SPC Jan 29, 2023 0700 UTC Day 2 Convective Outlook

LIVE MAP (ABOVE) ... SPC 0700Z Day 2 Outlook Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1200 AM CST Sun Jan 29 2023 Valid 301200Z - 311200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast on Monday. ...Synopsis and Discussion... Isolated thunderstorms may occur Monday across parts of the Southeast along and south of a cold front. With enhanced west- southwesterly flow aloft expected to persist across this region, this front should make only slow southeastward progress during the day. Eventually the cold front will clear the East Coast and reach much of the Gulf Coast as surface high pressure builds over the central and eastern CONUS. Weak low-level convergence along the front and a lack of large-scale ascent aloft should keep overall thunderstorm coverage low, with the best chances for isolated lightning flashes Monday morning. Elevated convection also appears possible Monday across parts of the southern Plains into the lower MS Valley. Some of this activity may occur as early as Monday morning well to the north of a surface cold front which is forecast to be located along/near the TX Coast. Low-level warm/moist advection centered near the 850 mb front should be the primary forcing mechanism, with MUCAPE expected to remain less than 500 J/kg. Other thunderstorms may occur across parts of central into south-central TX late Monday night into early Tuesday morning as a southerly low-level jet gradually strengthens. ..Gleason.. 01/29/2023 Read more CHECK UPDATE ZOOM GRAPHIC
