Much Needed Rain on the Way!

9:30 Pm Tuesday 2/22/2011 Updated:

Much cooler air will continue to filter into the area tonight as a back door cold front works its way down the east side of the Appalachian Mountains. We had dramatic temperature differences across the Carolinas today. At one point I looked and saw current temperatures of 39 in Raleigh, 35 in Norfolk Virginia and 51 in Wilmington, 66 in Charlotte. That is a huge contrast in temperatures. Colder temperatures will over take the rest of the Carolinas tonight. This will set up a wedge along the blue ridge that will potentially save much of the western Carolinas from the threat of severe thunderstorms and tornadoes but not heavy rain. This will be the first significant rainfall in over a month. We need it!

Wednesday Afternoon - Thursday Afternoon Map:


A strong low Pressure system will track from Oklahoma to Kentucky bringing snow along and north of the Ohio River and the threat of severe thunderstorms and tornadoes from eastern Oklahoma to Tennessee and Kentucky. This will be the first MAJOR severe weather outbreak of the season with large, violent, long tracked tornadoes capable of doing localized catastrophic damage. This is just the beginning of what will be a very active tornado season in the nations heartland.

Thursday - Friday Morning Map:



By Thursday afternoon the low pressure system should be advancing through the Ohio Valley and move offshore near New Jersey overnight. The severe threat should diminish significantly as the storm moves east into the cool wedge that has developed along the east side of the Appalachians. Still, a slight chance of severe thunderstorms is likely along and south of I-85 from Alabama to the Carolina Piedmont. Heavy, soaking rains will be common south of the track of the low pressure with heavy snows in interior New England.
