Blizzard Tonight?


I am watching the wind speeds at this hour as they continue to get stronger. This wind I think will get even stronger this evening as rapid deepening continues to occur as the low moves up from the Carolinas and gets energized by a strong piece of energy moving from the southwest. Winds are already sustained 15 to 20 MPH with gusts to 30 MPH. If these winds increase further, they could approach limits that would take down a weak tree and some branches. What I am more concerned about with the wind is the potential for blizzard conditions this evening as the strongest winds could coincide with the heavy snowfall rates.

The snow this morning as transitioned to a light mix of precipitation. If the precipitation is light, it is in the form of drizzle. This is the lull before a quick intensification of the system this evening into early Thursday Morning. Temperatures are just around or above freezing right now. Once the precipitation becomes heavy again, we lose daylight, and we see the precipitation change to snow …flash freezing will occur.

The water on the trees, surfaces, and wires will turn to ice. This will add some weight to the trees and wires. Then as we see wet snow begin to fall, this will stick very easily to the ice. The worst still looks to be from 7:00 p.m. to 2:00 a.m. The second piece of energy looks quite strong and potent at this hour. One must wonder what awaits with this joins forces.

The snowfall map from this morning remains unchanged. 10 to 16 inches total with less in the far Northwest and the far Southeast looks good at this time. This includes the snow from this morning which averaged 1.5 to 5 inches. Thunderstorms are possible with sleet and snow.
