Synopsis High pressure and a little less moisture over the
area will limit thunderstorm development trough Saturday with
temperatures remaining a couple of degrees warmer than normal. More
favorable upper level flow should provide for an increase in
thunderstorm coverage starting Sunday and continuing into next
week.

Discussion Latest IR satellite imagery shows mostly cloudy skies
across the vast majority of southeast arizona with a decaying mcs
across northern sonora. A few sprinkles or light showers are showing
up on kemx radar imagery mainly west of tucson but these should
diminish through the early morning hours. The mid upper level flow
pattern features a high pressure extending from texas into new
mexico with another weak high near the baja spur. Latest
deterministic and convective allowing models are in relatively good
agreement keeping isolated to scattered showers and thunderstorms
this afternoon into evening along the international border,
especially from santa cruz to western cochise county and along the
higher terrain. Given h5 temperatures progged at -5c to
-6c today with modest moisture (pwat values averaging around 1.25"),
instability to support thunderstorms will be limited across most of
the region. Steering flow is also rather light around 5 to 10 kts so
the storms that do form will tend to favor the terrain and nearby
valleys.

A similar setup is expected on Saturday, though the mid upper level
high is progged to strengthen slightly across the region with the
best moisture once again along the international border. This will
result in a low grade monsoon pattern with a few storms primarily
along the higher terrain and international border mainly from santa
cruz county eastward.

The pattern change that many folks who haven't seen rain are hoping
for will begin to establish itself on Sunday as the mid upper level
high shifts to the four corners region. While this occurs, a more
favorable easterly flow pattern will establish itself with deeper
moisture. This points to a more active period for all of southeast
arizona including the lower deserts starting as early as Sunday and
continuing through the early to middle portions of next week.

Aviation Valid through 20 12z.

Isolated -shra west of ktus ending around 12z-14z this morning.

Isolated -tsra -shra this afternoon and evening southeast to
southwest of ktus (and especially near kols kfhu), and across the
white mountains northeast of ksad. Expect brief wind gusts to 40 kts
near stronger tsra. Otherwise, cloud decks mainly 12k-18k ft msl.

Surface wind this afternoon nwly 10-20 kts with gusts near 25 kts.

The strongest speeds will be near ksad. Surface wind variable in
direction mainly under 12 kts at other times. Aviation discussion
not updated for TAF amendments.

Fire weather Isolated afternoon and evening thunderstorms through
Saturday mainly southeast to southwest of tucson, and across the
white mountains northeast of safford. Expect scattered thunderstorms
area-wide Sunday through Tuesday. Somewhat less thunderstorm
coverage should translate into isolated to scattered mainly
afternoon and evening thunderstorms next Wednesday into Thursday.

Expect brief strong and erratic winds near thunderstorms. Aside from
thunderstorm wind gusts, 20-foot winds across the upper gila river
valley through Sunday will approach 25 mph from the northwest during
afternoon hours. 20-foot winds will be mainly under 15 mph elsewhere.

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.
