AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
445 PM PDT FRI JUL 30 2010

.SYNOPSIS...
AN UPPER LEVEL TROUGH WILL MOVE INTO THE REGION LATE TONIGHT
THROUGH SATURDAY...AND USHER IN MORE SEASONAL TEMPERATURES...A
CHANCE OF THUNDERSTORMS AND BREEZY WINDS TO THE INLAND NORTHWEST.
THE COOLER AND SHOWER WEATHER WILL PREVAIL NEXT WEEK...WITH THE
BEST CHANCES OF SHOWERS AND THUNDERSTORMS REMAINING IN THE
MOUNTAINS.

&&

.DISCUSSION...
FOR TONIGHT...THE INLAND NORTHWEST WILL REMAIN IN A MOIST
SOUTHWEST FLOW WITH A UPPER LEVEL TROUGH DIGGING DOWN THE COAST.
CONVECTION IS CURRENTLY FIRING ON THE RIDGE TOPS. ONCE THE CAP
BREAKS...THIS ACTIVITY WILL YIELD TO ISOLATED TO SCATTERED
THUNDERSTORMS THROUGH THE EVENING HOURS. THE BEST SURFACE BASED
INSTABILITY LOOKS TO BE ACROSS NORTHEAST WASHINGTON WITH CAPES
OVER 1200 J/KG AND LI'S TO -3. PWATS OVER A QUARTER OF AN INCH OF
MOISTURE WILL LEAD TO RATHER WET STORMS WITH BRIEF DOWNPOURS...SMALL
HAIL AND GUSTY WINDS POSSIBLE IN THE STRONGER CELLS. MID LEVEL
LAPSE RATES REMAIN STEEP OVERNIGHT...WHILE THE WAVE IN THE BASE OF
THE UPPER LEVEL TROUGH MOVES INLAND. A GOOD SWATH OF DIV OF Q IS
NOTICEABLE AHEAD OF THIS WAVE PUSHING FROM NORTH CENTRAL OREGON
INTO THE COLUMBIA BASIN BY 12Z SATURDAY. THIS COUPLED WITH MID
LEVEL MOISTURE AND INSTABILITY HAVE THE POTENTIAL FOR ANOTHER
ROUND OF THUNDERSTORMS OVERNIGHT...AND HAVE RAISED POPS ACROSS THE
REGION OVERNIGHT. MEANWHILE...THE SURFACE PRESSURE TROUGH FROM THE
WESTERN BASIN TO THE OKANOGAN VALLEY WILL SHIFT EAST...AND ALLOW
FOR LOCALLY BREEZY WESTERLY WINDS DOWN THE CASCADE VALLEYS AND
GAPS OVERNIGHT.

BY SATURDAY AND SATURDAY NIGHT...THE UPPER LEVEL TROUGH AND
EMBEDDED SHORTWAVE MOVE SLOWLY OVER THE FORECAST AREA...LEADING
TO A VERY ACTIVE PERIOD. THE THREAT OF CONVECTION WILL SHIFT FROM
ELEVATED TO SURFACE BASED BY THE AFTERNOON AND EVENING HOURS...WHILE
THE LOW LEVEL THETAE RIDGE PIVOTS ACROSS NORTHEAST WASHINGTON AND
NORTH IDAHO. PLENTY OF SURFACE BASED INSTABILITY TO LEAD TO A GOOD
CHANCE OF THUNDERSTORMS ACROSS THE REGION. WITH THE AMOUNT OF
SHEER ALOFT...THERE IS ALSO A SLIGHT CHANCE OF SEVERE ACTIVITY
FROM NORTH CENTRAL IDAHO INTO THE CENTRAL PANHANDLE AND ACROSS
WESTERN MONTANA. COOLER AND MORE SEASONAL TEMPERATURES ARE
EXPECTED AS THE SURFACE PRESSURE TROUGH SHIFTS EAST AND ALLOWS FOR
INCREASED WESTERLY WINDS ACROSS THE COLUMBIA BASIN INTO NORTH
IDAHO.

