Synopsis Expect limited thunderstorm activity through Tuesday as
high pressure builds overhead. The drier pattern will also bring
hotter temperatures, especially by Tuesday. A more favorable flow
with adequate moisture will provide scattered mainly afternoon and
evening thunderstorms Wednesday into next weekend.
Discussion High pressure continues to build in from the
northwest accompanied by mid level warming. Another 1.5c warmer at
500mb on the morning sounding. Plenty of moisture in place with
precipitable water values ranging from 1.3 inches east to 1.7
inches west and surface dew points easily hanging on to 60+ values
this afternoon. Most of that will be wasted with the weak
dynamics. A little better environment still exists for storms
south and southwest of tucson. It was a tad slow, but we're seeing
a couple of mountain storms pop up now in the huachucas and
chiricahuas. We may see a couple wandering into lower elevations
later; propagating along outflows.
The ridge will strengthen overhead, with the mid level high center
consolidating over arizona and new mexico over the next 48 hours.
Some modest mid level drying as this occurs, but surface dew
points will remain about average for late august. Temperatures
will climb back to around 6 to 8 degrees above average, but are
expected to fall 3 or 4 degrees short of our recent record heat.
At this point it looks like just below excessive heat levels with
a 106 expected for tucson Tuesday afternoon. Meanwhile, conditions
will remain less than favorable for thunderstorms again Monday.
The extra heat on Tuesday will probably bully some storms up later
in the afternoon than usual, but they will still favor mountains
with limited valley support outside of strong outflows. By
Wednesday most ensembles and ensemble means are weakening high
pressure over the area with deeper moisture over the SE corner of
the state. Some associated mid level cooling and upper level
diffluence on the eastern flank of the high should lead to a busy|
thunderstorm period for our area Wednesday and Thursday. Both
deterministic GFS and ECMWF are showing some flavor of inverted
trough rotating around the eastern periphery of the high Friday
afternoon, with some enhanced thunderstorm chances for our corner
of the state. This is supported by naefs ensemble mid level
By next weekend, ensembles suggest the ridge shifting to near the
4-corners region as a trough digs into the pacific northwest and
another into the great lakes and midwest. That would tend to keep
things going with a favorable flow and a potentially active
tropics to keep an eye on to start september.
Aviation Valid through 27 00z.
Isolated -tsra -shra thru 26 04z primarily along the international
border from kdug westward to south of sells, including kols and
kalk. Otherwise, cloud decks mainly at 10k-15k ft msl. Sfc wind
generally less than 12 kts, except in the vicinity of ksad where
wind speeds will be 12-18 kts with gusts to around 25 kts. Sfc wind
direction will favor a wly nwly direction thru 26 03z and then again
aft 26 18z, with wind direction variable in direction between 26 03z
and 26 18z. Aviation discussion not updated for TAF amendments.
Fire weather Isolated thunderstorms are expected through the
evening hours tonight mainly south to southwest of tucson. Dry
conditions will then occur across much of the area Monday and
Tuesday, with just a slight chance of thunderstorms in the mountains
of santa cruz and cochise counties Tuesday afternoon. A favorable
flow pattern for shower storm development returns Wednesday and
continues through next weekend, resulting in isolated to scattered
mainly afternoon and evening showers and thunderstorms. Aside from
any thunderstorm wind gusts, 20-foot winds will be terrain driven
and mainly under 15 mph.

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.
