BY A COUPLE OF WEAK WEATHER DISTURBANCES CROSSING THE REGION
WEDNESDAY THROUGH FRIDAY.

.DISCUSSION...THE UPPER LOW IS ELONGATING E-W FROM CENTRAL CA TO
NWRN AZ THIS EVE AND THE PORTION OVER UT IS BECOMING MORE OF A

NOTED NEAR PARLEYS AND PROVO CANYONS BUT ARE NOT EXPECTED TO GET
ANY STRONGER.

NEAR NORMAL LEVELS. NEWLY SNOW COVERED AREAS OF SRN UT COULD
STRUGGLE TO WARM VERY MUCH HOWEVER.
