AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
241 AM PST SAT DEC 7 2013
.DISCUSSION...A COLD UPPER LEVEL TROUGH IS CENTERED OVER EASTERN
OREGON THIS MORNING AND MOVING OFF RAPIDLY TO THE EAST. AN UPPER
LEVEL RIDGE OF HIGH PRESSURE CENTERED ALONG 140W PUTS A NORTHERLY
FLOW OVER THE AREA. THIS FLOW HAS LOST THE OVER WATER PATH SO IT IS
MUCH DRIER. THERE WILL BE A FEW LINGERING SHOWERS ASSOCIATED WITH
THE EXITING TROUGH, MAINLY EAST OF THE CASCADES, UNTIL ABOUT MID DAY
TODAY. THEN THE COLD, DRY AIR MOVES IN. CLOUD COVER WILL RAPIDLY
CLEAR TODAY. THE CLEARING SKIES COMBINED WITH THE FRESH SNOW COVER
ON MOST AREAS WILL ALLOW A GREAT DEAL OF LONGWAVE RADIATION TO SPACE
TONIGHT. THIS WILL MAKE THE OVERNIGHT LOWS PLUMMET TO THE LOWEST
LEVELS IN MANY YEARS. TEMPERATURES IN KLAMATH, LAKE AND MODOC
COUNTIES WILL BE BITTERLY COLD, WELL BELOW ZERO. IN THE LATE
AFTERNOON TODAY AND INTO THE EARLY EVENING, MUCH OF LAKE COUNTY WILL
SEE NORTH WINDS OF 10 TO 15 MPH THAT WILL CREATE A WIND CHILL AS LOW
AS -31 DEGREES. TEMPERATURES ON THE COAST WILL REMAIN BELOW FREEZING
UNTIL MID DAY SUNDAY.
TEMPERATURES WILL MODERATE EARLY NEXT WEEK AS THE UPPER FLOW TURNS
MORE NORTHWESTERLY. ON LATE TUESDAY, A WEAK SYSTEM WILL BRUSH BY TO
THE NORTH TO BE FOLLOWED BY A STRONGER SYSTEM LATE WEDNESDAY AND
INTO THURSDAY. SNOW LEVELS WITH THIS SYSTEM WILL BE AROUND 5000
FEET. LOVEGROVE
&&
.AVIATION...MOSTLY MVFR CONDITIONS WITH ISOLATED IFR CONDITIONS...
ALONG WITH WIDESPREAD MOUNTAIN OBSCURATION...WILL CONTINUE
THROUGH THE EARLY MORNING. IFR CONDITIONS WILL LIKELY BECOME MORE
PREVALENT AROUND SUNRISE WITH FREEZING FOG EXPECTED TO FORM IN
WEST SIDE VALLEYS. VFR CONDITIONS ARE EXPECTED AT THE COAST LATER
THIS MORNING...AND AT LEAST PARTIAL CLEARING WILL OCCUR FROM WEST
TO EAST DURING THE DAY AS A DRIER AIR MASS MOVES IN...WITH
MOUNTAIN OBSCURATION DECREASING THIS AFTERNOON. SOME REDUCTION TO
VISIBILITY IS POSSIBLE EAST OF THE CASCADES IN BLOWING SNOW.
FREEZING LEVELS WILL REMAIN AT THE SURFACE FOR MOST LOCATIONS
TODAY AND TONIGHT IN A VERY COLD AIR MASS. SK
