DISCUSSION
THE UPPER TROUGH WHICH HAS BEEN OVER THE WESTERN UNITED STATES
FOR MUCH OF THE LAST WEEK WILL BEGIN TO WEAKEN AND THE FLOW WILL
BECOME MORE ZONAL OVER THE NEXT FEW DAYS.
AS A RESULT, TEMPERATURES WILL BEGIN TO WARM, AND TODAY WILL BE
THE LAST DAY OF THE BELOW NORMAL TEMPERATURES. ADDITIONALLY,
THERE WILL BE ONE LAST BIT OF SHORTWAVE ENERGY MOVING THROUGH
TODAY, WHICH WILL HELP ENHANCE THE TROUGH BEFORE IT BEGINS TO
WEAKEN THURSDAY AND THE ZONAL FLOW PERMEATES FRIDAY AND
SATURDAY.
BY SUNDAY, THE FLOW WILL BECOME MORE SOUTHWESTERLY INTO EARLY
NEXT WEEK AND THIS IS WHEN IT IS POSSIBLE FOR ANY SHORT WAVES
TO BRING SHOWER OR THUNDERSTORM CHANCES, MAINLY TO THE
MOUNTAINS, BUT OVERALL IT SHOULD REMAIN DRY.
ADDITIONALLY, HIGH PRESSURE WILL BEGIN TO BUILD OVER THE FOUR
CORNERS AND HOW STRONGLY THIS RIDGE BUILDS AND HOW IT INTERACTS
WITH OTHER WEATHER FEATURES OVER THE COURSE OF THE NEXT WEEK
WILL DETERMINE HOW HOT WE GET AND ULTIMATELY IF ANY TRIPLE
DIGITS ARE IN OUR NEAR FUTURE. BUT A WARMING TREND THROUGH THE
HOLIDAY WEEKEND AND INTO EARLY NEXT WEEK IS DEFINITELY IN STORE.
BY MONDAY AND TUESDAY, HIGHS IN THE LOW TO MID 90S ACROSS THE
COLUMBIA BASIN AND OTHER LOW ELEVATION AREAS LOOK TO BE LIKELY.
WINDS WILL BE GUSTY AGAIN TODAY, MAINLY ACROSS THE KITTITAS
VALLEY, SIMCOE HIGHLANDS, PORTIONS OF THE GORGE AND NORTH-
CENTRAL OREGON, THOUGH WINDS SHOULDN'T BE AS STRONG AS THEY HAVE
BEEN. GUSTS STILL COULD REACH 25 TO 35 MPH WITH LOCALLY HIGHER
VALUES. TODAY SHOULD BE THE LAST REALLY BREEZY DAY.
WIND GUSTS DO CONTINUE IN THE 20 TO 30 MPH RANGE OVER THE NEXT
FEW DAYS IN THE KITTITAS VALLEY, COLUMBIA GORGE, BASIN AND
SIMCOE HIGHLANDS. BY SATURDAY, THESE GUSTS COUPLED WITH RH
VALUES IN THE TEENS WILL LEAD TO ENHANCED FIRE WEATHER CONCERNS
AND WE WILL KEEP AN EYE ON HOW THINGS DEVELOP OVER THE NEXT FEW
DAYS FOR ANY POTENTIAL FIRE WEATHER HEADLINES.
AVIATION /12Z TAFS THROUGH 12Z THURSDAY/
VFR CONDITIONS ARE EXPECTED THROUGH THE TAF PERIOD. WINDS WILL
GUST AROUND 20 KTS AT MOST SITES THROUGH THE AFTERNOON AND EARLY
EVENING HOURS AND 25 TO 30 KTS AT DLS.
