AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
301 PM PDT MON JUL 25 2011

.DISCUSSION...CU FIELD IS POPPING UP WHERE THE MODELS INDICATE
GREATEST INSTABILITY. HOWEVER...WITH THE STRONG 700 MB
FLOW...THESE CELLS ARE MOVING RAPIDLY NORTHEAST AND OUT OF OUR
AREA BEFORE THEY GROW ENOUGH TO PRODUCE ANY THUNDER. GOOD MARINE
PUSH FILLS MOST OF THE WEST SIDE WITH LATER ONSET TO HEATING UNTIL
THE CLOUDS BURN AWAY GIVING US SLIGHTLY COOLER TEMPS OVER MOST OF
THE REGION. UPPER RIDGE NUDGES INTO THE REGION WEDNESDAY...WITH
RAISING HEIGHTS...DEEPENING THERMAL TROUGH ALONG THE COAST AND
INCREASING OFFSHORE FLOW. TEMPERATURE WILL CLIMB RAPIDLY
THURSDAY...WITH INCREASES OF 5 TO 10 DEGREES ACROSS THE REGION
FROM WEDNESDAY. IN THE COASTAL WATERS THE DEEPENING THERMAL TROUGH
AND OFFSHORE FLOW WILL BRING WATERS TO GALES LATE TUESDAY AND
STRONG GALES BY THURSDAY. ALTHOUGH IT APPEARS THE THE REGION IS IN
AN UPPER TROUGH THE LATTER PART OF THE WEEK...HEIGHTS REMAIN HIGH
THROUGHOUT. THIS PATTERN REMAINS THROUGH THE WEEKEND WITH THE
MODELS INDICATING THAT MONSOONAL MOISTURE STARTS TO WRAP AROUND
INTO OUR REGION...BUT WILL WAIT UNTIL WE GET CLOSER TO THAT TIME
FRAME BEFORE WE BEGIN TO ADVERTISE FOR THIS...CONSIDERING THE PAST
SEVERAL DAYS.

&&

.AVIATION...IFR STRATUS RETURNS TO MOST OF THE COAST SHORTLY AFTER
MIDNIGHT WITH MVFR DECK MOVING INTO THE UMPQUA BASIN. THIS DECK
WILL BURN BACK OFFSHORE BY LATE MORNING.
