IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.
DISCUSSION
HOT AND BREEZY CONDITIONS LIKELY TUESDAY AND WEDNESDAY, WITH NO
PRECIPITATION EXPECTED. ACCORDING TO BAILEY RAWS STATION, RH
VALUES WERE SLOWER TO DROP THAN FORECASTED IN THE EARLY
AFTERNOON, SO WILL KEEP THAT IN MIND FOR THURSDAY'S FORECAST.
A COLD FRONT WEDNESDAY EVENING WILL BRING COOLER TEMPERATURES AND
SLIGHTLY HIGHER HUMIDITIES FOR THURSDAY. MINIMUM RH IS EXPECTED TO
GET DOWN TO 18-19%, WHICH SHOULD OCCUR BY 1500 LOCAL TIME. WINDS
WILL LIKELY BE FROM THE NORTHEAST/EAST THROUGHOUT THE DAY, WITH
PERIODIC GUSTS UP TO 20 MPH, MAINLY IN THE AFTERNOON. SMOKE
DISPERSAL CONDITIONS WILL BE GOOD BY 1100 AND LAST THROUGH 1900.
IN TERMS OF SMOKE FROM OUT OF STATE, WITH NORTHWEST FLOW ALOFT
THROUGH THE END OF THE WEEK, SMOKE FROM FIRES IN WASHINGTON WILL
LIKELY BE BROUGHT INTO COLORADO TUESDAY AND WEDNESDAY. THERE IS
SOME UNCERTAINTY WITH HOW THICK THE SMOKE WILL BE, BUT IT SHOULD
CONTINUE TO EXIT OUT OF THE STATE BOTH DAYS DUE TO NORTHWEST FLOW
AT THE SURFACE. HOWEVER, IF SMOKE CONTINUES TO BE BROUGHT INTO
THE STATE ON THURSDAY, THERE IS SOME CONCERN OF IT BEING BROUGHT
INTO THE FOOTHILLS WITH THE NORTHEAST WINDS EXPECTED ON THURSDAY.
ASIDE FROM AN ISOLATED SHOWER/THUNDERSTORM ON FRIDAY (NBM 90TH
PERCENTILE IS STILL 0.05"), NO PRECIPITATION IS EXPECTED UNTIL
SATURDAY (20-25% CHANCE IN THE AFTERNOON). AFTER THAT,
PRECIPITATION/THUNDERSTORM CHANCES INCREASE BY SUNDAY AND MONDAY,
WITH THE BEST CHANCE OF WETTING RAIN MONDAY AFTERNOON. AS OF RIGHT
NOW, CURRENT FORECAST HAS 0.15" FOR ACCUMULATION FOR BOTH DAYS.
