12AM Day 1 Convective Outlook for Saturday, August 30. NO SEVERE THUNDERSTORM AREAS FORECAST
SUMMARY
A few strong thunderstorms will be possible across parts of the southern and central Plains today, but any severe potential should remain low.
DISCUSSION
Flow at mid-levels will remain northwesterly over the top of a moist airmass today in the southern and central Plains. A weak upslope flow regime will be in place to the east of a surface trough over eastern New Mexico and the Texas Panhandle. As surface temperatures warm during the day across this airmass, scattered thunderstorms will develop. Isolated storms may form near the surface trough and instability axis, with increased convective coverage further to the east in the less unstable air. A few strong storms will be possible in areas where convection is co-located with maximized instability. However, lapse rates will be weak suggesting that the severe potential will remain low in the southern and central Plains today. Elsewhere across the continental U.S., no severe threat is expected today and tonight.
