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 IN THE UPPER OH VALLEY AND CENTRAL APPALACHIANS SUMMARY Strong to locally severe thunderstorms are possible across parts of the Upper Ohio Valley and central Appalachians this evening. 20Z Update No changes needed to the level 1-MRGL risk. Ongoing rain swath with very isolated thunder coverage should continue shifting southeastward from the northern/central Appalachians. Severe potential should be confined to its wake as the northern extent of a modest boundary-layer moisture plume reaches the Upper OH Valley by early evening. Despite latitudinal differences in guidance since 12Z with placement of redevelopment this evening, the southern envelope appears more probable given the degree of rain-cooled air to the northeast. Convection should struggle to readily deepen/intensify with such meager buoyancy. But hodograph elongation amid northwesterly speed shear within the cloud-bearing layer will favor a threat for isolated, marginal severe storms before convection wanes overnight.
