AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
223 PM PDT Mon Oct 4 2021

.SHORT TERM...SATELLITE IMAGERY SHOWS A COLD FRONT LOCATED WELL
OFF THE PACNW COAST. THIS COLD FRONT WILL APPROACH THE COAST
TONIGHT AND MOVE INTO THE COAST TOMORROW MORNING AND AFTERNOON.
THE FRONT IS FORECAST TO GRADUALLY MOVE INLAND ACROSS THE AREA
TUESDAY EVENING THROUGH WEDNESDAY EVENING. AHEAD OF THE FRONT,
MODELS CONTINUE TO INDICATE THAT GUSTY SOUTH TO SOUTHWEST WINDS
WILL OCCUR THIS AFTERNOON/EVENING AND AGAIN ON TUESDAY. WINDS WILL
BE STRONGEST ON TUESDAY. MODELS INDICATE A MID LEVEL JET WILL
MOVE ACROSS THE AREA WITH 700 MB WINDS OF 40 TO 45 KT OVER NORTH-
CENTRAL AND NORTHEAST PORTIONS OF THE CWA LATE TONIGHT INTO
TUESDAY. THIS JET ALONG WITH AN INCREASING SURFACE PRESSURE
GRADIENT WILL ALLOW FOR SOME LOCALLY STRONG, GUSTY WINDS,
ESPECIALLY OVER HIGHER TERRAIN EAST OF THE CASCADES. GUSTS OF 40
TO 45 MPH ARE EXPECTED ON TUESDAY OVER EASTERN RIDGES, MAINLY IN
THE WINTER RIM AND SUMMER LAKE AREA AS WELL AS ACROSS EASTERN
PORTIONS OF THE BOOTLEG BURN SCAR. STRONG, GUSTY WINDS MAY CAUSE
TREE LIMBS TO BE BLOWN DOWN AND A FEW POWER OUTAGES. DAMAGED
TREES MAY ALSO BE BLOWN DOWN IN STRONG WINDS.

PRECIPITATION WITH THIS FRONT WILL BE MAINLY LIGHT WITH SOME
MODERATE AMOUNTS WEST OF THE CASCADES. MODERATE PRECIPITATION
WITH RAINFALL AMOUNTS OF 0.25 INCHES OR HIGHER ARE LIKELY ALONG
THE COAST AND OVER THE COASTAL MOUNTAINS. IN THE UMPQUA BASIN, EXPECT
AROUND A 50 PERCENT CHANCE FOR RAINFALL AMOUNTS OF 0.25 INCHES OR
HIGHER. MOST OTHER AREAS WEST OF THE CASCADES, HAVE LOWER CHANCES
FOR MODERATE RAIN, WITH MAINLY LIGHT RAINFALL EXPECTED. LIGHT
RAIN WILL SPREAD INTO AREAS EAST OF THE CASCADES TUESDAY NIGHT AND
WEDNESDAY MORNING WITH AMOUNTS GENERALLY LESS THAN 0.10 INCHES.
SOME AREAS EAST OF THE CASCADES, ESPECIALLY ACROSS SOUTHEAST LAKE
AND MODOC COUNTIES, MAY SEE LITTLE OR NO PRECIPITATION.

BEHIND THIS FRONT, EXPECT A CHANGE TO MUCH COOLER WEATHER ON
WEDNESDAY WITH HIGHS IN THE 50S AND 60S ACROSS INLAND VALLEYS AND
SOME LINGERING LIGHT ISOLATED TO SCATTERED SHOWERS. LOW
TEMPERATURES WEDNESDAY NIGHT INTO THURSDAY MORNING ARE EXPECTED TO
DROP INTO THE 30S FOR VALLEYS EAST OF THE CASCADES AND INTO THE
MID 30S TO LOWER 40S FOR VALLEYS WEST OF THE CASCADES. THERE IS A
POTENTIAL FOR CLOUDS TO PARTIALLY CLEAR THURSDAY MORNING WEST OF
THE CASCADES. IF THIS OCCURS, WE MAY SEE PATCHY FROST DEVELOP IN
WESTERN VALLEYS.

