.SHORT TERM...

AN UPPER LOW CONTINUES TO PULL AWAY WITH DRIER AIR ALOFT BEGINNING
TO FILTER ACROSS THE REGION. ALTHOUGH MOISTURE WILL BE DECREASING
THIS AFTERNOON, LESS SKY COVER AND BETTER SURFACE HEATING SHOULD AID
IN INCREASED LOW LEVEL INSTABILITY TO GENERATE A FEW SHOWERS AND
ISOLATED THUNDERSTORMS. THE MOST FAVORED AREAS WILL BE COINCIDENT
WHERE THERE IS STILL SOME LINGERING LOW LEVEL MOISTURE, MAINLY IN
THE VICINITY OF THE LASSEN CONVERGENCE ZONE ACROSS NORTHERN LASSEN
COUNTY THROUGH NORTHERN WASHOE COUNTY. MONO, MINERAL AND CHURCHILL
COUNITES WILL ALSO CHANCES FOR SHOWERS AND ISOLATED STORMS. HIGH
TEMPERATURES TODAY WILL REACH INTO THE LOWER 80S ACROSS WESTERN
NEVADA WITH LOWER TO MID 70S EXPECTED ACROSS THE SIERRA AND FAR
NORTHEASTERN CALIFORNIA.

UPPER LEVEL RIDGING WILL THEN BUILD ACROSS THE REGION FOR THURSDAY
AND FRIDAY WITH ONLY SLIGHT CHANCES FOR A POP-UP SHOWER OR STORM
EXPECTED AS INSTABILITY DECREASES WITH WARMING ALOFT AND DRIER AIR
BECOMING ESTABLISHED AT MIDLEVELS. MAIN STORY WILL BE THE WARM
TEMPERATURES WITH HIGH TEMPERATURES WARMING INTO THE MID AND UPPER
80S ACROSS WESTERN NEVADA WITH WARMER VALLEYS ACROSS THE BASIN AND
RANGE NEARING THE 90 DEGREE MARK BY FRIDAY. ACROSS THE SIERRA HIGHS
WILL REACH INTO THE MID TO UPPER 70S. FUENTES


.LONG TERM...SATURDAY THROUGH TUESDAY...
THE PATTERN WILL BE IN A TRANSITION FROM THE RIDGE FRIDAY TO A
SOMEWHAT DEEP TROUGH BY MONDAY. TEMPS WILL REMAIN ABOVE NORMAL FOR
THE WEEKEND WITH WINDS INCREASING INTO SUNDAY AS THE TROUGH
APPROACHES. SUNDAY WILL BE BREEZY AS H7 WINDS INCREASE TO 20-25
KTS. THERE IS ALSO A SMALL THREAT FOR THUNDERSTORMS LATE SUNDAY
AFTERNOON INTO THE EVENING AHEAD OF THE COLD FRONT.

SUNDAY NIGHT INTO MONDAY, THE COLD FRONT WILL MOVE THROUGH WITH A
SLIGHT CHANCE OF THUNDERSTORMS. WHILE THE BEST MOISTURE LOOKS TO
REMAIN NORTH INTO OREGON, THE FORCING WITH THE TROUGH WILL BE STRONG
AS IT COMES IN NEGATIVELY TILTED. BEHIND THE FRONT, A COUPLE SHORT
WAVES WILL MOVE THROUGH AND KEEP THE SHOWER THREAT GOING AT LEAST
NORTH OF I-80. WINDS WILL ALSO BE BREEZY MONDAY BEHIND THE FRONT
BEFORE RELAXING TUESDAY. TEMPERATURES WILL ALSO COOL BACK CLOSE TO
AVERAGE FOR EARLY JUNE FOR MONDAY/TUESDAY. WALLMANN
