Area forecast discussion 
National Weather Service Gray ME 
255 PM EDT Friday Aug 29 2008 


Synopsis... 
a weak trough will move through the region this afternoon and 
tonight causing a few widely scattered showers. Saturday a cold 
front will move off the coast by early evening sparking some 
scattered showers and possibly a thunderstorm or two. High 
pressure will build over the region Sunday through Thursday. A 
cold front will approach the area Friday. 


&& 


Near term /through tonight/...cloud cover will be the forecast 
problem tonight. We are sandwiched between two systems. Weak 
ridging through western Maine and New Hampshire has helped to keep 
the clouds to the west at Bay as well as clouds associated with 
surface low south of Nova Scotia. Believe the overall trend will be 
for clouds to increase from the west as cold front slowly 
approaches. Some showers have fired ahead of some more humid air. 
These should die out soon after sunset and remain widely 
scattered. Will forecast some patchy fog tonight as any breaks in the 
overcast will allow for cooling tonight. Used mavs as guidance for 
temperatures tonight. 




&& 


Short term /Saturday/... 
for Sat day cold front nears the forecast area late morning and 
passes offshore Sat evening. We will be unstable enough to produce 
scattered showers and a thunderstorm or two. Front will move 
offshore by early evening. 


&& 


Long term /Saturday night through Friday/... 
just a chance of lingering showers....mainly in middle coast sections 
Saturday evening then looking for clearing downwind of the 
mountains. Upper trough swinging through the region will keep 
variable clouds in the mountains. 


High pressure builds into the region from the west on Sunday. 
Expect some cloudiness to bubble up with daytime heating as upper 
slowly shifts eastward with mostly cloudy skies persisting in the 
mountains. 


Weather remains quiet through midweek as high pressure remains 
nearly stationary to the west of the region. Warmer air riding 
over ridge begins to flood into the region on Monday with 
temperatures rising to above normal levels Tuesday and Wednesday. 
Warmest locations likely to see readings in the middle to upper 80s. 


Cold front approaches the region from the west on Thursday. Pre- 
frontal trough may kick off some showers and thunderstorms in the 
afternoon but only going with slight chance probability of precipitation at this point in 
time as there will likely be some differences in timing of this 
feature in the next several days. 


Cold front prognosticated to cross the region Thursday night and push 
offshore by Friday morning followed by more high pressure. 


&& 


Aviation /18z Friday through Wednesday/... 
short term...expect mostly VFR this afternoon and early evening. 
Patchy IFR/LIFR possible after 02z in fog and stratus. For Sat any fog 
stratus lifts/Burns off resulting in VFR. Expect scattered MVFR during 
afternoon in showers and possible -tsra. 


Long term...generally VFR Saturday night through Wednesday with 
the usual morning fog in River Valley locations. 


&&

quite on the waters tonight and Saturday. Winds should come around 
to SW later tonight. 


Long term...winds and seas remain below Small Craft Advisory levels.
