The local office's own words before this special weather statement went out, 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 this special weather statement went out at Jul 23, 9:10 PM MST, 4 hours 3 minutes earlier.
Area forecast discussion, Jul 23, 9:10 PM MST, 4 hours 3 minutes before
Area Forecast Discussion National Weather Service Tucson AZ 910 PM MST Sat Jul 23 2022 .SYNOPSIS...Temperatures will fall back to near average this weekend into next week as moisture increases and thunderstorms become more likely. Upcoming storms will carry an increasing flash flood threat along with strong winds and lightning. && .UPDATE...Convection was slow to get going this afternoon, but we've slowly seen an uptick in activity across portions of the forecast area, including the Tucson metro area, since 8 pm. After mining all the new 00z to 02z CAM data it looks like the area will see a very active overnight period. Main threats overnight will be strong gusty winds and brief heavy rain that may lead to some flash flooding problems. Went ahead and made a quick update to the forecast to account for above thinking. && .DISCUSSION...Looking at a slight delay in the development of showers and thunderstorms today. However, still expecting a few strong thunderstorms with locally heavy downpours and strong winds late this afternoon and evening. Will also likely see some lingering showers and thunderstorms overnight as well. The best chance of thunderstorms and heavy rainfall will be near the International Border today. Ensembles favored a wet weather pattern evolving through next week as deeper moisture advects into the region and a couple of disturbances interact with this moisture to produce more widespread rainfall chances. Latest WPC Excessive Rainfall Outlook products highlighted a slight risk of excessive rainfall the next 4 days. Although, isolated flash flooding will be possible later today, especially the near the International Border, more widespread rain chances will be possible Sunday into Monday. The latest HREF solutions zero in on Sunday afternoon and evening with neighborhood probabilities for 3hr QPF greater than one inch exceeding 50 percent. Based on this latest model guidance, have opted to post a flash flood watch for Sunday afternoon and evening. Will need to play future watch issuances day-to-day as deep moist convection can be somewhat fickle this time of year based on the extent of morning cloudiness and subsequent daytime surface heating. Otherwise, daytime temperatures will lower to near seasonable readings this coming week. && .AVIATION...Valid through 25/00Z. Isolated to Scattered TSRA. Localized +TSRA likely. Lower cigs between 5-8k ft AGL can be expected around precipitation, including gusty winds in excess of 40 kts. Otherwise, cloud bases range 8-12k ft AGL with diurnal sfc winds generally less than 12 kts. Aviation discussion not updated for TAF amendments. && .FIRE WEATHER...Increasing moisture will bring more widespread showers and thunderstorms, providing a greater potential for heavy rainfall. Most locations should see at least a wetting rain into next week, with many locations seeing areal averages greater than one half inch. Strong and erratic outflow winds accompany the stronger storms, with otherwise diurnal wind trends. && && .TWC WATCHES/WARNINGS/ADVISORIES... Flood Watch from Sunday afternoon through Sunday evening for AZZ502>515. && Visit us on Facebook...Twitter...YouTube...and at weather.gov/Tucson
