...CHANGE TO COOLER WEATHER LATER THIS WEEK...

AFTER A MILD STRETCH OF WEATHER, NORTHWEST OREGON AND SOUTHWEST
WASHINGTON WILL SEE THEIR COLDEST TEMPERATURES SO FAR THIS FALL
LATER THIS WEEK. THE FIRST TASTE OF COLD TEMPERATURES WILL ARRIVE
WEDNESDAY NIGHT WITH OVERNIGHT LOWS DROPPING INTO THE 30S. THIS
WILL BE COLD ENOUGH TO SUPPORT PATCHY FROST ACROSS THE INTERIOR
LOWLANDS, PARTICULARLY IN OUR NORMALLY COLDER VALLEY LOCATIONS
SUCH AS YACOLT, BATTLE GROUND, VERNONIA, HILLSBORO, EUGENE,
LEBANON, SWEET HOME, SILVERTON AND MOLALLA.

ANOTHER FRONT WILL PUSH EVEN COLDER AIR INTO THE REGION ON FRIDAY
AND SATURDAY. THIS WILL BRING SNOW LEVELS DOWN INTO THE 1500 TO
3000 FEET RANGE LATE FRIDAY NIGHT INTO SATURDAY. IT IS STILL TOO
EARLY TO PREDICT EXACT SNOW AMOUNTS YET, BUT THERE IS POTENTIAL
FOR 3 TO 6 INCHES OF SNOW ACROSS THE CASCADES, PARTICULARLY ABOVE
3000 FEET.

ONCE THAT STORM SYSTEM PASSES, SKIES WILL CLEAR DURING THE SECOND
HALF OF THE WEEKEND. OVERNIGHT TEMPERATURES WILL LIKELY DROP INTO
THE UPPER 20S TO MID 30S ACROSS MUCH OF THE REGION. THIS WILL
LIKELY RESULT IN WIDESPREAD FROST SATURDAY AND SUNDAY NIGHTS
ACROSS MUCH OF NORTHWEST OREGON AND SOUTHWEST WASHINGTON.

NOW IS A GOOD TIME TO PICK YOUR REMAINING VEGETABLES AND TO COVER
OTHER FROST SENSITIVE PLANTS. IT IS ALSO A GOOD TIME TO WINTERIZE
YOUR OUTDOOR PIPES AND HOSES FOR THE UPCOMING WINTER.
