SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0151 AM CST Wed Mar 03 2021 Valid 051200Z - 061200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected on Friday. ...Synopsis... An upper low over the southern Plains will develop eastward as an open wave across the southeastern states. At the surface, a weak low near the OK/north TX border will weaken as it develops southeast. Gulf return flow will remain limited to the TX coastal Plain and portions of the Sabine Valley. However, low level moisture will remain shallow, with low 60s dewpoints hugging the coast while upper 40s to 50s dewpoints extend further north. Steepening midlevel lapse rates will help contribute to less than 500 J/kg MLCAPE. Stronger forcing will remain displaced to the north/northeast of low-level moist axis, but moderate shear and weak elevated instability should allow for isolated thunderstorms ahead of a surface cold front. Severe storms are not expected. ..Leitman.. 03/03/2021
