SPC Jan 28, 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 Fri Jan 28 2022 Valid 301200Z - 311200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected on Sunday. ...Synopsis... An upper low and attendant trough over the lower CO Valley Sunday morning will shift east across the southern Rockies, emerging over TX/the southern Plains by Monday morning. In response, a surface trough will develop over the central/southern High Plains and southerly low-level flow will modestly increase. Prior cold frontal intrusions, deep into the Gulf of Mexico/Caribbean vicinity, will limit boundary-layer moisture return. 50s to near 60 F surface dewpoints will mainly be confined to the lower/middle TX coast late in the forecast period. As such, thunderstorms are not expected at this time. Elsewhere, several upper shortwave troughs will migrate through larger-scale northwesterly flow from the northern Rockies toward the Atlantic coast. Dry and stable conditions with surface high pressure centered over the Midwest will preclude thunderstorm activity. ..Leitman.. 01/28/2022 Read more CHECK UPDATE ZOOM GRAPHIC
