DISCUSSION
PRE-HOLIDAY TRAVEL AND THANKSGIVING ITSELF WILL BE MET WITH DRY,
QUIESCENT WEATHER AND MILD DAYTIME TEMPERATURES AS BROAD HIGH
PRESSURE OVERSPREADS THE REGION THIS WEEK. IT'LL STILL BE COLD IN
THE LATE EVENINGS AND EARLY MORNINGS EACH DAY THIS WEEK AS
TEMPERATURES FALL INTO THE 20S AND 30S -- PERHAPS THE TEENS FOR COLD-
PRONE VALLEYS. SKIES WILL LIKELY BE HAZY ACROSS URBAN VALLEYS EACH
MORNING WHEN STOUT INVERSIONS EXIST, BUT PEAK AFTERNOON HEATING
SHOULD HELP DILUTE HAZE AND ANY SUBSEQUENT REDUCTIONS IN AIR QUALITY.
WEAK LOW PRESSURE WILL QUICKLY PASS BY THE PACIFIC NORTHWEST STATES
ON THE HOLIDAY, WHICH SHOULD MITIGATE HAZE AND ANY AIR QUALITY
DEGRADATIONS TOWARDS THE END OF THE WEEK. THE PASSING LOW WILL ALSO
LIKELY INCREASE CLOUD COVER FOR THE HOLIDAY, BUT TEMPERATURES WILL
BE RATHER PLEASANT WITH DAYTIME HIGHS IN THE 50S AND 60S.
A CHANGE IN THE WEATHER PATTERN MAY USHER IN A PERIOD OF COOLER,
MORE UNSETTLED CONDITIONS THIS WEEKEND INTO EARLY NEXT WEEK.
COLDER, SLIDER-TYPE SYSTEMS ARE STILL FAVORED WITH THIS PATTERN
SHIFT, BUT CONFIDENCE IS LOW ON TIMING AND IMPACT DETAILS. BE SURE
TO CHECK BACK WITH THE LATEST FORECAST AS DETAILS BECOME MORE CLEAR.
