017 ACUS02 KWNS 301726 SWODY2 SPC AC 301725 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1225 PM CDT Wed Jul 30 2025 Valid 311200Z - 011200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE CENTRAL HIGH PLAINS AND MID-ATLANTIC... ...SUMMARY... A few strong storms capable of large hail and damaging wind gusts are possible in portions of the Colorado/Wyoming Front Range and storms capable of damaging wind gusts are possible in the Mid-Atlantic. ...Synopsis... Upper-level ridging will continue to strengthen across the central US on D2/Thursday. A belt of enhanced westerly flow moving through the trough across southeastern Canada will overspread a cold front across portions of the Mid Atlantic. The surface cold front will extend from the Mid-Atlantic back into the Southern Plains. ...Central High Plains... Afternoon thunderstorm development is expected across the high terrain in Wyoming and northern Colorado. Across this region, steep low to mid-level lapse rates and sufficient shear around 25-35 kts will support potential for a few supercells. These storms would be capable of strong to severe wind and some instances of large hail as they move out of the high terrain. ...Mid-Atlantic... Thunderstorm activity is expected to increase near and south of the surface cold front in the Mid-Atlantic on Thursday afternoon. Enhanced flow from the trough will support deep layer shear around 30-40 kts. Mode will likely be mixed with multi-cell clusters developing by the late afternoon. Deep moisture and moderate MLCAPE south of the front will support potential for strong to severe winds from wet downbursts. ..Thornton.. 07/30/2025 $$
