Area forecast discussion, Jul 1, 2:31 PM MST, 2 hours 3 minutes before
Area Forecast Discussion National Weather Service Tucson AZ 231 PM MST FRI JUL 1 2016 .SYNOPSIS...Moist conditions will give way to a drier and warmer pattern through early next week. Another round of monsoon moisture will begin working its way into the area late Tuesday into late next week. && .DISCUSSION...The combination of lingering monsoon moisture and an approaching mid/upper level trough led to an active day weather- wise across southeast Arizona. Showers and thunderstorms will linger into the evening hours for areas mainly southeast and east of Tucson, before quieter weather moves in for all areas overnight into the weekend. The approaching trough will nudge the remaining monsoon moisture to the east and south of the area this weekend into early next week. Mid range models are in agreement that high pressure will re-establish itself near the Four Corners area by mid week with moisture returning to Arizona. && .AVIATION...VALID THRU 03/00Z. Showers and thunderstorms will continue into early this evening mainly impacting the KOLS/KDUG terminals. Considerably fewer showers and thunderstorms on Saturday mainly for areas east of Tucson. Ceilings generally 8-10K ft with multiple cloud layers above. Gusty winds and brief MVFR conditions in heavy rainfall are likely near storms where wind gusts could exceed 30 kts. Otherwise surface winds generally 10 kts or less. Aviation discussion not updated for TAF amendments. && .FIRE WEATHER...Showers and thunderstorms mainly east and south of Tucson will subside this evening. Thereafter, moisture will begin to diminish across the region beginning Saturday and continuing through Tuesday, resulting in a decrease in the coverage of showers and thunderstorms and a slight bump up in afternoon temperatures. Some moisture will begin to return to the area Wednesday for a general increase in showers and thunderstorms once again. && .TWC WATCHES/WARNINGS/ADVISORIES... None. && Discussion...Cantin Aviation/Fire Weather...Lader Visit us on Facebook...Twitter...YouTube...and at weather.gov/Tucson
