AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
450 PM PDT TUE JUL 21 2015
UPDATED AVIATION SECTION
.SHORT TERM...AS ADVERTISED...THUNDERSTORMS ARE FIRING UP IN
SISKIYOU AND MODOC COUNTIES THIS AFTERNOON. STORMS WILL CONTINUE
THROUGH THE EVENING AND MAY LINGER WELL AFTER SUNSET AS THEY GET
TRIGGERED BY A SHORTWAVE APPROACHING THE COAST. THE TROF ASSOCIATED
WITH THIS SHORTWAVE WILL CONTINUE TO ALSO APPROACH THE COAST
OVERNIGHT.
INSTABILITY TOMORROW LOOKS TO BE IN THE SAME GENERAL AREA AS
TODAY. THE DIFFERENCE IS IN THE AMOUNT OF MOISTURE AVAILABLE TO
FEED STORMS. DRIER AIR WILL MOVE INTO SISKIYOU AND WESTERN MODOC
COUNTY TOMORROW AFTERNOON SO ANY STORMS THAT DEVELOP WILL BE FEWER
AND SMALLER. HOWEVER...EASTERN MODOC COUNTY COULD STILL SEE MORE
AND BIGGER STORMS. IT JUST DEPENDS ON HOW QUICKLY THE TROF AND
DRIER AIR SWEEPS EASTWARD.
.LONG TERM...COOLER AND MORE STABLE AIR UNDER A WESTERLY FLOW
TAKES OVER ON THURSDAY AND CONTINUES THROUGH EARLY NEXT WEEK.
ANOTHER WEAK TROF MOVES THROUGH THE PACIFIC NORTHWEST ON SUNDAY.
THIS WILL KEEP TEMPERATURES SLIGHTLY BELOW NORMAL. WESTERLY WINDS
COULD BE BREEZY AT TIMES ESPECIALLY ON EXPOSED MOUNTAIN RIDGES.
&&
.AVIATION...FOR THE 22/00Z TAF CYCLE...THUNDERSTORMS ARE CURRENTLY
ONGOING ACROSS PORTIONS OF NORTHERN CALIFORNIA AND EAST OF THE
CASCADES AND WILL CONTINUE UNTIL SHORTLY AFTER SUNSET. THESE STORMS
WILL PRODUCE FREQUENT LIGHTNING, HEAVY RAIN, AND SMALL HAIL.
OTHERWISE, THE MAIN CONCERN WILL BE GUSTY WINDS ACROSS THE ENTIRE
FORECAST AREA. THE WINDS ARE EXPECTED TO DIMINISH THIS EVENING
BEFORE RETURNING TOMORROW AFTERNOON. SKIES WILL REMAIN VFR EXCEPT
FOR THE UMPQUA BASIN WHICH COULD SEE BRIEF PERIODS OF MVFR
SKIES...AND THE COAST WHICH WILL BECOME IFR THIS EVENING BEFORE
SCATTERING BACK OUT TOMORROW MORNING. -SCHAAF
&&
.MARINE...UPDATED 300 PM PDT, TUESDAY, 21 JULY 2015... NORTH WINDS
WILL PEAK THIS EVENING AS HIGH PRESSURE BUILDS INTO THE PACIFIC
NORTHWEST AND LOW PRESSURE NUDGES NORTHWARD ALONG THE COAST IN
NORTHERN CALIFORNIA. A HAZARDOUS SEAS AND GALE WARNING HAVE BEEN
ISSUED FOR THE INCREASE IN WINDS AND SEAS WEST OF PISTOL RIVER SOUTH
THROUGH PORT SAINT GEORGE. WINDS WILL WEAKEN OVERNIGHT BUT REMAIN IN
ADVISORY LEVELS THROUGH WEDNESDAY NIGHT. THE HIGH PRESSURE IS THEN
FORECAST TO SHIFT INLAND ON THURSDAY CAUSING THE NORTH WINDS TO
WEAKEN. SHORT PERIOD SEAS AND WINDS ARE EXPECTED TO FALL TO BELOW
ADVISORY THRESHOLDS ON WEDNESDAY EVENING WHERE THEY SHOULD REMAIN
THROUGH THE WEEKEND. -SCHAAF
&&
.FIRE WEATHER...UPDATED 130 PM PDT, TUESDAY 21 JULY 2015...
