From the SPC:
...LOWER AND UPPER MI TODAY...
PRIOR CONVECTION AND UNFAVORABLE TRAJECTORIES HAVE REDUCED MIDLEVEL
LAPSE RATES TO THE NE OF THE SRN PLAINS. STILL...SOME CLOUD BREAKS
ARE PROBABLE ACROSS LOWER MI BY AFTERNOON...AND POTENTIALLY ACROSS
WRN UPPER MI BENEATH THE MIDLEVEL DRY SLOT. RICHER MOISTURE
/BOUNDARY LAYER DEWPOINTS IN THE UPPER 60S/ AND AFTERNOON SURFACE
TEMPERATURES AOA 80F WILL CONTRIBUTE TO MODERATE BUOYANCY /MLCAPE
1000-1500 J PER KG...WITH NAM SOUNDINGS LIKELY TOO UNSTABLE AS A
RESULT OF THE SHALLOW CONVECTIVE SCHEME/. WIND PROFILES WILL NOT BE
PARTICULARLY STRONG OVER LOWER MI...BUT ORGANIZED MULTICELLS/LINE
SEGMENTS ALONG AND AHEAD OF THE FRONT COULD PRODUCE A FEW DAMAGING
GUSTS THIS AFTERNOON. DEEP-LAYER VERTICAL SHEAR WILL BE STRONGER
OVER UPPER MI IN PROXIMITY TO THE MIDLEVEL JET...WHERE PROFILES WILL
BE SUFFICIENT FOR LOW-TOPPED SUPERCELLS. STILL...THE DEGREE OF
DESTABILIZATION IS IN QUESTION THIS FAR NW AND THE WINDOW OF
OPPORTUNITY IS NARROW...SO WILL MAINTAIN LOW DAMAGING WIND
PROBABILITIES.
A slight risk remains for severe wind this afternoon, but for the most part, today's severe weather risk has gone way down once again.
