NWS Lubbock, TX wrote its last area forecast discussion before the first event at Mar 21, 2:48 PM CST, 4 hours 21 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LUBBOCK TX 348 PM CDT WED MAR 21 2007 .SHORT TERM... THE POTENTIAL FOR ISOLATED STORMS REMAINS THE FOCUS OF ATTENTION FOR THIS UPDATE. THE MOISTURE GRADIENT APPEARS TO BE TIGHTENING OVER THE FA THIS AFTERNOON...AS SHALLOW MOISTURE CONTINUES TO MIX ON THE CAPROCK. SATELLITE/RADAR TRENDS SUGGEST MODERATE FORCING/DEEP LIFT SPREADING OVER MUCH OF EASTERN NEW MEXICO ATTM...WITH MID LEVEL ACCUS/VIRGA SHOWERS DEVELOPING IN THE DRY AIR WEST OF THE DRYLINE. A 20Z SOUNDING FROM REESE CENTER /COURTESY THE WEST TEXAS MESONET/ INDICATED A WEAKENING CAPPING INVERSION WITH MODERATE INSTABILITY. SINCE ASCENT WILL CONTINUE TO INCREASE THROUGH THE EVENING AS THE INFLUENCE AN INCOMING SHORTWAVE TROUGH/WIND MAX INCREASES...ISOLATED STORMS SHOULD EMERGE FROM THE MID LEVEL CONVECTION OUT WEST AS SAID FORCING OVERSPREADS BETTER MOISTURE. ANY STORMS THAT INITIATE...WILL PRESENT A THREAT OF SEVERE WIND/HAIL. DEEPLY MIXED PBLS WILL PRESENT A THREAT OF DOWNBURSTS. THE CHANCE OF CONVECTION WILL INCREASE THROUGH EARLY THURSDAY...AS WELL DEFINED BAROCLINIC LEAF-LIKE FEATURE NOW SEEN IN VAPOR IMAGERY OVER NORTHWESTERN MEXICO PROPAGATES TOWARD THE REGION. INCREASED FORCING FOR ASCENT IN DIFFLUENT FLOW WILL PROVIDE A GOOD CHANCE OF RAIN/STORMS BY MIDDAY THURSDAY. HOWEVER...INSTABILITY APPEARS TO BE SOMEWHAT LIMITED...THUS PERHAPS A LESSER THREAT OF SEVERE. .LONG TERM... FOCUS OF FORECAST WAS ON RAIN CHANCES AND SEVERE WEATHER THREAT WITH APPROACH OF STORM SYSTEM TO CLOSE OUT THE WORK WEEK AND HEAD INTO THE WEEKEND. MODELS ARE IN GOOD AGREEMENT THAT JET ENERGY DIVING DOWN THE BACK SIDE OF UPPER LOW ACROSS SOUTHERN CA WILL CAUSE STORM TO CONTINUE TO DIG SOUTH OFF THE BAJA BEFORE MOVING MORE EASTWARD BY LATE THURSDAY INTO FRIDAY. THEN...AS IS OFTEN THE CASE WITH A CUTOFF SYSTEM...MODELS DIVERGE WITH THE SPEED AND TRACK OF SYSTEM ALTHOUGH THERE IS A GENERAL CONSENSUS THAT IT WILL MOVE TO THE NORTHEAST...PASSING THROUGH NEW MEXICO SATURDAY. ECMWF IS FARTHEST WEST AND QUICKEST WITH THE LOW...WITH WRF-NMM AND DGEX SLOWEST AND FARTHEST SOUTH. HAVE CONTINUED WITH THE MIDDLE OF THE ROAD SOLUTIONS. THIS WILL BRING THE BEST UPPER-LEVEL SUPPORT ACROSS THE CWFA LATE FRIDAY INTO SATURDAY. GIVEN ABUNDANT PACIFIC AND GULF MOISTURE IN PLACE /WITH PWATS AROUND 1.00 INCH+ PROGGED/ THIS APPEARS TO BE THE BEST WINDOW FOR HEAVY RAINFALL...ALTHOUGH UNCERTAINTY IN TRACK STILL MAKE EXACT LOCATION OF HEAVIEST RAINFALL TOUGH TO PINPOINT. NONETHELESS...HAVE ADDED A MENTION OF HEAVY RAIN IN THE GRIDS FRIDAY NIGHT AND SATURDAY MORNING SINCE SOME LOCATION COULD RECEIVE A COUPLE OF INCHES. BEFORE THEN...ONE OR MORE SHORTWAVES WILL LIKELY ROTATE AROUND THE UPPER LOW...BRINGING BETTER CHANCES OF SHOWERS/STORMS WITH THEIR PASSAGE. HOWEVER...TIMING/RESOLUTION OF THESE WAVES ARE DIFFICULT. STILL...DOES APPEAR ONE WAVE MAY BE EXITING THE REGION THURSDAY EVENING/FRIDAY MORNING...LEAVING A POSSIBLE LULL IN ACTIVITY. RAIN CHANCES WILL THEN BE ON THE INCREASE FRIDAY AS INCREASINGLY DIFFLUENT FLOW ADVANCES TOWARD THE REGION. ADDITIONALLY...DEEP LAYER SHEAR WILL REMAIN SUFFICIENT FOR ORGANIZED CONVECTION FRIDAY. HOWEVER...THERE IS UNCERTAINTY IN THE EXACT AMOUNT OF INSTABILITY WITH EXTENSIVE CLOUD COVER AND POSSIBLE PRECIPITATION ONGOING. THUS..CONFIDENCE IN WIDESPREAD SEVERE CONVECTION NOT HIGH AND HAVE LEFT OUT OF GRIDS FOR NOW. STORM SYSTEM SHOULD FINALLY BE EXITING WEST TEXAS SUNDAY...WITH RESIDUAL UPPER TROUGH SWINGING EAST OF THE AREA BY LATE SUNDAY. HAVE EXTENDED SLIGHT CHANCE OF STORMS ACROSS THE EASTERN ZONES THROUGH SUNDAY AFTERNOON. EXPECT RELATIVELY QUIET AND WARM CONDITIONS TO BEGIN THE NEXT WORK WEEK...WITH RETURNING LOW-LEVEL MOISTURE BY THE MIDDLE OF THE WEEK. && .PRELIMINARY POINT TEMPS/POPS...
