Area Forecast Discussion National Weather Service Gray ME 1036 PM EDT Thu Apr 2 2020

SYNOPSIS. A strengthening storm over the Atlantic will meander over the Gulf of Maine through tonight, slinging moisture into our area with periods of rain over most of New England with cool and damp conditions. Rain gradually tapers down Friday with high pressure building in from the west bringing a dry weekend.

NEAR TERM /UNTIL 6 AM FRIDAY MORNING/. 1030 PM . Forecast is generally on track for the overnight. LAtest obs and web cams show some light accums of snow at lower elevations in nrn NH, but the transition to rain is occuring from E to W, as evidenced by KBML. This trend should continue overnight, with accums over an inch likely abv 2500 feet. Otherwise the precip should continue to become more intermittent and slighter thru the night, but precip will continue thru tonight, tapering off after daybreak.

7 PM . Seeing some colder drier air work down into the valleys of nrn NH, and allowing some SN to reach the ground. Probably not sticking too well, and places in the valley will likely on see a coasting in some areas, areas above 1500 feet or so may see a little more in accumulating over the next couple hours. Once the more easterly flow kicks in this should allow all but the elevations abv 2500 feet to change back to rain.

On the coastal plain and in the foothills temps are generally in the 40-45 range, and don't see too much change overnight in this area with the winds shifting a little more N-NE and actually advecting in slightly warmer and moister air from that direction. Also upped QPF in a few spots bit overall 0.75-1.25" should be good in many spots. Precip should lighten up a bit and become more intermittent, if not showery, late tonight.

Previously . At 18z a 975 millibar low was centered well offshore to the east of Cape Cod. This vertically stacked system will continue to meander back to the west early tonight before gradually sinking further south late tonight. Impulses pivoting around the upper low will generate periods of rain overnight . along with some wet snow or sleet across the higher terrain of far northern New Hampshire and the western Maine mountains where some light accumulations will be possible. It'll be a breezy night with northerly winds gusting up to 25 mph over the interior and over 30 mph along the coast. Temperatures will only drop back a few degrees tonight given cloud cover and winds.

SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/. The low will meander further south then southeast on Friday with drier air beginning to work in from the north. Shower activity will become more scattered from north to south as the day progresses. It'll be another mostly cloudy and raw day with northerly winds gusting between 25 and 35 mph along the coast and over our Maine zones . and gusting between 15 and 25 mph over New Hampshire. Highs should be mainly in the 40s. Friday night winds will gradually diminish as the low continues to retreat further offshore and drier air continues to filter in from the north. It'll be a mostly cloudy night with any lingering showers over southern New Hampshire and southwest Maine ending overnight. Lows will range from near 30 across the mountains with mid and upper 30s elsewhere.

LONG TERM /SATURDAY THROUGH THURSDAY/. Upper ridging will move in from the N Sat and bring an end to the rain showers. Will keep low level NE flow and maritime conditions . so I expected with a little insolation that plenty of broken cloud cover will result.

A S/WV trof moving thru Canada will trail a weak cold front into Nrn zones. Could see a some isolated to scattered showers out of it . but expect things to remain dry especially outside of the mtns.

Otherwise the wx will be mainly quiet thru the end of next week While there remains quite a bit of model spread. a deep trof is forecast to drop into the Ern CONUS . wrapping up low pressure off the East Coast. That looks like the next best chance for widespread precip.

AVIATION /03Z FRIDAY THROUGH TUESDAY/. Short Term /Through Friday Night/ . Cigs lowering to MVFR throughout with areas of IFR. Areas of -RA with pockets of SN/PL over mtn sections. Northerly SFC winds gusting btw 20 and 30 kt through Fri afternoon before slowly diminishing.Conditions improving to MVFR throughout Fri night with sct -SHRA over Srn NH and SW ME terminal sites.

Long Term . Despite SHRA moving out we remain in cool/moist NE flow. I expected some BKN MVFR CIGs to linger thru the day Sat. Conditions continue to improve into Sun. May see some local MVFR in SHRA Sun as a front crosses the area.

MARINE. Short Term /Through Friday Night/ . An oceanic low south of Nova Scotia will retrograde back toward the Gulf of Maine, will building seas and winds into tonight. Gales continue with strong SCA for Casco Bay. We could see a few gusts approach storm force on Friday on our eastern outer waters. Winds and seas will begin to diminish Friday night with lingering Gales for the outer waters.

Long Term . SCA wind gusts are expected to diminish by Sat morning. Seas however will be slow to diminish after ocean storm finally moves out to sea. I expect hazardous seas to linger into Mon.

TIDES/COASTAL FLOODING. Astronomical tides will trend up until reaching their monthly peak next week. Meanwhile, a powerful storm off of Cape Cod will loop out to sea tonight and Fri. The duration the storm will remain offshore and the brief westward movement leads to a good period of easterly fetch producing 10+ ft swells, 12-17 ft waves, and surge exceeding 2 to 2.5 ft late tonight. Coastal flooding is expected along the Seacoast during the Fri morning tide cycle where fetch will be maximized. Flooding will become less likely the farther N you head along the coast . but significant splashover and erosion is expected. Coastal flood warning has been issued for Rockingham County . with advisories for York and Cumberland Counties. Most vulnerable will be E and NE facing exposure. Additional splashover may be possible N of Portland.

HYDROLOGY. The Swift River at Roxbury is rising and rapidly and is forecast to get close to flood toward daybreak. Some of the other ungaged rivers and streams that drain from easterly upslope in the mountains will likely see some fast rises overnight.

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 from 5 AM to 9 AM EDT Friday for MEZ023- 024. NH . Coastal Flood Warning from 5 AM to 9 AM EDT Friday 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 Friday for ANZ151.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
