Area Forecast Discussion National Weather Service Tucson AZ 935 AM MST Thu Jun 23 2022 .SYNOPSIS...Another reinforcing shot of moisture will result in more shower and thunderstorm activity across southeast Arizona today through the weekend. Thunderstorms today should affect areas from Sells to the New Mexico border. Some storms will generate strong erratic winds and locally heavy runoff producing rains. && .DISCUSSION...HIRES CAM solutions continue to depict a busier convection day today especially compared to yesterday. Basically more convection with a much earlier start, likely first over central Pima county around or shortly after noon. The question is how vigorous will the convection be. CAPE and shear values don't point toward wild storms however DCAPE is up there enough from mainly central Pima county northward toward Phoenix that a few strong outflows may be a problem. Of course over the lower deserts early in the season that could bring about blowing dust issues. Coordinated with Phoenix office (Thanks PHX) about possibility of including parts of the lower desert in Marginal severe area on SPC outlook. Will see on that, either way there is some threat of greater than 50 mph gusts that part of AZ. Other issue is precipitable water. It has dropped over the last 24hrs so the heavy rain threat is less, but it is just high enough west of Tucson with slow moving storms that local areas may have heavy rain and runoff. Not a great day for that given the marginal PW but will need to watch for training storms or those with little if any movement. && .AVIATION...Valid through 24/12Z. AFT 19Z, SCT SHRA/TSRA with SCT-BKN clouds 8-10k ft ABV valley floors. Lowering cloud bases in/around storms to FEW/SCT 4k-6k ft AGL with brief MVFR conditions possible. Erratic wind gusts in excess of 45 kts possible with storms and outflows. Otherwise, expect E-SE winds 5-15 kts through the period. Aviation discussion not updated for TAF amendments. && .FIRE WEATHER...Abundant moisture over the region on a steady monsoon flow pattern will result in high humidity levels and daily rounds of showers and thunderstorms into next week. There should be a notable uptick in storm coverage across the entire SE Zone this afternoon and evening. Due to the deep moisture in place, expect a good chance of wetting rains. && .PREV DISCUSSION... /issued 157 AM MST Thu Jun 23 2022/ Some showers were lingering across portions of Cochise county early this morning. Would expect this activity to dissipate by day break. Otherwise, models continued to depict more widespread shower and thunderstorm activity this afternoon and evening compared to Wednesday. Thereafter, the overall flow pattern remained favorable for daily chances of showers and thunderstorms. Models did point to Sunday as being a significant upswing in showers and thunderstorms. This uptick in activity will be in response to an upper low/inverted trough interacting with the deep moisture over AZ as it approaches from the east. Otherwise, high temperatures will hover near seasonable readings. && .TWC WATCHES/WARNINGS/ADVISORIES...
