DISCUSSION...SATELLITE IS SHOWING CLEARER SKIES WEST OF THE
CASCADES WITH FAIR WEATHER CUMULUS AND CIRRUS EAST AND IN NORTHERN
CALIFORNIA. THIS AFTERNOON IS TURNING TO BE SLIGHTLY ABOVE NORMAL
WITH MORE HIGHS IN THE 70S AND 80S INLAND WITH 60S AT THE COAST.
TO START THE WEEK OFF THERE WILL BE ANOTHER WARM UP IN OVERNIGHT
TEMPERATURES. STARTING TOMORROW, MORNINGS WILL HAVE 40S EAST, 50S
WEST AND MID-40S AT THE COAST. THIS WILL CONTINUE THROUGH MOST OF
THE WORK WEEK.
THROUGH THE DAY MONDAY A SHORTWAVE TROUGH WILL MOVE THROUGH. THERE
WILL BE A 3-6 DEGREE COOLDOWN FOR THE AFTERNOON. THE SHORTWAVE IS
ENOUGH TO BRING A RAIN CHANCE (15-20%) TO MORE OF LAKE AND KLAMATH
COUNTIES MONDAY AFTERNOON. THERE IS ALSO A PORTION OF EASTERN
SISKIYOU AND WESTERN MODOC COUNTIES THAT WILL BE UNDER A 15-20% RISK
IN THE AFTERNOON. THIS WILL ALSO BRING STRONGER WINDS NEARING 10-15
MPH, AND THEY WILL BE STRONGEST EAST OF THE CASCADES IN THE
AFTERNOON. A MARINE PUSH WILL BRING THE CHANCE FOR LIGHT RAIN CLOSER
TO SHORE TUESDAY NIGHT INTO WEDNESDAY MORNING.
LONG TERM: THE REAL CHANGE IN THE FORECAST COMES CLOSER TO NEXT
WEEKEND AS A LARGER TROUGH SWINGS SOUTHWARD. THERE IS MORE AGREEMENT
THAT TEMPERATURES WILL BE 5-15 DEGREES COLDER THAN NORMAL. RAIN IS
LOOKING TO RETURN FRIDAY AFTERNOON/NIGHT AND CONTINUE INTO THE
WEEKEND. AS THIS IS A WEEK OUT, WE WILL CONTINUE LOOKING AT THIS
EVENT THROUGH THE WEEK. -HERMANSEN
