DISCUSSION
THE UPPER TROUGH THAT HAD BEEN OVER THE WESTERN STATES WILL
SLOWLY WEAKEN TODAY. THE FLOW IS EXPECTED TO BECOME MORE
WESTERLY FRIDAY INTO SATURDAY AND SOUTHWESTERLY BY SUNDAY.
WITH THIS CHANGE IN FLOW, TEMPERATURES ARE EXPECTED TO WARM AND
WILL BE PUSHING 90 IN THE LOWER ELEVATIONS BY SATURDAY AND WELL
INTO THE 90S BY MONDAY. AFTER MUCH OF THE LAST WEEK SEEING
BELOW NORMAL TEMPERATURES, BY EARLY NEXT WEEK TEMPERATURES WILL
AVERAGE 5 TO 10 DEGREES ABOVE NORMAL. BY MONDAY AND TUESDAY,
HEATRISK WILL BE MODERATE ACROSS MUCH OF THE COLUMBIA BASIN,
YAKIMA AND KITTITAS VALLEYS AND PORTIONS OF THE COLUMBIA GORGE.
IN THE SOUTHWEST FLOW ON MONDAY, THERE WILL BE SOME LOW (<20
PERCENT) SHOWER AND EVEN LOWER THUNDERSTORM CHANCES, MAINLY OVER
THE CENTRAL AND EASTERN MOUNTAINS OF OREGON.
OTHERWISE, THE WEEK LOOKS RELATIVELY DRY.
WITH THE WARMING TEMPERATURES, HUMIDITY VALUES WILL DECREASE INTO
THE TEENS AND WITH THE DIURNAL BREEZES, ESPECIALLY ON SATURDAY THERE
WILL BE ENHANCED FIRE WEATHER CONCERNS, ESPECIALLY FOR THE COLUMBIA
BASIN AND KITTITAS VALLEY. WILL NEED TO MONITOR THESE AREAS FOR ANY
HEADLINES MOVING FORWARD.

HOURS AT ALL TAF SITES. WINDS WILL BE DIURNALLY BREEZY AT DLS WITH
