NWS Tucson, AZ wrote its last area forecast discussion before the first event at Jul 21, 1:51 PM MST, 4 hours 39 minutes earlier.
Area Forecast Discussion National Weather Service Tucson AZ 151 PM MST Thu Jul 21 2022 .SYNOPSIS... Very hot temperatures in the forecast for Friday - approaching some records - with an uptick of monsoonal activity this weekend and into next week. && .DISCUSSION... The mesoscale convective system (MCS) that moved through northern Sonora Mexico last night has weakened, but residual cloud cover and a few isolated showers remain. The 12z sounding from Tucson was very moist, with precipitable water values over 1.8 inches and moisture throughout the column. Instability was over 1000 J/kg...quite unstable. The challenge for today is that there are several capping inversions notable in the sounding which may make it more challenging for convection to get going. SPC HREF members continue to highlight convection starting over the White Mountains / Mogollon Rim early this afternoon, and the best chance of thunderstorms remaining mainly south of east of Tucson. Additionally, an Excessive Heat Warning is in effect for the western portions of the CWA through tomorrow evening. Based on the latest guidance, we went ahead and added Zone 509 to the EHW. Regardless, daytime highs in some areas may approach record values. The record for Tucson is 108, and that's what we have in as our forecast high. Looking ahead past Friday, a more favorable monsoon pattern will take shape as a subtropical high settles in over the four corners region. Saturday and Sunday will likely be more active days, with widespread moisture becoming more prevalent. This will likely shift the impacts to more of a flooding threat. With more monsoon activity, daytime high temps will gradually return to more normal values. && .AVIATION... ISOLD-SCT SHRA/TSRA progged to develop again aft 21/19z, first over the White Mountains and the border region in Cochise County and east of KOLS in Santa Cruz County. Activity then spread west to southwest but generally remains south and east of KTUS, gradually diminishing aft 22/04Z. Lower cigs between 6-10k ft MSL can be expected around precipitation, including gusty winds up around 40 kts. Otherwise, cloud bases range 10-15k ft MSL with diurnal sfc winds generally less than 12 kts. Aviation discussion not updated for TAF amendments. && .FIRE WEATHER... Temperatures will remain several degrees above average trough Friday with daily thunderstorm chances. Storms become more widespread this weekend into next week as moisture increases area-wide, providing a greater potential for heavy rainfall. Strong and erratic outflow winds accompany the stronger storms, with otherwise diurnal wind trends. && .TWC WATCHES/WARNINGS/ADVISORIES... Excessive Heat Warning from 11 AM to 8 PM MST Friday for AZZ501- 502-504-505-509. && Public...Dang Aviation...Singer Fire Weather....Dang Visit us on Facebook...Twitter...YouTube...and at weather.gov/Tucson
