Synopsis Patchy fog is possible again tonight but should not be
as widespread as Friday night. A couple of weather systems will
bring a chance of showers Sunday into Tuesday. As colder air moves
into southeast arizona Monday, snow will fall in the mountains,
especially the whites. After the precipitation exits the region,
freezing temperatures will return to valley locations Tuesday
night, mainly east of tucson.

Discussion While the fog has lifted across the area, low level
moisture and some low-based cloudiness remain. Dew points are
still in the 40s to around 50. Expect patchy fog to form again
later tonight, although it should not be as widespread.

Looking at the big picture, an upper low west of baja california
continues to direct moisture into southeast arizona. The low will
kick eastward Sunday, and combined with a jet streak, act on the
moisture to develop isolated to scattered showers, mainly east of
tucson. Snow levels will remain high with only the very highest
peaks cold enough for any snow through Sunday night.

Another area of low pressure over the pacific northwest will dive
southeastward toward arizona Monday before turning east Tuesday.

The associated cold front will lower snow levels Monday night and
provide enough lift for significant mountain snow. At this time,
the rim figures to be the most favored area for accumulating snow,
but snow may also accumulate Monday night on other mountain
ranges in southeast arizona.

As the cold front passes Monday, expect breezy to windy
conditions. Then after skies clear Tuesday night, temperatures
will drop below freezing for the first time in over a week in
valleys east of tucson and may even approach freezing in the
tucson metro.

Arizona will remain under the influence of low pressure aloft
during the latter half of the new work week, but at this time no
significant precipitation is expected. High temperatures for the
next 7 days will remain at or below seasonal normals. Tuesday and
Wednesday will be the coldest days, with highs 5 to 10 degrees
below average.

Aviation Valid thru 19 00z.

For the remainder of the afternoon and night expect sct clouds 3-6
kft agl and bkn high clouds. Due to lingering low-level moisture
patchy fog will again be possible between 18 09z - 18 16z, which
could create MVFR visibilities during that time period. CIGS will
also drop starting Sunday morning to bkn 3-6 kft agl with sct clouds
at 25 kft agl. Winds will be variable less than 10 kts through
18 18z then increase out of the southwest at 10-15 kts with gusts
between 20-25 kts. Aviation discussion not updated for taf
amendments.

Fire weather After several days of very wet conditions across
southeast arizona, today will be generally dry with light winds.

There will be another chance of showers Sunday into Tuesday
morning as a couple of weather systems track through the
southwest. Best chances will be along the new mexico arizona
border and the white mountains with the latter seeing snow
showers. The upper level low will cause gusty conditions Monday
with 20-foot winds out of the west blowing near 20 mph and gusts
up to 35 mph.

Twc watches warnings advisories None.

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.
