Area Forecast Discussion National Weather Service Gray ME 926 AM EDT Wed Sep 30 2020

SYNOPSIS. A southerly flow will maintain warm and humid conditions across the area through early afternoon. Heavy rain will continue this morning, especially across western and mountainous portions of New Hampshire. We will see cooler and less humid air behind the cold front for the remainder of the week. Unfortunately, it will remain unsettled as a broad upper trough remains parked nearby. Low pressure will move along the New England coast on Friday.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Update . Peak winds and heaviest rainfall continues to shift through Maine with a wind shift over New Hamshire and slightly drier air in that region. A fine line will shift east per latest radar imagery and out of the forecast area by noontime. Expect the highest wind gusts to be over the next couple hours before the gradient slowly begins to relax.

Made minor adjustments to the near term forecast of temperatures, dew points and winds.

Prev Disc . 7 AM Update . Little change to the forecast at this time. Winds are quite gusty with power outages continuing to rise. The winds will continue to increase ahead of the cold front this morning (see fine line on radar) especially in showers. As soon as that line passes the winds will decrease. Torrential downpours will accompany the convective cells as PWATS are around 2 inches.

515 AM Update . Have expanded the wind advisory a few zones around the current one (mainly south). Not likely everyone sees advisory criteria, but there are plenty of convective elements as seen on latest radar mosaic that will be coinciding with peak low level jet strength and this should allow strong gusts to make it to the SFC in spots. Across southern zones temperatures have remained in the upper 60s to lower 70s all night and these warmer boundary layer temps may aid in stronger gusts making it to the SFC. Otherwise, we have no other changes at this time.

Previously .

Deep layer southerly flow continues to transport very high moisture values northward into our forecast area early this morning. This is allowing for rain, heavy at times across westernmost zones. In addition, lots of heat is being transported northward allowing our temperatures to remain in the 60s and 70s all night. Locally dense fog continues along the coast but it is suspected this will improve over the next few hours as the low level jet increases.

Have not made many adjustments to our rainfall forecast today as heaviest rainfall axis will end up being over mainly western and northern New Hampshire. South and southeastward facing slopes of the Whites will pick up the most rain from this event, with a spot 3 or 4 inch amount not totally out of the question. Elsewhere, we expect a general 1 to 2 additional inches across western and northern NH and the western ME mountains. Otherwise, toward the coastal plain and southeastern NH, much less rainfall is expected with amounts generally between a half inch and an inch as the best forcing for ascent escapes to the north. A few spot higher amounts are possible under persistent heavier echoes.

As far as winds go, the southerly low level jet (about 80 knots around 850 mb) will peak over the forecast area between 12 and 15z this morning. The vast majority of these wind speeds will remain above the SFC. However, very strong wind gusts have been known to occur just ahead of the SFC front for a couple of hours with these strong LLJ setups. In addition, convective elements could bring down these strong low level winds also. Therefore will keep the wind advisory in place and continue to watch trends in case an expansion is needed.

The heaviest rainfall should be done across most of the forecast area by late morning with a period of gusty winds possible in the wake of the front early on this afternoon.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/. Fair weather tonight and Thursday, breezy at times with lows above freezing and highs around 70 at many locations.

LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/. In the long range a couple more chances for much needed rain. 500Mb trough will remain to our west and we will maintain a southwest flow aloft. Thursday night shortwave energy moving through the trough will move northeast into the region Friday morning. the chance of precipitation will increase Friday afternoon with showers and maybe a period of steady rain. The Euro is a bit more robust with this feature. The weekend looks good at this point but can't rule out an isolated shower in the mountains Saturday afternoon as the Euro has some weak shortwave energy moving northeast into the region. Monday and Tuesday is a tough call at this point as models diverge with Euro developing a vigorous surface low Monday night on the Jersey coast and moves this feature northeast spreading rain over the region Monday night and Tuesday.

AVIATION /14Z WEDNESDAY THROUGH SUNDAY/. Short Term . IFR conditions at the coast this morning with interior locations better off it terms of vis and cigs. Expect periods of heavy rain this morning with LLWS a likelihood. Improvement is foreseen this afternoon as winds shift to the west and VFR conditions take hold. VFR conditions tonight and Thursday. SFC winds may gust 30 to 40 kt between 12z and 15z this morning.

Long Term . VFR Thursday night and early Friday deteriorating to MVFR/IFR in showers Friday. VFR expected Saturday and Sunday except MVFR possible in isolated showers at HIE Saturday afternoon.

MARINE. Short Term . Gale warnings remain in effect today with wind gusts around 40 kt expected. Winds and seas diminish tonight and Thursday in the wake of the cold front.

Long Term . Seas will be 3 to 5 feet and subsiding Thursday night. Winds and seas will remain below small craft criteria through Sunday. Monday and Tuesday winds and seas might increase depending on eventual disposition of possible coastal low.

GYX WATCHES/WARNINGS/ADVISORIES. ME . Wind Advisory until noon EDT today for MEZ014-018>028-033. NH . Wind Advisory until noon EDT today for NHZ006-008>010-012>015. MARINE . Gale Warning until noon EDT today for ANZ151-153. Gale Warning until 4 PM EDT this afternoon for ANZ150-152-154.
