SPC Jan 18, 2022 0830 UTC Day 3 Severe Thunderstorm Outlook

SPC 0830Z Day 3 Outlook Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0222 AM CST Tue Jan 18 2022 Valid 201200Z - 211200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast across the contiguous United States on Thursday. ...Synopsis and Discussion... A line of showers and thunderstorms will probably be ongoing at the start of the period Thursday morning across parts of the lower MS Valley into the Southeast along/ahead of a cold front. There is still some uncertainty with the placement of the front and precipitation over this region in various model guidance. Regardless, the low-level moisture ahead of the front is forecast to be rather limited, with minimal instability present. While isolated thunderstorms may continue through the morning as the front moves offshore, severe convection appears unlikely owing to the lack of stronger instability (MUCAPE generally less than 500 J/kg). Otherwise, low-level moisture should gradually return northward through the period across parts of south/central FL ahead of a positively tilted upper-trough encompassing much of the central/eastern CONUS. Isolated convection appears possible mainly late Thursday night across portions of coastal south FL and the Keys as this process occurs. ..Gleason.. 01/18/2022 Read more CHECK UPDATE ZOOM GRAPHIC
