As a strong cold front pushes toward the region, sustained wind speeds of 20 to 25 mph with wind gusts of 35 to 40 mph are expected this afternoon and evening. Some isolated wind gusts of 40 to 45 mph will be possible in rain showers right along the cold front late this afternoon and evening.

There is a Marginal Severe Storm Risk for your location. Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE MS/TN/OH VALLEYS INTO THE SOUTHEAST...AND ALSO ACROSS COASTAL NC SUMMARY Isolated strong to severe thunderstorms capable of producing occasional damaging winds and perhaps a tornado or two may occur through this evening across parts of the lower/mid Mississippi Valley into the Tennessee and Ohio Valleys and Southeast, and late tonight across portions of coastal North Carolina. MS/OH/TN Valleys into the Southeast The primary changes to the Marginal Risk have been to clear areas behind the low-topped convective line and cold front, and to expand northeastward somewhat based on where recent HRRR/RRFS guidance maintains a low-topped but well-defined frontal band with potential for localized strong/damaging gusts. A line of low-topped convection has developed along a cold front and is moving eastward across parts of IL and southeast MO this afternoon. Despite very weak to negligible buoyancy, very strong low-level flow/shear (with 50+ kt at 1 km AGL per regional VWPs) has supported occasional gusts of 40-55 mph and isolated wind-damage reports along this line. Forcing related to a strong mid/upper-level shortwave trough moving quickly eastward across the region will help to sustain a low-topped frontal band into this evening, which may be capable of producing sporadic strong/damaging gusts into parts of the Ohio Valley. Recent HRRR/RRFS runs suggest that gusty winds associated with the frontal band may spread across parts of the Allegheny Plateau overnight, but with essentially nil buoyancy expected in this area, confidence is currently too low to expand wind probabilities into this area. Farther south into parts of TN/MS/AL, somewhat greater (though still weak) buoyancy will be in place later this afternoon into the early evening, as 60s F dewpoints spread northward to near the TN/MS/AL border region. A broken band of storms may develop in advance of the front, with potential for at least marginal supercell structures and an attendant threat of isolated damaging wind and possibly a tornado. Any longer-lived cells may tend to merge into the eastward-moving frontal band with time, with at least an isolated severe threat spreading east across TN through the evening. Coastal NC No major changes have been made to the Marginal Risk across coastal NC. See the previous discussion below for more information. FL Panhandle vicinity Cells with occasional rotation have been noted offshore of the FL Panhandle this afternoon, though temperatures remain relatively cool with widespread cloudiness inland. There is some potential for a stronger cell or two to eventually approach the coast or develop slightly inland, but lingering near-surface stability may tend to limit the severe threat across this area.
