Significant snow storm is predicted for later tonight and tomorrow morning with a high impact for travel the Thursday morning commute.
Snow will quickly develop from west to east after Midnight tonight. However, it will start as rain from about the I-95 corridor eastward, with a transition to snow from northwest to southeast early Thursday morning. The change over to snow will likely
occur quickly in the I-95 corridor by daybreak. It will take longer though to change over to snow on Thursday near the southern New Jersey coast and Delmarva.
The earlier Winter Storm Watches have been upgraded to Winter Storm Warnings. Winter Weather Advisories have been issued for far southeastern NJ, central DE and portions of the Eastern MD Shore. See next slide for a graphical depiction.
Heavy snow, poor visibilities and dropping temperatures will make travel dangerous. Snow will fall at a rate of up to 2 inches per hour in the warned areas from about 3 AM to 10 AM Thursday from west to east, with even some thunder possible.
High impact event for travel especially for the Thursday morning commute. Temperatures are expected to quickly drop to freezing or lower late tonight and early Thursday morning from west to east for much of the region. This along with heavier
snow and initially milder road surfaces may result in snow quickly becoming packed to the road surface. Temperatures will drop into the teens Thursday night with any slushy or untreated wet surfaces freezing up.
The snow should be wet in consistency and therefore will tend to stick to trees and power lines, possibly resulting in some power outages. North to northwest winds will increase late tonight and Thursday with gusts in the 30-35 mph range.
