Area forecast discussion 
National Weather Service Gray ME 
237 am EDT Friday Sep 4 2015 


Synopsis... 
high pressure will build south from Canada Friday through 
Saturday and then move offshore Saturday night. This high will 
provide the region a respite in the heat and humidity at least for 
a little while. However...the heat and humidity will return Sunday 
as the high anchors off the coast. July-like weather is expected 
Monday into Wednesday. A slow-moving cold front will cross the 
area Thursday into Friday with showers and thunderstorms. 


&& 


Near term /through today/... 
high pressure will build southward into Maine and New Hampshire 
today providing the region with cooler and drier weather than what 
we experienced the last couple of days. Any early morning clouds 
and isolated showers should come to an end by 12z this morning. 
Thereafter...plenty of sunshine is expected with highs in the 70s 
along with dry dewpoint values. 


&& 


Short term /tonight through 6 PM Saturday/... 
high pressure Will Park overhead tonight and Saturday. Good 
radiational cooling conditions will be present tonight and result 
in lows in the 40s at locations that normally radiate well. This 
will also result in locally dense valley fog. Sunny skies will be 
the rule on Saturday along with temperatures around 80 at most 
locations. 


&& 


Long term /Saturday night through Thursday/... 
the models are in general agreement on the long wave pattern 
well into next week. Ridging surface and aloft will provide the 
forecast area with summertime heat and humidity through middle 
week...before a shortwave impulse drives a strong cold front 
across the region Thursday. Cooler and drier air will gradually 
filter into the area during Friday and the upcoming weekend.
