Area Forecast Discussion National Weather Service Gray ME 357 AM EDT Sun Apr 5 2020

SYNOPSIS. A cold front will approach from the west late today with some scattered showers but not everyone will get wet. Fair weather returns Monday and Tuesday with warming temperatures. Wet weather and perhaps even some wintry weather may reenter the picture mid to late week as several low pressure systems have the potential to affect northern New England.

NEAR TERM /TODAY/. This morning, ridging overhead noses in from the southwest with weak high pressure at the surface, keeping things quiet for the time being. A blanket of stratus clouds cover most of New England except for just southwest of the Whites where some patchy fog has developed. Today, a northern stream shortwave rotates through the Hudson Bay region, pushing a cold front across eastern NOAM.

Ahead of the cold front, clouds will tend to increase amid increasing southerly flow. Temperatures rise into the mid- to upper-50s over interior southern New Hampshire, and into the 40s to near 50 over western Maine where strengthening flow off the Gulf of Maine will limit warming. Scattered light rain showers arrive from the west during the afternoon and cross, with the cold front, during the evening into tonight.

SHORT TERM /TONIGHT THROUGH MONDAY/. Tonight, high over the Great Lakes pushes eastward into our area behind the departing cold front. Remaining showers will switch to snow for a brief time before drying entirely with a few tenths of accumulation possible over peaks. A few upslope clouds will linger into mid-day but overall skies should clear out. The main story on Monday will be the temperatures and dew points with a deep mixing layer forecast to develop under mostly sunny skies.

Current progs take mixing to around 700-750 mb during the day. Took these temperatures, mixed them to the surface, blended with some MOS guidance, and added a degree or so across the board and ended up with high temperatures in the 50s again, into the mid- 60s over southern interior NH. Dew points mix down to around 20-30. A seabreeze is unlikely to occur with breezy northwest winds around 10 kts, but some uncertainty remains. Some convergence along the MidCoast might help cooler air come ashore during the afternoon. Overall, it will be a very nice day which should help dry us out some.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/. Fair weather expected Monday night and Tuesday as the region remains in a broad cyclonic flow regime. A low pressure system is expected to move southeastward from the Great Lakes states Tuesday night and Wednesday bringing a relatively brief shot of precipitation to our region. Still plenty of disagreement in the 00z model suite as to the degree of amplification of the short wave trough which will have a fairly large bearing on our sensible weather Tuesday night and Wednesday. Right now will compromise and place highest PoPs across southern zones late Tuesday night and Wednesday. Some wet snow will be possible at higher elevations Wednesday morning.

Thereafter, the pattern remains quite active with the potential for several high-amplitude short wave trough to affect our region through early next week. The first of which is likely on Thursday with mainly rain, but some interior mixed precipitation possible. After that another system could affect the region late in the weekend or Monday. We'll have to keep an eye on the rivers and streams if we get several shots of rainfall over the course of the next 7 days.

AVIATION /07Z SUNDAY THROUGH THURSDAY/. Short Term /Through Monday/ . VFR prevails with light and variable winds this morning except for at LEB where a break in widespread stratus clouds have allowed patchy fog and mist to develop. South winds today turn southwesterly ahead of a crossing cold front. Scattered rain showers area accompanying the front this evening with at least patchy MVFR expected. Late tonight behind the front guidance suggests ceilings come down to MVFR before scattering out by morning. VFR under northwest flow on Tuesday.

Long Term . Mainly VFR conditions Monday night through Tuesday. Lower conditions possible late Tuesday night and Wednesday in lower ceilings and rain, particularly across southern NH and southernmost ME. Another system may affect the region Thursday and has the potential for heavier rainfall and widespread IFR conditions along with the potential for LLWS.

MARINE. Short Term . SCAs over the waters persist through today. The downward trend starts in the north, with improvement expected off the Mid Coast of Maine by the evening and elsewhere tomorrow. A cold front crosses the waters this evening with a few light rain showers possible. High pressure rules for Monday with offshore winds gusting to around 15-20 kts.

Long Term . Light northwesterly flow and calm seas for the start of the week. Thursday will see increasing southerly flow ahead of a cold front passing Thursday night with SCA likely through Friday.

TIDES/COASTAL FLOODING. Astronomical tides will peak late this week. With an active storm track expected for the next seven days we cannot rule out some coastal flood issues late next week as tides max out above 11.5 ft at Portland.

EQUIPMENT. The last GYX upper air observation was March 25 at 12Z. Unfortunately, a disruption in gas supply has temporarily halted observations from GYX. The order has been placed but a date of delivery remains TBD.

GYX WATCHES/WARNINGS/ADVISORIES. ME . None. NH . None. MARINE . Small Craft Advisory until 8 AM EDT Monday for ANZ152-154. Small Craft Advisory until 5 PM EDT this afternoon for ANZ150.
