SPC Jan 6, 2022 0700 UTC Day 2 Convective Outlook

SPC 0700Z Day 2 Outlook Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1130 PM CST Wed Jan 05 2022 Valid 071200Z - 081200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Only isolated, weak thunderstorms will be possible over parts of southern Florida on Friday. ...Synopsis and Discussion... A substantial upper trough is forecast to be over the Mid Atlantic on Friday, and will move quickly into the Northeast. To the west, zonal flow will temporarily develop over the Plains as a weaker upper trough moves across the Great Basin. At the surface, a high over the MS Valley will shift east through the period, resulting in stable conditions. However, it appears that a cold front may remain over far southern FL during the day, where weak instability will remain. Forecast soundings depict deep, low-level easterlies with PWAT between 1.50-1.75". As such, daytime heating may lead to isolated thunderstorms around the Miami area where low-level convergence will be maximized. Both weak shear and instability will preclude severe potential there. Elsewhere, 60s F dewpoints will reach the middle and upper TX Coasts by 12Z Saturday as southeasterly surface winds increase in advance of the western trough. While a few thunderstorms may occur over the western Gulf of Mexico late Saturday morning, the probability of thunderstorms over land is currently low. ..Jewell.. 01/06/2022 Read more LIVE: spc.noaa.gov
