Synopsis Drier air and building high pressure will result in less
thunderstorm activity with higher afternoon temperatures again
Monday. As the high center returns to east of our area, deep
moisture will return this week with a good chance of showers and
thunderstorms by Tuesday or Wednesday.

Discussion While conditions were not favorable for
widespread thunderstorm activity today, the isolated cells that did
develop packed a good punch. Several severe warned storms initiated
along the international border with one report of 1" hail from a
spotter west of douglas. The storm of the day occurred just
north northeast of nogales, likely producing large hail and a nearby
gauge measured 1.65" of rainfall in a short period. Conditions have
since improved, with the radar switching over to clear air mode.

Precipitation should be done for the night and the forecast appears
in good shape. See the previous discussion for further details.

Aviation Valid through 21 06z.

Few-sct cloud bases around 8-12k ft agl continue through the period.

Isolated tsra shra develop Monday afternoon, again favoring areas
south to east of tucson. Light and variable surface winds settle wly-
nwly during the afternoon, but still remain less than 12 kts outside
of thunderstorm induced gusts. Aviation discussion not updated for
taf amendments.

Fire weather The pattern gradually shifts to start the work week
allowing for better coverage of showers and storms, especially by
midweek. Terrain driven 20-ft winds persist at less than 15 mph,
except for in and around thunderstorms where strong outflows may
occur.

Prev discussion Warmer temperatures aloft will continue to hinder
the development of thunderstorms today and again tomorrow as high
pressure shifts over arizona. Both the GFS and ECMWF showed the high
pressure ridge becoming centered over the southern plains by
Wednesday. This more favorable position of the high will advect
deeper moisture pooled south of the region back into the area as
early as Tuesday. Thereafter, the return of daily showers and
thunderstorms can be expected. Cooler high temperatures will also
coincide with the moisture increase and subsequent upswing in
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.
