.DISCUSSION...

MORE SHOWER AND THUNDERSTORM ACTIVITY IS EXPECTED THIS AFTERNOON
AND EVENING. LOWER LEVEL STEERING FLOW WILL HAVE A GREATER
PRESENCE TODAY...SO THUNDERSTORMS SHOULD BE A BIT MORE
PROGRESSIVE. WINDS ARE EXPECTED TO BE MAINLY LIGHT AND TERRAIN
DRIVEN THROUGH MIDDAY...BUT INCREASINGLY DOMINATED BY ERRATIC AND
GUSTY WINDS FROM NEARBY SHOWERS AND THUNDERSTORMS IN THE
AFTERNOON. CHANCES FOR SHOWERS AND THUNDERSTORMS WILL CONTINUE
WEDNESDAY...BUT SLIGHTLY WARMER AND DRIER AIR WILL WORK INTO THE
AREA THURSDAY.

AN ACTIVE PATTERN IS EXPECTED THROUGH THE WEEKEND...WITH A FEW
COLD TROUGHS PASSING BY THAT COULD BRING SNOW TO THE HIGHER
ELEVATIONS.

...THUNDERSTORMS IMPLY STRONG GUSTY AND ERRATIC WINDS...
...HAINES INDEX IS HIGH LEVEL HAINES BOTH DAY AND NIGHT...
