NOT CHANGE UNTIL LATER WEDNESDAY. WINDS WILL INCREASE A LITTLE
TODAY AS EVIDENT IN THE HIGHER CLEARING INDICES. WEAK PIECES OF
ENERGY WILL SLIP THROUGH UTAH FROM TIME TO TIME OVER THE NEXT FEW
DAYS BUT ONLY SERVE TO PRODUCE A FEW CUMULUS CLOUDS OVER HIGHER
TERRAIN. WINDS ON WEDNESDAY WILL TURN WEST AS A VERY WEAK SYSTEM
IS EXPECTED TO MOVE THROUGH NORTHERN ARIZONA ON THURSDAY. THIS
SYSTEM WILL ALSO BE WEAK AND WILL ONLY HELP TO ENHANCE CLOUDS.
