SHORTWAVE TROUGH MOVING EAST THROUGH THE NORTHERN ROCKIES ON TIME
WITH EARLIER MODEL RUNS.  THIS WAVE PROVIDING LITTLE IMPACT ON
EASTERN UTAH AND WESTERN COLORADO OUTSIDE OF A FEW MID/HIGH LEVEL
CLOUDS MOVING THROUGH THIS MORNING AND SLIGHT COOLING OF H7 TEMPS.
THIS COOLING WILL BE REFLECTIVE IN MAX TEMPS TODAY WITH READINGS
EXPECTED TO BE A FEW DEGREES COOLER IN MOST AREAS.  MODEL GUIDANCE
HAS TRENDED THIS DIRECTION...BUT LIKELY HAS COOLED THINGS OFF TO
MUCH WITH PLENTY OF SUN AGAIN EXPECTED AND FAIRLY WARM MINS THIS
MORNING.  SO PLAN ON GOING SLIGHTLY ABOVE GUIDANCE NUMBERS TODAY.
MID LEVEL FLOW STILL STRONG ENOUGH TO PRODUCE BREEZY AFTERNOON
WINDS...WHICH IS HANDLED WELL IN CURRENT FCST.  MORE OF THE SAME IN
STORE TUESDAY AS DRY FLOW ALOFT CONTS.

A LITTLE STRONGER WAVE NOW SHOWING UP IN MODELS FOR WEDNESDAY. THIS
WAVE FCST TO MOVE ACROSS WYOMING...WITH JUST ENOUGH ENERGY AND
MOISTURE TO POSSIBLY SPARK A FEW STORMS OVER THE NRN AND CENTRAL
MTNS.  CURRENT MENTION OF SLIGHT CHC POPS ON WEDNESDAY STILL LOOKS
GOOD AND WILL LEAVE AS IS.  REMAINDER OF THE WEEK RETURNS TO DRY AND
HOT AS WESTERN RIDGE SHIFTS EAST OVER THE ROCKIES...WITH RDG AXIS
FINALLY MOVING TO OUR EAST BY LATE IN THE WEEK.  THIS WILL ALLOW SOME
MOISTURE TO MOVE NORTH BY EARLY NEXT WEEK. STILL A LONG WAY TOw GO...
BUT IT IS A GLIMMER OF HOPE FOR SOME MEANINGFUL RAINFALL.

WESTERN COLORADO AND EASTERN UTAH EMERGENCY MANAGERS SHOULD MAINTAIN
A NORMAL LEVEL OF WEATHER AWARENESS TODAY.
