SPC Jan 30, 2022 0830 UTC Day 3 Severe Thunderstorm Outlook

SPC 0830Z Day 3 Outlook Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0145 AM CST Sun Jan 30 2022 Valid 011200Z - 021200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected on Tuesday. ...Synopsis... An upper-level shortwave trough will weaken as it shifts east across the Gulf of Mexico on Tuesday. Southerly low-level flow will maintain modest boundary-layer moisture from east TX into the Lower MS Valley vicinity. Widespread cloud cover, areas of showers and relatively warm midlevels will limit destabilization ahead of a surface cold front forecast to shift southeast across the southern Plains and Ozarks. Any stronger forcing for ascent will remain over the Gulf, and weak vertical shear combined with a lack of stronger destabilization will preclude thunderstorm activity inland. Elsewhere, a large-scale upper trough will deepen across the western U.S., while surface low pressure develops over AZ/NM in response. Thunderstorm potential will remain low due to a mostly dry and stable boundary layer. ..Leitman.. 01/30/2022 Read more CHECK UPDATE ZOOM GRAPHIC
