TUCSON - A series of storm systems are set to arrive over the next 7-10 days.
The first storm system clips Southeastern Arizona today, according to 4WARN Meteorologist Jeff Beamish. This feature cranks up the Sonoran Wind Machine this evening. Easterly wind gusts up to 25 MPH are possible overnight through Friday afternoon.
Daytime highs to wrap the work week peak in the upper 60s to low 70s.
Storm system #2 is slated to swing into Arizona on Sunday. While there is significant model disagreement regarding precipitation, there is a slight chance of valley rain/snow above 6,000 feet. Gusty winds redevelop Sunday afternoon with highs only reaching the low 60s.
Another storm system heads our way Sunday. GFS/Euro/U of A models at odds over rain/mt. snow chances. Better agreement on the return of cooler temps & breezes. #azwx #KVOAwx pic.twitter.com/nqxDmHlk8b— Jeff Beamish (@jeffbeamish) December 14, 2017
This second storm system drops lows early next week into the upper 30s to low 40s.
Long range computer models hint at third storm system possible late next week. Details remain unclear this far out.
