DISCUSSION
MOISTURE CONTINUES TO STREAM UP FROM THE SOUTH BRINGING
WIDESPREAD SHOWERS AND THUNDERSTORMS TO THE AREA. SLOW MOVING
STORMS CONTINUE TO BRING FLASH FLOODING CONCERNS TO BURN SCARS AND
OTHER SUSCEPTIBLE TERRAIN. THIS TREND WILL CONTINUE FRIDAY WITH
MOISTURE CONTENT LOWERING HEADING INTO THE WEEKEND THOUGH RESIDUAL
MOISTURE WILL ALLOW SOME CONVECTION OVER THE HIGHER TERRAIN. THE
NEXT CHANCE FOR WIDESPREAD PRECIP WILL BE THE MIDDLE OF NEXT WEEK
ONWARDS.
...GUSTY ERRATIC WINDS CAN BE EXPECTED NEAR ANY SHOWERS
OR THUNDERSTORMS...
