...SHIFTING TO A WETTER PATTERN...

A FRONTAL BOUNDARY WILL BE THE FOCUS FOR THUNDERSTORM DEVELOPMENT
OVER THE NEXT FEW DAYS...BEGINNING LATER TONIGHT AND CONTINUING
THROUGH AT LEAST THURSDAY NIGHT. THE ATMOSPHERE WILL BECOME VERY
WARM AND HUMID SOUTH OF THIS FRONT. SO THERE WILL BE PLENTY OF
MOISTURE FOR ANY OF THESE STORMS TO WORK WITH.

THE BEST CHANCE OF STORMS WILL BE LATER TONIGHT INTO THURSDAY
NIGHT. THERE WILL BE A LOWER CONFIDENCE IN STORMS FRIDAY INTO THE
WEEKEND AS AN UPPER RIDGE OF HIGH PRESSURE BUILDS NORTH AND MAY
SUPPRESS STORM DEVELOPMENT IN SPITE OF THE LINGERING FRONTAL
BOUNDARY.

SO WHILE THERE IS CONCERN FOR SOME URBAN AND SMALL STREAM
FLOODING IN THIS REGIME...THERE IS SOME SMALL POTENTIAL FOR FLASH
FLOODING AS WELL ESPECIALLY WHERE ANY STORMS BECOME PERSISTENT OR
TRAVERSE REPEATEDLY ACROSS THE SAME AREAS.

STAY TUNED FOR LATER FORECASTS ON THIS EVOLVING POTENTIAL FOR SOME
HEAVIER RAINFALL.
