AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
822 PM PDT MON JUN 25 2012

.DISCUSSION...HAD SOME THUNDERSTORMS ROLL THROUGH THE SOUTHERN
ROGUE VALLEY BETWEEN 5PM AND 6PM AND DUMP ANYWHERE FROM A TENTH TO
A HALF AN INCH OF RAIN. WE RECEIVED A REPORT FROM SOUTHWEST
MEDFORD OF A LARGE TREE STRUCK BY LIGHTNING WHICH EXPLODED.
THERE WAS VERY LITTLE WIND AND NO REPORTS OF HAIL WITH THE STORMS,
SO NOTHING SEVERE. WHILE LIGHTNING IS LIKELY DONE FOR THE NIGHT,
SHOWERS WILL PROBABLY LINGER MUCH OF THE NIGHT. RIGHT NOW, THE
MAIN BAND OF SHOWERS IS ROUGHLY 50 MILES EITHER SIDE OF THE
CASCADE CREST. THIS WHOLE THING WILL CONTINUE TO SLIDE EAST
THROUGH THE NIGHT AS THE UPPER LOW COMES ASHORE. IN ITS WAKE,
SHOWERS WILL BE MORE SCATTERED BUT WILL STILL BE POSSIBLE WITH THE
UPPER COLD POOL MOVING THROUGH. CURRENT FORECAST HAS THINGS
COVERED AND NOT PLANNING ANY UPDATES THIS EVENING. -WRIGHT

&&

.AVIATION...A BAND OF SHOWERS MOVING THROUGH THE CASACADES AND
EMERGING ONTO THE EAST SIDE THIS EVENING WILL CONTINUE TO SLIDE
EAST OVERNIGHT. MVFR CIGS ARE COMMON WITHIN THE BAND AND WE'VE HAD
OCCASIONAL IFR CIGS AND VIS IN MODERATE TO HEAVY SHOWERS. THE
UPPER LOW WILL MOVE THROUGH TONIGHT WITH SHOWERS BECOMING MORE
SCATTERED AT ALL LOCATIONS, BUT MVFR WITH PATCHY IFR CIGS WILL
LIKELY PERSIST THROUGH THE NIGHT. MOUNTAINS WILL REMAIN MOSTLY
OBSCURED THROUGH TONIGHT AS WELL. CONDITIONS WILL GRADUALLY BECOME
VFR AREA WIDE TOMORROW MORNING AS THE UPPER LOW MOVES EAST, EXCEPT
IN THE UMPQUA AND ALONG THE NORTH COAST WHERE MVFR WILL PERSIST
THROUGH LATE MORNING.

&&

.PREV DISCUSSION... /ISSUED 255 PM PDT MON JUN 25 2012/

DISCUSSION...LOW PRESSURE OFF THE OREGON COAST THIS AFTERNOON
WILL MOVE INLAND TONIGHT THEN SWING NORTHEAST OF THE CWA BY
TUESDAY MORNING. SHOWERS ALONG AND WEST OF THE CASCADES WILL
CONTINUE TO INCREASE IN COVERAGE THIS AFTERNOON AND EVENING. WITH
THE COLD CORE (-25C AT 500MB) MOVING INTO THE COAST THIS AFTERNOON
AND EVENING, THERE WILL BE ENOUGH INSTABILITY FOR SOME ISOLATED
THUNDERSTORMS TOO. CURRENT RADAR/LIGHTNING PLOTS SHOWING A CELL
OVER SOUTHERN DOUGLAS COUNTY PUTTING OUT SEVERAL BOLTS. SINCE FREE
AIR FREEZING LEVELS ARE QUITE LOW, DOWN AROUND 6500 TO 7500 FEET,
ANY OF THE STRONGER CELLS COULD CONTAIN SMALL HAIL/GRAUPEL. THE
LOW WILL TAKE ON A BIT OF A NEGATIVE TILT AS IT MOVES OVERHEAD
THIS EVENING AND OVERNIGHT. THIS MAY ALLOW CONVECTIVE ELEMENTS TO
ORGANIZE INTO A MORE WELL DEVELOPED LINE/AREA OF SHOWERS/STORMS,
ESPECIALLY NEAR THE CASCADES LATE THIS EVENING. THIS AREA WILL
THEN SHIFT EASTWARD ACROSS PORTIONS OF KLAMATH AND NORTHERN LAKE
COUNTIES OVERNIGHT. WITH WINDS ALOFT AT 10-18KFT IN THE 30-40KT
RANGE IN THESE AREAS, SOME STRONG WIND GUSTS MAY ACCOMPANY ANY
STORMS. BY TUESDAY MORNING, THE TROUGH AXIS WILL SHIFT TO THE
NORTH AND EAST OF THE AREA WITH JUST A FEW LINGERING SHOWERS
ACROSS FAR NORTHERN SECTIONS. DRIER AIR WILL ARRIVE TUESDAY
AFTERNOON AND CLOUDS WILL GIVE WAY TO INCREASING SUNSHINE.

WEDNESDAY WILL BE DRY AND WARMER WITH SUNSHINE FOR MOST
AREAS...EXCEPT SOME LOW CLOUDS ARE LIKELY TO BE NEAR COASTAL
AREAS IN THE MORNING. TEMPERATURES WILL AT LEAST GET BACK TO
WITHIN A DEGREE OR TWO OF NORMAL WITH HIGHS IN THE LOWER TO MID
80S HERE IN MEDFORD. ON THURSDAY, ANOTHER TROUGH UPSTREAM WILL
PUSH TOWARD THE OREGON COAST. THIS WILL PROBABLY BRING A BIT OF A
MARINE PUSH INTO COASTAL AREAS AND THE UMPQUA BASIN ALONG WITH A
SLIGHT CHANCE OF SHOWERS IN THE AFTERNOON, BUT IT SHOULD STAY DRY,
WARM AND SUNNY ELSEWHERE.

FRIDAY AND BEYOND...MODELS CONTINUE TO SHOW THE MEAN TROUGH
POSITION ALONG THE WEST COAST THIS WEEKEND WITH A MORE ZONAL FLOW
DEVELOPING ACROSS THE NORTH PACIFIC AND WEST-SOUTHWEST FLOW ALOFT
OVER THE MEDFORD CWA EARLY NEXT WEEK. THIS WILL MAKE TIMING OF
INDIVIDUAL DISTURBANCES DURING THIS TIME FRAME A TOUGH TASK, BUT
WE'RE NOT SEEING ANY REAL STRONG SYSTEMS IMPACTING THE CWA. WE'LL
MAINTAIN A BROAD BRUSH OF SLIGHT CHANCE TO CHANCE POPS ESPECIALLY
WEST OF THE CASCADES SATURDAY AND SUNDAY. ON SUNDAY, THERE IS A
SLIGHT CHANCE OF THUNDERSTORMS INDICATED OVER THE SOUTHEAST PART
OF THE CWA. TEMPERATURES WILL PROBABLY BE NEAR OR JUST SLIGHTLY
BELOW AVERAGE. -SPILDE/MAW
