NWS Lubbock, TX wrote its last area forecast discussion before the first event at Jun 26, 3:27 AM CST, 13 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LUBBOCK TX 427 AM CDT FRI JUN 26 2015 .SHORT TERM... ISOLATED TO SCATTERED SHOWERS AND STORMS CONTINUE TO DEVELOP THIS MORNING ALONG AND AHEAD OF A PRE-FRONTAL SURFACE TROUGH AND MINOR HEIGHT FALLS ALOFT. TEMPERATURES IN THE 70S AND DEWPOINTS IN THE 60S FOSTERING MLCAPE IN THE 1-1.5 KJ/KG RANGE ALONG WITH 40-50 KNOTS OF SOUTH/SOUTHEASTERLY LOW LEVEL FLOW BELOW 1000 FEET WILL LIKELY KEEP THIS TREND GOING THROUGH THE EARLY MORNING HOURS AS STORMS REALIZE UNPERTURBED MOIST/UNSTABLE INFLOW. NOT EXPECTING ANY OF THESE TO BECOME STRONG/SEVERE GIVEN A WEAKLY FORCED REGIME AND VIRTUALLY NO DEEP LAYER SHEAR TO SUSTAIN ORGANIZED UPDRAFTS. NORTHWEST FLOW WILL CONTINUE TO BUILD IN ALOFT TODAY AS UPPER TROUGHING DIGS FROM THE UPPER MIDWEST INTO THE GREAT LAKES REGION WHILE UPPER RIDGING BECOMES CENTERED FROM THE GREAT BASIN THROUGH THE SOUTHERN TO CENTRAL ROCKIES. THE FORMER FEATURE WILL DRIVE A FRONTAL BOUNDARY...CURRENTLY MOVING THROUGH SOUTHERN KANSAS AND THE OKLAHOMA PANHANDLE...INTO THE FAR SOUTHERN TEXAS PANHANDLE THIS MORNING FOLLOWED BY THE SOUTH PLAINS AND ROLLING PLAINS LATE THIS MORNING THROUGH THE AFTERNOON. WITH INCREASING INSTABILITY OWING TO DIURNAL HEATING...CONTINUED DEWPOINTS IN THE 60S...AND THE PROXIMITY OF DEEP LAYER FORCING...SHOWERS AND THUNDERSTORMS WILL DEVELOP BY MID AFTERNOON ALONG THIS FRONTAL BOUNDARY. INCREASED POPS TO MID- HIGH CHANCE EAST OF THE CAPROCK ESCARPMENT GIVEN BETTER CONVERGENCE FIELDS AND CLOSER PROXIMITY TO CYCLONIC FLOW EMANATING FROM AFOREMENTIONED GREAT LAKES UPPER TROUGH. 0-6 KM SHEAR SHOULD INCREASE TO NEAR 20 KNOTS...POTENTIALLY ALLOWING FOR A STRONG STORM OR TWO WITH CAPE VALUES IN THE 1.5-2 KJ/KG RANGE. WIND GUSTS TO 40- 50 MPH APPEAR TO BE THE MAIN THREAT GIVEN A FAIRLY DECENT SUB CLOUD DRY LAYER WHILE A LACK OF SIGNIFICANT UPDRAFT STRENGTH/ORGANIZATION AND WARMER TEMPERATURES ALOFT SHOULD INHIBIT MORE THAN PEA SIZE HAIL. STORM CHANCES SHOULD SLOWLY DRIFT SOUTH THIS EVENING/OVERNIGHT NEAR THE FRONT...WHILE LOCALES ALONG THE TEXAS/NEW MEXICO STATE LINE ALSO SEE CONVECTION ORIGINATING ACROSS THE HIGHER TERRAIN OF NEW MEXICO MOVE IN ON NORTH/NORTHWEST FLOW. .LONG TERM... MAJOR FEATURE IN THE SYNOPTIC SCALE OVER THE NEXT WEEK WILL BE A STRONG DOME OF HIGH PRESSURE TO OUR NORTHWEST OVER THE GREAT BASIN. THIS WILL SERVE AS A BLOCKING FEATURE FOR MUCH OF THE WEST. FOR US...THIS SETUP WILL PROVIDE FOR NORTHWESTERLY FLOW ALOFT TRANSITIONING TO NORTHERLY FLOW BY THE FIRST OF NEXT WEEK THEN PERHAPS BECOMING NORTHWESTERLY AGAIN BY LATE NEXT WEEK. STORMS WILL QUITE POSSIBLY BE ONGOING SATURDAY MORNING AT 12 AND PERIODS OF TSTM ACTIVITY WILL EXIST THROUGH MONDAY. THE GFS IS REMARKABLY MORE ASSERTIVE WITH POPS VS A NEARLY DRY ECM. GIVEN THE SYNOPTIC SETUP...A MODERATION/BLEND OF THE POPS SUGGESTED WOULD SEEM TO BE THE BEST APPROACH. A BIT OF A RESPITE LOOKS TO BE IN ORDER FOR TUESDAY AND WEDNESDAY AT THIS POINT WITH POPS INCREASING AGAIN LATE WEEK WITH THE RETURN OF NWRLY FLOW. WITH NORTHERLY FLOW...AFTERNOON HIGHS SHOULD NOT GET TOO WARM...PERHAPS A COUPLE OF DEGREES ABOVE NORMAL BY MID WEEK THOUGH NOTHING TO REALLY HIGHLIGHT. && .PRELIMINARY POINT TEMPS/POPS...
