AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
448 AM PDT FRI JUL 16 2010

.SYNOPSIS...
A DRY COOL FRONT WILL PASS THROUGH THE INLAND NORTHWEST TODAY AND
USHER IN SLIGHTLY COOLER TEMPERATURES AS WELL AND GUSTY WINDS. EXPECT
CONDITIONS TO REMAIN DRY WITH NEAR NORMAL TEMPERATURES THROUGH THE
WEEKEND. A SERIES OF WEAK STORM SYSTEMS WILL BEGIN IMPACTING THE
REGION MONDAY THROUGH MUCH OF THE WEEK BRINGING COOLER TEMPERATURES
AND A THREAT OF SHOWERS AND THUNDERSTORMS. PRECIPITATION WILL BE
CONFINED MAINLY TO THE MOUNTAINS MONDAY AND TUESDAY THEN STRONGER
SYSTEMS ARRIVING WEDNESDAY THROUGH FRIDAY WILL BEGIN INCREASING
THE THREAT FOR PRECIPITATION TO THE LOWLANDS AS WELL.

&&

.DISCUSSION...
TODAY AND TONIGHT...AN APPROACHING VORT MAX CURRENTLY NEAR VANCOUVER
ISLAND WILL MOVE INTO ERN WA/SRN BC TODAY...THEN E OF THE REGION
TONIGHT. THE DEEPENING MARINE LYR ALONG THE PAC NW COAST WILL
COMBINE WITH WARM TEMPS TODAY IN THE COLUMBIA BASIN TO GENERATE A
SIGNIFICANT CROSS- CASCADE TEMP AND PRESSURE DIFFERENCE THAT WILL
RESULT IN VERY GUSTY WINDS IN THE E SLOPES CASCADE GAPS. THIS IS
CERTAINLY AN ISSUE FOR THE ONGOING WILDFIRES...BUT HUMIDITY LEVELS
ARE SUCH THAT RED FLAG CONDITIONS WILL ONLY BE MARGINAL. WE'LL
HAVE TO WATCH THIS CLOSELY. FCST SOUNDINGS SHOW A SIGNIFICANTLY
DRY PROFILE THE NEXT 24 HOURS AND VERY LITTLE IN THE WAY OF
MEANINGFUL INSTABILITY. WE'VE THEREFORE KEPT THE FCST DRY FOR ALL
ZONES. THE ONLY NOTE OF UNCERTAINTY IS THE SBCAPE THE NAM PRODUCES
IN THE MTNS CLOSE TO THE BC BORDER...AND ALSO TO THE IMMEDIATE S
OF THE CAMAS PRAIRIE OF IDAHO. THOUGH THIS APPEARS
OVERDONE...WE'LL HAVE TO MONITOR THIS AS WELL. BZ

SATURDAY THROUGH THURSDAY...MODELS
IN FAIRLY GOOD AGREEMENT OF LARGE SCALE FEATURES...LIKE A GENERAL
TROUGHING OVER THE PAC NW THROUGH THE WEEKEND AND INTO NEXT WEEK.
SAT AND SUN THE WAVES THAT MOVE THROUGH ARE FAIRLY WEEK WITH
LITTLE TO NO MOISTURE ASSOCIATED WITH IT. NO MORE THAN JUST SOME
TRANSIENT HIGH LEVEL CLOUDS EXPECTED ACROSS THE NORTH. MONDAY
MODELS SHOW A BIT DEEPER TROUGH OVER THE AREA AND BY TUESDAY THE
GFS IS HINTING AT SOME MOISTURE MOVING UP THE SPINE OF THE
CASCADES FROM THE SOUTH. THE DEEPER TROUGH ACTUALLY MOVES THROUGH
THE FORECAST AREA DURING THE WED/THUR TIME FRAME. KEPT MENTION OF
SHOWERS AND THUNDERSTORMS EACH AFTERNOON IN THE FORECAST.
TEMPERATURES WILL BE AT OR SLIGHTLY BELOW AVERAGE READINGS THROUGH
THE FORECAST PERIOD.

&&

.AVIATION...
THE PRIMARY FOCUS WILL BE GUSTY WINDS LATER TODAY NEAR THE E SLOPES
OF THE CASCADES FOLLOWING THE PASSAGE OF THE DRY COLDFNT THIS
MORNING. THE MOST GUSTY WINDS WILL OCCUR MAINLY AFTER 21Z TODAY
AT KEAT...WITH GUSTS 22-27KTS BETWEEN 22Z-04Z. SMOKE FROM LOCAL
BRUSH FIRES WILL BE VISIBLE AT TIMES THROUGH THE FORECAST
PERIOD...BUT IS NOT EXPECTED TO HAMPER AIR OPERATIONS. A STEADY
DECREASE IN WIND SPEEDS CAN BE EXPECTED OVERNIGHT. BZ
