000 ACUS01 KWNS 200042 SWODY1 SPC AC 200040 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0640 PM CST Tue Jan 19 2021 Valid 200100Z - 201200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected through tonight. ...Synopsis and Discussion... A closed upper low will continue to move generally south-southwestward tonight off the coast of southern CA and the northern Baja Peninsula. Along its eastern periphery, a couple of thunderstorms may occur through the end of the period across parts of the lower CO River Valley in an environment characterized by weak elevated instability. Farther east, the potential for isolated thunderstorms along/near a cold front across parts of TX appears to have diminished, as an inversion around 700 mb observed on the 00Z DRT sounding should prove hostile to additional convective development. ..Gleason.. 01/20/2021 $$
