SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0635 PM CST Thu Jan 07 2021 Valid 080100Z - 081200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected tonight. ...01z Update... Strong upper trough is shifting east across the TN Valley and will likely progress into the southern Appalachians by sunrise. 85kt 500mb jet will translate across southern GA/northern FL tonight as primary surface low migrates toward the GA/SC coast. While an expansive band of pre-frontal convection currently extends from SC-southeast GA- northern FL, lightning is quite sparse with this activity. Even so, forecast soundings across south FL tonight suggest some threat for lightning with stronger updrafts. For these reasons, have extended 10 percent thunder probabilities south to account for a few thunderstorms along/ahead of the front. ..Darrow.. 01/08/2021
