Synopsis High pressure overhead will shift east of our area
later today and Tuesday. As this happens, deeper moisture will
push up from the south and thunderstorms will increase while
temperatures fall back to near or below average. Storms increase
this afternoon, then Tuesday and Wednesday should be busier with
strong storms and locally heavy rainfall.

Discussion Expect a weak flow today as high pressure over
arizona shifts into new mexico. At that point our southerly to
southeasterly flow will be back in control, and we will reengage
with a long fetch of deep moisture. Add in a little mid level
cooling and the monsoon will be back in business across all of se
az by Tuesday and Wednesday.

Currently our precipitable water values range from 1.4 inches
south and west of tucson, to about 1 inch near the new mexico
border. That will push above 1.55 inches for tucson westward by
tomorrow, with values closer to 1.25 inches in far eastern areas.

Storm environment winds and a solid increase in convective
potential will favor thunderstorm development, but actual storm
motion will be on the slower side. It's shaping up for strong wet
microburst potential Tuesday afternoon. Slow developing Wednesday
behind some lingering debris cloud, then another period of strong
wet microburst potential late afternoon and early evening with
outflows keeping storm activity going overnight Wednesday.

After that our southerly flow will continue as high pressure
remains east of our area. Plenty of moisture to continue daily
thunderstorm chances through the weekend. Keep an eye out for
embedded impulses in the moist southerly flow.

Aviation Valid through 21 12z.

Sct-bkn clouds above 15k ft agl with some clearing through mid
morning. Few-sct clouds redeveloping this afternoon with bases
around 8-12k ft agl along with isolated tsra shra, favoring areas
south and east of ktus. Sfc winds variable at less than 10 kts this
morning, increasing out of the W to NW this afternoon, but generally
remaining less than 12 kts outside of thunderstorm induced gusts.

Light and variable winds then occur tonight into Tuesday morning.

Aviation discussion not updated for TAF amendments.

Fire weather The pattern will be better suited for
shower and thunderstorm development early this week. Areal coverage
of showers and storms, some with heavy rainfall, will occur by
Wednesday and continue into this weekend as moisture levels
increase. Terrain driven 20-ft winds persist at less than 15 mph,
except for in and around thunderstorms where strong outflows may
occur.

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.
