Area Forecast Discussion
National Weather Service Gray ME
651 AM EDT Wed May 20 2026

.WHAT HAS CHANGED...
Lowered low temperatures for Thursday night and mentioned frost
away from the coast.

&&

.KEY MESSAGES...
1. Temperatures again rise into the mid 80s to around 90 for 
much of the coast and areas downwind of the mountains, but 
highs are not expected to be as hot as Tuesday. A cold front
moves through during the day with the potential for a few gusty
showers or thunderstorms.

2. Potential for frost Thursday night away from the coast.

3. The second-half of the week will feature cooler temperatures
and drier conditions. This weekend looks to stay mostly dry with
more unsettled weather potentially incoming for early next week.

&&

.DISCUSSION...
KEY MESSAGE 1 DESCRIPTION...

A cold front will move across the forecast area today. However
timing will not be optimal for widespread strong to severe
thunderstorms. Nevertheless, given high temperatures well into 
the 80s to near 90 on the coastal plain and across southern NH 
(with attendant steep low level lapse rates), a few strong wind 
gusts with isolated storms will be possible. Gradient winds will
also be gusty, with gusts outside of any showers and storms 25 
to 30 MPH. Timing of any convective activity will be late 
morning through early-mid afternoon for most zones.

A much cooler air mass arrives for tonight and Thursday with dry
weather expected.

KEY MESSAGE 2 DESCRIPTION...

Lowered min temperatures closer to MET/MAV consensus for
Thursday night with dry high pressure moving overhead. This
should set up an ideal night for radiational cooling with frost
advisories likely needed for many interior zones away from the 
coast.

KEY MESSAGE 3 DESCRIPTION...

High pressure moves in from the west, bringing cooler and drier 
conditions. This high pressure will keep more active weather to the 
south and west of the region. Over the weekend, a low may move into 
the area and bring meaningful rain to the area. However, high 
pressure does look to be strong enough to keep any precipitation out 
of the area until early next week. High pressure starts to slide to 
the southeast by Sunday and into Monday, with some showery weather 
possible early next week. High temperatures over the weekend will 
generally be in the 60s with lows in the lower 40s.

.AVIATION /12Z WEDNESDAY THROUGH SUNDAY/...
Through 12z Friday... Westerly gusts increase this morning, 
peaking in the afternoon around 25 to 30 KT. Brief MVFR 
conditions in isold to widely sct SHRA/TSRA possible through 
early to mid afternoon. VFR tonight through Thursday night.

Outlook...

Friday: VFR.

Saturday and Saturday night: Increasing RA chances SW to NE, 
there remains uncertainty on exact timing. MVFR to IFR cigs may 
result.

Sunday and Monday: MVFR possible with showers.

&&

.MARINE...
Gusty westerly winds around 25 kt nearshore today is the
reasoning for a SCA for today. Offshore winds will be lesser.

Strong high pressure then moves over the region for late week, 
resulting in mainly conditions below SCA over the waters. Seas 
of 2-4ft and light, variable winds are expected over the 
weekend and to start next week.

&&

.GYX WATCHES/WARNINGS/ADVISORIES...

NH...None.

     152.
