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 OVER PORTIONS OF THE MID-ATLANTIC...NORTHERN NORTH DAKOTA...AND NORTHWEST/WEST TEXAS SUMMARY Scattered wind damage is possible with thunderstorms across the Mid-Atlantic this afternoon and evening. Large hail and damaging gusts may occur with thunderstorms in North Dakota and west/northwest Texas. Mid Atlantic Scattered thunderstorms are expected once again today from parts of eastern OH/WV into PA and the Mid-Atlantic region. The overall thermodynamic environment has weakened considerably compared to yesterday, with CAPE, low-level lapse rates, and heating showing parameters only marginally favorable for damaging winds. Nevertheless, parts of northern VA into eastern PA and NJ will see strong heating all day with storms moving in during the early evening. This will help to maximize low-level conditions favorable for gusty/damaging winds later today. Therefore will maintain ongoing SLGT risk area. Gulf coast states to Carolinas Hot and humid conditions will prevail over much of the southeast today, with dewpoints in the 70s and pockets of moderate CAPE. Scattered slow-moving thunderstorms will occur across this region with locally damaging winds possible in the strongest storms. TX Full sunshine is noted over TX today, with dewpoints near 70F and the potential for afternoon MLCAPE exceeding 3000 J/kg. All CAM solutions indicate thunderstorm development this afternoon along the remnant outflow from overnight convection, extending from the southern TX Panhandle into north-central TX. Initial storms may be supercellular with large hail and damaging winds possible. Storms are expected to congeal through the evening and sag southward, with a continued risk of damaging winds. Northern ND A cold front will move across northeast MT today, with a diffuse surface dryline along the MT/ND border. Widely scattered thunderstorms are expected to develop during the late afternoon. Shear profiles will be sufficient for supercell structures capable of large hail and damaging winds. A tornado or two cannot be ruled out. MT Scattered afternoon high-based thunderstorms are expected to develop over the mountains of southwest MT and spread east-northeastward. Inverted-v profiles and moderately strong winds aloft will pose a risk of damaging wind gusts in a few of these storms.
