Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1239 AM CST Tue Jan 25 2022 Valid 261200Z - 271200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms are possible across portions of central and southern Florida Wednesday. ...Synopsis... A southern-stream shortwave trough is forecast to progress through the broadly cyclonic flow in place over the CONUS, tracking from its early period position over the NM/AZ border eastward across the southern Plains into the Lower MS Valley. At the same time, a pair of shortwave troughs are expected to move through the northern stream. The easternmost shortwave will move through the Northeast States while the westernmost shortwave moves from the Canadian Prairie Provinces southwestward through the northern Plains, Upper Midwest, and much of Ontario. Progression of these shortwaves will help maintain broad upper troughing across the central and eastern CONUS. Farther west, an upper ridge is expected to gradually build eastward, ending the period centered along the West Coast. An expansive area of high pressure will dominate the sensible weather across much of the central and eastern CONUS. The only exception is across central and southern FL, where modest low-level moisture will support thunderstorms in the vicinity of a weak cold front. ...Central/Southern FL... Isolated thunderstorms are possible over this region as the cold front gradually shifts southward. Dewpoints ahead of the front will likely be in the low to mid 60s across central FL, with slightly higher values farther south across southern FL. Even so, instability will be modest, tempered by warm mid-level temperatures. Low-level flow will also be relatively weak, but enhanced mid-level flow will still result in moderate deep-layer vertical shear. Overall environmental conditions appear supportive of a strong storm or two, but the modest buoyancy and weak low-level flow both work against a more substantial severe risk. Heights across the region are also neutral or maybe slightly rising with any large-scale forcing for ascent negligible. These factors are expected to minimize the overall severe risk, precluding the need for any severe probabilities with this forecast. ..Mosier.. 01/25/2022
