A little spring in December? I’ll take it. Today’s 60s will be short-lived, but there’s no massive cool-down on the near horizon (although there may be one just beyond that). And while we cool it down about 15 degrees tomorrow, that’s still near or above normal as we approach the coldest average temperatures of the year.

Through Tonight: Skies trend mostly clear after the clouds from today’s cold front finish moving off to the east. Behind the front, winds stay up around 5 to 10 mph from the northwest through the night. And while a cold front passes, it won’t be particularly cold overnight as lows reach the mid-30s to near 40.

Tomorrow (Wednesday): We wake up to skies that are partly to mostly clear and spend the day largely under similar conditions. Those winds from the northwest around 5 to 10 mph persist, although they may swing more toward the south by late day. Clouds may begin to increase again then, as well. Temperatures are down a good bit from today, but highs near 50 are still warmer than normal.

Next storm: Although Wednesday is dry, we have precipitation entering the area late tomorrow night into Thursday morning. Temperatures will be borderline cold enough to support some wintry mix (sleet or freezing rain) as it does so.

As the NAM model simulation above shows, temperatures will be near and below freezing, especially north of the city, as precipitation moves toward the area before dawn Thursday. However, given preceding mild conditions, and the fact that the bulk of the precipitation may not make it in until around sunrise, it seems the risk of freezing rain is fairly minor.

It is worth considering that some slick spots may be possible, particularly north of the city, early Thursday morning. We’ll have more as needed. And do expect a damp Thursday as this storm wraps up and delivers a snow risk to New England.
