.SYNOPSIS...An upper level low pressure system will track east
across northern Mexico this weekend. Moisture associated with this
low will reach into southern Utah, with some shower activity across
southern Utah Saturday. High pressure aloft will settle over the
Great Basin for the first half of the week, followed by a return
to an active weather pattern late in the week.

&&

.DISCUSSION...The well-defined upper low off the northern Baja
coast this evening is just about ready to make the turn east and
track across northern Mexico this weekend. Moisture continues to
stream north across eastern Arizona and up into the four corners
region. Clouds and pockets of light precip will persist across
southeast Utah overnight, then stretch back to the east across
extreme southern Utah Saturday/Saturday evening as the upper
tracks east across northern Baja then northwest Mexico.

Precip should finally end across southern Utah late Saturday night
Sunday as the remnant of the upper low breaks out into west Texas
Sunday. Still looking at lingering cloud cover Sunday, followed by
clearing skies from the north as the eastern Pacific upper ridge
rolls over into the Great Basin early in the upcoming week.

Dry/stable conditions with some valley fog and increasing urban
haze will exist under the upper ridge for the first half of the
week. The westerlies will break through late in the week,
bringing another round of active back to Utah.

&&

.AVIATION...VFR conditions will persist overnight with ceiling
generally running close to 7000 feet. A brief period of MVFR
conditions from fog off of the Great Salt Lake could develop early
Saturday morning. Ceilings will dissipate by early afternoon, with
mostly clear skies through the remainder of the TAF period.
