Synopsis Dry conditions will prevail across much of the
area through Tuesday with a few record low temperatures for the
coldest valley locations southeast of tucson. Expect scattered
showers and thunderstorms Wednesday, then isolated to scattered
showers and thunderstorms mainly east of tucson Thursday into
Discussion Clear skies prevail across much of southeast arizona
early this morning except for scattered to broken lower level clouds
southeast of tucson. The bulk of these clouds should shift eastward
into new mexico later today allowing for clear skies across much of
the area. Expect clear skies or just a few clouds at times
especially east of tucson tonight into Monday night.
The 24 00z gfs ECMWF cmc were fairly consistent versus their
respective previous solutions regarding the development of a closed
upper low within the base of the longwave trough Tuesday night into
Wednesday. These solutions progged the upper low to become
positioned over west central arizona (ecmwf) or southwest arizona
(gfs) by midday Wednesday. These positions were slightly further
east of the progged upper low positions via the 23 00z gfs ECMWF cmc
solutions. The model pops and measurable liquid rain amounts were
subsequently somewhat further east as well versus model solutions of
24 hours ago.
Thus, forecast confidence at this time is fairly high that scattered
coverage of showers tstms will occur east of tucson Wednesday
afternoon and evening. Forecast confidence is considerably lower for
measurable rainfall of significance to occur within much of the
tucson metro area, and especially for locales west of tucson.
At any rate, this issuance of the official forecast depicts
scattered showers tstms east of tucson Wednesday afternoon evening,
and isolated showers tstms from tucson westward into central pima
county and south central pinal county. Dry conditions should occur
Wednesday across western pima county. The upper low is progged to
lift northeastward into northeast arizona southeast utah by midday
Thursday. Isolated to scattered coverage of showers tstms should
occur east of tucson Thursday into Friday night.|
Deeper moisture may be shunted somewhat further westward Saturday as
a shortwave trough moves across the area. The 24 00z gfs ECMWF were
supportive of this notion, but a quick glance at the 24 006z gfs
kept deeper moisture further east due to a less amplified shortwave
trough. At any rate, have maintained a slight chance of
showers tstms from tucson eastward Saturday with dry conditions
across western locales.
Expect near record low temperatures tonight and Monday night across
portions of cochise county, including tombstone and douglas.
Otherwise, daytime temperatures that will be below seasonal normals
through Monday, then high temperatures will trend closer to seasonal
normals Tuesday into next Saturday.
Aviation Valid thru 25 12z.
A few to broken clouds at 5k-8kt ft agl southeast of ktus mainly
this morning, otherwise clear skies. Surface wind wly nwly 10-15 kts
with gusts to 20 kts this afternoon. Surface wind variable in
direction less than 12 kts at other times. Aviation discussion not
updated for TAF amendments.
Fire weather Dry conditions will prevail across much of the area
through Tuesday. Scattered showers and thunderstorms will occur
Wednesday, then isolated to scattered showers and thunderstorms
especially east of tucson Thursday into next Saturday. 20-foot winds
will mainly be terrain driven less than 15 mph through Wednesday,
then gusty east winds at times Thursday into Friday.
Climate The current low temperature forecast at tucson
international airport for Monday morning is 54 degrees. That would
be the coolest low temperature in september since 2004 when 54
degrees occurred on the 22nd. The last time tucson recorded a low of
53 degrees (which may occur Monday morning) in september was in 1988
on the 23rd.

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.
