Freezing Rain Advisory

A Freezing Rain Advisory is in effect for the DC area and points west from 3AM to 9AM. Surface temperatures are forecast to be in the upper 20's to low 30's. However, temperatures just a few thousand feet up will be well above freezing due to warm air overrunning the cold air wedge over our area. This warm air overrunning will create light precipitation. This will possibly lead to light ice accretion in the order of up to a 1/10 of an inch. A 2hr delay is possible tomorrow morning but not a given. Later in the morning, the temps will rise above freezing as the warm air travels northward and reaches pushes out the cold air ahead of a consolidating low pressure system to our west.
