Synopsis Hot, near or above record high temperatures will be
around once again on Wednesday with dry conditions through early
Wednesday. Increasing moisture late Wednesday onward will bring
scattered thunderstorms to the area with cooler, near normal
temperatures this weekend.

Discussion Very hot for august with record to near record high
temperatures around today and once again tomorrow. Excessive heat
warning is in effect until 8 pm Wednesday for the lower
elevations of pima, pinal and graham counties. Moisture limited
across the area today with values mostly less than 1". The
exception is right along the az nm border where values are
slightly above 1". So a few storms possible along the az nm border
and also along the intl border east of nogales.

For tonight, will see low level moisture values increase
associated with outflows coming out of new and old mexico. The
outflow out of new mexico may generate a few showers storms across
cochise county later tonight that may persist into Wednesday
morning, per uofa wrfnam.

Wednesday: pwat values increasing into the 1" to 1.30" range with
highest values south of tucson. This will result in an increase
in thunderstorms, in the isolated to scattered range mainly south
and east of tucson.

Thursday: pwats will be ranging from 1" east to over 1.5" west
with best chances for storms being west and south of tucson.

Localized heavy rainers with light and variable steering flow.

Friday: the steering flow becomes more easterly across the area
and combined with pwat values similar to Thursday and a weak
inverted trof passing through sonora looking at the most active
convective day in almost two weeks with the potential for activity
to continue into the overnight hours.

Saturday: upper level ridge axis north of the area will put the
area under NE flow aloft which will bring an increasing chance
for a rim shot event.

Sunday: lingering moisture around for the chance of afternoon and
evening storms.

Monday and Tuesday: conditions start to dry out with lowering pwat
values as upper high center settles over the area.

Temperatures will be cooling later in the week and continuing
into the weekend where highs could be at or a few degrees below
normal. That will be short lived as highs warm back above normal
early next week with the potential for near record highs once
again next Tuesday.

Aviation Valid through 22 00z.

Few-sct clouds at 12k-16k ft msl thru the forecast period. There is
a slight chance of -tsra -shra near the az nm border including near
kdug and across the white mountains into late this evening. Isold-
sct -tsra -shra redevelop Wednesday afternoon from ktus kols
eastward. Sfc wind generally nwly into this evening at less than 12
kts with a few gusts to 15-20 kts. Terrain driven winds less than 10
kts persist overnight with SW to NW winds Wednesday afternoon mainly
less than 12 kts. Aviation discussion not updated for TAF amendments.

Fire weather Limited moisture today will result in any
shower thunderstorm development confined to areas along the az nm
border including the white mountains. Better coverage of showers and
thunderstorms begin tomorrow mainly east of tucson and spread
westward and northward into Saturday. Near record high temperatures
are expected through Wednesday, but the return of deeper monsoonal
moisture will allow temperatures to fall back to near seasonal
levels by Friday. Any thunderstorms that do develop may produce
gusty and erratic outflow winds. Otherwise, 20-ft winds will
generally follow normal diurnal trends at less than 15 mph.

Climate Another day of record to near record highs tomorrow
across southeast arizona. Below are the forecast highs for
Wednesday versus the daily record highs for selection locations
across southeast arizona.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
