DISCUSSION
EVENING UPDATE: IT'S A TALE OF TWO AIR MASSES ACROSS THE INLAND
NW THIS EVENING WITH DRIER AIR PUNCHING INTO CENTRAL WA WITH
DEWPOINTS IN MANY LOCATIONS IN THE 20S, AS PRECIPITABLE WATER
DECREASES TO 50-70% OF NORMAL. OVER THE ID PANHANDLE AND MID
LEVEL FRONTAL BOUNDARY LINGERS, WITH MUCH GREATER MOISTURE WITH
DEWPOINTS IN THE 40S AND PRECIPITABLE WATER 120-170% OF NORMAL.
MODELS SHOW LITTLE MOVEMENT WITH THE UPPER TROUGH TONIGHT, WHICH
IS EXPECTED TO ALLOW AREAS OF RAIN TO CONTINUE FROM THE CAMAS
PRAIRIE UP TOWARDS LOOKOUT PASS WITH A CHANCE OF LIGHT RAIN CLIPPING
THE PALOUSE, WHILE DRY CONDITIONS PERSIST ACROSS MOST OF CENTRAL
AND EASTERN WASHINGTON AND THE NORTH ID PANHANDLE. MADE A FEW EDITS
TO THE FORECAST TONIGHT, MAINLY TO ADJUST SKY COVER AROUND THE MOSES
LAKE AREA THIS EVENING TO SHOW MORE CLEARING, AND TO INCREASE WINDS
DOWN THE OKANOGON VALLEY THIS EVENING. A SHARP NORTH WIND SHIFT IN
OMAK OVER THE PAST HOUR DROPPED THE TEMPERATURE 10 DEGREES, WITH
NORTH WINDS GUSTING TO NEAR 40 MPH. OROVILLE IS ALSO BLOWING, WITH
GUSTS TO 44 MPH. AS THE COLD ADVECTION DECREASE LATER THIS EVENING, THE
GUSTS WILL GRADUALLY SUBSIDE BUT IT WILL STILL REMAIN BREEZY
OVERNIGHT INTO SUNDAY AS WINDS CHANNEL DOWN THE VALLEY WITH THE
NORTHERLY FLOW ON THE BACK SIDE OF THE UPPER TROUGH AS IT SLOWLY
MOVES EAST. JW
AVIATION
06Z TAFS: VFR CONDITIONS ARE FORECAST FOR ALL TAF SITES THROUGH
06Z MONDAY. A MID LEVEL FRONTAL BOUNDARY WILL CONTINUE TO
PRODUCE AREAS OF LIGHT RAIN, PRIMARILY EAST OF KLWS AND KCOE
THROUGH SUNDAY MORNING. AS DRIER AIR OVER CENTRAL WA CONTINUES
TO NOSE EAST, THIS SHOULD LIMIT THE POTENTIAL FOR FOG AND
STRATUS DEVELOPMENT OVERNIGHT ACROSS EASTERN WA/N IDAHO.
FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS:
ALTERNATE SCENARIO IS FOR THE MID LEVEL CLOUD DECK TO CLEAR MORE
THAN FORECAST OVER KLWS, WITH SHALLOW GROUND FOG DEVELOPING.
THIS CARRIES LOW CONFIDENCE AND NOT INCLUDED IN THE TAF'S.
-----------------------
CONFIDENCE DESCRIPTORS:
LOW - LESS THAN A 30 PERCENT CHANCE
MODERATE - 30 TO 70 PERCENT CHANCE
