Area forecast discussion, Aug 21, 8:53 AM PST, 2 hours 2 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPOKANE WA 953 AM PDT THU AUG 21 2008 .SYNOPSIS... AN UNUSUALLY DEEP UPPER LEVEL LOW PRESSURE SYSTEM WILL REMAIN OVER THE INLAND NORTHWEST THROUGH LATE TODAY....BRINGING WET...BREEZY...AND COOL CONDITIONS TO THE AREA. WARMER TEMPERATURES AND DRY CONDITIONS ARE EXPECTED FOR THE WEEKEND AS UPPER RIDGING TRIES TO BUILD INTO THE REGION. && .DISCUSSION... WATER VAPOR IMAGERY SHOWS UPPER LOW SPINNING OVER SOUTHERN BC BUT MOVING EASTWARD AT A FAIRLY GOOD CLIP. SEVERAL MINOR VORT LOBES ROTATING AROUND THIS LOW BUT THE MAIN ONE WELL BE CONCERNED WITH IS CURRENTLY OVER THE NORTHERN CASCADES. RADAR ECHOES ARE ALREADY INCREASING IN ASSOCIATION WITH THIS VORT LOBE. MORNING SUNSHINE IS ALLOWING THE ATMOSPHERE TO DESTABILIZE WITH -20C COLD CORE AT 500MB LAPSE RATES ARE DECENTLY STEEP. PATTERN IS MORE SIMILAR TO APRIL OR MAY RATHER THAN AUGUST. THE CURRENT SPEED OF THIS VORT LOBE IS A LITTLE TOO FAST TO REALLY MAXIMIZE ITS LIFT WITH THE AFTERNOON HEATING. AS SUCH THE CONVECTION WONT BE AS EFFICIENT AS IT COULD HAVE BEEN IF THIS VORT MAX WERE 3-6 HOURS SLOWER. ALSO THE DIV-Q PROGS FROM BOTH MODELS SHOW THE LARGER SCALE LIFT IS CURRENTLY MAXIMIZED OVER OUR AREA RIGHT NOW...AND BY THIS AFTERNOON IT WILL BE MOVING INTO WESTERN MONTANA WITH STRONG SUBSIDENCE/SINKING IN ITS WAKE. THIS WILL HINDER CONVECTIVE DEVELOPMENT AND LIMIT THE TOPS OF THE CONVECTION. AS SUCH WELL SEE WIDESPREAD SHALLOW CONVECTIVE SHOWERS THROUGH THE REMAINDER OF THE DATA WITH ISOLATED THUNDERSTORMS. AS USUAL THE MAIN ACTIVITY WILL BE OVER THE NORTHERN/EASTERN MOUNTAINS WHERE THE COLD POOL ALOFT IS LOCATED AND UPSLOPE LIFT WILL AID THE CONVECTION. I DONT EXPECT ANY OF THESE THUNDERSTORMS TO BECOME SEVERE. SHOWER ACTIVITY SHOULD SHUT DOWN VERY QUICKLY THIS EVENING AS THE DYNAMICS MOVE WELL EAST OF OUR AREA. AS SKIES CLEAR AND WINDS DECREASE WERE IN FOR A FAIRLY CHILLY NIGHT. WILL BE ADDRESSING THIS MORE WITH THE AFTERNOON DISCUSSION. RJ && .AVIATION... WIDESPREAD SHOWER AND ISOLATED THUNDERSTORM ACTIVITY IS EXPECTED OVER THE AREA EAST OF REPUBLIC TO KALW TODAY...WITH JUST ISOLATED SHOWERS TO THE WEST OF THIS LINE. SOME MVFR CONDITIONS ARE POSSIBLE WITH THESE SHOWERS ALONG WITH SOME SMALL HAIL. SHOWERS WILL QUICKLY DIE OFF THIS EVENING GIVING WAY TO CLEARING SKIES. SOME VALLEY FOG IS POSSIBLE OVER THE NORTHERN/EASTERN VALLEYS BY FRIDAY 12Z. FOG IS ALSO POSSIBLE AS THE KGEG/KSFF/KCOE SITES FRIDAY MORNING BUT THIS WILL DEPEND ON HOW MUCH RAIN WE RECEIVE IN THE SPOKANE METRO AREA TODAY. RJ && .PRELIMINARY POINT TEMPS/POPS...