FOR SUNDAY THROUGH MONDAY...THE UPPER LEVEL TROUGH FILLS AND THE
REMAINS OF THE SHORTWAVE LINGER OVER NORTHEAST WASHINGTON BEFORE
DRIFTING ALONG THE CANADIAN BORDER INTO MONTANA...AND THIS LEAVES A
BAGGY TROUGH OVER THE REGION. THE REMNANTS OF THE SHORTWAVE WILL
PROVIDE THE FOCUS FOR ADDITIONAL CONVECTION AND PRECIPITATION
THROUGH THE PERIOD. THE GFS AND NAM EVEN IDENTIFY A WEAK
DEFORMATION BAND THAT FORMS AND ROTATES ACROSS THE NORTHEAST
CORNER OF WASHINGTON AND THE NORTHERN TIP OF IDAHO...LEADING TO
COOLER AND SHOWERY WEATHER. ELSEWHERE WILL CONTINUE TO SEE
SEASONAL TEMPERATURES. BY MONDAY AFTERNOON...A SECONDARY SHORTWAVE
DROPS INTO WESTERN WASHINGTON AND HELPS CONTINUE THE DIURNAL
DEVELOPMENT OF CONVECTION ACROSS THE NORTHERN MOUNTAINS. /RFOX.

MONDAY NIGHT THROUGH FRIDAY..MODELS IN FAIRLY GOOD AGREEMENT OF AN
UPPER LEVEL LOW MOVING DOWN FROM CANADA AND SETTING UP ACROSS THE
PAC NORTHWEST THROUGH MOST OF NEXT WEEK. THE LOW REMAINS NEARLY
STATIONARY THROUGH THURSDAY...LOCATED ACROSS SOUTHWEST BC/NW
WASHINGTON. LIGHTNING CLIMATOLOGY SUGGESTS THE BEST CHANCE FOR
SHOWERS AND THUNDERSTORMS UNDER THIS PATTERN WILL BE ACROSS THE
OKANOGAN HIGHLANDS...NORTHEAST MOUNTAINS AND THE NORTH ID
PANHANDLE. IF MODELS CONTINUE TO COME MORE IN LINE WITH ONE
ANOTHER WITH REGARDS TO SHORTWAVE FEATURES AND OVERALL PLACEMENT
OF THE LOW...ADDITIONAL SHOWERS AND THUNDERSTORMS MAY NEED TO BE
ADDED TO THE WATERVILLE PLATEAU NORTHEAST TOWARDS GRAND COULEE
DAM. MODELS SUGGEST THE LOW OPENING UP TO AN OPEN WAVE BY FRIDAY
AND BEGINNING ITS TRACK ACROSS THE INLAND NORTHWEST. TEMPERATURES
THROUGH THE PERIOD WILL BE AT OR SLIGHTLY ABOVE AVERAGE FOR THIS
TIME OF THE YEAR. /NISBET

&&

.AVIATION...
A SIGNIFICANT AMOUNT OF LIGHTNING IS EXPECTED ACROSS CENTRAL AND
EASTERN WASHINGTON AS WELL AS NORTH IDAHO BETWEEN AROUND 09Z
SATURDAY AND 00Z SUNDAY.  THROUGH 09Z...ISOLD TSRA IS EXPECTED
MAINLY OVER THE MOUNTAINS.  THEN THUNDERSTORMS WILL INCREASE AS AN
AREA OF LOW PRESSURE SLOWLY APPROACHES AND TRACKS THROUGH THE AREA.
GUSTY WINDS WILL LIKELY OCCUR WITH THUNDERSTORMS IMPACTING THE TAF
SITES.  BUT THE DETAILS OF WHEN THUNDERSTORMS MOVE THROUGH IS
UNCLEAR FOR ANY GIVEN SITE SO VCTS WAS USED WITH NO MENTION OF GUSTY
WINDS FOR NOW.  JW
