NWS Fort Worth, TX wrote its last area forecast discussion before the first event at Jul 8, 5:53 AM CST, 7 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE FORT WORTH TX 653 AM CDT WED JUL 8 2015 .AVIATION... /12Z TAFS/ CONCERNS...MVFR CEILINGS AND IFR VSBY WITH HEAVY RAIN. A BAND OF SHOWERS WITH EMBEDDED HEAVY RAIN CONTINUES TO SLOWLY APPROACH METROPLEX TAF SITES. FORT WORTH AIRPORTS WILL HAVE THE BEST CHANCE OF SEEING RAIN THIS MORNING. MVFR CEILINGS WILL ACCOMPANY THE ACTIVITY...AND THE HEAVIEST DOWNPOURS MAY REDUCE THE VISIBILITY INTO THE IFR CATEGORY. THE ACTIVITY WILL GRADUALLY DIMINISH IN INTENSITY BY MIDDAY AS THE LLJ WEAKENS. TONIGHT WILL BE RAIN-FREE REGIONWIDE...BUT MVFR CEILINGS WILL LIKELY RETURN IN TIME FOR THE MORNING PUSH ON THURSDAY. 25 && .PREV DISCUSSION... /ISSUED 320 AM CDT WED JUL 8 2015/ A LINE OF RAIN AND A FEW EMBEDDED THUNDERSTORMS DEVELOPED ALONG A QUASI-STATIONARY COLD FRONT THAT IS CURRENTLY SITUATED FROM NEAR GAINESVILLE TO MINERAL WELLS TO COMANCHE. CONVECTIVE ACTIVITY INCREASED DURING THE LATE EVENING AND OVERNIGHT HOURS AS A LOW LEVEL JET ORGANIZED ACROSS THE REGION AND ENHANCED LIFT ACROSS THE BOUNDARY. THIS CONVECTION IS EXPECTED TO CONTINUE TO PERSIST WITH REDEVELOPING CELLS ESSENTIALLY TRACKING ACROSS THE SAME AREA THROUGH THE MORNING HOURS. BY MIDDAY THE BAND MAY SHIFT NORTHWARD AND REORIENT ITSELF IN A MORE WEST TO EAST CONFIGURATION AS THE FRONT BEGINS TO RETREAT NORTHWARD IN RESPONSE TO THE PRESSURE FALLS OCCURRING ACROSS THE PLAINS. THUS SEVERAL MORE HOURS OF RAINFALL IS FORECAST ACROSS THE WESTERN AND NORTHWESTERN ZONES...WHICH MEANS FLASH FLOODING AND RIVER FLOODING WILL BE A CONCERN THROUGH THE MORNING HOURS. THE FLASH FLOOD WATCH CONTINUES THROUGH NOON...AND THERE IS A POSSIBILITY IT COULD BE EXTENDED A FEW HOURS...BUT BELIEVE RAINFALL COVERAGE AND INTENSITY WILL RAPIDLY DIMINISH BY EARLY AFTERNOON. A VERY TIGHT POP GRADIENT EXISTS OVER THE REGION TODAY...WITH 80-100 PERCENT OVER THE NW ZONES...DROPPING DOWN TO 10-20 PERCENT SOUTH OF A GOLDTHWAITE TO WAXAHACHIE TO SULPHUR SPRINGS LINE. IN FACT ACROSS THE METROPLEX...WE HAVE 80 PERCENT IN NW TARRANT COUNTY AND JUST 20 PERCENT IN SE DALLAS COUNTY. THE EASTERN-MOST COUNTIES OF THE FLASH FLOOD WATCH MAY ESCAPE THE HEAVY RAINFALL...BUT THERE IS NOT ENOUGH CONFIDENCE TO CANCEL THEM AT THIS TIME. THIS IS BECAUSE THE CONVECTION MAY PRODUCE ENOUGH OF A COLD