bay, into early Sunday at Casco Bay, and perhaps into Sunday night over the waters.

Long Term . Hazardous seas will gradually diminish by Sunday night, with sub-sca conditions expected for early next week.

TIDES/COASTAL FLOODING.

Astronomical tides will trend up until reaching their monthly peak next week. Meanwhile, a powerful storm off of Cape Cod will finally pull south and away out to sea through tonight. The long residence of the storm over the Atlantic along with a brief retrograde early this morning/last night has lead to strong seas and storm surge focused along southern coastal areas where easterly fetch is maximized and east-facing shoreline is most vulnerable.

At 08Z this morning, analysis from the Portland tide gauge reflected about 2.4 ft of storm surge. Based on observed trends, expect surge to peak around 09-10Z this morning at 2.5-2.7 ft at Portland and points south (higher surge south). When combined with a peak tide at 11Z and near- shore waves up to 12 ft, expect coastal flooding and erosion along the New Hampshire seacoast this morning. The threat generally decreases heading north into Maine where northeasterly winds are less conducive to wave action, but even along the Mid Coast some splash-over issues are possible due to surge and ESErly swells. In addition to the Coastal Flood Warning in place for coastal Rockingham Co NH and advisories for coastal Cumberland and York Co ME, coastal flood statements have been posted for the MidCoast where some splashover and erosion is possible.

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.

GYX WATCHES/WARNINGS/ADVISORIES. ME . Coastal Flood Advisory until 9 AM EDT this morning for MEZ023- 024. NH . Coastal Flood Warning until 9 AM EDT this morning for NHZ014. MARINE . Small Craft Advisory until 2 AM EDT Saturday for ANZ153. Gale Warning until 6 AM EDT Saturday for ANZ150-152-154. Gale Warning until 8 PM EDT this evening for ANZ151.
