AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
233 AM PDT TUE AUG 19 2008

.SYNOPSIS...
SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE TODAY FOR MAINLY
NORTH IDAHO...AND WILL ACCOMPANY COOLER TEMPERATURES. A DEEP AND
UNUSUALLY STRONG UPPER LEVEL TROUGH WILL MOVE OVER THE INLAND
NORTHWEST BY WEDNESDAY...BRINGING WET WEATHER AND COOLER THAN
NORMAL CONDITIONS TO THE AREA THROUGH THURSDAY.

&&

.DISCUSSION...
TODAY AND TONIGHT...THE FOCUS WILL BE ON THUNDER AREAL COVERAGE
THROUGH THIS EVENING. THOUGH THE MAIN VORT MAX THAT HELPED TO
PRODUCE THE WIDESPREAD THUNDER MON HAS HAS WEAKENED AND LIFTED N
INTO SRN BC...THE REMNANTS OF THE COLDFNT ALOFT REMAIN IN THE VCNTY
OF N ID SLOWLY MOVING E. WATER VAPOR LOOP SHOWING THE SHEARING
VORT MAX OVER OREGON ATTM...ON THE ERN EDGE OF THE UPPER TROF
ALONG THE PAC NW COAST... WILL MOVE INTO ERN WA THIS MORNING AND
LIKELY BE A FACTOR IN REGENERATING SOME SHOWERS ALONG THE W SIDE
OF THE AFOREMENTIONED COLDFNT. BY LATER TODAY...GUIDANCE IS STILL
SHOWING SFC-BASED INSTABILITY SUFFICIENT TO PRODUCE ANOTHER LTG
THREAT FOR NE WA AND N ID...THOUGH MUCH LESS INTENSE THAN MON.
WEVE EXTENDED THE RED FLAG WARNING INTO THIS EVENING FOR N ID TO
TAKE INTO ACCOUNT THIS THUNDER THREAT. THERE IS STILL SOME UNCERTAINTY
AS FAR AS AREAL COVERAGE OF THE THUNDER THREAT FOR NE WA...AND
EVEN THE N CASCADES LATER TODAY...SO WELL DROP THE WARNINGS FOR
THOSE ZONES THIS MORNING. WINDS TODAY DONT LOOK STRONG ENOUGH THE
PRODUCE A MAJOR THREAT TO ONGOING WILDFIRES. BZ

WEDNESDAY THROUGH MONDAY...CONTINUED TRANSITION INTO A VERY WET
AND COOLER PERIOD AS A MOISTURE PLUME WITH A WELL MAINTAINED TAP
INTO SUB-TROPICAL MOISTURE CONTAINING REMNANTS OF FORMER WEST
PACIFIC TROPICAL STORM VONGFONG PASSES THROUGH BRINGING THE
POTENTIAL OF MODERATE RAINFALL. MODEL RUNS HAVE OSCILLATED WITH
THE MAXIMUM PRECIPITABLE WATER CONTAINED IN THE IMPINGEMENT AREA
OF THE PLUME ALONG THE NORTHERN CALIFORNIA AND OREGON COAST FOR THE
MOST PART BETWEEN 1.5 AND 2 INCHES. THEREFORE A STABLE RAIN
SPREADING FROM WEST TO EAST TRANSITIONING TO INSTABILITY SHOWERS
WITH PERHAPS ANOTHER MINOR MENTION OF THUNDERSTORMS AT TIMES INTO
WEDNESDAY NIGHT REMAINS VALID. LATER ON WEDNESDAY NIGHT INTO
THURSDAY A COLD CLOSED LOW PRESSURE AREA IN TO WHICH THE MOISTURE
TAP/PLUME IS WRAPPED INTO SAGS SOUTHEAST AND BECOMES THE
INFLUENCER OF SENSIBLE WEATHER AS ITS COLD POOL ALOFT POSITIONS
OVER THE AREA...LOWERING THE TROPE AND SNOW LEVEL...AND INCREASING
THE INSTABILITY. CONTINUED MENTION OF SHOWERS WITH SOME
THUNDERSTORMS PEPPERED IN WITH THE MAX DAYTIME HEATING OVER
MOUNTAIN AREAS. THE EXPECTATION IS THAT IF THUNDERSTORMS OCCUR AT
ALL THE THEY WILL BE OF THE VERY SHALLOW PULSE TYPE AND WET.
MOUNTAIN SNOW MENTION IN THE FORECAST THURSDAY ABOVE 7000 FEET
MSL...IT MAY FALL IN A VERY WET AND SLOPPY MANNER AT THIS
ELEVATION BUT IT WILL NOT ACCUMULATE FOR LONG IF AT ALL AS THE
CURRENT SURFACE SOIL TEMPERATURES DO NOT SUPPORT IT...MOSTLY
LIKELY WILL FALL AS GRAUPEL OR SOFT HAIL WITH FLEETING RESIDENCE
TIME ON THE GROUND. THE COLD CLOSED LOW TAKES ITS TIME EXITING
WITH THE WESTERN FRINGE INFLUENCING THURSDAY NIGHT INTO EARLY
FRIDAY MORNING UNTIL RIDGING THAT MOVES IN FROM THE WEST TAKES
HOLD AND AMPLIFIES ALLOWING A RETURN TO DRIER AND WARMER WEATHER
AT LEAST INTO SUNDAY. MONDAY IS UNCERTAIN AT THIS POINT AS THE
RIDGE AXIS MOVES EAST AND OPENS UP THE DOOR FOR EITHER A WET
FRONTAL PASSAGE OR SHORTWAVES UNDERCUTTING THE RIDGE AHEAD OF THE
WET FRONTAL ZONE WHICH WOULD FIRE OFF CONVECTIVE SHOWERS. FORECAST
TEMPERATURES SHOW TRACE OUT THE ABOVE SCENARIO WITH A COOLING
TREND THAT BOTTOMS OUT THURSDAY...FOLLOWED BY A WARMING TREND
THEREAFTER THAT BECOMES MORE PRONOUNCED WITH THE RIDGE
AMPLIFICATION OVER THE WEEKEND. /PELATTI

&&

.AVIATION...
PREDOMINATELY VFR CONDITIONS EXPECTED AT ALL SITES THROUGH 06Z
WEDNESDAY. AN UPPER LEVEL TROUGH MOVING THROUGH THE REGION WILL
KEEP CONDITIONS UNSETTLED WITH A CONTINUED CHANCE OF RAIN AND
SOME THUNDERSTORMS OVERNIGHT TONIGHT AND INTO TUESDAY...BUT THE
THREAT FOR STRONGER STORMS WILL BEGIN TO SHIFT PRIMARILY INTO THE
PANHANDLE EASTWARD.
