SPC Aug 6, 2022 0730 UTC Day 3 Severe Thunderstorm Outlook

SPC 0730Z Day 3 Outlook Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0225 AM CDT Sat Aug 06 2022 Valid 081200Z - 091200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe storms appear unlikely across the CONUS on Monday. ...Discussion... A mean upper ridge will exist from the Four Corners to the Mid Atlantic, providing warm temperatures aloft and weak winds. Only 20-30 kt midlevel westerlies will exist across the Great Lakes and Northeast, the exception being ME where stronger speeds will exist well north of a front. This front will extend roughly from OK to IL to southern New England during the day, and a moist and unstable air mass will exist south of it. Although dewpoints will average in the 65-70 F range along the front, warm temperatures aloft will minimize MUCAPE, with values of only 500-1000 J/kg common. Scattered afternoon storms will be possible along the front, with locally strong gusts possible, but the severe threat appears low overall. Elsewhere, isolated, non-severe afternoon storms may occur over parts of OR within a weak surface trough, as midlevel moisture increases ahead of an upper low off the West Coast. ..Jewell.. 08/06/2022 Read more CHECK UPDATE ZOOM GRAPHIC
