AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
912 AM PST TUE MAR 2 2010
.DISCUSSION...FRONTAL BOUNDARY PUSHING INLAND THIS MORNING WITH
THE BACK EDGE OF CLOUD COVER TO JUST NEAR THE COAST. UPDATED
GRIDS THIS MORNING TO ACCOUNT FOR LOWER POPS AND LESS CLOUD COVER
WEST SIDE THIS AFTERNOON/EVENING AS THERE WILL LIKELY BE A BREAK
BETWEEN THIS SYSTEM AND THE UPPER LOW THAT WILL BE HEADED TOWARD
THE AREA LATER TONIGHT INTO WEDNESDAY MORNING. REST OF THE GOING
FORECAST LOOKS GOOD AT THIS POINT...SO WILL LEAVE UNCHANGED. WILL
BE TAKING A HARD LOOK AT SYSTEM COMING IN TONIGHT TO SEE IF
ANYTHING NEEDS TO BE UPDATED AS FAR AS SNOW LEVELS...AND/OR TIMING.
BUT IT DOES LOOK LIKE THERE WILL BE A 4 TO 6 HOUR PERIOD OF
STEADY/HEAVY PRECIPITATION IN PORTIONS OF SISKIYOU
COUNTY LATE TONIGHT INTO THURSDAY MORNING...PARTICULARLY NEAR THE
MOUNT SHASTA AREA WITH SNOW LEVELS LOWERING TO NEAR 3000 FEET.
&&
.AVIATION...MVFR CIGS WITH LOCAL MOUNTAIN OBSCURATIONS IN AREAS OF
RAIN WEST SIDE LATE THIS MORNING LIFTING TO VFR ON THE BACK SIDE
OF THE FRONT THIS AFTERNOON. THERE CAN STILL BE LOCAL IFR
CONDITIONS RIGHT ALONG THE COAST NEAR KBOK FOR THE NEXT FEW HOURS.
VFR CIGS EAST SIDE LATE THIS MORNING LOWERING TO MVFR THIS
AFTERNOON IN AREAS OF RAIN.
&&
.PREV DISCUSSION... /ISSUED 314 AM PST TUE MAR 2 2010/
DISCUSSION...CURRENT SATELLITE IMAGE SHOWS THE BACK EDGE OF THE
COLD FRONT REACHING THE OREGON COAST. AHEAD OF THE FRONT... MOST OF
PRECIPITATION IS CONFINED TO NORTHWEST CALIFORNIA AND SOUTHWEST
OREGON. THE FRONT WILL SLOWLY WORK ITS WAY INLAND THIS MORNING
AND AFTERNOON WITH MOST OF THE PRECIPITATION CENTERED IN THE MOUNT
SHASTA AREA. ELSEWHERE SHOWERS WILL BE ON THE DECREASE WITH MOST
CENTERED ALONG THE CASCADES AND HIGHER TERRAIN EAST OF THE
CASCADES. SNOW LEVELS START OUT AROUND 4500 FEET THIS
MORNING...THEN RISING TO 5000 IN THE AFTERNOON...BUT THEY WILL
REMAIN AROUND 4500 FEET AROUND MOUNT SHASTA.
MODELS SHOW A COLD UPPER LOW WITH 500 MB TEMPS BETWEEN -30 AND
-33 C MOVING INTO NORTHWEST CALIFORNIA EARLY WEDNESDAY MORNING.
THE BULK OF THE PRECIPITATION WITH THIS LOW WILL ONCE AGAIN BE
CENTERED IN NORTHERN CALIFORNIA AND EXTREME SOUTHWEST OREGON. SNOW
LEVELS TONIGHT LOWER TO AROUND 3000 FEET. THIS ALONG WITH
INCREASING PRECIPITATION COULD LEAD TO ACCUMULATING SNOW IN
SISKIYOU COUNTY. THE MODELS SUGGEST QPF WILL DECREASE IN THE
AFTERNOON...BUT FIND THIS SUSPECT FOR THE FOLLOWING REASON. THE
UPPER LOW MOVES INTO NORTHERN CALIFORNIA WEDNESDAY AFTERNOON WHICH
WILL COME AT A TIME OF MAX SURFACE HEATING. THEREFORE WE CAN
EXPECT SHOWERS TO ACTUALLY INCREASE IN COVERAGE AND INTENSITY.
THE UPPER LOW MOVES INTO WESTERN NEVADA WEDNESDAY NIGHT AND THIS
ALONG WITH DECREASING DAYTIME HEATING WILL RESULT IN SHOWERS RAPIDLY
DECREASING AFTER DARK WEST OF THE CASCADES. BOTH THE GFS AND ECMWF
SUGGEST WRAPAROUND MOISTURE WILL MOVE INTO EASTERN OREGON WITH AN
UPSLOPE COMPONENT. THEREFORE WE'LL KEEP POPS HIGHER ALONG AND EAST
OF THE CASCADES AND KEEP THEM BELOW SLIGHT CHANGES WEST OF THE
CASCADES.
SHORTWAVE RIDGING MOVES INTO THE AREA THURSDAY NIGHT...THEN ANOTHER
UPPER LOW MOVES INTO NORTHERN CALIFORNIA FRIDAY. THE ECMWF TRACKS
THE LOW FARTHER WEST AND SOUTH WHICH OF CORRECT WILL LEAD TO DRY
CONDITIONS. THE GFS HAS THE LOW TRACKING FARTHER NORTH AND EAST
WHICH WILL BRING PRECIPITATION TO THE SAME AREA AS ARE EXPECTED
TODAY.
AVIATION...CIGS AND VIS LOWER IN SHOWERS EARLY THIS MORNING. CIGS
HAVE LOWERED TO IFR ALONG THE SOUTH COAST AND IT'S EXPECTED TO LOWER
ALONG THE NORTH COAST BY MID MORNING. CIGS SHOULD INCREASE THIS
AFTERNOON IN THE WAKE OF THE FRONT WITH VFR AND LOCAL MVFR
CONDITIONS EXPECTED. VFR CONDITIONS CONTINUE INLAND INTO EARLY THIS
MORNING...THEN CIGS LOWER CLOSE TO MVFR AFTER 18Z IN SHOWERS. VIS
SHOULD REMAIN AROUND 6 MILES AROUND THE KMFR AND KLMT
TERMINALS...BUT MTNS WILL OCCASIONALLY BE OBSCURED IN LOWER CIGS AND
SHOWERS.
