What happened
The episode as NWS BGM wrote it up.
A strong low pressure system moved through the Great Lakes on Monday, the 13th, and pulled a warm front north into central New York. Moist air streaming northward with this warm front brought showers with embedded heavier rains from thunderstorms to central NY. The heaviest rain was concentrated in Cortland County where between 1 and 2 inches of rain fell in a couple hours. This heavy rain caused flash flooding in McGraw, Homer and Cortland. Law enforcement officials reported road closures from water over roadways, mudslides and uprooted trees from gusty winds and a saturated ground. Several basements were also flooded in McGraw.

Area forecast discussion, Mar 13, 4:15 PM EST, 2 hours 45 minutes before
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE BINGHAMTON NY 415 PM EST MON MAR 13 2006 .SHORT TERM (TONIGHT - WEDNESDAY)... MAIN CONCERN WITH THIS FORECAST PACKAGE WILL BE SEVERE THUNDERSTORM THREAT TONIGHT AS A STRONG COLD FRONT MOVES ACROSS THE AREA ACCOMPANIED BY VERY STRONG WIND FIELDS BUT LIMITED INSTABILITY. PRE-FRONTAL LINE OF SHOWERS AND THUNDERSTORMS HAS SHOWN SIGNS OF STRENGTHENING ACROSS WESTERN PA THIS AFTERNOON. COLD FRONT IS STILL BACK ACROSS WESTERN OHIO AND WILL MOVE ACROSS THE FORECAST AREA LATE THIS EVENING THROUGH THE EARLY MORNING HOURS TUESDAY. SCATTERED STORMS HAVE DEVELOPED ALONG THE FRONT FROM MICHIGAN TO OHIO BUT NOTHING ORGANIZED YET. STRONG WINDS APPEAR TO BE SHEARING APART THESE STORMS TRYING TO FORM IN LIMITED INSTABILITY SO FAR. ALL SIGNS POINT TO VERY LIMITED INSTABILITY ACROSS OUR AREA THIS EVENING. TEMPERATURES HAVE CLIMBED INTO THE LOWER 70S ACROSS NORTHERN PA THIS AFTERNOON HELPING TO PRODUCE A LITTLE INSTABILITY IN THAT AREA. FARTHER NORTH CLOUDS AND SHOWERS HAVE KEPT HEATING TO A MINIMUM ACROSS CENTRAL NY. UPPER-LEVEL TROUGH / COLD POOL IS LIFTING NNE ACROSS THE CENTRAL TO WESTERN GREAT LAKES. AS A RESULT... THE STEEPEST MID-LEVEL LAPSE RATES WILL REMAIN WEST OF THE AREA THIS EVENING. DESPITE THESE NEGATIVES...

WARM TEMPERATURES AND SNOW MELT IN THE ADIRONDACKS CAUSING SIGNIFICANT RISES ALONG THE MOHAWK RIVER IN ONEIDA COUNTY. A FLOOD WATCH HAS BEEN ISSUED TO COVER THAT THREAT. ONCE THE FRONT PASSES EAST OF THE AREA LATE TONIGHT... EXPECT A DRY SLOT WITH SHOWERS ENDING... THEN SOME WEAK LAKE EFFECT SNOW AND RAIN SHOWERS DEVELOPING TUESDAY AFTERNOON. WEST WINDS WILL BE STRONG... AND COULD APPROACH ADVISORY CRITERIA TUESDAY AFTERNOON AND TUESDAY EVENING... HOWEVER WITH MORE IMMEDIATE THREATS TONIGHT DECIDED TO LET LATER SHIFTS HANDLE ANY WIND ADVISORY FOR LATE TUESDAY. LAKE EFFECT SNOW SHOULD BECOME ORGANIZED AFTER SUNSET TUESDAY NIGHT AND CONTINUE INTO WEDNESDAY WITH ABOUT A 270 TO 290 FLOW ORIENTATION. THAT WOULD THREATEN THE AREA ALONG AND NORTH OF THE THRUWAY WITH ACCUMULATING SNOWS. HAVE COVERED THIS WITH 2 TO 4 OR 1 TO 3 INCH SNOWFALL ACCUMULATIONS FOR NOW ON TUESDAY NIGHT... WITH MORE EXPECTED WEDNESDAY... ALTHOUGH THE TENDENCY WILL BE FOR THE SNOW TO BECOME DISORGANIZED DURING THE DAYTIME HEATING WEDNESDAY. ADVISORIES MAY HAVE TO BE CONSIDERED FOR TUESDAY NIGHT INTO WEDNESDAY ON LATER SHIFTS. - MSE && .AVIATION (13/18Z - 14/18Z)... -SHRA EXPECTED THRU 00Z AS WARM FRONT MOVES ACROSS THE AREA.
