DISCUSSION...  
WEATHER MAP SHOWING MAINLY EASTERLY FLOW OVER THE AREA. RADAR  
SHOWS SCATTERED TO NUMEROUS SLOW MOVING SHOWERS AND THUNDERSTORMS  
OVER MOST OF THE AREA THIS AFTERNOON. SOME OF THESE STORMS  
PRODUCED 3-5" OF RAIN OVER CENTRAL BEAUMONT PER DD6 GAUGES WITH  
FLASH FLOOD WARNING CONTINUING OVER THE REGION. OTHER AREAS OF  
2-4" OCCURRING THE LAST 3 HOURS OVER SE CALCASIEU PARISH AND  
BETWEEN THE SOUTHERN END OF CALCASIEU LAKE AND CAMERON.  
 
THE UPPER LEVEL TROUGH/LOW OVER THE TEXAS COAST AND WESTERN GULF  
WILL BE SLOW MOVING THROUGH FRIDAY. THIS COUPLED WITH CONTINUED  
HIGH GULF MOISTURE (PRECIP H20 EXPECTED TO BE AT OR ABOVE 2"  
THROUGH FRIDAY), PERIODS OF SHOWERS AND THUNDERSTORMS, WITH THE  
BEST CHANCES ALONG AND SOUTH OF I-10 INTO THE COASTAL WATERS AT  
ANY GIVEN TIME, CAN BE EXPECTED. DUE TO THE SLOW MOVEMENT,  
ISOLATED LOCATIONS COULD SEE MINOR FLOODING, ESPECIALLY LOCATIONS  
THAT ARE EXCEEDINGLY WET FROM THE RECENT RAIN.  
 
BY FRIDAY EVENING INTO THE WEEKEND, THE MID LEVEL TROUGH AXIS  
SHOULD MOVE EAST OF THE AREA WITH HIGH PRESSURE AND SLIGHTLY  
DRIER AIR ALOFT IS EXPECTED TO DIMINISH SHOWER AND THUNDERSTORM  
CHANCES TO NEAR ~20% OR LESS FOR THE WEEKEND THROUGH INDEPENDENCE  
DAY.  
 
DML  
 
MARINE...  
EASTERLY WINDS WILL SHIFT MORE SOUTHEASTERLY TONIGHT AS HIGH  
PRESSURE RIDGES WESTWARD ALONG THE GULF COAST. A DISTURBANCE ALOFT  
AND DEEP TROPICAL MOISTURE OVER THE AREA WILL RESULT IN SCATTERED  
TO NUMEROUS SHOWERS AND THUNDERSTORMS THE NEXT FEW DAYS. WINDS  
AND SEAS WILL BE LOCALLY HIGHER NEAR THUNDERSTORMS. BY THE WEEKEND,  
HIGH PRESSURE AND DRIER AIR ALOFT IS EXPECTED TO LIMIT SHOWER AND  
THUNDERSTORM ACTIVITY, WITH A LIGHT TO MODERATE ONSHORE FLOW  
CONTINUING.
