Area Forecast Discussion
National Weather Service Flagstaff AZ
830 PM MST Mon Oct 24 2016

.SYNOPSIS...Expect scattered showers and thundertorms to move from
west to east tonight as low pressure moves through the northern
Great Basin. Dry and warmer conditions will develop on Tuesday and
continue for the next several days.


Area radars show a line of showers and tstorms now along a line from
Page to Prescott, and this line is moving to the east. A second and
smaller area of precip is seen over srn Gila county and this area
moving to the northeast. No changes to the short term forecast.


.prev discussion 328 pm...Showers and thunderstorms have sprouted up
across northern Arizona this afternoon, mainly north of I-40 thus
far. Expect that areas of storms will continue into the overnight
hours, before ending from west to east early Tuesday. As high
pressure develops from Tuesday afternoon and the following few days,
dry conditions with well above normal daytime temperatures will
again dominate the weather across the Grand Canyon State. Extended
range models indicate that a trough may brush the northern portions
of AZ from late Friday into the weekend. Current indications are
that the majority of the associated moisture and instability will
remain just north of the AZ, but enough uncertainty remains for some
slight chance mentions of precipitation during that time frame for
now. In all, daytime temps will remain above normal through the 7-
day forecast.


.AVIATION...For the 06Z forecast...Scattered shower bands and
thunderstorms will continue to move across northern Arizona during
the overnight period. Shower activity will diminish by mid morning
on Tuesday. Locally heavy rain producing MVFR/IFR possible in
stronger storms. VFR conditions after 18z. Aviation discussion not
updated for TAF amendments.
