SHORT TERM...TONIGHT AND FRIDAY  
DESPITE MEMORIAL DAY QUICKLY APPROACHING, IT'S BEEN A CLOUDY,  
CHILLY, WINDY AND FOR SOME, SNOWY, DAY ACROSS EASTERN IDAHO.  
AFTERNOON SATELLITE IMAGERY SHOWS AN UPPER LOW MOVING INTO CENTRAL  
WYOMING BUT CLOUDS AND MOISTURE ASSOCIATED WITH THIS FEATURE REMAIN  
IN PLACE ACROSS EASTERN PORTIONS OF THE FORECAST AREA. DID SEE SOME  
LIGHT SNOWFALL FROM AROUND REXBURG UP THROUGH ISLAND PARK THIS  
MORNING AND TEMPERATURES HAVE WARMED UP ENOUGH IN THE LOWER LEVELS  
FOR A CHANGEOVER TO RAIN BUT LIGHT SNOW STILL CONTINUES IN THE  
HIGHER TERRAIN AND WILL CONTINUE INTO THE MID EVENING. WINDS REMAIN  
BREEZY ACROSS MUCH OF THE AREA AND HAVE EXTENDED THE LAKE WIND  
ADVISORY FOR AF RESERVOIR FOR A FEW MORE HOURS GIVEN THE ONGOING  
CONDITIONS. AS THE LOW CONTINUES TO PUSH EAST, SHOULD CONTINUE TO  
SEE GRADUAL CLEARING THROUGHOUT THE OVERNIGHT ALLOWING TEMPERATURES  
TO DROP ONCE AGAIN CLOSE TO THE FREEZING MARK IN THE LOWER  
ELEVATIONS AND INTO THE 20S ACROSS THE HIGH COUNTRY. ANOTHER FROST  
ADVISORY HAS BEEN ISSUED ACCORDINGLY FOR THE GROWING REGIONS.  
 
FRIDAY LOOKS MOSTLY DRY AS WE WILL SEE A BIT OF A BREAK IN BETWEEN  
WEATHER SYSTEMS BEFORE THINGS BECOME MORE UNSETTLED ONCE AGAIN ON  
SATURDAY. TEMPS WILL REMAIN ON THE COOLER SIDE OF NORMAL BUT SHOULD  
BE SOME 10-15 DEGREES WARMER THAN THU HIGH TEMPERATURES. MOSTLY  
CLEAR SKIES EARLY WILL GRADUALLY GIVE WAY TO INCREASING CLOUDS AS WE  
START TO FEEL THE INFLUENCE OF OUR NEXT WEATHER SYSTEM. COULD SEE A  
FEW ISOLATED SHOWERS UP ALONG THE MONTANA DIVIDE AND INTO THE  
CENTRAL MOUNTAINS TOMORROW BUT THESE LOOK TO BE PRETTY ISOLATED.  
MCKAUGHAN  
 
LONG TERM...SATURDAY THROUGH THURSDAY  
WE WILL START OUT THE MEMORIAL DAY WEEKEND ON THE WET AND COOL  
SIDE. IT LOOKS FAIRLY SHOWERY, WITH A FEW AFTERNOON THUNDERSTORMS  
MIXED ON ON SATURDAY. HIGH TEMPERATURES BARELY HIT 60-65 FOR THE  
VALLEYS, WITH MUCH COLDER CONDITIONS IF YOU ARE HEADED INTO THE  
HIGHER MOUNTAINS. IT WILL BE BREEZY, SO IT WILL FEEL EVEN COOLER  
THAN ACTUAL TEMPERATURES. WE WILL CLEAR OUT ON SUNDAY, LEAVING  
MEMORIAL DAY ITSELF DRY IT APPEARS. WE MIGHT SEE A STRAY SHOWER  
OVER THE MOUNTAINS, BUT THE CHANCE IS WELL BELOW 10%. TEMPERATURES  
BY MONDAY PUSH BACK INTO THE 70S FOR THE VALLEYS AND 50S/60S FOR  
THE MOUNTAINS. PRECIPITATION- WISE, DON'T EXPECT TOO MUCH OUTSIDE  
SOME OF THE HIGHER ELEVATIONS, WHERE 0.10-0.33" IS POSSIBLE. SNOW  
LEVELS SHOULDN'T GET TERRIBLY LOW, BUT ENOUGH THAT AN INCH OR TWO  
IS POSSIBLE...ESPECIALLY FOR HIGHEST RIDGES AND PEAKS. HIGH  
PRESSURE EARLY NEXT WEEK QUICKLY SHIFTS EAST OF THE DIVIDE,  
OPENING THE DOOR UP FOR A RETURN OF PRECIPITATION HEADING INTO THE  
MIDDLE OF NEXT WEEK. WE WILL REMAIN ON THE WARM SIDE OF THE  
WEATHER PATTERN...WHICH FOR NOW MEANS NO IMMEDIATE RETURN TO  
TEMPERATURES EXPERIENCED WITH RECENT STORMS ACROSS THE STATE.  
KEYES  
 
AVIATION...

IMPACTING BYI, PIH AND IDA SHOULD BE GONE BY LATE EVENING. WE SHOULD  
SEE A BREAK UNTIL LATER FRIDAY. LOOK FOR VFR OVERNIGHT AND MOST OF  
TOMORROW. KEYES
