I AM RELUCTANT TO TOTALLY DISCOUNT THE NAM SO WILL MENTION CHC SHWRS/TSTMS FOR AREAS FROM THE GENESEE VALLEY WEST WITH SLGT CHC FURTHER TO THE EAST. SPC SHOWS SOME CONCERN FOR POTENTIAL FOR SVR BUT TOO EARLY TO GO WITH SLGT RISK AT THIS TIME AS CONVECTIVE COVERAGE IS UNCERTAIN GIVEN LACK OF SUBSTANTIAL MID-UPPER LEVEL INFLUENCES OUTSIDE ANY POSSIBLE MCV...AS WELL AS RATHER NEBULOUS BOUNDARY LAYER FORCING S OF ST LAWRENCE VALLEY FRONTAL ZONE.

WESTERN NY WILL BE ALONG THE NORTHERN PERIPHERY OF HIGH PRESSURE ALOFT WHICH WILL BUILD ACROSS THE MID ATLANTIC STATES DURING THIS PERIOD. THERE WILL BE A ZONE OF FAST WESTERLIES ACROSS ONTARIO AND QUEBEC WHICH WILL KEEP A FRONTAL BOUNDARY JUST TO OUR NORTH. CONVECTION IS POSSIBLE CLOSE TO THIS BOUNDARY.

IN THE PREDAWN HRS EXPECT SOME FOG TO FORM THAT WILL LOWER VSBYS TO THE MVFR RANGE AT IAG/ROC/ART BUT AT THIS TIME WILL LOWER VSBYS TO 6SM AT BUF. ACROSS THE SOUTHERN TIER VSBYS ARE EXPECTED TO LOWER TO LIFR RANGE IN FOG AND PSBLY LOWER FROM ARND 09Z-11Z. VSBYS SHLD IMPROVE TO VFR BY 12Z-13Z.
