CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 081850Z - 081945Z
INCREASING ASCENT AHEAD OF AN UPPER SHORTWAVE TROUGH HAS LED TO A
BROKEN LINE OF TCU/CB ACROSS CNTRL ND. THUNDERSTORM COVERAGE IS
EXPECTED TO INCREASE SLOWLY AS THE ENVIRONMENT OVER ERN ND CONTINUES
TO DESTABILIZE. MLCAPE VALUES AROUND 800-1200 J/KG /WITH COLD
MID-LEVEL TEMPERATURES AROUND -18 C AT 500 MB/ SHOULD BE SUFFICIENT
TO YIELD A MARGINAL THREAT FOR SEVERE HAIL...ALTHOUGH LACK OF ROBUST
VERTICAL SHEAR PROFILES SHOULD PRECLUDE A MORE ORGANIZED THREAT. A
FEW STRONG CONVECTIVE WIND GUSTS WILL ALSO BE POSSIBLE WITH SFC T-TD
SPREADS IN EXCESS OF 15 DEG F. GIVEN THE ISOLATED/MARGINAL NATURE OF
THE THREAT FOR HAIL AND STRONG WINDS...A WW WILL LIKELY NOT BE
NEEDED...BUT CONVECTIVE TRENDS WILL CONTINUE TO BE MONITORED.
