Area forecast discussion 
National Weather Service Caribou ME 
329 PM EDT Friday Aug 29 2008 


Synopsis... 
low pressure system east of Nova Scotia is bringing cloud cover 
to much of the area today. This system will move northeastward 
this evening. A weak ridge of high pressure will dominate weather 
tonight before a cold front moves in on Saturday bringing 
showers to the area. High pressure builds back in on Sunday and 
persists through the week. 
&& 


Near term /until 6 am Saturday morning/... 
retrograding low pressure system off the Maine coast is still 
generating cloud cover and shower activity along the Maine/New 
Brunswick border. All the while...a cold front approaches from the 
west. These two weather systems will play a large part in the 
weather over Maine in the next 24 hours. Overnight...the offshore 
low pressure system will cease retrograde motion and begin to lift 
northeast and out of the area. A brief pause in shower activity 
for areas mentioned above will result. Nevertheless...residual 
cloud cover from exiting low pressure and approaching front will 
keep conditions cloudy. Temperatures are expected to remain 
elevated overnight as a result. Gmos temperatures were adjusted 
upward to account for this. Otherwise...a quiet night is in store. 
&& 


Short term /6 am Saturday morning through Saturday night/... 
a cold front approaches from west Saturday afternoon. Precipitation will 
spread across the state Saturday afternoon and evening. The front 
will leave the southeastern corner of Maine by late Saturday 
night. Precipitation will generally amount to no more than a few 
tenths of inch from this system. 
&& 


Long term /Sunday through Friday/... 
a cold upper trough digs into New Brunswick Sunday morning and 
develops into a cutoff low during Sunday. The resulting instability 
may cause some showers or an isolated thunderstorm across the far 
northern and eastern regions. High pressure rapidly builds into 
Maine during Monday and persists into late Thursday or later. GFS 
suggests a very weak front may cross into the region Thursday 
night but prefer the European model (ecmwf) solution of keeping any frontal 
boundaries north of the state through the end of the period. 
&& 


Aviation /19z Friday through Wednesday/... 
MVFR conditions prevail across all terminals in the County Warning Area this 
evening as a low pressure system off the coast begins to exit the 
area. Although a brief period VFR conditions are expected 
overnight...conditions will again become MVFR/IFR on Saturday as 
cold front approaches the area. Showers also can be expected. High 
pressure returns to the area late Sunday and persists through the 
week. VFR expected. 
&& 


Marine... 
near term: winds/seas remain well below small craft criteria. 
Visibilities can be reduced in early morning hours tomorrow. 


Short term: winds/seas continue to remain below small craft 
criteria. Visibilities can be reduced with showers associated with 
frontal passage late Saturday 
&& 


Car watches/warnings/advisories... 
ME...none. 
Marine...none.
