NWS Fort Worth, TX wrote its last area forecast discussion before the first event at Jun 18, 2:39 PM CST, 1 hour 31 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE FORT WORTH TX 339 PM CDT THU JUN 18 2015 .DISCUSSION... AFTERNOON WATER VAPOR SATELLITE IMAGERY SHOWS UPPER LEVEL HIGH PRESSURE CIRCULATIONS OVER THE SOUTHEAST AND SOUTHWEST PARTS OF THE CONUS. IN BETWEEN, THE REMNANTS OF TROPICAL STORM BILL WERE EVIDENT OVER EASTERN OKLAHOMA, MOVING SLOWLY TO THE EAST. THIS LEFT NORTH AND CENTRAL TEXAS UNDER A COL IN THE FLOW FIELD ALOFT. WITHIN THIS COL, VISIBLE SATELLITE IMAGERY COMBINED WITH SURFACE OBSERVATIONS SHOWED AN AREA OF DEEP CONVERGENCE LOCATED FROM GOLDTHWAITE NORTHEAST ACROSS HILLSBORO AND OVER CANTON. THIS AREA OF LARGE SCALE CONVERGENCE APPEARS TO STILL BE LOOSELY ATTACHED TO THE REMNANTS OF BILL AS A FAR SOUTHERN FEEDER BAND INTO THE MAIN CIRCULATION. SCATTERED THUNDERSTORMS HAD ALREADY DEVELOPED WITHIN THIS BAND OF CONVERGENCE AT 3 PM...AND THIS ACTIVITY IS LIKELY TO CONTINUE TO DEVELOP THROUGH SUNSET. THIS AFTERNOON...AT THIS TIME WILL SIMPLY HOLD ON TO THE FLASH FLOOD WATCH AS IS WITH THUNDERSTORMS DEVELOPING ALL ALONG THE CONVERGENCE ZONE/FEEDER BAND MENTIONED ABOVE. THESE STORMS ARE SLOW MOVING...AND WILL LIKELY COLLAPSE AND REGENERATE WHILE THERE IS ENOUGH HEATING TO KEEP THE ATMOSPHERE UNSTABLE. PWAT VALUES WERE IN THE 1.75 TO 1.9 INCH RANGE ACCORDING TO SATELLITE ESTIMATES...WHICH IS ACTUALLY DOWN FROM THE PAST COUPLE OF DAYS. THERE IS SOME DRY AIR ALOFT WHICH WILL ALLOW DOWNDRAFTS TO BE COOLER THAN THEY HAVE BEEN THE PAST COUPLE OF DAYS...WHICH MAY DRIVE SOME OUTFLOW BOUNDARIES AND MOVE THE LINE OF DEEP CONVERGENCE. WITHOUT GREAT CONFIDENCE THAT THIS LINE OF SCATTERED STORMS WILL SIMPLY HOLD IN PLACE, DID NOT WANT TO REMOVE COUNTIES FROM THE FLASH FLOOD WATCH AND HAVE THIS LINE DRIFT SOUTHEAST ON OUTFLOW OVER AREAS WHERE IT IS NOT CURRENTLY RAINING. LOCALLY CALCULATED CONVECTIVE ANALYSIS INDICATES THESE STORMS HAVE 2000 TO 2500 J/KG OF CAPE TO WORK WITH...BUT DEEP LAYER SHEAR WAS ONLY ON THE ORDER OF 20 TO 25 KTS. THE LACK OF STRONGER SHEAR WILL LIKELY PREVENT THE STORMS FROM BECOMING VERY ORGANIZED...SO EXPECT THAT A MULTI-CELL CLUSTER WILL BE THE PREFERRED STORM MODE. DOWNBURST WINDS WILL BE POSSIBLE, BUT HEAVY RAINFALL AND FLOODING ARE EXPECTED TO BE THE MAIN THREATS. THERE IS A BRIEF TORNADO THREAT...PRIMARILY DUE TO THE POTENTIAL FOR LANDSPOUTS. THE SURFACE CONVERGENCE ZONE DOES HAVE SOME WEAK VERTICAL VORTICITY ASSOCIATED WITH IT. ANY STRONG UPDRAFT