THE GFS, NAM, RAP, AND HRRR MODELS ARE IN EXCELLENT AGREEMENT
REGARDING THE EXTENT OF INSTABILITY AND THE LOCATION OF
THUNDERSTORMS THROUGH TONIGHT. THE RED FLAG WARNING REMAINS IN
EFFECT THROUGH THIS EVENING FOR EASTERN SISKIYOU COUNTY, EXTREME
SOUTHEAST KLAMATH COUNTY, SOUTHERN LAKE COUNTY, AND MODOC COUNTY. A
FEW THUNDERSTORMS HAVE ALREADY DEVELOPED IN THAT AREA WITH COVERAGE
EXPECTED TO EXPAND TO SCATTERED AS THERE IS A SHORTWAVE ALONG THE
NORTHERN CALIFORNIA COAST NEAR CAPE MENDOCINO AND ANOTHER ALONG THE
CALIFORNIA/NEVADA BORDER THAT WILL MOVE NORTH TO NORTHEAST. A BIT
BEYOND THE RED FLAG WARNED AREA, ISOLATED THUNDERSTORMS ARE EXPECTED
FARTHER WEST AND NORTH TO SOUTHWEST SISKIYOU COUNTY, THE NORTHERN
CALIFORNIA CASCADES TO THE KLAMATH BASIN AND MUCH OF THE REMAINDER
OF LAKE COUNTY. THE CELLS WILL PRODUCE MODERATE TO HEAVY RAIN BUT
WILL BE FASTER MOVING THAN USUAL AT 15 TO 20 KT, WHICH WILL INCREASE
THE RISK OF LIGHTNING PRODUCING FIRE STARTS. AFTER THIS EVENING INTO
WEDNESDAY MORNING, ACTIVITY IS EXPECTED TO DIMINISH BUT NOT
ALTOGETHER END AS A SHORTWAVE LINGERS OVER THE EAST SIDE AND THE
LARGER SCALE UPPER TROUGH WORKS ITS WAY INTO THE PACIFIC NORTHWEST.
WITH LITTLE CHANGE NECESSARY IN THE FIRST PERIOD OF THE FORECAST,
THE QUESTION OF THE DAY WAS THE EXPECTED COVERAGE OF THUNDERSTORMS
ON WEDNESDAY AFTERNOON. THE UPPER TROUGH WILL KICK THE REGION OF
DEEPER MOISTURE EAST TO THE EASTERN EDGE OF OUR AREA...INCLUDING THE
WARNER MOUNTAINS...AND EXTENDING TO THE EAST OUT OF OUR AREA. BUT,
THE GFS INDICATES SURFACE BASED CAPE VALUES OF 250 TO 750 J/KG IN
NORTHERN CALIFORNIA AND SOUTHERN LAKE COUNTY ON WEDNESDAY COMPARED
TO VALUES OF 750 TO 1500 J/KG TODAY. THUS, WILL HOLD EXPECTED
COVERAGE OF THUNDERSTORMS TO ISOLATED WITH A FOCUS FOR THE HIGHEST
PROBABILITY IN SOUTHEAST LAKE COUNTY. THE ARRIVAL OF THE TROUGH WILL
ALSO PRODUCE SLIGHTLY STRONGER THAN NORMAL AFTERNOON AND EVENING
WESTERLY WINDS.
THE UPPER TROUGH WILL CONTINUE TO TRACK EAST ON THURSDAY WITH A
WARM, STABLE AIR MASS ARRIVING. NEAR NORMAL TEMPERATURES AND BREEZY
WESTERLY AFTERNOON WINDS ARE EXPECTED AT THE END OF WEEK INTO
EARLY NEXT WEEK. /DW
