HPC Precip Totals Thursday-Friday

Showers developing overnight as a warm front appraoches the region.  The front stalls out over us on Thursday.  Two waves (low pressure) will move along the front, the first moves through the region Thursday morning-early afternoon, with moderate/heavy rain.  The second and much stronger one arrives late Thursday evening/night producing heavy rain and a few strong storms (right now the risk for severe weather looks to stay to our south and west).  

As you can see HPC has us in the Bull's Eye for the heaviest rain!  Most areas should see 2-4" of rain with locally 5" south of the Metro.  Our record for Feb 24th is 1.49" set in 1965 and it looks like we will break that old record!  And the last time we saw an inch or more of rain... November 30, 2010 -1.16"

A Flood Watch is in effect Thursday 7:00am to Friday 7:00am for the Kentucky.

MODERATE TO HEAVY RAINFALL IS EXPECTED ACROSS KENTUCKY BEGINNING EARLY THURSDAY. RAINS ARE EXPECTED TO PERSIST THROUGHOUT THE DAY THURSDAY WITH THE HEAVIEST RAINS AND SCATTERED THUNDERSTORMS LIKELY THURSDAY EVENING AND NIGHT. RAINFALL TOTALS ARE EXPECTED TO BE IN THE 2 TO 4 INCH RANGE WITH LOCALLY HIGHER AMOUNTS OF 5 INCHES POSSIBLE THURSDAY AND THURSDAY NIGHT WHICH COULD CAUSE FLASH FLOODING PROBLEMS. AREAS AT MOST RISK FOR FLASH FLOODING INCLUDE URBAN AREAS WITH POOR DRAINAGE; ANY LOW LYING AREAS; AND SMALL CREEKS, STREAMS AND RIVERS. AT THIS TIME SOUTHERN INDIANA IS NOT UNDER A FLASH FLOOD WATCH, BUT LOCALIZE FLOODING IS POSSIBLE.
