SPC Mar 26, 2022 0600 UTC Day 1 Convective Outlook

SPC 1200Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1222 AM CDT Sat Mar 26 2022 Valid 261200Z - 271200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms are possible across the Middle Atlantic into southern New England. ...Middle Atlantic to Southern New England... Very cold mid-level trough is currently located over southern lower MI. This feature is forecast to shift into PA by mid day as a 100kt 500mb speed max translates across northeast TN and off the Middle Atlantic Coast. Latest model guidance suggests 12hr height falls on the order of 150-180m with sub -30C 500mb temperatures north of this strong jet. While boundary-layer moisture will be scant ahead of this feature, forecast soundings exhibit very steep lapse rates through 6km (8.5 C/km) which will likely yield a few hundred J/kg SBCAPE at peak heating. Scattered convection will likely develop ahead of the upper low, driven in large part by surface heating, by midday. Given the very cold profiles, deepest cloud depths will easily penetrate levels necessary for lightning discharge. ..Darrow/Bentley.. 03/26/2022 Read more CHECK UPDATE ZOOM GRAPHIC
