FOR EASTERN UTAH AND WESTERN COLORADO, HERE IS THE LATEST WEATHER
SYNOPSIS.

ISOLATED THUNDERSTORMS WILL BRING GUSTY OUTFLOW WINDS AND THE
POTENTIAL FOR A BRIEF PERIOD OF RAIN THIS EVENING, THEN STORMS WILL
SLOWLY DISSIPATE OVERNIGHT.

HIGH PRESSURE WILL SHIFT FROM THE GREAT BASIN SOUTHEASTWARD TO THE
FOUR CORNERS WEDNESDAY THROUGH FRIDAY WHICH WILL ALLOW FOR A DEEPER
SURGE OF SUBTROPICAL MOISTURE TO ROTATE NORTHWARD FROM THE DESERT
SOUTHWEST, LEADING TO AN INCREASE IN SHOWER AND THUNDERSTORM
ACTIVITY AND COVERAGE. LOCALLY HEAVY RAINFALL WILL BE POSSIBLE,
INCREASING THE POTENTIAL FOR FLASH FLOODING ACROSS MAINLY THE
SOUTHERN HALF OF THE REGION.
