Previous discussion: A deep and cold upper low over northern Maine at 12Z this morning will pull east of Nova Scotia this evening. Another upper low in Quebec will move toward the region tonight. Arctic air has spilled into the area early this morning, and temperatures today will feel more like January with highs in the teens north to the low 20s along the coast. A gusty northwest wind will add to the chill. Weak disturbances may touch off some light snow showers and flurries, mainly across the northern and eastern zones. It will likely be mainly cloudy in the north and p/sunny Downeast. Tonight will be cold with lows mainly in the single digits with teens along the immediate coast. If the clouds break and the wind can go light late at night a few valleys could even drop a little below zero.
