Area forecast discussion, Jun 13, 3:56 PM CDT, 2 hours 27 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAKE CHARLES LA 356 PM CDT WED JUN 13 2012 .DISCUSSION... LOOKING AT THE CURRENT RADAR, VARIOUS ISOLATED SHOWERS THAT HAD DEVELOPED TO THE SOUTH HAVE SINCE MOVED TO THE NORTHEAST OF THE FORECAST REGION. AS THE SEA BREEZE CONTINUES TO MOVE INLAND, A FEW MORE SHOWERS MAY DEVELOP ALONG THE COAST AND PROGRESS AT A MODERATE PACE. THESE AFTERNOON STORMS ARE NOT ANTICIPATED TO BECOME SEVERE ALTHOUGH BRIEF BUT HEAVY RAIN COULD CONTINUE TO FALL. CURRENTLY WV/IR SAT AND SURFACE ANALYSIS SHOWS A HIGH PRESSURE SYSTEM DOMINATING THE GREAT LAKES REGION BEHIND A WEAK LOW PRESSURE SYSTEM OFF THE COAST OF VIRGINIA. A CORRESPONDING FRONT HAS STALLED OVER EASTERN GEORGIA TO CENTRAL LOUISIANA. THIS STALLED FRONT HAS CONTRIBUTED TO THE ISOLATED STORMS OCCURRING IN OUR FORECAST AREA. THIS SYSTEM WILL SOON DISSIPATE INTO A SHORTWAVE TROUGH INTO THE WEEKEND. AS FAR AS THE FORECAST GOES, TRENDED MORE TOWARDS THE EUROPEAN MODEL. THROUGHOUT THE FORECAST WEEK THE MODEL EXHIBITS ZONAL UPPER LEVEL FLOW INTO THE WEEKEND, WITH RELATIVE HUMIDITY REACHING MODERATE VALUES OF UPPER SIXTIES AT THE SURFACE. EXPECT WITH THE STALLED FRONT AND WARM MOIST CONDITIONS THUNDERSTORM ACTIVITY WILL CONTINUE INTO THE WEEKEND. CHOSE TO KEEP THE POPS FROM THE PREVIOUS FORECAST. WITH ISOLATED ACTIVITY ITS DIFFICULT TO HAVE CONFIDENCE IN EXACTLY WHERE THE ACTIVITY WILL BE. THE TEMPERATURE DIFFERENCES IN THE GULF SHOULD FORM A SEA BREEZE OVER THE NEXT COUPLE OF DAYS. LONG TERM WE HAVE BEGUN A PROGRESSIVE SUMMER PATTERN OF AFTERNOON CONVECTION AND ARE CARRYING A 20 POP FOR MOST OF THE AFTERNOON DAYS. DEAL/STACKHOUSE && .MARINE... A WEAKENING COLD FRONT WILL CONTINUE ACT AS A FOCUS FOR SHOWERS AND STORMS ACROSS THE REGION WHILE UPPER DISTURBANCES MOVE ACROSS THE DEEP SOUTH. THE BOUNDARY WILL DISSIPATE INTO THE WEEKEND AND A RIDGE WILL BUILD IN FROM THE NORTH, HOWEVER A FEW SHOWERS AND STORMS WILL REMAIN POSSIBLE THROUGH THE WEEKEND. && .PRELIMINARY POINT TEMPS/POPS...
