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 ACROSS PARTS OF THE MIDDLE ATLANTIC AND OVER MUCH OF THE GULF STATES SUMMARY Isolated to scattered severe thunderstorms are expected tonight from the Gulf Coast into parts of the Mid-Atlantic. 01z Update Middle Atlantic: Narrow corridor of yet-to-be overturned instability extends across eastern WV into the Middle Atlantic. Several short line segments have developed ahead of the primary short wave, but the leading convection over eastern MD/northern DE into NJ is the primary concern, as this activity has a bit more buoyancy to work with than the trailing convection across central PA into western WV. Strong deep-layer shear remains favorable for organized storms to spread across this region over the next few hours before ingesting cooler marine layer near the Atlantic coast. Gulf States: Expansive MCS has evolved over the lower MS Valley early this evening. This complex has developed ahead of a low-latitude upper low over south central TX that is becoming more negative tilt with time. Exit region of midlevel jet will translate along the Gulf coast overnight, and this will encourage eastward propagation through sunrise. 00z sounding from LIX exhibited strong shear, but a substantial warm layer is noted around 4-5km. This warm layer should gradually cool as the aforementioned upper low advances east tonight.