THAT DEVELOPS RIGHT ON THE CONVERGENCE LINE WILL STRETCH THIS VERTICAL VORTICITY...POSSIBLY RESULTING IN ENOUGH CONTRACTION FOR A LANDSPOUT TORNADO TO DEVELOP. THE WINDS ON EITHER SIDE OF THE CONVERGENCE ZONE ARE ONLY SUPPORTIVE OF SOME WEAK VERTICAL VORTICITY AT THIS TIME...SO DO NOT THINK LANDSPOUTS WILL BE COMMON BY ANY MEANS...BUT CAN NOT RULE OUT ONE OR TWO OF THESE ALONG THE BOUNDARY THROUGH SUNSET. AFTER SUNSET...THE LANDSPOUT TORNADO THREAT WILL DECREASE RAPIDLY AS LANDSPOUTS REQUIRE SOME LOW-LEVEL (0-3 KM MOST COMMONLY USED TO ASSESS) CAPE TO SUPPORT LOW-LEVEL VERTICAL MOTIONS FAST ENOUGH TO STRETCH AND CONTRACT THE LOW-LEVEL VORTICITY INTO A TORNADO. LOW- LEVEL CAPE DISAPPEARS VERY QUICKLY AS WE LOSE DAYTIME HEATING. THE THREAT FOR HEAVY RAINFALL COULD CONTINUE HOWEVER...AND THIS IS REALLY THE GREATEST POINT OF UNCERTAINTY IN THE FORECAST. SOME MODEL GUIDANCE INDICATES THAT WE LOSE MOST OF THE CONVECTIVE ACTIVITY ALONG THE CONVERGENCE ZONE/FEEDER BAND AFTER WE LOSE DAYTIME HEATING. OTHER GUIDANCE INDICATES THAT AFTER WE LOSE DAYTIME HEATING...LOW-LEVEL CONVERGENCE ACTUALLY INCREASES A BIT...AND CAUSES A BAND OF SLOW-MOVING...AND POSSIBLY BACK BUILDING...THUNDERSTORMS TO DEVELOP. IF THIS OCCURS, THERE WOULD VERY LIKELY BE A NARROW CORRIDOR OF FLASH FLOODING AS THIS NEW DEVELOPMENT MAY CONTINUE FOR SEVERAL HOURS...INTO THE EARLY MORNING HOURS OF FRIDAY. AT THIS TIME, MORE GUIDANCE SUPPORTS THE LOSS OF CONVECTION RATHER THAN THE REDEVELOPMENT, SO SHOWED A GENERAL LOWERING OF RAIN CHANCES THROUGHOUT THE OVERNIGHT HOURS. IF REDEVELOPMENT LOOKS IMMINENT THIS EVENING, MAY HAVE TO EXTEND SOME PORTION OF THE FLASH FLOOD WATCH THROUGH EARLY FRIDAY MORNING. UNFORTUNATELY WE WILL HAVE TO WAIT AND SEE HOW THINGS PAN OUT OVER THE NEXT FEW HOURS BEFORE MAKING THAT DISTINCTION. FRIDAY THROUGH SUNDAY...THE REMNANTS OF BILL ARE EXPECTED TO MOVE EAST TOWARDS THE TENNESSEE VALLEY RESULTING IN SUBSIDENCE OVER MOST OF NORTH TEXAS ON FRIDAY. MODELS HOLD ON TO THE GENERAL WEAKNESS IN THE FLOW FIELD ALOFT OVER CENTRAL TEXAS HOWEVER BETWEEN THE TWO RIDGES TO OUR WEST AND EAST. THE LATEST MODEL GUIDANCE CONTINUES THE TREND OF INDICATING THAT A WEAK UPPER LEVEL TROUGH WILL STRENGTHEN A BIT OVER MEXICO FROM FRIDAY THROUGH THE UPCOMING WEEKEND. MOST MODEL GUIDANCE INDICATES THAT THIS UPPER TROUGH EXTENDS NORTHWARD OVER THE HILL COUNTRY...SO LEFT SOME LOW POPS OVER THE FAR SOUTHERN CWA TO ACCOUNT FOR THE WEAK LIFT ASSOCIATED WITH THIS INVERTED TROUGH NEAR CENTRAL TEXAS. MOST OF NORTH AND CENTRAL TEXAS IS EXPECTED