Synopsis Dry conditions with unseasonably warm daytime
temperatures through midweek. Increased moisture will then bring
isolated to scattered showers and thunderstorms mainly east of
tucson Friday into Saturday. Dry conditions to return Sunday, with
next week shaping up to be a little cooler and windy at times.
Discussion Just looking at some high clouds across the area today
with warm afternoon temperatures. The focus will shift to the
possibility of thunderstorms Friday and Saturday, followed by a dry
weather system entering the region early next week. The current
forecast looked on track, so no updates necessary this morning.
Please refer to the additional sections for more details on the
upcoming weather changes.
Aviation Valid through 26 18z.
Scattered to overcast clouds above 13k ft agl becoming few to
scattered cirrus clouds this afternoon and continuing into early
Thursday morning. Surface wind this afternoon and early evening west
to northwest 8-15 kts with occasional gusts near 20 kts. Surface
wind variable in direction mainly under 10 kts at other times.
Aviation discussion not updated for TAF amendments.
Fire weather Light winds and dry conditions into early
Thursday, then increased moisture from the east brings a slight
chance of thunderstorms over the white mountains Thursday afternoon
and evening. Sufficient moisture for isolated to scattered mainly
afternoon and evening thunderstorms from tucson eastward Friday into
The main concern Friday into Saturday is thunderstorms capable of
starting fires and producing strong outflow winds, especially in the
higher terrain where development is more likely. Dry conditions will|
then prevail Sunday into Tuesday.
20-foot winds terrain driven less than 15 mph through Thursday.
Gusty east to southeast winds from tucson eastward Friday morning
should occur before potentially gusty thunderstorm outflows Friday
afternoon into Saturday. Gusty south to southwest winds are on tap
Saturday into Monday. Critical fire conditions may return Monday
particularly across mountains from tucson southward and
southeastward into santa cruz cochise counties.
Prev discussion Another week low off the eastern pacific is
bringing a few clouds to the area today. Only virga on this side of
the border with the light shower activity remaining in northern
mexico. Otherwise strong high pressure will bring another day of
temperatures around 10 degrees above average, with these warm
temperatures continuing into the weekend.
The main story continues to be the convection Friday and Saturday.
Moisture spreading in from the east and southeast the second half of
the week will combine with strong solar insolation and weak mid
level cooling in the wake of the ridge axis shifting to our east.
Confidence is increasing as more GEFS plume members lean toward
operational ECMWF resolutions. Also, more and more NCEP sref plume
members are showing the increased moisture and mu ml CAPE Friday
afternoon into Saturday afternoon. High based storms with dry
microburst potential still a concern.
With the newly consolidated flow, we will be ripe for a pattern
change early next week with a potential mean trough position being
established through western states. This will shunt our moisture
eastward as early as Sunday. It will also trend us toward cooler
temperatures and gusty winds by Monday.
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.
