Area forecast discussion, May 7, 5:30 AM CST, 4 hours 25 minutes before
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE NORMAN OK 630 AM CDT THU MAY 7 2015 .AVIATION...07/12Z TAF ISSUANCE... COMPLICATED AVIATION FORECAST... SCATTERED SHOWERS AND ISOLATED THUNDER WILL PERSIST THROUGH THE MORNING HOURS... WITH BRIEF IMPACTS TO AREA AIRFIELDS. THERE COULD BE A LULL IN ACTIVITY THROUGH A PORTION OF THE LATE MORNING AND EARLY AFTERNOON... BUT STORM CHANCES WILL MAKE A RETURN LATER THIS AFTERNOON AND EVENING. HAVE ENOUGH CONFIDENCE FOR TEMPO GROUPS LATER TODAY AT SOME SITES... BUT CONDITIONS MAY EVOLVE QUICKLY. GUSTY SOUTH WINDS WILL PERSIST THROUGH THE DAY... RELAXING SLIGHTLY THROUGH THE OVERNIGHT HOURS. JTK && .PREV DISCUSSION... /ISSUED 315 AM CDT THU MAY 7 2015/ DISCUSSION... PRIMARY FORECAST CONCERN WILL FOCUS ON TODAY... THIS MORNING... THE EVOLVING MCS OVER SRN OK/WRN N TX WILL PERSIST THROUGH SUNRISE... EXPECT PRIMARILY THUNDERSTORMS... WITH A FEW STRONG TO SEVERE THUNDERSTORMS EMBEDDED WITHIN THE LARGER RAIN SHIELD THROUGH 12Z. ADDITIONAL RAINFALL AMOUNTS WILL BE ANYWHERE FROM A FEW TENTHS TO UP TO ADDITIONAL HALF TO THREE QUARTERS OF AN INCH WITH THE STRONGEST STORMS. DEPENDING ON WHERE THE STRONGEST STORMS SET UP... THIS MAY EXACERBATE ON GOING FLOODING. THROUGH SUNRISE... CONTINUE TO OBSERVE INCREASING ACCAS ACROSS SERN NM/THE PERMIAN BASIN. THIS HAS DEVELOPED IN RESPONSE TO A WELL DEPICTED SUBTLE SHORT WAVE ROUNDING THE BASE OF THE WRN TROUGH... WHICH WILL CONTINUE TO LIFT E/NE THIS MORNING. IN RESPONSE... MESOSCALE GUIDANCE HAS BEEN CONSISTENT IN LIGHTING THIS UP WITH CONVECTION THROUGH THE EARLY MORNING... WITH STORMS SPREADING INTO WRN N TX/SWRN OK THROUGH 10AM. IN ADDITION... TRADITIONAL GUIDANCE FROM THE NAM AND ECMWF HAVE ALSO HINTED AT THIS AREA OF CONVECTION DEVELOPING AND MOVING INTO THE REGION. AS THIS SCENARIO IS LOOKING MORE LIKELY THIS MORNING... THIS WILL HAVE A SIGNIFICANT IMPACT ON HOW TODAY EVOLVES WITH RESPECT TO STORMS IN THE AFTN. AT THE MOMENT... THIS INITIAL MORNING CONVECTION WILL LIKELY RESULT IN A HAIL AND WIND THREAT AS ELEVATED INSTABILITY WILL INCREASE THROUGH THE MORNING HOURS... SFC DPTS HOLD IN THE LOW/MID 60S AND MODEST DEEP LAYER SHEAR REMAINS 30 TO 45KTS. ANY STORMS THIS AM ACROSS WRN OK/WRN N TX WILL SLOWLY MOVE E/NE THROUGH THE EARLY AFTN. STORM DEVELOPMENT THIS AFTERNOON WILL BE HIGHLY CONDITIONAL ON WHAT OCCURS THIS MORNING... PRIMARILY HOW FAST DO ANY EARLY STORMS MOVE EAST/DISSIPATE AND THEN HOW QUICKLY WE CAN RECOVER. THIS IS TRICKY GIVEN THE VARIETY OF SOLUTIONS FROM AVAILABLE GUIDANCE. AT THIS TIME... MOST SUGGEST WE WILL HAVE A WINDOW OF OPPORTUNITY TO CLEAR OUT CLOUD COVER AND TAP INTO THE AFTN SUNSHINE. COMBINING THIS WITH DPTS BUILDING BACK INTO MID 60S AHEAD OF THE DRYLINE IN THE EAST TX PANHANDLE... EXPECT AN AXIS OF MLCAPE VALUES BETWEEN 1500 AND 2500 AHEAD OF THE DRYLINE ALONG THE TX PANHANDLE/OK BORDER. EXPECT A BIT OF A DRYLINE PUSH NEARING WRN OK/WRN N TX LATE AFTN/EVENING. IT APPEARS WE WILL HAVE SUFFICIENT SHEAR AND INSTABILITY FOR SUPERCELLS CAPABLE OF DAMAGING HAIL... WINDS... AND TORNADO DEVELOPMENT... BUT GIVEN HOW UNCERTAIN AND HIGHLY CONDITIONAL TODAY IS... IT IS DIFFICULT TO PIN DOWN ANY MORE SPECIFICS AT THIS MOMENT. JTK && .PRELIMINARY POINT TEMPS/POPS...

LOCALLY HEAVY RAINFALL WILL ALSO OCCUR WITH THE STRONGER STORMS WHICH MAY RESULT IN FLASH FLOODING. .SPOTTER AND EMERGENCY MANAGEMENT STATEMENT... STORM SPOTTER GROUPS AND EMERGENCY MANAGEMENT PERSONNEL IN THE SLIGHT RISK AREA SHOULD BE READY FOR SEVERE WEATHER OPERATIONS. DISCUSSION... A STRONG LOW LEVEL JET WILL CONTINUE TO FOSTER THE DEVELOPMENT OF SCATTERED THUNDERSTORMS ACROSS PARTS OF SOUTH CENTRAL AND SOUTHEAST OKLAHOMA THIS MORNING. ADDITIONAL SHOWERS AND STORMS ARE DEVELOPING IN WEST TEXAS AND THE TEXAS PANHANDLE WHICH COULD MOVE INTO PARTS OF OKLAHOMA AND WESTERN NORTH TEXAS LATER THIS MORNING IN ADVANCE OF A MID- LEVEL DISTURBANCE MOVING ACROSS WEST TEXAS. IF STORMS LAST THROUGH THE MORNING...THE RISK OF SEVERE WEATHER MAY BE REDUCED THIS AFTERNOON AND EVENING. HOWEVER...ADDITIONAL STORMS ARE EXPECTED TO FORM NEAR A DRYLINE BY MID AFTERNOON. THESE STORMS SHOULD IMPACT WESTERN OKLAHOMA AND ADJACENT AREAS OF NORTH TEXAS DURING THE AFTERNOON AND EVENING. THE OVERALL CONFIDENCE IN THE SCENARIO IS RATHER LOW SO CHECK BACK DURING THE DAY FOR UPDATES. .DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY... A VERY ACTIVE WEATHER PATTERN WILL REMAIN IN PLACE THROUGH THE WEEKEND. SEVERE STORMS WILL BE POSSIBLE EACH DAY...ESPECIALLY DURING THE MID AFTERNOON INTO THE LATE EVENING. AT THIS TIME...SATURDAY MAY HAVE THE GREATEST POTENTIAL FOR SEVERE WEATHER AS A STRONG STORM SYSTEM APPROACHES THE SOUTHERN PLAINS. TORNADOES WILL BE POSSIBLE WITH STORMS FRIDAY AND SATURDAY.
