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 30, 9:32 PM MST, 2 hours 28 minutes earlier.
Area Forecast Discussion National Weather Service Tucson AZ 932 PM MST Fri Jun 30 2017 .SYNOPSIS...Dry conditions will continue through Saturday night. Isolated to scattered afternoon and evening thunderstorms will then occur Sunday into next Friday. The bulk of thunderstorms will be east to south of Tucson. Daytime temperatures will generally be a few degrees above normal into next week. && .DISCUSSION...Clear skies across the area tonight. Current forecast looked in good shape, so no updates necessary this evening. Please refer to the additional sections for more details. && .AVIATION...Valid thru 02/06Z. Clear skies much of southeast Arizona into Saturday afternoon. The exception will be mainly southeast of KTUS where a few clouds above 15k ft AGL may occur. Surface wind Saturday afternoon wly/swly 10-15 kts with gusts to near 25 kts. Surface wind variable in direction less than 12 kts at other times. Aviation discussion not updated for TAF amendments. && .FIRE WEATHER...Dry conditions through Saturday. Daytime minimum relative humidity will generally range from 5-15 percent area-wide. Isolated to scattered afternoon and evening thunderstorms will then expected Sunday into next Friday. The bulk of these thunderstorms will be mainly east to south of Tucson. Thunderstorm outflows will create gusty and erratic winds at times, and there is the potential for new fire ignitions due to lightning. Otherwise, southwest to northwest afternoon winds at 10-15 mph are expected into early next week, with the strongest speeds northeast of Tucson and especially in the vicinity of Safford. && .PREV DISCUSSION...Broad upper ridge extends from well west of the southern California coast eastward into the southern CONUS this afternoon. This pattern will provide dry conditions through Saturday night. Various 30/12Z numerical prediction models then depict an upper pattern that will become more conducive to the development of showers and thunderstorms starting Sunday and continuing during the upcoming week. In essence, high pressure aloft is progged to become centered generally near the Four Corners region Tuesday and remain quasi- stationary over the central Rockies into the latter part of next week. There were differences amongst the various deterministic solutions and even between high resolution models such as the Univ of Arizona WRF-NAM and WRF-GFS regarding daily precip chance detail for this forecast area. As an example, the WRF-NAM was more aggressive versus the WRF-GFS regarding precip potential especially for the Tucson metro area Sunday afternoon/evening. As another example, the deterministic ECMWF was generally for robust with available moisture and liquid precip amounts versus the GFS through around the middle of next week. Thereafter, the GFS/ECMWF were quite similar regarding the depiction of better precip chances by next weekend. At any rate, only minor adjustments were made to the inherited gridded data PoPs through next Friday. In summary for this forecast period, expect isolated to scattered showers and thunderstorms, with the best precip chances east-to-south of Tucson. The bulk of these showers/tstms will occur during the afternoon and evening hours, although some showers/tstms may occur during the late night/early morning hours as well. High temperatures this forecast period will generally average at least a few degrees above normal. && .TWC WATCHES/WARNINGS/ADVISORIES...None. && Visit us on Facebook...Twitter...YouTube...and at weather.gov/Tucson
