.SYNOPSIS...A MILD WESTERLY FLOW ALOFT WILL PREVAIL THROUGH THE
REMAINDER OF THE WEEK. A PAIR OF WEAK SYSTEMS WILL AFFECT THE
REGION DURING THE UPCOMING WEEKEND.

&&

.DISCUSSION...A MILD WEST-NORTHWESTERLY FLOW ALOFT PREVAILS ACROSS
THE REGION THIS EVENING. A WEAK FRONTAL BOUNDARY LEFT IN THE WAKE
OF A WAVE WHICH CROSSED THE NORTHERN ROCKIES YESTERDAY REMAINS

FEW DEGREES OFF DAYTIME MAXES THIS AFTERNOON. DESPITE THIS
COOLING...MAX TEMPS STILL RAN ROUGHLY 10 DEGREES ABOVE CLIMO

BIT...AHEAD OF AN APPROACHING UPPER LOW WHICH IS CURRENTLY
SPINNING OFF THE CA COAST. THIS LOW WILL CROSS THE DESERT
SOUTHWEST DURING THE DAY SATURDAY. INCREASING MOISTURE COMBINED

AFTERNOON/EVENING CONVECTION ACROSS MUCH OF THE AREA...WITH THE
GREATEST COVERAGE OVER THE SOUTH.

A COLDER NORTHERN STREAM SHORTWAVE IS STILL FORECAST TO DIG SOUTH
THROUGH THE FORECAST AREA SATURDAY NIGHT INTO SUNDAY. DIFFERENCES
REMAIN BETWEEN THE GFS AND EC REGARDING HOW FAR WEST THIS WAVE
DIGS...WITH THE EC REMAINING THE STRONGER...COLDER SOLUTION
