328 PM MST Mon Oct 24 2016

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


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 00Z 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 TSRA. Aviation discussion not updated for TAF
