Synopsis Very warm mid-january afternoon temperatures and dry
conditions will persist through Friday. A storm system will then
move across the area this weekend, resulting in much cooler
temperatures, gusty winds and a chance of valley rain and mountain
snow. High pressure aloft will build back across the area next week
for a return to dry and warmer conditions.
Discussion A ridge of high pressure aloft will shift over the
region tonight through Friday. This will result in a warmup with
high temperatures peaking Friday in advance of a significant change
in the weather this weekend. That said, please refer to the previous
discussion in this product for more details on the big weather
change slated for this weekend.
Aviation Valid thru 19 06z.
Skc-few clouds above 20k ft agl late tonight into Thursday evening.
Surface wind variable in direction mainly less than 12 kts. However,
ktus vicinity surface wind ely sely with occasional gusts near 18

Fire weather Dry conditions through Friday. There is a chance of
valley rain and mountain snow late Friday night into Saturday. A few
lingering showers near new mexico state line Saturday night, then
dry conditions Sunday into next Wednesday. Occasionally gusty winds
should accompany showers Saturday with gusty northwest winds upper
gila valley including safford on Sunday. Expect terrain driven winds
mainly less than 15 mph at other times.
Prev discussion The shortwave ridge to our west will shift east
across the region through Friday, with the result being a warmup in
temperatures across southeast arizona. By Friday, daytime|
temperatures across southeast arizona will be 7-14 degrees warmer
compared to the highs today, with afternoon readings topping out 8-
12 degrees above seasonal averages.
This warming trend will be short-lived as a storm system moves into
the great basin Friday and then across northern arizona Saturday and
Saturday night. This system will push a strong cold front across the
state from west to east Friday night and Saturday. Expect a chance
of precipitation along this frontal boundary, as well as strong and
gusty winds and sharply colder temperatures behind the front. The
latest GFS model solution has the front moving through the tucson
metro between 15z-18z Saturday and east of the arizona new mexico
state line around 00z Sunday. While the track of the upper low has
been very consistent between the GFS and ECMWF solutions, the ecmwf
frontal boundary passage is about 6 hours slower versus the gfs.
Only light precipitation amounts are expected across southeast
arizona with this system, with most valley locations receiving one-
tenth of an inch or less of rainfall. Snowfall totals in the
mountains will be around 1 inch in the mountains surrounding tucson
(catalina, rincon and santa rita mountains), 1-2 inches in the
chiricahua mountains and 1-3 inches in the white mountains. The
biggest impact with this system will be the colder temperatures
Saturday and Sunday (about 15 to 20 degrees colder than Friday),
with a freeze possible across the tucson metro area both Sunday and
Behind the system, high pressure aloft will build back in across the
desert southwest. Daytime temperatures will warm to a couple of
degrees above normal on Monday and then 7-10 degrees above normal by
the middle of next week.
Twc watches warnings advisories None.

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.
