There is a Slight 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 SLIGHT RISK OF SEVERE THUNDERSTORMS FROM EAST TENNESSEE INTO THE MID ATLANTIC REGION AND CAROLINAS...AND OVER EASTERN COLORADO SUMMARY Thunderstorms capable of severe wind gusts and a tornado threat are expected today from parts of the Mid-Atlantic southward into the Carolinas. A few severe wind gusts and hail may also occur this afternoon and evening across parts of the central High Plains. East TN into central VA/NC Late morning thunderstorms persist over parts of this region, with pockets of precip and clouds. This will somewhat limit afternoon heating across NC, but upstream heating and ample moisture should spread eastward. This will aid in the re-development of intense thunderstorms later today across the mountains of east TN/KY into southwest VA and western NC. Forecast soundings show considerable low and deep layer shear, favorable for supercell and bowing structures. Damaging winds are the main concern, but hail and a few tornadoes are also possible if supercells are maintained. These storms will spread southeastward into central NC during the evening with a continued damaging wind risk. Central VA into parts of PA/DE/NJ Persistent cloud cover is limiting daytime heating so far from eastern PA eastward to the coast. However, visible satellite imagery shows some clearing developing from central PA into central VA, where temperatures are climbing rapidly into the 80s. This trend will likely spread eastward and aid in the development of scattered afternoon storms. Relatively steep mid-level lapse rates and sufficient winds aloft will promote damaging winds in the strongest cores. Occasional supercell structures could also result in a tornado or two and/or hail. Eastern CO An upper ridge is centered over northern NM, with 20-30 knot westerly flow over northern CO/southern WY. Scattered thunderstorms are expected to form over the mountains and foothills today, spreading eastward into the plains by late afternoon. Ample moisture and moderate CAPE over the mountains, along with sufficient vertical shear, may support hail in the strongest cells. As the activity moves eastward into a hot air mass, locally damaging winds will become a risk. This activity may spread into western NE/KS this evening before weakening.
