Today and Tonight: A cold front will push to our south this morning and clouds associated with this front will continue to dissipate this morning. High pressure located over Hudson Bay will build across the area today and tonight. I expect partly to mostly sunny skies this morning and sunny skies this afternoon. High temperatures today will be near 23 Degrees. Clear skies and light winds are expected for tonight; therefore I expect that strong radational cooling will cause our temperatures to bottom out near 5 Below Zero tonight.
Saturday through Sunday: High pressure will control our weather this weekend. The biggest bugaboo with Saturday’s forecast is how much cloud cover may be associated with a piece of energy that will track south out of Quebec province towards the Maritimes. Am going to go with partly sunny skies throughout Saturday, however, it is not out of the question that skies will be completely clear throughout the day Saturday. High temperatures Saturday will be near 20 Degrees.
For Saturday night, I expect clear to partly cloudy skies with low temperatures from Zero to 5 Below Zero. High clouds Sunday associated with warm air advection combined with thickening clouds during Sunday afternoon associated with an approaching storm system will give our area a partly sunny day. High temperatures Sunday will be near 28 Degrees.
Sunday night through Monday night: A significant storm is still forecast for Monday. I expect snow to develop across northern Maine just after midnight Sunday night and continue into early Monday morning. This snow may accumulate 1 to 3 inches or so before it changes to sleet and freezing rain for a short time Monday morning. The sleet and freezing rain will then change to all rain by mid to late morning on Monday. Temperatures Monday afternoon will quickly rise into the upper 30s with rain, heavy at times, expected. This combination of mild temperatures and rainfall will lead to a good amount of snowmelt. I expect rainfall amounts of around one inch from this storm and this, in combination with the snowmelt, could lead to street flooding and the outside possibility of small stream flooding.
The rain will end during Monday evening, however, temperatures will remain quite mild for this time of year.
Tuesday through Thursday: Cloudy skies and mild temperatures are expected on Tuesday before an arctic cold front crosses northern Maine on Tuesday night. Behind this front, some of the coldest air of this winter will invade northern Maine late next week accompanied by scattered snow shower activity. One fly in the ointment is the possibility that an upper level low pressure system tracking towards our area on Wednesday into Thursday could cause the development of a surface low pressure system over the Canadian Maritimes. The European model insists on this happening while the GFS model says no. If this low pressure system does form, then snow could back into northern Maine during Wednesday afternoon and Wednesday night. For this forecast, I am going to go with snow possible for Wednesday afternoon and Wednesday night.
