630am update...The cold front is entering the NW portion of the state, will quickly stall out in central zones this morning and then retreat northward this afternoon as a warm front. No changes were made to the forecast with this update. There are a few sprinkles in northern Washington County with an upper trough passage, but these will be out of the state in the next hour. Previous discussion... The area is currently in the warm sector of a weak frontal system. The cold front will move into northern zones this morning, stall and move back north as a warm front. No precipitation is expected and there will be little cloud cover after early this morning. An upper level ridge and surface ridge will build this afternoon. Warm advection and subsidence with this ridge will overcome the very brief cold advection behind this morning`s cold front and the net effect will be that today`s highs will be warmer than the highs recorded on Tuesday. Expect mid 50s in northern Aroostook and low to mid 60s in the southern half of the forecast area. There are relatively strong northwest winds aloft that will mix down today such that gusts to 25 mph are possible. For tonight, warm advection continues with a persistent SW breeze. This will keep lows in the upper 30s to lower 40s in spite of clear skies.
