Today and Tonight: Our nearly one month stretch of quiet weather will come to an abrupt end this week as our area will be in a very active weather pattern throughout this week. A frontal boundary is currently stretched just south of southern New England this morning and a high pressure system is located over Quebec province. This high pressure system will quickly track to the east today as a fast moving storm system swings across our area tonight bringing some light snow mainly after midnight tonight to northern Maine. Snow accumulations tonight will be less than one inch. High temperatures today will be near 38 Degrees. Low temperatures tonight will be near 25 Degrees.
Monday and Monday night: That storm system will quickly move to the east by early Monday and high pressure will build into the area from Quebec province during Monday. I expect sunny to partly sunny skies during throughout Monday with high temperatures near 45 Degrees. High pressure will continue to provide clear to partly cloudy skies for Monday night with low temperatures near 28 Degrees.
Tuesday through Wednesday night: Precipitation in the form of snow, sleet and rain will spread northward into northern Maine during Tuesday afternoon as low pressure tracks from the Ohio Valley eastward to near Boston by Tuesday evening. Little if any snow accumulation is expected during Tuesday afternoon as surface temperatures will be in the mid to upper 30s.
That low pressure system will track into the Gulf of Maine during Tuesday night and I expect a mix of snow and sleet across northern Maine during Tuesday night. At this time, snow and sleet accumulations Tuesday night may average around 2 inches. Low pressure will track to near Nova Scotia during Wednesday and Wednesday night and the mixed bag of wintry precipitation will continue throughout Wednesday and Wednesday night. Possible snow and sleet accumulations Wednesday may be around one inch and an additional inch or so of snow possible for Wednesday night.
Thursday through Saturday: High pressure will briefly control our weather during Thursday afternoon and Thursday evening. After that, an arctic blast will arrive on Friday and will be accompanied by snow showers and snow squalls from late Thursday night into Friday morning. The coldest air since the first of February will arrive during Friday and continue into Saturday with high temperatures at best in the low 20s and low temperatures Friday night in the single numbers. Needless to say, this will be a real shock to the system based on the recent record high temperatures in the upper 50s to near 60 Degrees.
