KEY MESSAGES
- WEATHER CHANGES ARRIVE FRIDAY INTO THE WEEKEND WITH MUCH
COOLER TEMPERATURES, GUSTY WINDS, AND RAIN SHOWERS.
SYNOPSIS
A PATTERN CHANGE ARRIVES ON FRIDAY AS A WEATHER SYSTEM DELIVERS
MUCH COOLER TEMPERATURES, GUSTY WINDS, AND RAIN SHOWERS FOR
MUCH OF THE REGION. COOL AND SHOWERY CONDITIONS PERSIST THROUGH
THE WEEKEND AND INTO EARLY NEXT WEEK.
DISCUSSION
TODAY AND TONIGHT: THE PERIOD OF THE HOT, DRY CONDITIONS IS
EXPECTED TO COME TO AN END TODAY. A LOW WILL MOVE SOUTH ALONG
THE WASHINGTON COAST LINE. AS THE DAY PROGRESSES, IT WILL DRAW
INCREASE MOISTURE INTO THE INLAND NORTHWEST BRINGING INCREASED
CLOUDS AND SHOWER CHANCES. THE CLOUDS WILL KEEP THE ENVIRONMENT
COOLER FROM PREVIOUS DAYS. HIGHS FOR TODAY ARE EXPECTED TO PEAK
IN THE UPPER 60S AND 70S. THE CASCADE RAIN SHADOW EFFECT WILL
CONTINUE TO IMPACT PRECIP CHANCES FOR THE LEE OF THE CASCADES
WITH LITTLE TO NO ACCUMULATION EXPECTED FROM ELLENSBURG TO OMAK.
THE REST OF THE REGION WILL LIKELY GET A WETTING RAIN(0.10 INCH)
WITH A 40% OR MORE PROBABILITY THROUGH TONIGHT. THE BEST CHANCES
ARE OVER NORTHEAST WA AND NORTH(50% OR GREATER PROBABILITY OF
0.3 INCH). SPOKANE HAS 15% PROBABILITY OF 0.3 INCH. ENSEMBLES
SHOW INSTABILITY ALONG WITH THE MOISTURE STARTING LATE MORNING
AND LASTING INTO THE EARLY HOURS. CAPE IS 300-700 J/KG. INDICES
SUPPORT WEAK THUNDERSTORM DEVELOPMENT. BEST CHANCES FOR
THUNDERSTORMS WILL BE NORTHEAST WA AND NORTH ID. IMPACTS
EXPECTED TO BE GUSTY WINDS NEAR 40 MPH, LIGHTNING, SMALL HAIL,
AND BRIEF HEAVY RAIN. WINDS OUTSIDE OF THUNDERSTORMS WILL BE
SOUTHERLY IN THE TEENS WITH GUSTS INTO THE LOW 20 MPH RANGE.
CONDITIONS WILL CALM OVERNIGHT WITH RAIN CHANCES CONTINUING.
OVERNIGHT LOWS WILL BE IN THE 40S TO LOW 50S.
SATURDAY AND SUNDAY: THE LOW WILL TRACK THROUGH OREGON OVER THE
WEEKEND. PRECIP CHANCES WILL DECREASE FOR MOST OF THE WESTERN
BASIN. MOISTURE WRAPPING AROUND THE LOW WILL KEEP CHANCES HIGH
FOR THE IDAHO PANHANDLE AND DECREASE AS IT MOVES WEST,
ESPECIALLY ON SUNDAY. FOR THE WEEKEND, THE IDAHO PANHANDLE HAS A
25-75% PROBABILITY OF 0.3-1 INCH. EASTERN WASHINGTON HAS
0.1-0.5 INCH. INSTABILITY IS NOT AS STRONG LEADING TO LOWER
THUNDER THREAT. WINDS WILL CONTINUE TO BE SUSTAINED IN THE TEENS
WITH GUSTS INTO THE 20S. HIGHS WILL BE IN THE 60S AND 70S.
MONDAY THROUGH THURSDAY: THE TROUGH PATTERN IS EXPECTED TO
REMAIN IN PLACE THROUGH THE NEXT WEEK. ENSEMBLES ARE IN GOOD
AGREEMENT. A DRIER PATTERN WILL BRING A GRADUAL WARMING TREND TO
THE REGION. PRECIP CHANCES WILL BE OCCASIONALLY OVER THE HIGHER
TERRAIN. HIGHS WILL CLIMB BACK INTO THE 70S AND LOW 80S. A FAR
LOOK INTO THE JULY 4TH WEEKEND, SHOWS NEAR NORMAL TEMPS AND
ABOVE NORMAL PRECIP. /JDC
AVIATION
12Z TAFS: THERE IS A 60-90% CHANCE OF MVFR CEILINGS FOR KGEG-
KSFF-KCOE-KPUW FROM 15Z-21Z AS BANDS OF SHOWERS MOVE THROUGH THE
REGION. BEHIND THIS BAND OF SHOWERS, SCATTERED SHOWERS WILL
DEVELOP ACROSS THE REGION AS WEAK CONVECTIVE INSTABILITY BUILDS.
THERE MAY BE EMBEDDED THUNDER WITHIN ANY CELL THAT DEVELOPS.
THE BEST CHANCES FOR IMPACTS FROM THESE SHOWERS AND POTENTIAL
THUNDERSTORMS ARE AROUND KMWH-KGEG-KSFF-KCOE-KPUW. THESE SHOWERS
MAY BRING BRIEF VISIBILITY RESTRICTIONS AND GUSTY OUTFLOW WINDS
UP TO 20 KT, BUT CONFIDENCE IS TOO LOW TO INCLUDE IN ANY TAF
SITES. OTHERWISE, EXPECT VFR CONDITIONS WITH BREEZY WEST WINDS
DEVELOPING IN THE AFTERNOON IN THE CASCADE GAPS.
FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS:
CONFIDENCE IS MODERATE FOR MVFR CEILINGS AT KGEG-KSFF-KCOE-
KPUW. IF SHOWER COVERAGE IS LOWER THAN WHAT THE HIGH-RES MODELS
INDICTATE, THESE SITES MAY STAY ABOVE MVFR CIGS (10-40% CHANCE).
-----------------------
CONFIDENCE DESCRIPTORS:
LOW - LESS THAN A 30 PERCENT CHANCE
MODERATE - 30 TO 70 PERCENT CHANCE
HIGH - GREATER THAN A 70 PERCENT CHANCE
