Area forecast discussion, Apr 8, 3:33 PM CDT, 4 hours 23 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LUBBOCK TX 301 PM CDT THU APR 8 2004 .SHORT TERM... POTENT UPPER LEVEL LOW PRESSURE SYSTEM CONTINUING TO DRIVE EASTWARD AND NOW CROSSING CENTRAL NEW MEXICO. SYSTEM CONTINUES TO BE PROLIFIC LIGHTNING PRODUCER...WITH CONSIDERABLE ADTIVITY DEVELOPING ALONG THE STRONG POTENTIAL VORTICITY LOBES. AND ACTIVITY LATELY HAS BEGUN TO INTERACT WITH THE HIGHER SURFACE MOISTURE AND MARGINAL CAPES LYING OVER THE SOUTHERN PLAINS. ENOUGH INSTABILITY AND SHEAR FOR THE STORM PREDICTION CENTER TO ISSUE A SSEVERE THUNDERSTORM WATCH EARLY THIS EVENING OVER THE WESTERN HALF OF THE AREA. THUNDERSTORMS SHOULD INIITIALLY FEED OFF THE SURFACE HEATING AND CAPES...AND PROBABLY USE THAT MOSTLY UP BY SUNSET...BUT BY THEN A LOW LEVEL JET WILL BECOME ORGANIZED ACROSS WEST TEXAS. AND THIS IS EXPECTED TO FEED THUNDERSTORMS MOVING THROUGH CENTRAL SOUTH PLAINS LATER THIS EVENING...AND INTO EASTERN ZONES OVERNIGHT. SOME POTENTIAL FOR LOCALLIZED FLOODING PROBLEMS IF CONVECTION DOES BACK-BUILD ALONG LOW LEVEL JET INTO THE INCREASING POTENTIAL TEMPERATURES...BUT AREA TO BE IMPACTED UNCERTAIN AND LIKELY SMALL. CAN PROBABLY DEAL WITH THIS SITUATION USING FLOOD ADVISORIES. WE DID SLIGHTLY INCREASE PRECIPITATION CHANCES WESTERN ZONES ON VERGE OF THUNDERSTORMS NOW... OTHERWISE PREVIOUS FORECAST ELEMENTS WERE VERY GOOD WITH ONLY SLIGHT CHANGES MAINLY TO WIND AND DEWPOINT FIELDS. SYSTEM WILL PASS AREA EARLY FRIDAY WITH IMPROVING CONDITIONS AND DRIER WEST-SOUTHWEST FLOW TAKING OVER ON FRIDAY. THIS WILL GIVE ANOTHER NEEDED BREAK IN BETWEEN THE NEXT ROUND OF DISTURBANCES THAT WILL ALREADY BE APPROACHING THE AREA BY LATE IN THE DAY FRIDAY. .LONG TERM... THE NEXT SERIES OF IMPULSES THAT WILL AFFECT THE SOUTH PLAINS ARE CURRENTLY DROPPING SOUTHEAST THROUGH THE NORTHERN GREAT BASIN AND NORTHERN ROCKIES. THESE ARE EXPECTED TO CARVE OUT A FAIRLY SHARP AND COLD TROF OVER TYHE SOUTHERN ROCKIES INTO THE SONORAN DESERT OF NORTH-CENTRAL MEXICO OVER THE WEEKEND. THIS WILL ALLOW AT LEAST TWO DISTINCT SURFACE COLD FRONTS WITH COLDER CANADIAN AIR TO SPREAD INTO THE AREA. FIRST COLD FRONT WILL ARRIVE EARLY SATURDAY...AND THEN A REINFORCEMENT IS EXPECTED LATE IN THE WEEKEND OR EARLY MONDAY MORNING. IN SPITE OF INLAND TRACK OF SYSTEMS...THEY DO NOT APPEAR TO BE TOTALLY MOISTURE STARVED...AND WITH EXPECTED DYNAMIC LIFT ARE STILL POTENT ENOUGH FOR MENTION OF LOW-END PRECIPITATION CHANCES FROM TIME TO TIME THROUGH MONDAY...AND EVEN MIXING OR CHANGING TO SNOW ACROSS NORTHWEST AND NORTH CENTRAL ZONES BY END OF THE WEEKEND. FREEZING TEMPERATURE PROSPECTS ARE ALSO THERE...ESPECIALLY BY MONDAY...AS CLOUD COVER AND WIND AS WELL AS VERY MOIST AND RELATIVELY WARM GROUND IS LIKELY TO LIMIT COOLING INITIALLY...BUT STRONGER COLD ADVECTION EARLY MONDAY MAY BRING NEAR FREEZING CONDITIONS TO AT LEAST NORTHERN ZONES. THIS WILL NEED CLOSER MONITORING OVER THE NEXT COUPLE OF DAYS. PATTERN THEN APPEARS READY TO TAKE A DISTINCTLY WARMER TURN WITH RIDGING OVER THE WESTERN STATES TRANSLATING INTO THE ROCKIES AND HIGH PLAINS...WITH ABOVE NORMAL TEMPERATURES LIKELY MIDDLE OF NEXT WEEK. INCREASING SOUTHWEST FLOW MAY LIE JUST BEYOND...BY END OF NEXT WEEK. MCQUEEN && .PRELIMINARY POINT TEMPS/POPS...
