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
storms mainly east of tucson into Saturday. A gradual warming
trend will push temperatures back up to near and then above
average over the next several days.
Discussion Plenty of sunshine in a dry westerly flow under the
trough. The 12z ktwc sounding showed 1 3 of an inch precipitable
water and surface dew points are in the teens and 20s. We may see
a few patches of thin cirrus overnight or tomorrow morning, but
generally clear skies otherwise. Temperatures will start to slowly
recover to normal levels over the next 72 hours as the strongest
portion of the trough lifts well northeast of our area. Our
current forecast looks good, with no updates this morning. Please
see the previous discussion below for additional details.
Aviation Valid thru 26 18z.
Skc to just a few cirrus clouds at times. Normal diurnal wind
trends generally less than 12 kts. Aviation discussion not
updated for TAF amendments.
Fire weather A dry atmosphere will dominate the region through
Tuesday morning. A slight chance of isolated storms will exist
starting Tuesday evening into the overnight hours east of tucson.
Then isolated to scattered thunderstorms Wednesday through Friday
mainly for areas east of tucson. Some lingering moisture will
allow for a slight chance of storms Saturday. 20-foot winds will
be terrain driven less than 15 mph through Wednesday. Thursday and
Friday winds will shift to easterly with afternoon gusts between
Climate The low temperature of 54 at tucson international
airport this morning is the coolest low temperature in september
since 2004 when 54 degrees occurred on the 22nd. In addition,
douglas set a record low this morning with 41 degrees.
Prev discussion On Tuesday, an upper level low will develop
over NW az and gradually move south in response to an upper level
ridge amplifying off the west coast into the pacific nw. While
that is happening, moisture from TS pilar will start to push north
into chihuahua mx while easterly flow pushes moisture west across
new mexico. This moisture will continue to push west into our
eastern areas Tuesday night into Wednesday, bringing scattered
showers and isolated thunderstorms to mainly graham, greenlee and
cochise counties. Still some uncertainty in the models on how far
west the moisture will get into pinal, pima and santa cruz
counties. At this time, the best areas for good rainfall totals
from this upcoming system will be across graham and greenlee
counties with QPF total mostly in the 0.50" to 1" range in the
mountains will less than 0.50" in the valleys. Highs Tuesday near
normal then slightly cooler on Wednesday. There is a larger
ensemble spread in high temperatures across graham and greenlee
counties on Wednesday, so I could easily the high temperatures
ending up cooler than forecast. Something that later shift will
get a handle on.
Although the upper low lifts out of the state later on Thursday and
some drier air pushes in from the west, there will still be enough
residual moisture around eastern the areas for slight chance of
storms into Saturday.
High temperatures warming back above normal to close out
september and start october.

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.
