AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
110 PM PDT MON AUG 7 2006
.DISCUSSION...UPPER LEVEL LOW CENTERED OVER NORTHWEST CALIFORNIA AND
SLOWLY LIFTING NORTHEAST. MAJORITY OF THE CONVECTION AND INSTABILITY
IS OVER THE NORTHWEST SECTOR OF THE LOW IN THE AREA OF THE UPPER
LEVEL DIFLUENCE. THUNDERSTORMS HAVE REACHED THE COASTAL WATERS SO
THE EVENING UPDATE OF THE MARINE FORECAST NOW HAS THUNDERSTORMS.
GREATEST SHEAR ASSOCIATED WITH THE LOW RUNS THROUGH CENTRAL OREGON
SO THE LARGEST THUNDERSTORMS FOR THE REST OF THE EVENING SHOULD BE
IN DESCHUTES COUNTY AND NORTHWARD. SOME WEAK INSTABILITY REMAINS
OVER NORTHEAST CALIFORNIA AND SOUTH CENTRAL OREGON FOR SMALL
ISOLATED STORMS.
&&
.PREVIOUS DISCUSSION...THE CUTOFF LOW IS NOW NORTH OF THE BAY AREA
AND MOVING NORTH. THE ASSOCIATED DEFORMATION ZONE IS OVER OREGON
WITH A BAROCLINIC LEAF EXTENDING FROM NORTHERN CALIFORNIA INTO
SOUTHERN OREGON. THUNDERSTORMS ARE NOW IN PROGRESS OVER SISKIYOU
COUNTY AND
SOUTHWEST OREGON. CONVECTIVE CLOUDS ARE NOW FORMING EAST OF THE
CASCADES AND EXPECT THUNDERSTORMS TO DEVELOP THERE LATER TODAY.
THE 07/12Z MFR SOUNDING SHOWED A PW OF 1.01 INCHES...A LOT MORE THAN
YESTERDAY. MODIFIED FOR THE AFTERNOON HIGH YIELDS A CAPE OF 1847
J/KG...WHICH IS CONSIDERABLY JUICIER THAN YESTERDAY. THE SOUNDING
STILL SHOWS A MID LEVEL STABLE LAYER...BUT PROVIDES A VERY SMALL
NEGATIVE AREA...JUDGING FROM CURRENT ACTIVITY...IT HAS ALREADY MIXED
OUT.
THE CUTOFF LOW WILL MOVE THROUGH THE MEDFORD CWA TONIGHT AND EARLY
TUESDAY. EXPECT SCATTERED THUNDERSTORMS EVERYWHERE BUT THE COAST
THROUGH THIS EVENING. SHOWERS WILL COME TO AN END TUESDAY AS
WHAT IS LEFT OF THE CUTOFF DEPARTS TO THE EAST.
AFTER THAT...DRY SOUTHWEST FLOW ALOFT WILL MOVE OVER THE AREA AS AN
UPPER TROUGH SETS UP OFFSHORE TUESDAY. EXPECT DRY AND WARMER
WEATHER TUESDAY AND WEDNESDAY. THE TROUGH WILL MOVE ONSHORE
THURSDAY...AND IT WILL PUSH A COOL FRONT ONSHORE WITH IT. THE
07/06Z GFS IS STILL FORECASTING SOME LIGHT PRECIPITATION WITH THIS
SYSTEM...BUT STILL DONT BUY IT. THE FRONT WILL MANIFEST ITSELF AS
AN ONSHORE MARINE PUSH.
AFTER THE TROUGH PASSAGE...EVEN DRIER NORTHWESTERLY FLOW ALOFT WILL
DEVELOP OVER THE AREA. THE 07/06Z GFS SOLUTION WANTS TO PINCH OFF
WEAK CUTOFF LOW OFF THE CALIFORNIA COAST...BUT THIS LOW IS
CONSIDERABLY WEAKER THAN THE CURRENT ONE...DONT THINK IT WILL ACT
TO ADVECT TROPICAL MOISTURE INTO THE AREA. EXPECT CONTINUED DRY
WEATHER WITH TEMPERATURES EDGING BACK UP TO SEASONABLE VALUES AND
MAYBE WARMER BY EARLY NEXT WEEK.
&&
.AVIATION...INLAND...THUNDERSTORMS THIS EVEING INTO TUESDAY. SOME OF
THESE CELLS WILL PRODUCE HEAVY RAIN AND SMALL HAIL. CONDITIONS WILL
REMAIN VFR. COAST...ISOLATED THUNDERSTORMS THIS EVENING...AREAS OF
IFR VISIBILITIES AND CEILINGS IN LOW CLOUDS AND FOG BECOMING
ISOLATED AS MOST AREAS IMPROVE TO VFR TUESDAY AFTERNOON. AREAS OF
IFR WILL RETURN TO THE AREA TUESDAY NIGHT.
