Synopsis A more active monsoon pattern will continue through
Saturday with daytime high temperatures near or slightly below
normal. A drying trend then resumes Sunday with isolated storms
limited to near the international border as high pressure starts to
build overhead. Dry conditions generally prevail Monday and Tuesday
with above normal temperatures returning. Thereafter, moisture
returns by Wednesday, resulting in a chance of showers and
thunderstorms the latter half of next week.

Discussion The latest GOES satellite imagery shows partly
cloudy skies east of tucson, with mostly sunny skies to the west of
tucson. Kemx area radars are rather quiet across southeast arizona
early this afternoon, with showers thunderstorms noted in the white
mountains and over mt. Graham and the huachuca chiricahua mountains
attm. Blended total precip water imagery has shown little change
from this morning with pwat's ranging between 1.0" and 1.3" across
most of the forecast area (except in the white mountains with values
around 0.7"). Surface dewpoints have fallen into the 50's across the
southern half of the state.

With plenty of moisture in place and abundant sunshine expect
convection to continue to initiate over the mountains south and east
of tucson through the remainder of the afternoon hours, gradually
pushing out into the valleys by the mid to late afternoon hours. The
latest high res models continue to show areas south of tucson
becoming more active by the mid late afternoon hours. Steering flow
is rather weak, with the general movement of storms to the
east northeast. Will have to rely on outflow boundaries to get
storms into the lower deserts northern portion of the cwa. Overall,
the peak timing for maximum storm coverage today will be between 4
pm and 9 pm, with the main threats being heavy rainfall and strong
winds small hail with the stronger storms. If storm outflows do
manage to work into northern pima southern pinal counties, blowing
dust could also be a concern, especially along the i-10 corridor.

The overall pattern remains conducive for storm development on
Saturday as deep moisture continues to stream northward from mexico.

Expect isolated to scattered mainly afternoon and evening showers
and thunderstorms south southeast of tucson.

A drying trend then begins on Sunday as strong high pressure aloft
off the california coast shifts inland and becomes elongated from
california through arizona and into new mexico. Expect only isolated
shower thunderstorm development on Sunday along the international
border. Mainly dry conditions are expected Monday and Tuesday as the
upper high strengthens overhead, with high temperatures these days
climbing back 3-7 degrees above normal.

By Wednesday of next week, the upper highs shifts east of the area
which allows moisture to begin to work back into arizona from the
east southeast. Increasing shower thunderstorm chances are noted
from Wednesday onward into next weekend as this moisture transport
continues. Numerical guidance values indicate high temperatures
lowering from a couple of degrees above normal next Wednesday to a
couple of degrees below normal by Friday of next week.

Aviation... Valid through 25 00z.

Isolated tsra shra currently developing east to south of ktus,
becoming scattered to numerous across much of southeast arizona
later this afternoon into this evening. Expect decreasing coverage
of tsra shra tonight with the bulk of activity ending by daybreak on
Saturday, redeveloping Saturday afternoon. Brief wind gusts to 40
kts and MVFR CIGS vsbys with the stronger tsra. Otherwise, cloud
decks mainly 12k-18k ft msl. Surface wind this afternoon wly nwly 8-
15 kts with gusts near 20 kts, decreasing light and variable
overnight. Aviation discussion not updated for TAF amendments.

Fire weather Scattered to numerous thunderstorms across much of
southeast arizona this afternoon and evening, followed by another
round of storms Saturday with slightly less spatial coverage. Drier
air starts to work its way in on Sunday bringing only isolated
thunderstorms, further drying on Monday into Tuesday. However, this
downturn is short-lived as moisture increases by the middle of next
week returning scattered storms to the region. Other than breezy
afternoons in the upper gila river valley this weekend, 20-foot
winds will be terrain driven mainly under 15 mph. The usual threat
from strong thunderstorm outflow winds also remains in place.

Twc watches warnings advisories None.

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.
