Synopsis Scattered to numerous afternoon and evening
thunderstorms will prevail into early next week. The greatest
daily thunderstorm coverage should occur east to south of tucson
with reduced thunderstorm activity across the western deserts.
Discussion Mostly sunny to partly cloudy conditions prevailed
across southeast arizona this morning with a few storms already
starting to pop up, mainly over the higher terrain east of tucson.
Upper air charts showed inverted trof extending from northwest nm to
southern sonora mx. Visible imagery this morning showed a MCV near
glenwood nm which was drifting slowly to the southwest. Tucson
morning sounding was fairly similar to yesterday with a pw values of
1.82" and a bit stronger northerly steering flow. Latest model data
thou is indicating that the steering flow across graham, greenlee
and cochise counties this afternoon will be rather light which will
increase the flash flood threat due to slow moving storms. WFO el
paso has already hoisted a flash flood watch for SW nm for this
afternoon and evening and I will continue to contemplate one for
portions of my eastern zones. The cell that developed over the
chiricahua mountains after 830 am dumped 0.80" in less than an hour.
The last three runs of the NAM has been all over the place with
respects to placement of heavy rain this afternoon, tonight and into
the overnight hours.
Flow aloft becomes more e-se tonight late tonight and potentially
southerly on Sunday as models move inverted trof across the area.
Sunday could end being rather gunked over with lots of showers
around and embedded isolated thunderstorms.
Below normal high temperatures to continue this weekend with well
below normal highs possible on Sunday based on lots of cloud cover
around. Mid-shift already made downward adjustments for today and
Sunday and await full 12z MOS data before making any further
changes. At this time, the forecast high in tucson for Sunday of 89
degrees would be the first sub-90 high in july since 2010.
Monsoon train remains on the track next week while high temperatures
warm back to late july normal values.
Aviation Valid thru 23 12z.
Vfr conditions with cloud decks generally 5k-10k ft agl with bkn
layers above, and surface wind variable in direction mainly less
than 12 kts. Sct tsra shra developing after 22 18z and continuing
through the remainder of the period. Winds vicinity tsra could gust
40+ kts. Aviation discussion not updated for TAF amendments.
Fire weather Scattered to numerous mainly afternoon and evening
thunderstorms will continue into early next week with locally heavy
rain and strong winds. Temperatures will remain below normal with a
continuation of elevated humidity levels through Tuesday. Wednesday
through Friday conditions will become a bit drier and warmer with
somewhat less convection. From 20-foot winds will mainly remain
below 15 mph with the exception of strong outflow winds in the
vicinity of thunderstorms.
Twc watches warnings advisories None.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
