Winter Storm Update!

So this storm has changed a bit in the past 12 hours. When I first posted about this storm this morning, the radar was clear for most of the Southeast and Mid-Atlantic as the rest of Dion has cleared out to sea up near Maine and Newfoundland. What remains though is a strong Low that will make its way up the I-95 corridor tonight into tomorrow. In doing so, it will produce the areas first real snowstorm of the season.

We have already seen winter weather with Dion. I assure you though that this storm will be all snow. The atmospheric temperatures are cooled and are conducive for accumulation on the ground. What this means is that snow will not changing over to anything else and will be heavy and wet due to the temperatures near the freezing mark and extremely high humidity. (Notice that by the fog this evening).

The accumulation predictions because of these previous statements are now higher than they were this morning, but not by much. Look for 3-6 inches of snow for the immediate Metropolitan area and upwards of 6 inches in areas to the South and West of DC. So far all public schools in the area have closed down.

Here is the updated probable timeline for this storm:

Monday Night Temperatures near 31-32 the entire night extremely foggy-visibility under 1/4 mile, no precipitation  

Tuesday 6AM-9AM-Light snow showers developing in the area, accumulation light to this point, temperatures still near 31-32

Tuesday 9AM-12PM: Storm will build in intensity and accumulation. Up to 2 inches an hour. Look for highest accumulations between 10-11AM.

Tuesday 12PM-3PM: Snow will continue through the afternoon though after this time it will mostly be in snow shower form

Tuesday 3pm-Late: Snow fall will end by evening-Temperatures will fall into the teens, Wind Chills in the single digits. Please stay inside as much as possible. 

Again stay safe everyone!
