Weak low pressure north of the international border will continue to move east tonight. A cold front associated with the low will cross the region overnight. Expect mainly cloudy skies this evening to give way to partial clearing late tonight as the front crosses the region. Despite the passage of the front, low temperatures tonight will not be nearly as cold as last night. Expect lows to range from the low to mid teens north and upper teens to lower 20s downeast. Tuesday is shaping up as a mainly sunny day across the region, as high pressure builds across to our north. High temperatures on Tuesday will be near seasonal. Highs will range from the low to mid 20s north and upper 20s to lower 30s downeast. Clouds will be on the increase Tuesday evening in advance of low pressure approaching from the west. Snow will begin to develop from southwest to northeast, mainly after midnight Tuesday night. However, high pressure anchored to our northeast will keep dry air in place across far northern Aroostook County, where it should remain dry through most of Tuesday night. Any snow accumulation through Tuesday night will generally be less than an inch. Low temperatures Tuesday night will range from near zero to the single digits above zero across the far north and mid to upper teens down east.

Most models now are in agreement that the sfc low from the Mid Atlc states will exit ESE well S of Nova Scotia Wed, taking whats left of steady snfl ESE of the Srn hlf of the region. Aft a relative break, models are in relative agreement that a s/wv from the Nrn br of the upper jet will apch late Wed ngt and cross the region on Thu with additional sn shwr activity to msly nrn ptns of the region. The latest 12z model solutions of the ECMWF and CANGem have lowered the fcst QPF with these sn shwrs, but enough to go with likely PoPs across the Nrn ptns for now with arnd an inch sn possible with this system, and less Cntrl and Downeast. Following this system, we xpct gradual clrg to the region Thu ngt.
