Area Forecast Discussion
National Weather Service Flagstaff AZ
845 PM MST Fri Mar 24 2017

.SYNOPSIS...High pressure brought dry and warmer conditions to
northern Arizona today. The next trough of low pressure will cross
the state Saturday bringing slightly cooler temperatures and a
chance of rain showers mainly from Flagstaff northward. Fair
weather is expected Sunday, then another low pressure system will
arrive Monday into Tuesday.


A rather quiet weather night seems in store, with increasing high
cloudiness from west to east overnight and into the early
morning. Little change is anticipated this evening with regards to
the short-term forecast.


.PREV DISCUSSION /330 PM MST/...The next fast-moving trough of
low pressure will cross northern Arizona Saturday and Saturday
evening. High temperatures will drop back down several degrees
with a chance of showers developing mainly from Flagstaff
northward. Snow levels generally remaining above 7500 to 8000
feet with little or no accumulation expected. Fair weather returns
Sunday with daytime temperatures near to a few degrees above

A progressive pattern continues next week with a couple of storm
systems forecast to affect the region, one Monday into Tuesday
and another next Friday or Saturday. These systems are taking a
northwest to southeast track which is usually not the wettest for
us, but will definitely need to be watched. Models are not in very
good agreement (up to 24 hours off on timing) so confidence is
low. More details will be available in the next few days on these
systems so stay tuned.


.AVIATION...For the 06Z Package...A weather system passing through
northern AZ Saturday afternoon/evening will bring scattered SHRA
primarily from KFLG northward where local MVFR conditions will be
possible. SW winds increasing Saturday to 10-20G25-35KT through
the afternoon. Aviation discussion not updated for TAF amendments.
