Messy Evening Commute

Just in case you forgot, we have not reached 32 degrees for over 180 hours now, dating back to last Sunday! Although I am sure that most of you already knew that it has been damn cold. Well, that cold air is about to finally retreat back into Canada. But not before we get a poorly timed few inches of snow.

One look at the current surface temps in the US will show you the large divide between the cold air and the warm air. The surge of warm, moist air has overtaken much of the Midwest and is heading our way.

Some of that warm air will begin to leak into New England today. Remember, warm air is lighter than cold air. And this cold air we've had for 8 days really doesn't want to leave quietly! So that surge of warm air will ride over the surface cold air and creates this.

All of the leading precipitation is snow, which will be ours to deal with sometime after 4PM. Bad timing. We aren't talking about a blockbuster storm here, generally 1-3 inches for most. But we all know that any snowfall that starts at the same time as the commute does creates big time problems. Expect a slow go of it tonight.

Notice the pink color on the image above. That denotes mixed precipitation. Eventually, the warm air will intrude at all levels of the atmosphere, including the surface. So we should all change to a sleet/freezing rain mix after midnight tonight and early tomorrow morning. Any untreated surfaces tomorrow might be a bit slippery.

Tomorrow is a transition day but we really tap into the warm surge of air on Wednesday. Highs around the area will be in the mid to upper 50's!