.LONG TERM...THURSDAY THROUGH MONDAY...AN UPPER LEVEL TROUGH WILL
REMAIN OVER THE AREA ON THURSDAY WITH SOME SCATTERED SHOWERS EAST
OF THE CASCADES AND COOL TEMPERATURES ACROSS THE AREA. THE UPPER
TROUGH WILL DEEPEN FRIDAY AND ANOTHER COLD FRONT WILL MOVE INLAND.
THIS FRONT WILL WEAKEN AS IT MOVES INTO THE COAST AND COASTAL
MOUNTAINS THOUGH, SO EXPECT ONLY LIGHT PRECIPITATION TO SPREAD
INTO WESTERN PORTIONS OF THE AREA AND INTO THE CASCADES. SHOWERS
WILL DIMINISH FRIDAY NIGHT INTO EARLY SATURDAY AND A WEAK HIGH
PRESSURE RIDGE BUILDS IN ON SATURDAY. HOWEVER, ANY BREAK IN THE
ACTIVE PATTERN WILL LIKELY BE BRIEF AS MODELS AND ENSEMBLES SHOW
ANOTHER FRONT AND UPPER TROUGH GRADUALLY MOVING INTO THE REGION
SUNDAY INTO MONDAY.

&&

.AVIATION...04/18Z TAFS...VFR CONDITIONS ARE EXPECTED THROUGH THIS
EVENING, WITH THE EXCEPTION OF LOCAL IFR IN FOG AND LOW STRATUS IN
THE UMPQUA BASIN THAT SHOULD LIFT SOON. GUSTY SOUTHWEST WINDS WILL
DEVELOP THIS AFTERNOON ALONG AND EAST OF THE CASCADES, AS WELL AS IN
THE SHASTA VALLEY. IFR STRATUS AND AREAS OF RAIN ARE LIKELY TO
DEVELOP ALONG THE COAST AND INTO THE COQUILLE VALLEY TOMORROW
MORNING, WITH RAIN MOVING INLAND DURING THE DAY. -SVEN

&&

.MARINE...UPDATED 200 PM PDT MONDAY 4 OCTOBER 2021...A FRONT WILL
MOVE ACROSS THE WATERS LATE TONIGHT INTO TUESDAY, PRODUCING RAIN AND
GUSTY SOUTH WINDS. THIS WILL BE FOLLOWED BY NORTHWEST WINDS AFTER
THE FRONT PASSES LATE TUESDAY MORNING. ANOTHER FRONT WILL MOVE
ONSHORE WEDNESDAY, BRINGING A BRIEF PERIOD OF SOUTH WINDS TO THE
AREA. GUSTY NORTH WINDS AND STEEP WIND-DRIVEN SEAS WILL RETURN WITH
THE THERMAL TROUGH WEDNESDAY NIGHT, WEAKENING THURSDAY NIGHT.
ANOTHER FRONT WILL APPROACH THE WATERS FRIDAY.

LONGER PERIOD SWELL HEIGHTS (THOSE AT ROUGHLY 12 SECONDS OR GREATER)
HAVE BEEN REGULARLY UNDER-PREDICTED BY WAVE GUIDANCE OVER THE PAST
SEVERAL WEEKS. WHILE WE ARE TRYING TO CORRECT FOR THIS IN THE
FORECAST, IT IS POSSIBLE THAT SWELLS COULD ARRIVE ONE TO TWO FEET
HIGHER THAN PREDICTED. BE SURE TO CHECK THE MOST RECENT BUOY
OBSERVATIONS BEFORE HEADING OUT INTO THE COASTAL WATERS.

&&

.FIRE WEATHER...UPDATED 200 PM PDT MONDAY 4 OCTOBER 2021...WINDS
OVER THE RIDGES COMBINED WITH POOR TO MODERATE HUMIDITY RECOVERIES
WILL CREATE NEAR CRITICAL FIRE WEATHER CONDITIONS OVER WESTERN AND
SOUTH CENTRAL SISKIYOU COUNTY TONIGHT. AT THIS TIME, IT DOES NOT
LOOK LIKE RED FLAG WARNING CONDITIONS WILL DEVELOP.

A FRONT WILL MOVE ONSHORE TUESDAY, BRINGING WETTING RAINS TO THE
COAST AND COAST RANGE TUESDAY AND A CHANCE OF WETTING RAINS FROM THE
CASCADES WEST TUESDAY INTO TUESDAY NIGHT. IT WILL BE VERY WINDY EAST
OF THE CASCADES TUESDAY, BUT HUMIDITIES WILL BE HIGHER, SO CRITICAL
FIRE WEATHER CONDITIONS ARE NOT EXPECTED. COOL AND UNSETTLED WEATHER
WILL PERSIST INTO THE WEEKEND, BUT PRECIPITATION WILL BE SPOTTY AND
LIGHT.

&&

.MFR WATCHES/WARNINGS/ADVISORIES...
OR...WIND ADVISORY FROM 5 AM TO 7 PM PDT TUESDAY FOR ORZ030-031.

CA...NONE.

PACIFIC COASTAL WATERS...
     SMALL CRAFT ADVISORY UNTIL 5 PM PDT THIS AFTERNOON FOR
