KEY MESSAGES
- LIGHT PRECIPITATION CONTINUES FOR PARTS OF THE BLUES AND
CASCADES THROUGH TONIGHT. WINDS REMAIN MOSTLY LIGHT WITH THE
POSSIBLE EXCEPTION OF THE LA GRANDE AREA ON TUESDAY.
- DRY CONDITIONS WILL RESUME TOMORROW WITH A MORE SUBSTANCE
PATTERN DUE TO AN AMPLIFYING RIDGE THROUGH THE WEEK.
- UNCERTAINTY INCREASES HEADING TOWARDS THE WEEKEND, WITH NO
CLEAR CONSENSUS ON A SYNOPTIC SOLUTION.
DISCUSSION
DENSE FOG FROM EARLIER THIS MORNING HAS SINCE
MOSTLY DISSIPATED, WITH LINGERING SHOWERS IN THE FOOTHILLS AND
CASCADES. PRECIPITATION WILL CONTINUE THROUGH THE NIGHT AS A
SHORTWAVE CONTINUES MAKING ITS WAY THROUGH THE REGION. EXPECTING
CONDITIONS TO CONTINUE TO DRY AS WE GO THROUGH THE NIGHT
TONIGHT AS A RIDGE BEGINS TO AMPLIFY OVER THE PACNW OVER THE
NEXT SEVERAL DAYS. RIDGING WILL BRING US MORE BENIGN WEATHER
AFTER A SHORT BREAK BURST OF MOISTURE TODAY. THIS WILL RESULT IN
HIGH PRESSURE TO SETTLE INTO THE AREA ALLOWING FOR THE STRATUS
DECK AND FOG TO RE-DEVELOP OVER THE NEXT COUPLE OF DAYS. MORE
THAN LIKELY WE WILL HAVE THE SAME AREAS OF CONCERN AS BEFORE FOR
DENSE FOG IN PARTS OF THE BASIN, FOOTHILLS, AND KITTITAS
VALLEY. DESPITE UNDER THE INFLUENCE OF A RIDGE AND HIGH
PRESSURE, THERE IS SMALL POTENTIAL FOR SOME BREEZY WINDS IN THE
LA GRANDE AREA TUESDAY MORNING THRU WEDNESDAY AFTERNOON.
PRESSURE GRADIENT DIFFERENCES BETWEEN BKE AND MEH ARE IN THE 6-8
MB RANGE, ALTHOUGH NBM IS NOT PICKING UP ANY POTENTIAL FOR WIND
ADVISORY CRITERIA TO TAKE PLACE. AN EDIT TO LA GRANDE'S WINDS
LATER ON IF CONFIDENCE INCREASES FOR BREEZIER CONDITIONS.
THE FORECAST BECOMES A BIT QUESTIONABLE GOING INTO FRIDAY
ONWARDS, AS THE RIDGE BEGINS TO WEAKENS AND HEADS EAST. CLUSTERS
ON THIS MATTER TEND TO WANT TO LEAN ON A WETTER SOLUTION, AS 68%
OF MEMBERS WANT TO LEAN ON A STRONGER ONCOMING SHORTWAVE WITH
LIGHT PRECIPITATION BY SATURDAY MORNING, WHILE THAT INCREASES TO
74% BY SUNDAY MORNING. ALTHOUGH, MOST OF THE MEMBERS WANT TO
BRING LIGHT PRECIPITATION INTO THE AREA BY THE WEEKEND, IT'S
STILL A BIT UNCERTAIN HOW THE SYNOPTIC PLAYS OUT GOING INTO THE
WEEKEND. ALTHOUGH IT IS WORTH NOTING THAT ANY WET SOLUTION DOES
NOT DEPICT SIGNIFICANT PRECIPITATION AMOUNTS, SANS THE 22% OF
MEMBERS THAT BRING MODERATE TO HEAVY PRECIP INTO THE CASCADES
OVER THE WEEKEND. ALL IN ALL IT'S A SYSTEM WITH PLENTY OF TIME
FOR MONITORING FOR NOW.
AVIATION /00Z TAFS THROUGH 00Z TUESDAY/
THE FOG HAS FINALLY
LIFTED SINCE THIS MORNING WITH THE HELP FROM THIS FRONTAL
SYSTEM. ALL SITES WILL BE VFR THROUGH THE PERIOD. HOWEVER, KYKM
MAY BECOME MVFR DURING OVERNIGHT HOURS AND LATE MONDAY MORNING
DUE TO LINGERING LOW CIGS (BKN AT 025) FROM THIS SYSTEM. LIGHT
RAIN IS EXPECTED TO LINGER FOR KDLS/KYKM THROUGH THIS EVENING AS
WELL, WHICH SOME PROB30 GROUPS WERE MENTIONED FOR -RA AT THOSE
AIRPORTS. PERIODIC GUSTS UP TO 20KTS MIGHT CONTINUE OVER
KRDM/KBDN THIS EARLY EVENING, ADDED TEMPO GROUPS FOR THEM SINCE
CONFIDENCE WAS MODERATE (>50%) ON THE BRIEF EXTENT. OTHERWISE,
WINDS WILL BE LESS THAN 12KTS FOR THE REMAINING SITES.
