Area Forecast Discussion National Weather Service Tucson AZ 313 PM MST Mon Aug 7 2023 .SYNOPSIS...Somewhat more typical monsoon weather is expected this week with temperatures running closer to normal with scattered afternoon and evening thunderstorms across much of southeast Arizona. Drying out over the weekend and heating back up again Sunday into early next week. && .DISCUSSION...Scattered strong to severe thunderstorms developed rather quickly after 1230 pm mainly across Cochise county with lots of nickel to quarter size hail reports. These storms possibly being aided by a very weak upper level disturbance that was near Nogales this afternoon.days for scattered showers and thunderstorms each day through at least Thursday. Not every will see rain but those that do, could be locally heavy. Outside of Cochise county its pretty quiet even with the significant increase in moisture over the past 24 hours. Most recent CAMS showing different solutions on what might occur over the next 6-10 hours. Some runs have strong outflow moving out of Sonora MX and developing elevated storms as far north as Phoenix. Others do not. Thus went with a blend of models, leaning toward the NBM, with scattered storms this evening into early Tuesday morning. Moisture hanging around for most the week with Tuesday and Wednesday likely being the more active days. Interesting to note that the mid-level remnants of TS Eugene will move into southern California Thursday. Low-grade monsoon forecast Friday into the weekend. Temperatures this week will remain several degrees above normal before starting to warm up a bit over the weekend. Models suggesting a return to excessive heat levels with record or near record highs early next week under another strong high over the state. && .AVIATION...Valid through 09/00Z. SCT -SHRA/-TSRA for much of the valid period with storms developing either along outflow boundaries thru 08/10z and then again after 08/19z due to daytime heating. Erratic wind gusts to 45 kts with any -TSRA. Otherwise SFC winds NW-WLY 10-15 kts gusting up to 25 kts thru 08/03Z and once again after 09/18z. At other times winds will follow diurnal trends and generally remain under 10 kts. Aviation discussion not updated for TAF amendments. && .FIRE WEATHER...Daily rounds of showers and thunderstorms each afternoon through the weekend. Any storms that do form are capable of producing erratic and gusty outflows. Daytime temperatures remain a few degrees above normal before increasing this upcoming weekend into early next week. Minimum RH in the lower elevations range from 20-35% and 40-50% in the higher elevations today and decreasing to 10-20% and 20-30% by the weekend. && .CLIMATE...The consecutive day streak of highs 100 degrees or hotter in Tucson now stands at 53 days. The probabilities thru Friday of NOT hitting 100 degrees is less than 10% each day. Looking ahead to early next week, the most recent probabilities for hitting 110 degrees in Tucson is between 10% and 20%. && .TWC WATCHES/WARNINGS/ADVISORIES...None. && Visit us on Facebook...Twitter...YouTube...and at weather.gov/Tucson
