OVERNIGHT LOWS WILL BE COLD WITH NEAR TO BELOW FREEZING

DRIER CONDITIONS RETURN FRIDAY THROUGH THE WEEKEND. NEXT ROUND

DISCUSSION
THURSDAY NIGHT THROUGH MONDAY: THURSDAY NIGHT WILL BE ANOTHER
CHILLY NIGHT WITH LIGHT WINDS AND MOSTLY CLEAR SKIES. BE
PREPARED TO PROTECT SENSITIVE PLANTS ONCE AGAIN WITH
TEMPERATURES FALLING BELOW FREEZING REGIONWIDE. DRY CONDITIONS
WILL CLOSE OUT THE WORK WEEK AND LAST THROUGH THE WEEKEND AS A
RIDGE OF HIGH PRESSURE BUILDS OVER THE REGION. IN ADDITION TO
DRY CONDITIONS, THE RIDGE WILL DELIVER LIGHT WINDS, WARMING
TEMPERATURES, AND CLEAR TO PARTLY CLOUDY SKIES.
AN AREA OF LOW PRESSURE ENTERS THE PICTURE BY LATE WEEKEND INTO
EARLY NEXT WEEK. THIS SYSTEM DROPS OUT OF THE GULF OF AK SUNDAY
INTO MONDAY AND FOLLOWS THE COASTLINE DOWN TO THE
OREGON/CALIFORNIA BORDER. MID TO HIGH LEVEL CLOUD COVER WILL
INCREASE, BUT MAINLY DRY CONDITIONS WILL CONTINUE FOR THE INLAND
NW THROUGH SUNDAY AND MONDAY WITH PERSISTENT EASTERLY WINDS.
TEMPERATURES WILL WARM BY 4 TO 8 DEGREES EACH DAY STARTING TODAY
(THURSDAY) THROUGH MONDAY. BY MONDAY AFTERNOON, HIGH
TEMPERATURES WILL RANGE FROM THE MID 70S TO THE LOW 80S, NEARLY
20 DEGREES ABOVE SEASONAL NORMS FOR MID TO LATE APRIL.
OVERNIGHT LOWS, HOWEVER, WILL STAY COOL IN THE MID 30S TO LOW
40S UNDER THE LIGHT WINDS AND CLEAR SKIES.
TUESDAY AND WEDNESDAY: TEMPERATURES WILL START TRENDING BACK
TOWARD SEASONAL NORMS BY MIDWEEK AS THE OFFSHORE LOW MOVES
INLAND AND WINDS SHIFT OUT OF THE SOUTHWEST. THERE IS STILL
SOME VARIATION WITHIN ENSEMBLES AS TO WHEN EXACTLY THE LOW WILL
MOVE ONSHORE AND WHAT TRACK IT WILL FOLLOW, BUT REGARDLESS,
PRECIPITATION AMOUNTS ARE LOOKING LIGHT AND SPOTTY, AS IS
TYPICAL WITH CONVECTIVE SPRING SHOWERS. /FEWKES
AVIATION
18Z TAFS: ASIDE FROM VERY LIGHT, SPOTTY SHOWERS TRACKING THROUGH
FAR NORTH ID, PRECIP HAS MOVED OUT OF THE AREA. THERE ARE
SEVERAL SITES (KGEG, KSFF, AND KPUW) WHERE FEW TO SCATTERED LOW
CLOUDS ARE LINGERING, BUT CONDITIONS ARE VFR AND ARE EXPECTED TO
STAY THAT WAY THROUGH THE PERIOD. WINDS WILL REMAIN BREEZY
THROUGH THE AFTERNOON WITH GUSTS AROUND 25KTS. THE SYSTEM WILL
BEGIN TO EXIT TONIGHT WITH CLEARING SKIES, DECREASING WINDS,
AND CHILLY TEMPERATURES.
FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS:
HIGH CONFIDENCE FOR VFR CONDITIONS THROUGH THE PERIOD, THOUGH
FOG IS POSSIBLE IN THE VALLEYS OF NE WA AND N ID TONIGHT.
