...FIRE WEATHER WATCH IN EFFECT FROM SUNDAY AFTERNOON THROUGH

.DISCUSSION...
UPPER LEVEL HIGH PRESSURE OVER EASTERN NEW MEXICO THIS EVENING WILL
BE SHIFTING INTO TEXAS ON SATURDAY WHICH WILL PULL SOME MID LEVEL
MOISTURE INTO SOUTHWEST COLORADO BY THE AFTERNOON. THIS MOISTURE
WILL LEAD TO ISOLATED THUNDERSTORM DEVELOPMENT OVER THE REGION AS
TEMPERATURES REMAIN WELL ABOVE NORMAL. THE MAIN THREAT FROM THESE
STORMS WILL BE THE GUSTY OUTFLOW WINDS...AND THIS MAY OCCUR NEAR
VIRGA SHOWERS WITH VERY DRY CONDITIONS NEAR THE SURFACE. WINDS SHOULD
GENERALLY BE TERRAIN DRIVEN OVERNIGHT THROUGH MID MORNING BEFORE
MIXING INCREASES AND TURNS WINDS MORE TO THE SOUTHWEST. SOME WINDS
GUSTS UP TO 25 MPH WILL BE POSSIBLE AWAY FROM THUNDERSTORMS AS WELL.
