AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
855 AM PDT SUN SEP 9 2007

.UPDATE...STRATUS ASSOCIATED WITH WEAK SOUTHERLY FLOW IN THE THERMAL
TROUGH IS PROGRESSING UP TO GOLD BEACH AT THIS TIME. EXPECT MUCH OF
COASTAL CURRY COUNTY TO BE IN THE MARINE AIR IN WEAK ONSHORE FLOW
THROUGH THE DAY AND LOOKS LIKE CURRENT HIGH TEMP FCST THERE MAY BE A
BIT WARM. INLAND... OBSERVATIONS AND UPPER AIR REPORT OVER MEDFORD
SHOWS AREAS ABOVE 2500 FT MSL HAVE WARMED 5 TO 9 DEGREES VERSUS
YESTERDAY MORNING. OFFSHORE FLOW BLOWING PRETTY GOOD WITH EASTERLY
GUSTS TO 25 MPH OVER THE CASCADES. WILL RAISE INLAND TEMPS OVER
MAINLY THE WESTERN 2/3 OF THE FA 2 TO 4 DEGS IN THE UPDATE AND
ACCOUNT FOR MORE LOW CLOUD IN THE SOUTHERN COASTAL WATERS. MTS

&&

.PREVIOUS DISCUSSION...LATER THIS AFTERNOON SURFACE PRESSURE
TIGHTENS RIGHT ALONG THE CASCADES TONIGHT AND ALONG THE SOUTHERN
OREGON COAST. RIDGETOP WINDS WILL REMAIN WINDY OVER NIGHT PREVENTING
TEMPERATURES FROM DROPPING TOO MUCH...AND KEEPING RH RECOVERIES VERY
POOR. DO NOT EXPECT RED FLAG CONDITIONS WITH THE OFFSHORE FLOW...
HOWEVER WILL HAVE HEADLINES IN THE FIRE WEATHER FORECAST.

HAVE TRENDED TEMPERATURES A LITTLE WARMER TODAY OVER YESTERDAY.
H85 TEMPERATURES RISE A DEGREE OR TWO OVER THE AREA TODAY AND
TREND EVEN WARMER MONDAY INTO TUESDAY. IT LOOKS LIKE TUESDAY WILL
STILL BE THE WARMEST AS MAX TS GET INTO THE MID 90S WITHIN SOME
OF THE VALLEYS WEST OF THE CASCADES WITH TEMPERATURES REACHING TO
THE UPPER 80S IN SOME PLACES EAST.

THE REX BLOCK THAT HAS BEEN DOMINATING THE WEATHER PATTERN OF THE
PAST FEW DAYS WILL BEGIN TO BREAK DOWN MONDAY. ALSO THE THERMAL
TROUGH DISSIPATES AND FLOW TRANSITIONS TO ONSHORE. AFTER TUESDAY
TEMPERATURES WILL RELAX...AND SO WILL THE RIDGETOP WINDS. THE
LINGERING LOW FROM THE REX BLOCK SHIFTS NORTHEAST IN RESPONSE TO
THE SUBTROPICAL JET THAT MOVES THROUGH CENTRAL CALIFORNIA. GFS HAS
BEEN FORECASTING THE CLOSED TO LOW TO PUSH UP AGAINST THE OR/CA COAST
LINE LATE NEXT WEEK. SINCE IT IS SO FAR INTO THE EXTENDED
FORECAST...HAVE LEFT SILENT POPS IN THE LATE FORECAST.

.AVIATION...AREAS OF MVFR AND PATCHY IFR IN FOG ALONG THE CURRY
COAST SHOULD PREVAIL WITH SOME THINNING THROUGH THE DAY. INLAND
AREAS VFR.
