1250 PM Update...Adjusted the pops to carry 40% across the crown of Aroostook County into mid afternoon as upper trof is moving across the region. Radar showed an area of snow moving across the crown w/obs and reports showing a band of heavy snow w/gust winds to 40+ mph. RAP soundings showed some CAPE of 35 joules w/0-3km shear of 35 kts. Definitely some convective potential w/this band. Issued a Special Weather Statement to cover this band of snow. Some areas could see a quick 1/2 to 1 inch of snow. Winds were causing some issues around the region w/reports of power outages due to tree limbs on power lines. Increased winds a bit for the afternoon w/gust potential to 45 mph. Temps are steadily falling back attm w/upper teens to lower 20s across the northern 1/2 of the CWA. Previous Discussion... High pressure will build east toward the region later tonight. Gusty winds will persist into the evening then begin to diminish overnight. However, the winds will remain strong enough to produce dangerous wind chills of 20 below zero to 30 below zero later tonight across northern portions of the forecast area. Have issued a Wind Chill Advisory for northern portions of the forecast area tonight into Saturday morning. High temperatures will occur early today ranging through the 20s to lower 30s north, with upper 30s Bangor and interior Downeast with around 40 to the lower 40s along the Downeast coast. Low temperatures tonight will range from around 5 below zero to around 10 below zero north, to around zero to 5 above zero Bangor and Downeast.
