Big rains possible in the Carolinas through the weekend
While all eyes today and this weekend will be concentrated on Hawaii’s flash flood threat with the arrival of Hurricane Iselle and potentially Hurricane Julio just behind it, another big flood threat could be emerging right here in the lower 48.
The Carolinas could be in line for a healthy soaking of rainfall over the next few days as a stationary front parks over the south, and a series of low pressure centers will ride along it over the next few days.
Translation: a big, soaking rain is in store for the weekend from Roanoke, VA all the way down to Atlanta.
It won’t necessarily come all at once, but moving from west to east, look for the rains to start on Friday before soaking Charlotte, NC and Knoxville, TN on Friday evening before moving into the I-95 corridor and then further east by Saturday. More rain is likely on Sunday, particularly from Charlotte on east, before the pattern subsides somewhat by the start of Monday.
The models are showing a widespread 1.5-to-3 inch rain event from Roanoke through Charlotte and eastward from Richmond, VA to Raleigh, NC. Some of the models are indicating an area, likely in western Virginia or North Carolina, where isolated amounts of 3-to-6 inches could fall, which would likely lead to potentially significant flash flooding concerns. Areas further south look like they’ll get a little less than that, but a good inch or more is likely from Atlanta over towards Greenville-Spartanburg, SC.
There’ll be a good chance of showers and thunderstorms in the region for the next few days before the pattern appears to finally start to break up Wednesday or Thursday of next week. Until then, break out the umbrellas in the southeast.
