Area Forecast Discussion National Weather Service Tucson AZ 300 PM MST Mon Jul 13 2020
SYNOPSIS. Another day of hot weather is expected before temperatures begin to ease back toward normal levels. There is enough moisture around for isolated to scattered thunderstorms this evening, then diminishing a bit Tuesday. The thunderstorm coverage should increase again for Wednesday and beyond.
DISCUSSION. Storm activity has been slow to get going, even across Graham and Cochise county where they've seen more sun today. From Tucson west, its been quite thanks to a very well defined MCV which moved through this morning. Afternoon visible satellite and regional radar showed this feature was near Florence and had weaken/filled. On the temperature side, its been cooler than Sunday, thanks to a weakened upper high and cloud cover, but still seeing a few spots near Excessive Heat criteria. Thus will let the Excessive Heat Warning run out to 8 pm.
Tonight: generally isolated to low scattered coverage of storms mainly east and southeast of Tucson.
Tuesday: southwest flow aloft will relegate afternoon/evening storms to mainly Cochise county and the White mountains.
Wednesday into next weekend: A general ramp up of daily thunderstorm activity as the area gets into a more active monsoon pattern. There will be, however, daily variability in areal coverage of storms. An easterly wave passing by to our south late in the weekend into early next week could enhance thunderstorm chances or not depending on cloud cover.
With the high weakening and taking up a position to our east, daily highs will gradually cool as the week progresses and be slightly above normal this weekend. Ahh. Nice.
AVIATION. Valid through 15/00Z. SCT-BKN 10-15k ft MSL with SCT-BKN layers above expected through much of the forecast period. Isolated to scattered SHRA/TSRA expected this afternoon mainly east of KTUS, then again Tuesday afternoon but limited to Santa Cruz/Cochise Counties and the White Mountains. Outside of TSRA outflows, light and variable surface winds mainly less than 10 kts with the exception of WLY/NWLY 8-12 kts in the afternoon hours with gusts around 20-25 kts. Aviation discussion not updated for TAF amendments.
FIRE WEATHER. With monsoonal flow in place, expect isolated to scattered showers and thunderstorms each afternoon/evening through the forecast period. The pattern becomes slightly less favorable on Tuesday keeping storms to areas mainly southeast of Tucson and over the White Mountains. Activity looks to ramp back up the second half of the week into next weekend. Temperatures will ease back to slightly above normal levels as the week progresses. Relative humidities hold close to average through the week with generally good overnight recoveries. 20-ft winds generally remain less than 15 mph with afternoon gusts, although today and Tuesday will be breezier across the Upper Gila River Valley. Also, any afternoon/evening thunderstorms will capable of gusts of 45+ mph.
CLIMATE. The low temperature this morning at the Tucson Intl airport was a very warm 89 degrees. If this holds at the end of the day, it will tie July 22, 2006 as the all-time warmest daily low temperature on record.
Additionally, today marks the 7th straight day with a daily low in the 80's for Tucson. This sets a new consecutive day record for July (old July record 6 days in 2996 and 2017) and is two days shy of the calendar record of 9 days set in 2017.
On an obscure climate record note for Tucson, with the current high of 104 degrees as of 3 pm, this would be the largest one day drop in high temperature for all of the 21 dates in which the high temperature was 113 degrees or hotter. Previous record is 8 degrees in 1990 (113 on June 28 to 105 degrees on June 29).
TWC WATCHES/WARNINGS/ADVISORIES. Excessive Heat Warning until 8 PM MST this evening for AZZ501>509-515.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
