Synopsis Some showers and thunderstorms this evening with a
clearing trend from the west. Isolated to scattered thunderstorms
are then expected Thursday into early next week, with the
greatest thunderstorm coverage mainly east to south of tucson.

Discussion A nice convergent area through southeast arizona
this afternoon along with dynamics from the trough immediately
west of the area led to organized thunderstorm development.

Multiple strong outflows with blowing dust as well as propagation
along the outflows, and intersecting boundaries. Just cleaning up
this evening with showers embedded in debris cloud and a clearing
trend from the west.

Our favorable thunderstorm environment will shift a little
eastward tomorrow as the low upstream sags into southern
california and some drying wraps into the southwest part of the
state. After some minor adjustments for latest trends, the current
forecast looks solid for less activity tomorrow.

Aviation Valid thru 25 06z.

Isolated -tsra -shra into early Thursday morning, then scattered
tsra east of ktus Thu afternoon. Brief MVFR conditions with some
storms. Strong gusty outflows with some storms, otherwise,
surface wind less than 12 kts. Aviation discussion not updated for
taf amendments.

Fire weather An easterly flow will develop by Friday keeping
enough moisture around southeast arizona for daily rounds of
thunderstorms into next week. Coverage will vary from day to day
but areas east of tucson will be most favored overall. 20 foot
winds will remain light except in the vicinity of thunderstorms.

Prev discussion Models indicate mid level ridging high
pressure starts to shift into northern az as early as Thursday
with resultant north to northeast mid level flow over SE az. While
storm coverage will not be as widespread as today, enough
moisture and instability will remain in place for isolated to
scattered storms, especially east of tucson.

As the high becomes anchored to our north, easterly flow will
keep enough moisture in place for daily rounds of isolated to
scattered storms into early next week. While eastern locales will
be most favored, any disturbance moving from east to west in the
flow could help storms to progress into the western deserts on a
given day. Timing of such an occurrence is difficult to pinpoint
however.

High temperatures will generally remain above seasonal averages,
but fluctuate depending on thunderstorm timing.

Twc watches warnings advisories None.

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.
