.DISCUSSION...
WEAK ENERGY WILL BE SHIFTING OVERHEAD AS THE UPPER RIDGE OF HIGH
PRESSURE TO THE WEST BUILD BACK IN ACROSS WESTERN COLORADO. THIS
ENERGY AND LIMITED MOISTURE WILL TRIGGER ISOLATED SHOWERS ACROSS
THE HIGHER TERRAIN OF THE SAN JUANS. WIND GUSTS FROM THESE SHOWERS
OR VIRGA ALOFT WILL NEED TO BE MONITORED...OTHERWISE WINDS SHOULD
TURN FROM TERRAIN DRIVEN TO THE NORTH/NORTHWEST AT 5 TO 10 MPH
AS MIXING BEGINS AROUND NOON. WITH THE UPPER RIDGE BUILDING IN
TOMORROW SMOKE DISPERSAL CONDITIONS COULD BECOME A CONCERN BUT
THIS AFTERNOON MIXING SHOULD STRONG ENOUGH TO REACH GOOD LEVELS.
