Concerning Wind, Rain, and a Late Season Chill 3/11-3/13/14 (Brent/Raleigh)

A Hazardous Weather Outlook for the possibility of issuing a wind advisory Wednesday has been posted by the NWS.

Tonight: Continued surface level SW flow will keep temps mild over night. We are between a high situated over the Caribbean and a low that will move over the central plains into the Ohio valley overnight. Expect this S and SW flow to bring in high and mid-level clouds overnight with scattered rain showers over western and southern NC by daybreak. Lows in the 50s.

Wednesday: Most of central and eastern NC to remain dry for the majority of the day. Temps may warm considerably given the possibility of partial sun. Expect temps to range from the upper 60s to mid 70s, with the possibility of even warmer temps where the sun breaks through for an extended period. As the low pressure moves from the Ohio valley into the mid-Atlantic, it deepens and intensifies. With this intensifying, we get squeezed between the low pressure system and the high over the Caribbean. Winds will increase dramatically. As the low exits the mid-Atlantic and New England coasts, the trailing cold front will sweep across NC. Rain and isolated thunderstorms are likely. The NW part of the State including the NW Piedmont will see the brunt of the wind. Unfortunately, most of these areas are the same ones crippled by last Friday's ice storm. Weakened trees and branches will likely fall. 

Wednesday night: The frontal winds will roar through Wednesday evening drying out any residual moisture on roadways. Black ice should not be a factor Thursday morning. Expect lows in the mid 20s. 

Thursday: Blustery! Highs in the 40s and windy.Winds will die down in the evening, followed by a cold night with lows once again in the 20s.
