SHORT TERM...TONIGHT THROUGH FRIDAY.

THIS MORNINGS SNOW HAS MOVED AWAY FROM THE AREA LEAVING MAINLY DRY
CONDITIONS FOR THE AFTERNOON. THE NAM IS TRYING TO PRODUCE A FEW
ISOLATED SNOW SHOWERS ASSOCIATED WITH AN UPPER LEVEL SPEED MAX FOR
TONIGHT DEVELOP OFF THE CENTRAL MOUNTAINS DRIFTING INTO THE SNAKE
PLAIN. AM SEEING SOME INDICATIONS OF THIS TRYING TO DEVELOP BASED
UPON RADAR/SATELLITE TRENDS. HOWEVER GIVEN THE AMOUNT OF DRY AIR
OVER THE REGION ANY AMOUNTS WILL BE NEGLIGIBLE. OTHERWISE HIGH
PRESSURE WILL PRODUCE DRY WEATHER ACROSS THE REGION FOR THE REST OF
THE SHORT TERM. VERY COLD TEMPS FOR TONIGHT AND WEDNESDAY...WITH
TEMPS MODERATING CLOSER TO NORMAL BY THURSDAY.

VALLE

LONG TERM...FRIDAY NIGHT THROUGH TUESDAY NIGHT. HIGH PRESSURE
RIDGING WILL DOMINATE THROUGH THE PERIOD BRINGING DRY CONDITIONS AND
WARMER THAN NORMAL TEMPERATURES. BOTH MODELS HAVE DROPPED THE WEAK
SYSTEM MOVING THROUGH FRIDAY NIGHT INTO SATURDAY.
WYATT

AVIATION...VFR CONDITIONS ARE AT ALL TAF SITES THIS AFTERNOON.
EXPECT VFR CIGS THROUGH EARLY EVENING FOR ALL TAF SITES AS HIGH
PRESSURE RIDGING IS STARTING TO BUILD INTO THE AREA BEHIND AN
EXITING SYSTEM. MODELS ARE SHOWING NEAR MVFR CIGS FOR KIDA...KPIH
AND KIDA BRIEFLY LATE TONIGHT INTO TOMORROW MORNING. IF MVFR
STRATUS CIGS SET UP THEY SHOULD DISSIPATE BY LATE TOMORROW MORNING.
