VALID 251200Z - 261200Z
...SYNOPSIS...
A SHORT WAVE TROUGH WILL PROGRESS E/NEWD ACROSS S-CNTRL CANADA.
TRAILING PORTION OF ATTENDANT SURFACE COLD FRONT SHOULD PUSH
GRADUALLY EWD ACROSS THE UPPER MS VALLEY...BECOMING QUASI-STATIONARY
INVOF THE SD/NEB BORDER. CONSENSUS OF GUIDANCE SUGGESTS
DESTABILIZATION AHEAD OF THE FRONT MAY BE TEMPERED BY REMNANT
CLOUDINESS/CONVECTION ON D2...AS WELL AS MODEST MID-LEVEL LAPSE
RATES. DESPITE MODERATE MID-LEVEL SWLYS...VEERED LOW-LEVEL FLOW
SHOULD LIMIT GREATER EFFECTIVE SHEAR. PROSPECTS FOR ORGANIZED SEVERE
TSTMS IN NRN MN APPEAR TOO LOW TO WARRANT PROBABILITIES ATTM.
IN FL...BASED ON THE TRACK IN LATEST NHC FORECAST AND CONSENSUS OF
GUIDANCE...ANY TORNADO RISK ASSOCIATED WITH TC ISAAC SHOULD NOT
DEVELOP UNTIL AFTER 12Z/SUN.
