VALLE

.LONG TERM...THU NIGHT THROUGH NEXT MON NIGHT. LONGWAVE AT 500MB
CONTINUES TO INDICATE THE TRANSITION FROM ZONAL TO A WEST COAST
UPPER LEVEL RIDGE AND GREAT PLAINS TROUGH.  THIS SHOULD KEEP THINGS
QUIET...COOL...AND RELATIVELY DRY DURING THE EXTENDED FORECAST. DO
NOT FORESEE ANY ANY MAJOR FRONTS...THE ONLY SIGNIFICANT THING MAY
BE SOME DAYS WITH ENOUGH MOISTURE AND DIURNAL INSTABILITY TO
GENERATE THUNDERSTORMS AND SHOWERS DURING THE AFTERNOON AND
EVENING. THE ZONAL FLOW WILL ALLOW STRONGER THAN NORMAL WINDS FOR
THE AFTERNOON AND EVENINGS AS WELL. TOWARDS THE END OF THE
FORECAST...THE ECMWF BRINGS IN THE MOST SIGNIFICANT TROUGH OF THE
PERIOD...BUT THE GFS HAS NEARLY NOTHING. EXPECT STRONG DIURNAL
TEMPERATURE SWINGS UNDER THE MAINLY CLEAR SKIES WITH TEMPERATURES
RUNNING ABOVE NORMAL IN THE CLEAR SKIES. MESSICK

&&

.AVIATION...HIGH PRESSURE KEEPING CIGS AND VSBYS UNLIMITED. ONLY
LIGHT WIND THIS AFTERNOON AND EVENING. MESSICK

&&

.PIH WATCHES/WARNINGS/ADVISORIES...
NONE.
