Area Forecast Discussion
National Weather Service Tucson AZ
300 PM MST Fri Aug 3 2018

.SYNOPSIS...Daily rounds of isolated to scattered thunderstorms
can be expected into next week. Some storms will generate heavy rain
and strong winds. Temperatures will remain several degrees above
average for early August.

&&

.DISCUSSION...Upper level ridge axis today extended from off the
southern California coast east into west Texas. Further northeast
there is an upper level trof moving through Colorado/nrn New
Mexico. Overall this has put southern Arizona under light W-NW flow
aloft. Thunderstorm activity this afternoon has been limited to
areas east and south of Tucson and mainly favoring the mountains.
Locally strong wind gusts and heavy rain possible with these
storms.

Both GFS/NAM have a thunderstorm complex later this evening over
northeast Sonora which could send outflows north into Cochise
county where elevated thunderstorms are possible during the
overnight hours.

Mid-level flow turns to the east on Saturday. The combination of
warm mid-level temperatures around -3C to -4C along with below
normal PW values for early August will result in only isolated
thunderstorms along the International border and up in the White
Mountains. Similar story on Sunday. Highs over the weekend will
run 4 to 6 degrees above normal.

Next will see an increase in thunderstorm activity under easterly
flow aloft. Picking a day which will be the first up day is a
little tricky right now. At this time looks like Tuesday will be
that day. Will keep an eye on the tropics as models move a
hurricane well west of the southern tip of Baja. May be close
enough to enhance moisture across northern Mexico. Stay tuned.

High temperatures early next week remaining 3 to 5 degrees above
normal then cool closer to normal to end the week under added
moisture and cloud cover.

&&

.AVIATION...Valid through 05/00Z.
Scattered -TSRA/-SHRA mainly east to south of KTUS into this evening,
decreasing in coverage after sunset. Cloud bases are generally
10k-15k ft AGL. Surface winds remain less than 12 kts following
typical diurnal flow, with the possibility for possible
thunderstorm induced gust to 40 kts. Aviation discussion not
updated for TAF amendments.

&&

.FIRE WEATHER...Scattered thunderstorms will favor locations mainly
east to south of Tucson into this weekend. Isolated to scattered
thunderstorms then prevail areawide Monday into next Friday. 20-foot
winds remain terrain driven at less than 15 mph, with slightly
gustier afternoon conditions across the Upper Gila River Valley over
the weekend. Daytime temperatures hit a few to several degrees above
normal through a majority of the forecast.

&&

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