National Weather Service Gray ME 
602 am EDT Thursday Jul 24 2014 


Synopsis... 
a cold front will move offshore this morning. High 
pressure will build in from the west Friday and Saturday. Wet 
weather is likely Sunday through Monday as an upper level trough 
drops into the region. The trough will remain over the eastern U.S 
through much of next week keeping unsettled weather across the 
area. 


&& 


Near term /through tonight/... 
update...have adjusted pop to track the last batch of showers 
through the County warning forecast area for the next couple of hours. Otherwise no major 
changes to the current forecast. 


Previous discussion...cold fnt continues to slowly edge offshore 
this morning. All that remains are mainly scattered showers at this 
hour. Cooler...but more noticeably drier...air will filter in from 
the north through daybreak. Cold air advection induced mixing should prevent any fog 
concerns this morning as well. 


High temperatures will much cooler today...with readings topping out 
below 80. 


&& 


Short term /Friday through Friday night/... 
high pressure continues to nose into the region tonight. Clear skies 
and winds becoming light and variable will promote quick cooling 
after sunset. Recent rainfall and cool temperatures should lead to a round of 
valley fog. 


High pressure remains in control Friday...with temperatures moderating upwards a 
few degrees. 


&& 


Long term /Saturday through Wednesday/... 
fair weather is 
expected Friday night and Saturday as a ridge of high pressure 
moves off the coast. Return flow on the back side of the high will 
bring warmer temperatures and higher humidity levels for the day 
Saturday and into Sunday. The approaching upper level trough will 
bring an increasing threat of showers and thunderstorms during the 
day Sunday...Sunday night...and Monday as surface low pressure 
moves northeast along an approaching frontal boundary. Greatest 
chances of thunderstorms will be during the afternoon hours. 


Upper trough remains draped across the eastern U.S. For much of 
next week keeping the cool and unsettled weather pattern in place 


&& 


Aviation /10z Thursday through Monday/... 
short term...ceilings continue to improve this morning...with a few 
areas of MVFR left and very isolated patches of IFR or lower. That 
will continue to be the trend through daybreak. Expect VFR conditions 
to prevail today through Friday. Exception to that rule will be 
tonight...where high pressure building in may promote valley fog with 
cool temperatures and recent rainfall. 


Long term...VFR conditions expected Friday night through Sunday 
morning with some IFR conditions possible in valley fog early Saturday 
and Sunday mornings. Occasional MVFR conditions expected Sunday 
through Monday in showers and thunderstorms with IFR conditions 
possible in daytime thunderstorms and overnight patchy fog.

Small Craft Advisory is cancelled. Winds and seas will remain below Small Craft Advisory levels through 
Friday. 


Long term...showers and thunderstorms expected Sunday through 
Monday...then a chance of showers or thunderstorms through middle
