VALID 261200Z - 271200Z

...SYNOPSIS...
A LONGWAVE TROUGH WILL REMAIN CENTERED OVER THE CENTRAL PORTIONS OF
THE CONUS/CANADA ON FRIDAY...WITH A SECONDARY/SOUTHERN PORTION OF
THIS TROUGH EXPECTED TO SPREAD EAST-NORTHEASTWARD OVER THE CENTRAL
PLAINS/MIDWEST THROUGH FRIDAY NIGHT. TSTM POTENTIAL WILL BE
RELEGATED TO AREAS NEAR/AHEAD OF A SOUTHEASTWARD MOVING COLD FRONT
FROM THE OH/TN RIVER VALLEYS TO TX. A COMBINATION OF WEAK
INSTABILITY/POOR MID LEVEL LAPSE RATES AND/OR WEAKENING MASS
CONVERGENCE SHOULD LIMIT THE LIKELIHOOD/COVERAGE OF TSTMS...WITH NO
ORGANIZED SEVERE TSTMS CURRENTLY EXPECTED.

OTHERWISE...PER LATEST NHC TRACK/INTENSITY GUIDANCE...TROPICAL
SYSTEM SANDY IS NOT EXPECTED TO BE A FACTOR FOR NEAR-LAND
SEVERE/TORNADO POTENTIAL ACROSS THE COASTAL SOUTHEAST FRIDAY/FRIDAY
NIGHT.
