Area Forecast Discussion
National Weather Service Tucson AZ
254 AM MST TUE JUL 26 2016

.SYNOPSIS...Adequate moisture will provide scattered mainly
afternoon and evening thunderstorms into this weekend. Perhaps some
decrease in coverage will occur around Thursday. Expect hotter than
average daytime temperatures through Thursday followed by
moderating temperatures by early next week.

&&

.DISCUSSION...A thunderstorm complex continued to expand early this
morning across northern Mexico, with a few showers lingering across
far southeast Arizona. Otherwise, debris cloudiness will gradually
diminish through mid-morning before scattered showers and
thunderstorms redevelop this afternoon. The upper high will be
centered near the four corners region today, then amplify and become
positioned over southern Nevada by Thursday. Both of these locations
of the upper high typically favor an increase in daily thunderstorm
activity across the state. High temperatures will remain a few
degrees above normal even though more clouds and better rain chances
can be expected this week.

&&

.AVIATION...VALID THRU 27/12Z.
Isolated convection east of KTUS will diminish early this morning
with residual debris cloudiness between 10-12k feet this morning.
Another chance of thunderstorms will occur this afternoon and into
this evening with the best chances being near the mountains and
along the border including KOLS/KDUG terminals.Brief wind gusts to
45 kts and MVFR conditions are possible with the stronger TSRA.
Otherwise, sfc wind mainly less than 10 kts. Aviation discussion not
updated for TAF amendments.

&&

.FIRE WEATHER...Isolated to scattered mainly afternoon and evening
showers and thunderstorms will occur into this weekend. Outside of
gusty thunderstorm outflow winds, 20-foot winds will generally be
westerly to northwesterly at less than 15 mph during the afternoons,
becoming light and terrain driven overnight.

&&

.TWC WATCHES/WARNINGS/ADVISORIES...None.
