Synopsis Valley rain and mountain snow showers associated with
slow moving low pressure south of arizona will gradually dissipate
overnight as the low moves east. Wraparound moisture will allow
for some lingering mountain snow showers east of tucson on Monday,
but drier air will move into the area through mid week. A trough
will sweep through the four corners late in the week bringing
increased cloud cover and cooler temperatures, but at this time it
doesn't look to bring much in the way of precipitation. Cooler
temperatures will linger through next weekend.

Discussion Water vapor imagery this evening showed the upper
low which bought valley rain and mountain snow to the area today
was located over far NW sonora mexico or south of central pima
county. Areal coverage of showers has decreased over the last
several hours with the exception along the international border,
or across santa cruz and southern cochise counties. As the upper
low continues to slowly move east tonight, the last good slug of
moisture over eastern sonora mexico will move into cochise county
with the chiricahua mountains seeing accumulating snows into early
Monday morning. Thus have extended the winter weather advisory
for the chiricahua mountains until 2 am. The winter weather advisory
for the rest of the mountain ranges was cancelled although will
still see isolated showers and mountain snow showers continue
through the overnight hours into Monday morning.

Aviation Valid thru 19 00z.

An upper level low pressure system over northwest sonora mexico
will continue to move east across the area thru the valid period.

Expect isolated to scattered valley rain and mountain snow
showers to continue into Monday. MVFR CIGS vsbys will
occasionally accompany the shra especially near terrain and east
of tucson. Winds mainly southeasterly at around 8 to 12 kts.

Aviation discussion not updated for TAF amendments.

Fire weather Low pressure will bring much higher relative
humidity and scattered precipitation to the area through Monday.

East to southeast winds this afternoon will give way to relatively
light diurnally driven winds during through midweek. Once the
current weather system moves to the east, expect dry weather the
remainder of the week. As a weather system approaches Thursday,
expect some increased breezes. The bulk of this system will pass to
our north, thus dry and cool weather to end the work week and into
next weekend.

Twc watches warnings advisories
Winter weather advisory until 2 am mst Monday for azz512.

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.
