The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Tucson, AZ wrote its last area forecast discussion before the first event at Jun 18, 2:04 PM MST, 2 hours 6 minutes earlier.
Area Forecast Discussion National Weather Service Tucson AZ 204 PM MST Sat Jun 18 2022 .SYNOPSIS...A strong increase in moisture will bring increasing thunderstorm chances over the next several days. Some storms will generate strong erratic winds and locally heavy rain. && .DISCUSSION...Extensive cloud cover with isolated showers and a few thunderstorms early this morning had delayed the surface heating needed for the redevelopment of activity this afternoon. However, recent satellite imagery was showing some promising breaks in this cloudiness which should help trigger more showers and thunderstorms through tonight. Thereafter, models were in good agreement with shifting the low pressure trough to our west today a little farther east on Sunday which will focus the best chance of showers and thunderstorms just east and southeast of the greater Tucson area. Residual moisture will keep the chance of showers and thunderstorms in the forecast next week, mainly during the afternoon and evening hours. After a lull in the activity on Monday, models favored an upswing in the areal coverage of showers and thunderstorms Tuesday into next weekend. Thanks to more cloudiness and rain chances, high temperatures will hover near normal readings through at least Tuesday before gradually warming the remainder of the week. && .AVIATION...Valid through 20/00Z. SFC winds will be out of the S/SW 7-12 kts outside of thunderstorms. TSRA/SHRA chances increase through tonight before diminishing in areal coverage Sunday morning. Thereafter, redevelopment of TSRA/SHRA can be anticipated Sunday afternoon with most of the activity confined east and south of KTUS. Cloud decks will be SCT/BKN 10k ft AGL, lowering in/around showers/storms to FEW/SCT 3k- 6k ft AGL with brief MFR conditions possible. Erratic wind gusts in excess of 40kts possible with storms and outflows. Aviation discussion not updated for TAF amendments. && .FIRE WEATHER...An anomalously early moisture surge will bring increasing chances for thunderstorms over the next several days. Will see the most widespread rain chances across much of the area through early Sunday. Best storm chances will shift primarily south and east of the Tucson Metro next week. Strong outflow winds with storms and even with heavier showers could lead to erratic fire behavior. && .TWC WATCHES/WARNINGS/ADVISORIES...None. && Visit us on Facebook...Twitter...YouTube...and at weather.gov/Tucson
