Area Forecast Discussion
National Weather Service Flagstaff AZ
253 PM MST Mon Mar 19 2018

.SYNOPSIS...Dry weather and warming temperatures are forecast
through mid week, with increasing clouds by late Tuesday and
Wednesday. On Thursday and Friday, gusty southwest winds and good
chances for mainly rain showers are forecast as the next low
pressure system impacts the area. Fair weather is expected to
return for the weekend.


.DISCUSSION...A ridge of high pressure will be the main weather
feature over northern Arizona for the next few days. This will
promote dry conditions, above normal temperatures, and light
winds. Cloud cover will be on the increase late Tuesday into
Wednesday as a large plume of subtropical moisture streams into
southern California/Nevada. The moisture will eventually slide
south and east into northern Arizona late Thursday into Friday as
a weak trough crosses the region. Expect gusty southwest winds and
increasing chances of showers in association with this feature.
However, precipitation type will mainly be in the form of rain as
snow levels remain around 8,000 ft. A return to dry weather with
slightly above normal temperatures looks to be on the way for next


.AVIATION...For the 00Z package...Look for VFR conditions over
the next 24 hours. Light winds generally less than 10 kts. Aviation
discussion not updated for TAF amendments.


.FIRE WEATHER...High pressure moving into the southwest will bring
dry and warmer weather with light winds through Wednesday. However,
clouds will be on the increase from Tuesday into Wednesday in
advance of approaching Pacific moisture. Ventilation will be fair
to good each afternoon.

Thursday through Saturday...Expect increasing southwest winds and
moisture across Arizona as a weather system moves across the area
toward the end of the week. Thursday and Friday will see the best
chance for rain showers, along with gusty southwest winds.
Temperatures cooling to near normal.
