DISCUSSION

KEY MESSAGE 1... 1) Cool temperatures are expected through the weekend.

KEY MESSAGE 1 DESCRIPTION... The region is under NW flow aloft through Friday, being located on the backside of a closed low, along with its surface low reflection, that is slowly moving east through the southern Maritimes. Shortwaves passing by from time to time, will bring mainly isolated showers to the region into Friday. The models, and their ensembles, continue to trend westward with the next closed low. with it now progged to be west of Montreal at 00z Saturday. As a result, have limited pops on Friday to slight chance, during late afternoon, and restricted to over portions of N Somerset and far W Piscataquis Counties. Highs today should be around 10-15 degrees below normal and highs on Friday around 10 degrees below normal. Cloud cover should preclude any frost Thursday night.

Chc-low likely pops possible over the far western zones as low pressure dives into New England. Sfc ridge axis will keep dry air over most of the CWA Friday night through Saturday morning, limiting measurable precip to south and west of Bangor. Min temps Fri night may be cold enough to produce patchy frost in areas with some clearing though most places should remain cloudy. Highs on Saturday will run 8-12 degrees below normal with maxes mainly in the 50s by afternoon. Another potential for patchy frost exists Saturday night with highs on Sunday still remaining blo normal. A prolonged period of below normal temps through the day on Tuesday before temps begin to moderate by mid-week.
