821 AM MST TUE NOV 17 2009

.DISCUSSION...HIGH PRESSURE WILL REMAIN OVERHEAD TODAY...CONTINUING
CALM...STABLE CONDITIONS. AS A RESULT...TERRAIN DRIVEN WINDS WILL
PREVAIL...AND CLEARING INDICES WILL BE QUITE LOW. WINDS WILL
INCREASE SOMEWHAT TOMORROW FROM THE SOUTHWEST AHEAD OF AN
APPROACHING WEAK SYSTEM. THESE WINDS...COMBINED WITH COOLING
TEMPERATURES ALOFT SHOULD ACT TO IMPROVE CLEARING INDICES.
HOWEVER...THERE IS SOME QUESTION AS TO WHETHER THE WINDS WILL BE
SUFFICIENTLY STRONG TO COUNTER THE STABLE AIR.  A WEAK FRONT WILL
CROSS THE BURN AREA THURSDAY MORNING. THERE IS VERY LITTLE MOISTURE
WITH THE FRONT...AND PRECIPITATION IS NOT EXPECTED TO ACCOMPANY THE
FRONT. CALM...STABLE CONDITIONS RETURN THURSDAY AS A  SHORT-LIVED
RIDGE BUILDS OVERHEAD. A MUCH STRONGER FRONT WILL MOVE ACROSS THE
AREA SATURDAY. SOUTH WINDS WILL INCREASE SIGNIFICANTLY FRIDAY AHEAD
OF THE FRONT.
