NWS Fort Worth, TX wrote its last area forecast discussion before the first event at Jul 8, 2:43 PM CST, 1 hour 7 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE FORT WORTH TX 343 PM CDT SUN JUL 8 2012 .DISCUSSION... SCATTERED THUNDERSTORMS ARE DEVELOPING ACROSS THE REGION AS STRONG INSOLATION HAS RESULTED IN UNCAPPED MODERATE INSTABILITY. SO FAR THE CONVECTION HAS BEEN BROADLY FOCUSED IN A ZONE OF LOW LEVEL CONFLUENCE...AS DEPICTED BY 850-925MB WIND ANALYSIS...EXTENDING FROM WEST TEXAS TO CENTRAL TEXAS AND INTO EAST TEXAS. ANOTHER AREA OF CONVERGENCE...THIS ONE ASSOCIATED WITH A WEAK COLD FRONT...IS LOCATED ACROSS CENTRAL OKLAHOMA AND ARKANSAS. THROUGH EARLY EVENING...EXPECT ACTIVTY ACROSS THE SOUTHERN ZONES TO SLOWLY WORK SOUTHWARD. A FEW HIT-MISS SHOWERS/STORMS WILL CONTINUE TO BUBBLE UP ELSEWHERE...WITH MORE ORGANIZED ACTIVITY ACROSS EASTERN OKLAHOMA AND ARKANSAS LIKELY SHIFTING SOUTHWEST AND MAKING A RUN AT THE NORTHEAST ZONES IF IT CAN HOLD TOGETHER AFTER SUNSET. WILL CONTINUE CHANCE POPS ACROSS MOST OF THE REGION TONIGHT WITH BEST CHANCES IN THE EAST. AN UPPER LEVEL TROUGH AXIS WILL REMAIN DRAPED OVER THE REGION DURING THE NEXT FEW DAYS. THIS WILL TEND TO KEEP THE BEST LIFT LOCATED ACROSS THE SOUTHEAST HALF OF THE CWA. PRECIPITABLE WATER WILL CONTINUE TO INCREASE DURING THE NEXT DAY...WITH MODEL FORECASTS BRINGING VALUES UP TO 2-2.2 INCHES. THE COLUMN WILL BE NEARLY SATURATED ABOVE 800MB...WHICH WILL PROMOTE MOSTLY CLOUDY SKIES...ESPECIALLY IN THE OVERNIGHT AND MORNING HOURS. HIGH TEMPERATURES WILL NOT BE AS WARM DUE TO THE INCREASED CLOUD COVER AND RAIN IN THE AREA...AS WELL AS GRADUALLY DIMINISHING HEIGHTS. CONVECTION SHOULD BE SCATTERED AGAIN BY TOMORROW AFTERNOON...WITH A LITTLE MORE COVERAGE IN ACTIVITY THAN TODAY AS THE WEAK COLD FRONT WILL BE IN THE REGION TO HELP PROVIDE LIFT. BY MONDAY NIGHT...BOTH THE GFS AND ECMWF FORECASTS ARE INDICATING SUBTLE DEEPENING OF A 700MB LOW CENTER WHICH APPEARS TO TRACK FROM NORTHEAST TO SOUTHWEST ACROSS THE SOUTHEAST CWA. CONSIDERING THE DEEP MOISTURE ALREADY IN PLACE...THIS WOULD LIKELY RESULT IN A ROUND OF NOCTURNAL CONVECTION WHICH WOULD TEND TO BE CONCENTRATED NEAR THE LOW CENTER. BOTH MOS PRODUCTS FROM THESE MODELS ARE SUGGESTING POPS IN THE 60-80 PERCENT RANGE...BUT AM NOT READY TO GO THIS HIGH JUST YET. THERE IS STILL SOME UNCERTAINTY ON THE TRACK OF THE LOW IF IT DOES INDEED DEVELOP. A LOW OF THIS TYPE MAY RAISE CONCERN FOR AN ORGANIZED FLOODING THREAT MONDAY NIGHT AND TUESDAY MORNING SINCE IT WOULD BE ABLE TO CONCENTRATE AND SUSTAIN CONVECTION IN ONE AREA FOR SEVERAL HOURS. REGARDLESS OF WHETHER THIS LOW DOES FORM...DIURNAL HEATING TUESDAY WILL RESULT IN ANOTHER ROUND OF SCATTERED CONVECTION BY THE AFTERNOON HOURS. AMPLIFYING UPPER LEVEL FLOW WITH A STRONG RIDGE BUILDING OVER THE INTER-MOUNTAIN WEST WILL RESULT IN NORTHERLY FLOW AT ALL LEVELS BY TUESDAY NIGHT. THIS WILL GRADUALLY BRING DRIER AIR INTO THE REGION WEDNESDAY AND THURSDAY AND POPS WILL DIMINISH FROM NORTH TO SOUTH. WILL KEEP SOME LOW POPS IN THE AFTERNOON ACROSS THE SOUTHEAST ZONES FRIDAY THROUGH SUNDAY AS PWS REMAIN ABOVE 1.75 IN THIS REGION AND THE WEAKNESS WILL PERSIST ALOFT. HIGH TEMPS WILL WARM SLIGHTLY INTO THE MID 90S BY NEXT WEEKEND WITH THE INCREASED SUNSHINE BUT DRIER AIR...LIGHT WINDS...AND CLEAR SKIES WILL HELP LOWS TO COOL OFF MORE INTO THE LOW 70S. EXTENDED MODELS KEEP THE UPPER LEVEL WEAKNESS IN PLACE AND THE GULF OPEN FOR MOISTURE NEXT WEEK. LOOKS LIKE TEMPS WILL STAY NEAR NORMAL WITH AT LEAST ISOLATED AIRMASS CONVECTION IN THE FORECAST.
