.SYNOPSIS...A weak weather disturbance will deliver cooler
temperatures and breezy to windy conditions this weekend, along
with a chance of showers tonight into Sunday. Some light snow is
possible above around 6500 feet elevation. Breezy and dry weather is
expected Monday through Wednesday, before more unsettled
conditions develop for the end of next week.

&&

.DISCUSSION...Gusty winds persist today as a trough moves onto
the west coast. Southwest winds 15-25 mph with gusts 30-40 mph are
forecast this afternoon and early evening. Temperatures today will
be a few degrees cooler, with increasing clouds by afternoon. The
trough will bring an increase in deeper moisture from west to
east by late afternoon through mid evening with a few showers
developing. Showers increase in coverage by late evening and
overnight due to large scale lift and upslope flow, leading to a
50-80% chance of showers by early Sunday morning. Colder air with
the trough will bring snow levels as low as 6500 feet by early
Sunday morning, with only light accumulation generally less than
1" currently forecast, and 2-5" over the highest peaks. Instability
appears low but an isolated thunderstorm can`t be ruled out
through Sunday afternoon. Much cooler temperatures arrive Sunday
with highs 10-15 degrees below normal. Sunday is also looking
windy as the trough passes, and gusts of 40-55 mph are likely
from the Mogollon Rim/White Mtns northward. A Wind Advisory has
been issued for these areas from 5 AM to 8 PM MST Sunday.

Monday through Wednesday - drier and warmer weather is expected
as the trough moves east of the state. By Thursday and Friday -
another low from off the Pacific could impact the state and bring
another chance of showers/t-storms. There is a quite a bit more
spread in the ensemble data with this one, so timing and precip
amounts are uncertain. Right now, our forecasts have the highest
precip chances on Thursday at 30-40%.
