Area forecast discussion, Jul 17, 10:53 PM CDT, 2 hours 5 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SHREVEPORT LA 1053 PM CDT THU JUL 17 2014 .AVIATION... RAIN HAS COME TO AN END AT THE TYR/GGG TERMINALS WITH THE BACK EDGE OF RAIN LIKELY EXITING THE TXK TERMINAL SHORTLY AFTER THE 06Z HOUR. THIS IS A MAJOR CHANGE IN TERMINAL FORECASTING THINKING COMPARED TO THE 00Z TAF PACKAGE WHEN IT APPEARED THAT SHRA/TSRA WOULD BE AFFECTING ALL TERMINAL LOCATIONS THROUGH THE OVERNIGHT HOURS. CONVECTION SEEMS TO BE CONFINED TO THE LFK TERMINAL ONLY...CLOSER TO THE WARM FRONT. ELSEWHERE...JUST LOOKING AT LIGHT TO MODERATE SHOWERS WITH VSBYS MOSTLY IN THE 3-5 MILE RANGE AND CEILINGS MOSTLY IFR. FOR THE REMAINING OVERNIGHT HOURS...KEPT THE ABOVE THINKING WITH THE HRRR SUGGESTING WE WILL SEE CONVECTION ENDING FROM WEST TO EAST ACROSS THE REMAINING TERMINALS AFTER THE 12Z FRI HOUR. OBVIOUSLY...CONVECTION WILL HANG ON A LITTLE LONGER AT THE MLU TERMINAL. CEILINGS WILL BE SLOW TO LIFT ON FRIDAY FROM WEST TO EAST BUT THEY SHOULD GRADUALLY BECOME MVFR FROM WEST TO EAST DURING THE DAY. WINDS WILL BE MOSTLY VARIABLE NEAR 5KTS...EVENTUALLY BECOMING NORTHWEST TO NORTHERLY NEAR 5-10KTS WITH THE SLOW PASSAGE OF A COLD FRONT. 13 && .PREV DISCUSSION... /ISSUED 926 PM CDT THU JUL 17 2014/ DISCUSSION... MAJOR UPDATE FOR THIS EVENING AS THE HEAVY RAIN HAS SHIFTED SOUTH. THIS HAS RESULTED IN THE CANCELLATION OF THE FLASH FLOOD WATCH FOR SOUTHWEST ARKANSAS...SOUTHEAST OKLAHOMA AND NORTHEAST TEXAS. FOR THE REMAINDER OF TONIGHT INTO FRIDAY...QFP AND POP GRIDS HAVE BEEN UPDATED TO SHOW THIS TREND. DEEP EAST TEXAS INTO ADJACENT WESTERN LOUISIANA WILL RECEIVE THE HIGHEST RAINFALL TOTALS GOING FORWARD... BUT AMOUNTS AND RAINFALL RATES DO NOT LOOK HIGH ENOUGH TO ISSUE A WATCH ATTM. ON FRIDAY...THE UPPER TROUGH WILL CROSS THE REGION...WITH RAINFALL ENDING FROM WEST TO EAST. TEMPERATURE AND DEWPOINT GRIDS HAVE ALSO BEEN UPDATED FOR TONIGHT INTO FRIDAY...TO SUPPORT THE WARM FRONTAL BOUNDARY WHICH REMAINS SOUTH OF THE CWA...FROM NEAR BPT TO CLL. IT MAY MOVE A LITTLE MORE NORTH OVERNIGHT...WHICH WILL BRING TEMPS AND DEWPOINTS UP AFTER MIDNIGHT IN SOUTHERN AREAS...BUT ONLY A SMALL CHANGE FROM CURRENT LEVELS.
