Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
0210 AM CST Sat Feb 27 2021

Valid 011200Z - 021200Z


Severe thunderstorms are not forecast on Monday.


An upper low over the southern Rockies will pivot eastward to the
southern Plains on Monday. Moderate to strong west-southwesterly
deep-layer flow will persist over the Plains toward the lower MS
Valley during this time. At the surface, high pressure will spread
eastward from the Plains to the Midwest and lower Great Lakes
vicinity. Meanwhile, a cold front will extend from the Delmarva
southwestward to northern LA and south-central TX Monday morning.
The cold front will continue to move southeastward through the
period, moving offshore the TX coast and stalling near the central
Gulf coast and northern FL by Tuesday morning. Widespread cloudiness
and ongoing showers and thunderstorms will limit destabilization.
Furthermore, poor midlevel lapse rates and a capping inversion
around 700 mb will preclude severe-thunderstorm potential.
