SPC Jan 25, 2022 0830 UTC Day 3 Severe Thunderstorm Outlook

SPC 0830Z Day 3 Outlook Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0203 AM CST Tue Jan 25 2022 Valid 271200Z - 281200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms are possible along the east-central and southeast Florida Coast Thursday. ...Synopsis... An amplified upper ridge is expected to be in place over the West Coast early Thursday, with broadly cyclonic flow downstream across much of the central and eastern CONUS. Several shortwave troughs are forecast to move within this cyclonic flow, including a shortwave expected to progress through the Southeast states and another expected to progress from the central Rockies southeastward through the southern High Plains into the southern Plains. The progression of these shortwaves will reinforce the central and eastern CONUS upper trough while the western CONUS upper ridge slides eastward and builds. As a result, by early Friday an amplified western CONUS ridge/eastern CONUS trough upper pattern will likely be in place. Dry and stable conditions will dominate the sensible weather across the majority of the CONUS. The only exception is across central and southern FL, where modest low-level moisture will likely remain in place throughout the period. Easterly/northeasterly low-level flow may help foster a few thunderstorms along the east-central/southeast FL Coast. ..Mosier.. 01/25/2022 Read more CHECK UPDATE ZOOM GRAPHIC
