SOUTHWEST OREGON/NORTHERN CALIFORNIA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
230 PM PDT FRI JUL 13 2001

THE UPPER LEVEL TROUGH WHICH HAD BEEN OFFSHORE ALL WEEK WILL MOVE
ACROSS NORTHERN CALIFORNIA ON SATURDAY. THE MOIST AND UNSTABLE AIR
MASS IS MOVING EAST AHEAD OF THE TROUGH. CUMULUS DEVELOPMENT SO FAR
TODAY IS NOT THAT IMPRESSIVE. BUT SHOULD STILL SEE SOME BUILDUPS WITH
A SLIGHT CHANCE OF THUNDERSTORMS LATER THIS AFTERNOON INTO THE
EVENING...MAINLY ALONG THE CASCADES AND LAKE/MODOC COUNTIES. AS
THE UPPER TROUGH MOVES INLAND TOMORROW THERE WILL BE A SURGE OF
MARINE AIR WITH LOW CLOUDS INTO THE UMPQUA BASIN. DURING THE
AFTERNOON THEY SHOULD JOIN THE REST OF OUR INLAND AREA WITH MOSTLY
SUNNY SKIES AND SLIGHTLY COOLER TEMPERATURES. WILL MAINTAIN A SLIGHT
CHANCE OF AFTERNOON/EVENING THUNDERSTORMS FROM THE CASCADES EASTWARD.
FURTHER SLIGHT COOLING ON SUNDAY WITH THE FLOW ALOFT BECOMING WEST AS
A STRONGER UPPER LOW DROPS SOUTHEAST ACROSS BRITISH COLUMBIA. 12Z AVN
FINALLY LOOKS MORE REALISTIC FOR SUNDAY WITH WEAK INSTABILITY ONLY
OVER LAKE AND MODOC COUNTIES FOR CONTINUED POSSIBILITY OF
THUNDERSTORMS. ON MONDAY THE UPPER LOW WILL BE CENTERED NEAR THE
CANADIAN BORDER WITH THE TROUGH AXIS ALONG THE PACIFIC COAST. A
COUPLE OF SHORTWAVES ARE EXPECTED TO MOVE EAST ACROSS OREGON SO WILL
EXTEND SLIGHT CHANCE OF SHOWERS EAST FROM COOS COUNTY INTO THE UMPQUA
AND CASCADES FOR MONDAY AND TUESDAY. TUESDAY LOOKS TO BE THE COOLEST
DAY WITH HIGH TEMPS AROUND 10 DEGREES BELOW NORMAL. A GRADUAL WARM UP
FOR THE LATTER PART OF THE WEEK AS THE UPPER LOW REMAINS OVER THE
PACIFIC NORTHWEST AND WEAKENS. WEYGAND

.MFR...SMALL CRAFT ADVISORY FROM FLORENCE OR TO PT ST GEORGE CA.
