AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX 404 PM CDT MON MAY 26 2014 .DISCUSSION... PROPAGATION OF THE OVERNIGHT PCPN THROUGH SE TX THIS AFTN LIKELY HELPED BY SPLITTING JET ALOFT/INFLUX OF ABUNDANT LOW-LEVEL MOIST- URE FROM THE GULF. SAVE FOR THE LEADING TSRA (WHICH PROMPTED THE WARNINGS) THE REST OF THE ACTIVITY SHOULD CONTINUE TO BE GENERAL- LY MODERATE/HEAVY RAINFALL PRODUCERS. NOT SEEING MUCH BEHIND THE SYSTEM...SO WITH THE LOSS OF DAYTIME HEATING WILL EXPECT A BREAK OVERNIGHT. BUT PER WV IMAGERY ADDITIONAL DISTURBANCES SEEM TO BE HEADED THIS WAY.