POOL FOR IT TO TRY TO BUILD EASTWARD INTO THE LOW LEVEL FLOW RESULTING IN AN EASTWARD SHIFT OF THE HEAVY RAIN AXIS. AGAIN THE PROBABILITY OF THIS OCCURRING IS LOW...BUT NOT LOW ENOUGH TO START CLEARING COUNTIES FROM THE WATCH AT THIS TIME. THE CONVECTION THAT HAS DEVELOPED HAS BEEN VERY EFFICIENT AT PRODUCING HEAVY RAINFALL WITH RAIN RATES UP TO 2 INCHES PER HOUR. STANDARD LEGACY RADAR RAINFALL ESTIMATES WERE UNDERESTIMATING RAIN TOTALS BY A FACTOR OF 2 AND THE KFWS RADAR WAS SWITCHED TO A TROPICAL Z-R RELATIONSHIP WHICH SHOULD DO A BETTER JOB AT ESTIMATING RAINFALL THROUGH THE REMAINDER OF THE EVENT. STILL WOULD NOT BE SURPRISED TO SEE RADAR UNDERESTIMATION CONTINUE GIVEN THE VERY FAVORABLE MOISTURE AND THERMODYNAMIC ENVIRONMENTAL PROFILE FOR RAIN TO FORM FROM COLLISION-COALESCENCE. THIS PROCESS IS BASICALLY THE SLOW AMALGAMATION OF TINY SUSPENDED WATER DROPLETS INTO BIGGER RAINDROPS. USUALLY MOST OF THE RAINFALL WE RECEIVE HERE IS FROM A PROCESS THAT INVOLVES ICE PARTICLES IN THE CLOUD...WHICH IS SIGNIFICANTLY LESS EFFICIENT AT CONVERTING WATER VAPOR INTO PRECIPITATION THAT REACHES THE GROUND. RAINDROPS FORMED VIA COLLISION-COALESCENCE TEND TO BE MUCH SMALLER AND THEREFORE THE RADAR REFLECTIVITY SIGNAL IS MUCH LOWER. SO IN THIS SITUATION EVEN 40-50 DBZ ECHOES ARE INDICATIVE OF HEAVY RAIN. HIGH TEMPERATURES WILL BE UNSEASONABLY COOL OVER THE NORTHWESTERN ZONES TODAY...LIKELY ONLY TOPPING OUT NEAR 80...BUT IT WILL BE INCREASINGLY WARMER AND MORE SEASONAL THE FARTHER SOUTHEAST ONE TRAVELS ACROSS THE CWA WITH LOW 90S FORECAST FOR THE SOUTHEAST ZONES. SOUTH WINDS WILL CONTINUE AT 10 TO 15 MPH INTO TONIGHT. WILL KEEP TONIGHT/S FORECAST RAIN-FREE OVER THE ENTIRE AREA WITH LOWS NEAR NORMAL IN THE LOW TO MID 70S. THE REMAINDER OF THE FORECAST CONTINUES TO FEATURE A STRONG UPPER LEVEL HIGH THAT BUILDS IN FROM THE EAST AND THEN PARKS ITSELF JUST NORTHWEST OF THE REGION BY EARLY NEXT WEEK. THIS WILL TURN ON THE HEAT OVER THE ENTIRE REGION WITH TEMPERATURES CLIMBING SOME EACH DAY. HIGHS COULD FLIRT WITH THE CENTURY MARK IN SOME AREAS BY TUESDAY OR WEDNESDAY OF NEXT WEEK...BUT CONTINUED SOUTHERLY LOW LEVEL FLOW MAY KEEP HIGH TEMPS IN CHECK IN THE MID TO UPPER 90S. REGARDLESS OF THE EXACT TEMPERATURE FORECAST...STRONG SUBSIDENCE FROM THIS RIDGE WILL SQUASH ANY PROSPECTS FOR RAINFALL...SO A DRY FORECAST LOOKS LIKE A SURE BET FROM THURSDAY WELL INTO NEXT WEEK.
