AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 309 PM CDT WED APR 23 2014 .DISCUSSION... BUSY FORECAST THROUGH THIS WEEKEND...WITH SEVERE STORMS LIKELY TODAY/TONIGHT...SATURDAY...AND PERHAPS SUNDAY. DRYLINE IS CURRENTLY LOCATED EAST OF AMARILLO SOUTHWARD TO NEAR BIG SPRING TX. CU FIELD BECOMING MORE ENHANCED NEAR SNYDER TX NOW...AND EXPECT INITIAL DEEP CONVECTION THERE WHERE CURRENT MESO ANALYSIS INDICATES HIGHEST INSTABILITY AND LOWEST CIN ALONG THE DRYLINE. ADDITIONAL CU CAN BE SEEN JUST EAST AND NE OF AMA AS WELL. WILL KEEP THIS DISCUSSION SHORT SINCE AT LEAST A SEVERE WATCH WILL LIKELY BE ISSUED VERY SOON FOR WESTERN OK/N TX. MAIN THREAT (LARGE HAIL NEAR TENNIS BALLS AND DAMAGING WINDS OVER 70 MPH) WILL REMAIN THERE THROUGH THE EARLY EVENING AND THEN PERHAPS SHIFT EASTWARD INTO CENTRAL OK DURING THE LATE EVENING HOURS (SMALLER HAIL BUT STILL A DAMAGING WIND THREAT). POPS SHOULD QUICKLY DECREASE EARLY TOMORROW MORNING AS COLD FRONT PUSHES THROUGH THE AREA. EXPECT SOME FAIRLY STRONG WINDS (25 TO 35 MPH) BEHIND THE FRONT SO AN ADVISORY MAY EVENTUALLY BE NEEDED. NOT MUCH GOING ON BY THURSDAY AFTERNOON/EVE AS WINDS BEGIN TO DECREASE WITH ONSET OF SFC HIGH. BY FRIDAY AFTERNOON/EVE ANOTHER LEE LOW WILL DEVELOP NEAR SE CO AND MOISTURE WILL START TO RETURN UNDER THE INFLUENCE OF SSE FLOW. DIFFUSE DRYLINE MAY SETUP ALONG TX PANHANDLE/OK BORDER...BUT WILL LEAVE ANY MENTION OF THUNDER OUT FOR NOW AS SHORTWAVE RIDGING MOVES OVERHEAD. LOW POPS MAY NEED TO BE INTRODUCED NEAR SW OK/W N TX WHERE CAP MAY ERODE AND ENOUGH SFC CONVERGENCE COULD PROVIDE LIFT FOR A COUPLE OF STORMS TO DEVELOP. BY SATURDAY MORNING A POTENT UPPER TROUGH WILL MOVE INTO THE SOCAL REGION...AND THEN TO NEAR OR JUST WEST OF THE 4 CORNERS BY 00Z SUN. EXPECT SFC DEWPOINTS TO MAKE IT INTO THE LOW TO MID 60S AHEAD OF THIS FEATURE LATE SAT AFTERNOON. RAPID HEIGHT FALLS THROUGH SATURDAY EVENING...PLENTY OF INSTABILITY...AND SUFFICIENT DEEP LAYER SHEAR WILL LIKELY RESULT IN A MORE SIGNIFICANT SEVERE WX THREAT ALONG AND WEST OF I35. THE THREAT WILL THEN SHIFT EASTWARD SUNDAY AFTERNOON AND EVENING WITH THE CLOSED LOW WITH MOST OF THE COVERAGE JUST EAST OF OUR FA. HOWEVER...WILL KEEP CHC POPS IN FOR THE EASTERN ZONES SUNDAY AS THE ECMWF AND GEMNH SOLUTIONS ARE SLOWER. && .PRELIMINARY POINT TEMPS/POPS...
