Can You Say, 'Snow in October'?

16 October 2018   Dr. Curtis James
It might snow tonight - at least in the surrounding hills.

Kiddos, don't count on school closures tomorrow. 

Weather Discussion:

Remnant moisture from what used to be Hurricane Sergio brought considerable shower activity this past weekend, especially in the Phoenix area, where 1”-2” of additional rainfall was reported. We are now only halfway through October, and it has been the wettest month of October on record for Phoenix.

Still another round of possible light to moderate rain showers is on tap for the Prescott area again tonight to tomorrow. This is due to the fact that an upper-level cold core low currently directly over Central Arizona will circulate relatively moist air from the east across the area and produce periods of lifting. Rainfall totals will most likely be in the 0.25”-0.50” range, and it will be breezy and cold. Areas above 6,000’ are expected to experience snow, and Flagstaff is expecting 2-4” of accumulation tonight to tomorrow morning.

Unsettled weather is on tap for Wednesday and Thursday as the low slowly rotates towards the east, with only a very slight chance of lingering showers, but most of the activity will be east of us. Improving conditions on Friday, but another weak cutoff low is expected to develop along the coast of Southern California this weekend and circulate moist, unstable air back into the state…with another chance for showers or thunderstorms Saturday to at least Monday of next week.
