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 Aug 14, 1:33 PM MST, 4 hours 7 minutes earlier.
Area Forecast Discussion National Weather Service Tucson AZ 133 PM MST Sun Aug 14 2022 .SYNOPSIS... Showers and thunderstorms will be possible each day this week. A slight downward trend in storm activity will occur by Tuesday or Wednesday before ramping back up the second half of the week into the weekend. Temperatures remain near seasonal averages for the next several days. && .DISCUSSION... Much of the area was clearing by late morning, but that still put surface heating 3 to 7 degrees behind yesterday early this afternoon. Slow development as expected with isolated mainly mountain storms so far. That will change over the next few hours, but with slower development and a continued modest shear environment, we will probably see less overall coverage compared to yesterday. Weak steering level flow with locally heavy rain still the main concern. Precipitable water values are back down closer 1.5 inches around Tucson, with lower values east and higher west. That will be a trend to watch for the first half of the week with HREF ensembles pushing PW values down closer to 1 inch in far eastern areas over the next 36 hours. That will put more of focus across far southern and eastern areas for the bulk of our precip chances by Tuesday. That will change by mid week as a strong easterly wave pushes from it's current location near far southern Texas across northern Mexico and into northern Sonora / southeast Arizona by Wednesday. NAEFS mean integrated water vapor transport shows a solid easterly signal by late Tuesday afternoon, with a strong and wet pattern building back in for the second half of the week. More wet microburst activity with an interesting CAPE/shear profile on the northern periphery of the wave Wednesday afternoon into Thursday that suggest organized convection. Should then make for an elevated monsoon forecast through the weekend. && .AVIATION...Valid through 16/00Z. SCT-BKN clouds at 8k-11k ft AGL thru 15/05Z and again aft 15/19Z, with diminishing clouds between 15/05Z and 15/17Z. ISOLD-SCT SHRA/TSRA developing and persisting thru 15/04Z and then developing again aft 15/19Z. With the stronger TSRA, expect cloud decks to lower to 4k-7k ft AGL, wind gusts to 45+ kts, vsby reductions and mountain obscurations. Outside of any TSRA, SFC wind generally less than 10 kts and favoring a WLY/NWLY direction in the afternoon/early evening hours and variable in direction at other times. Aviation discussion not updated for TAF amendments. && .FIRE WEATHER...Expect a daily chance of showers and thunderstorms through the upcoming weekend. The main threats will be strong gusty winds and heavy rainfall/flash flooding. There is the potential for precipitation outside the normal afternoon/evening cycles. Outside of thunderstorm outflows, wind trends will be light and follow typical diurnal patterns. && .TWC WATCHES/WARNINGS/ADVISORIES... None. && Meyer/Zell Visit us on Facebook...Twitter...YouTube...and at weather.gov/Tucson
