.DISCUSSION...HIGH PRESSURE PREVAILS OVER THE AREA WEDNESDAY
WITH WARM TEMPERATURES AND DRY WEATHER. A THERMAL TROUGH ALONG
THE COAST WILL LEAD TO EASTERLY MIXING WINDS BUT SURFACE WINDS
WILL BE MAINLY SLOPE DRIVEN. THE THERMAL TROUGH IS EXPECTED TO
MOVE INLAND IN THE AFTERNOON AND CROSS THE BURN AREA AROUND 1400.
THIS WOULD LEAD TO TRANSPORT WINDS TO TURN MORE WESTERLY WITH
HUMIDITY DROPPING INTO THE UPPER TEENS BRIEFLY IN THE LATE
AFTERNOON. TEMPERTURE ON THURSDAY WILL BE SLIGHLY COOLER WITH
SLIGHLY HIGHER HUMIDITY AS THE UPPER LEVEL RIDGE SHIFTS EAST. THIS
WILL ALLOW A MORE WESTERLY JETSTREAM TO MOVE INTO SOUTHERN OREGON

MOVE INLAND NEXT WEEKEND WITH MEASURABLE RAIN LIKELY FOR JOSEPHINE
COUNTY.
