SOUTHWEST OREGON/NORTHERN CALIFORNIA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MEDFORD OR 230 PM PDT SAT JUN 02 2001 12Z ETA/MESOETA/NGM/AVN IN. MAJOR ONSHORE MARINE PUSH THIS MORNING WITH STRATOCUMULUS OVER MOST OF SOUTHWEST OREGON FROM THE COAST TO THE CASCADE CREST. SOME STRATUS HAS EVEN MADE IT OVER TO THE EAST SIDE IN NORTHERN KLAMATH COUNTY. MOSTLY CLEAR OVER THE REST OF SOUTHERN OREGON/NORTHERN CALIFORNIA. AN UPPER TROUGH IS CURRENTLY OVER THE FORECAST AREA WITH ONE MORE SHORT WAVE NOW MOVING INTO NORTHWEST OREGON. THIS WILL CAUSE THE TROUGH TO DIG A BIT DEEPER INTO EASTERN OREGON. DONT EXPECT MUCH FROM THIS SHORT WAVE OTHER THAN A GENERAL ENHANCEMENT OF WHAT IS HAPPENING NOW...AND MAYBE SOME DRIZZLE AND/OR A LIGHT SHOWER ALONG THE COAST...ENDING BY THIS EVENING. THE STRONGEST ONSHORE LOW LEVEL FLOW FOR THE NEXT SEVERAL DAYS WILL OCCUR THIS AFTERNOON AND EVENING. ONCE THAT FEATURE MOVES THROUGH THERE IS NOTHING BUT RIDGING FOR THE NEXT FEW DAYS. THE RIDGE IS NOT PARTICULARLY STRONG...IT IS QUITE FLAT BY THE TIME THE AXIS MOVES OVER THE FORECAST AREA MONDAY NIGHT. THE TIME SECTIONS SHOW SOME MIDDLE LEVEL CLOUDS MOVING THROUGH SUNDAY AND SUNDAY NIGHT WITH SOME WARM ADVECTION...SO WILL ADD THOSE TO THE FORECAST. OTHERWISE...EXPECT HIGH CLOUDS TO PERIODICALLY MOVE THROUGH THE RIDGE AND OVER THE FORECAST AREA. ALSO EXPECT A GENERAL DRYING AND WARMING TREND INLAND. ALONG THE COAST...THE MARINE LAYER SHOULD THIN OUT A BIT AS THE RIDGING FORCES THE MARINE INVERSION TO SUBSIDE. IT NOW LOOKS LIKE THE LOW LEVEL OFFSHORE FLOW SUNDAY NIGHT WILL BE MINIMAL...NOT ENOUGH TO KEEP THE MARINE LAYER OFFSHORE. EXTENDED...THROUGH FRIDAY...A STRONG UPPER RIDGE WILL BUILD OVER THE GREAT PLAINS WHILE A TROUGH DIGS OFFSHORE BETWEEN 130W AND 140W. HEIGHTS REMAIN HIGH OVER THE FORECAST AREA SO EXPECT DRY WEATHER WITH A SLOWLY INCREASING MARINE LAYER DURING THIS TIME. THE UPPER TROUGH WILL FINALLY MOVE ONSHORE SATURDAY...WEAKENING RAPIDLY AS IT DOES SO. THICKNESSES DO DROP ABOUT 30-60M AS IT MOVES THROUGH THOUGH...SO WOULD NORMALLY EXPECT THE MARINE LAYER DEPTH TO INCREASE...STRONGER ONSHORE FLOW...AND SLIGHTLY COOLER TEMPERATURES. HOWEVER...GUIDANCE INDICATES LITTLE CHANGE SO THE MAIN CHANGE MAY ACTUALLY OCCUR ON SUNDAY. GIVEN THE UNCERTAINTY...WILL GO WITH LITTLE CHANGE THROUGH THE EXTENDED PERIOD. STOCKTON .MFR...FROST WARNING...TONIGHT FOR ORZ029/030/031 AND CAZ084/085.
