AN UPPER LEVEL LOW PRESSURE SYSTEM AND ASSOCIATED COLD FRONT WILL SWEEP THROUGH THE DESERT SOUTHWEST TONIGHT AND THURSDAY MORNING. THIS SYSTEM WILL PROVIDE FOR VERY WINDY CONDITIONS TONIGHT...

THIS WILL PUSH SEVERAL NEGATIVE-TILT TROUGHS TOWARDS THE REGION OVER THE NEXT WEEK...THE STRONGEST OF WHICH LOOKS LIKE IT WILL ARRIVE SUNDAY AFTERNOON INTO MONDAY AND ANOTHER ON TUESDAY. OF COURSE...TIMING REMAINS AN ISSUE...SO EXTENDED POP/WX GRIDS ARE KIND OF BROAD-BRUSHED WITH LOW TO MEDIUM GRADE CHANCE VALUES. ALSO...AM INCLUDING SOME HIGHER TERRAIN SNOW DURING THE EXTENDED...IN BOTH JTNP AND AZZ024. && .PSR...WATCHES/WARNINGS/ADVISORIES... AZ...WIND ADVISORY CO RIVER ZONES 20 AND 25 TIL 19/11Z.