TO REMAIN DRY WITH SUBSIDENCE LEAVING AN INVERSION IN PLACE OVER THE REGION IN THE WAKE OF BILL. EXPECT MOSTLY SUNNY SKIES AND A QUICK WARM UP DUE TO THE HIGH SUN ANGLE ASSOCIATED WITH THE SUMMER SOLSTICE. NEXT WEEK...THE UPPER LEVEL RIDGE OVER THE SOUTHWESTERN CONUS IS EXPECTED TO BUILD EAST OVER THE SOUTHERN PLAINS. THIS SHOULD KEEP THE CWA WARM AND DRY FOR MUCH OF THE WEEK AHEAD. HOWEVER BY LATE IN THE WEEK...THE WEAK INVERTED TROUGH IS EXPECTED TO MOVE OVER THE FAR WESTERN TEXAS PANHANDLE...NEAR EL PASO. UPPER LEVEL RIDGING IS EXPECTED TO BUILD IN INTENSITY OVER THE SOUTHEASTERN CONUS RESULTING IN DEEP SOUTHERLY FLOW OFF THE GULF OF MEXICO AND OVER THE CWA. WHILE THIS FLOW REGIME DOESN'T NECESSARILY SUPPORT LIFT OR SUBSIDENCE OVER THE REGION...IT IS EXPECTED TO ADVECT A DEEP TROPICAL AIR MASS INTO THE AREA...RESULTING IN AT LEAST ISOLATED THUNDERSTORMS DURING THE PEAK HEATING HOURS OF THE DAY. ONLY PLACED A 20 POP IN PLACE ACROSS CENTRAL TEXAS...CLOSER TO THE SOURCE DEEP TROPICAL MOISTURE. CAVANAUGH && .AVIATION... /ISSUED 102 PM CDT THU JUN 18 2015/ /18Z TAFS/ CONCERNS...THUNDERSTORMS THIS AFTERNOON AND MVFR CIGS FRIDAY MORNING AT KACT. POSSIBLE THUNDERSTORMS AND MVFR CIGS IN THE METROPLEX. KACT...SCATTERED SHOWERS AND THUNDERSTORMS ARE ALREADY DEVELOPING AROUND KACT AND WILL CARRY A VCTS WITH VFR CONDITIONS OTHERWISE THROUGH THE AFTERNOON. MODEL GUIDANCE CONTINUES TO FORECAST MVFR CIGS AT KACT FRIDAY MORNING AND WILL RETAIN THE BKN017 FROM 09-14Z. THERE IS A CHANCE THE STRATUS MAY NOT HAPPEN AND WILL UPDATE THE TAF AS NECESSARY. SOUTH WINDS GENERALLY AOB 10 KTS WILL PREVAIL. DFW AIRPORTS... WILL CARRY VFR CONDITIONS THIS AFTERNOON AND EVENING BUT WILL BE CLOSELY MONITORING FOR ISOLATED CONVECTION AFFECTING ANY OF THE DFW TAF SITES. MOST OF THE GUIDANCE SUGGESTS ANY SHOWERS OR STORMS THIS AFTERNOON WILL MAINLY BE EAST TO SOUTH OF DFW...BUT ITS POSSIBLE ONE MAY DEVELOP OR MOVE NEAR A TAF SITE. THE WINDS THROUGH THE AFTERNOON WILL GENERALLY BE FROM THE WEST AT 8-15 KTS BUT WILL BECOME MORE SOUTHWESTERLY LATE THIS AFTERNOON AND EVENING. THERE IS LOW CONFIDENCE ON THE DEVELOPMENT OF MVFR CIGS AFFECTING THE DFW TAF SITES EARLY FRIDAY MORNING. SOME OF THE GUIDANCE SUGGESTS ONLY KDAL WILL BE AFFECTED BY MVFR STRATUS WHILE THE REMAINING SITES REMAIN VFR. FOR NOW...HAVE OPTED TO PREVAIL A SCT021 GROUP FROM 12-17Z. IT IS POSSIBLE THERE COULD BE A BRIEF TIME PERIOD WITHIN THAT WINDOW WHERE SKIES ARE BROKEN MVFR AT ANY OF THE AIRPORTS. JLDUNN && .PRELIMINARY POINT TEMPS/POPS... DALLAS-FT.
