Our next Arctic cold front lies in wait across Ontario this morning, which means we’ll start to see the telltale high clouds spreading across the region today. The developing overcast will inhibit solar heating, and with current temps near record lows for this time of year, another chilly day can be expected today. Highs will range from the low 20’s in the north to the mid 30’s in southern NH.
One neat thing that may happen today is ocean effect snow. The airmass that has spread across the East Coast is so cold that as it retreats ahead of the next front, its passage over the warm Gulf of Maine waters will create enough instability for ocean effect snow showers. The best chance for some flakes this afternoon will be northeast of Portland, and no accumulation is expected. Otherwise, the next chance for precip will arrive tomorrow evening in the form of snow squalls.
