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 THE NORTHEAST/APPALACHIANS/MID-ATLANTIC STATES SUMMARY Scattered severe thunderstorms capable of damaging wind gusts and some hail are expected across the Upper Ohio River Valley and Northeast/Mid-Atlantic States during the afternoon and evening. Upper Ohio Valley to New England A shortwave trough will steadily amplify over the Great Lakes with a moderately strong belt of southwesterly mid-level flow across the region. Near/ahead of the eastward-moving cold front, increasing thunderstorm development is expected into the afternoon, increasing in both coverage and intensity. Ample mid-level height falls and around 40 kt of front-parallel effective shear could support a few initial/semi-discrete supercells prior to more prevalent upscale-growing linear modes, with the primary concern being damaging wind gusts. A brief tornado and/or hail could also occur given the relative strength of the wind profiles. Mid-Atlantic to southern Appalachians/Carolinas Widely scattered thunderstorms are expected ahead of the cold front during the afternoon, generally focusing on a pre-frontal trough as well as high terrain/Blue Ridge vicinity, with some additional sea breeze augmentations across the Carolinas/coastal plain. From roughly southern/eastern Virginia southward, upper 60s to lower 70s F dewpoints and diurnally steepening low-level lapse rates will yield a corridor of strong surface-based buoyancy ahead of storm development. Despite weaker deep-layer shear and limited midlevel height falls with southward extent, the strongly unstable air mass will favor eastward-moving thunderstorm clusters capable of producing damaging wind gusts. Somewhat stronger mid-level westerlies will reside over the Mid-Atlantic region, contributing to 30-40 kt of effective shear amid moderate surface-based buoyancy. This environment will support several organized clusters capable of scattered damaging wind gusts, and some locally higher concentrations of wind damage will be possible with any longer-lived clusters that evolve. Southern High Plains Along the tail-end of a composite cold front/outflow boundary extending westward into the southern Rockies/High Plains, widely scattered thunderstorms will spread southeastward during the afternoon. Given moist easterly low-level flow and 30-40 kt of effective shear along the boundary, a couple loosely organized storms will pose a risk of locally severe gusts and hail across parts of eastern New Mexico and far west Texas. Additional storms are expected along the boundary extending eastward across northern/central Texas to the ArkLaTex, though weaker deep-layer shear should limit storm longevity/organization.
