AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AMARILLO TX 340 PM CDT SAT JUN 19 2004 .DISCUSSION... OUTFLOW BOUNDARY FROM CONVECTION OVERNIGHT CONTINUES TO SAG SLOWLY SOUTWESTWARD...ALTHOUGH IT APPEARS TO HAVE BECOME NEARLY STATIONARY IN LATEST VISIBLE SATELLITE LOOP. AMPLE BL MOISTURE HAS ALLOWED MOSTLY CLOUDY SKIES TO PREVAIL...LIMITING INSOLATION SOMEWHAT. HOWEVER...SKIES ARE CLEAR ACROSS THE EASTERN PORTIONS OF NM AND STORMS ALREADY ARE FIRING IN THE MTNS THEREFORE HAVE SWITCHED POP GRIDS AROUND TO HAVE CHANCE IN THE WEST TAPERING TO SLIGHT CHANCE IN THE EAST WHERE INSTABILITY IS LIMITED SOMEWHAT. TEMPS WILL BE TRICKY THE NEXT COUPLE OF DAYS. SUNDAY SHOULD BE WARMER WITH SOUTHWESTERLY WINDS DEVELOPING IN RESPONSE TO SFC LOW OVER SE/SC CO. BELIEVE THAT THE ETA IS OVERDOING DRYING OF ATMOSPHERE ESPECIALLY WITH MOISTURE LEVELS IN THE SOIL AS HIGH AS THEY ARE IN AREAS...THUS COMPROMISED WITH THE GFS. TEMPS WILL WARM BACK INTO THE 90S BEFORE ANOTHER FRONT PUSHES INTO THE AREA MON MORN. THIS SHOULD STALL OUT AND BEGIN ANOTHER ROUND OF PRECIPITATION FOR THE FIRST PART OF NEXT WEEK. AGAIN...BEST CHANCES WILL BE DETERMINED BY LOCATION FRONTAL BAROCLINIC ZONE ENHANCED BY OUTFLOW FROM CONVECTION. HEAVY RAIN COULD AGAIN BE A POSSIBILITY WITH EASTERLY UPSLOPE FLOW HOLDING DEEP MOISTURE OVER THE REGION. NO MAJOR CHANGES TO GRIDS/FCST IN SHORT TERM OTHER THAN TO TWEAK POPS...WINDS...AND TEMPS FOR FIRST 3 DAYS. BEYOND TUESDAY...UPPER LEVEL PATTERN BEGINS TO SHIFT TOWARDS A NORTHWESTERLY FLOW WHICH WOULD FAVOR CONVECTION DRIFTING OFF THE MOUNTAINS INTO THE REGION. 20S IN THE FORECAST ARE SUFFICIENT FOR NOW AS ENSEMBLES ARE STILL EVENLY SPLIT...BUT UKMET AND ECMWF ALSO HINT AT NWLY FLOW. EXTENDED GRIDS/FCST LOOK GOOD SO NO CHANGES. FCSTID = JORDAN && .PRELIMINARY POINT TEMPS/POPS...
