FRONT EXTENDS FROM DESERT ROCK NORTHEASTWARD INTO UTAH ACROSS
MILFORD AND RICHFIELD THEN INTO NORTHWESTERN COLORADO.
MAIN FLARE-UP TONIGHT WILL BE ALONG THIS BOUNDARY. FLOW ALOFT PRETTY
MUCH PARALLEL WITH FRONTAL BOUNDARY...SO TRAINING ECHOES COULD BE A

FRONTAL BOUNDARY WILL GET SWEPT EASTWARD TOMORROW...WITH COLD POOL
SETTLING OVER THE STATE. 500MB TEMPS DROP TO -16C...SO GOOD
INSTABILITY. LIMITING FACTOR FOR CONVECTION TOMORROW WILL BE CLOUD

COOL AIR WILL HINDER SNOWMELT THIS WEEK...BUT DANGEROUS RISES STILL
A POSSIBILITY THROUGH FRIDAY DUE TO LOCALLY HEAVIER RAIN...ESPECIALLY
ACROSS CENTRAL UTAH. WARMUP OVER THE WEEKEND WILL GET SNOWMELT GOING
AGAIN.

&&
