Synopsis Expect gusty winds this afternoon ahead of a low
pressure system moving into the four corners region. This system will
also bring isolated snow showers across the white mountains tonight
into Tuesday morning, followed by much cooler temperatures area-wide
Tuesday. Dry conditions with a warming trend will prevail Wednesday
into next weekend.

Discussion Dense cirrus clouds continue across a large part of
the forecast area this morning thanks to the uplift off the higher
terrain of the northern baja area. Looking at the upstream moisture
feed on water vapor imagery this looks like it will continue several
more hours before shifting to the southeast and I updated the grids
to account for this. This has had an impact on temperatures this
morning and it it continues too long will also impact the depth of
mixing and resultant wind speeds today. There remains a wide spread
in guidance with respect to wind speed potential with this system and
it will be interesting to see how it plays out today. Currently have
a wind advisory across eastern parts of the forecast area and
adjustments were made to the wind in this area to better match the
wind speeds to the headline. Updates already sent and will look at
later periods this afternoon although it will be a relatively quiet
period.

Aviation Valid through 22 18z.

Bkn-ovc clouds above 20k ft agl, gradually becoming few-bkn clouds
at 4k-8k ft agl aft 21 20z then few-sct 5-9k ft agl after 22 03z.

Isolated -shsn in the white mtns northeast of ksad aft 21 23z, with
dry conditions elsewhere. Surface wind increasing late this morning
and early afternoon with swly-nwly surface wind at 12-25 kts and
gusts to 30-40 kts between 21 19z and 22 03z. The strongest wind
speeds will occur east of ktus in the vicinity of kdug, ksad and
kalk. Slowly diminishing surface wind aft 22 03z. Aviation discussion
not updated for TAF amendments.

Fire weather Minor fire weather concerns today.

Dry and windy conditions will occur today and while the overall fire
danger is not high, the burning index will be high due to winds and
rh levels, meaning the gusty winds may cause minor fire control
problems in areas of abundant dead grass this afternoon. The
westerly winds will continue into the early evening before easing.

Otherwise, isolated snow showers are expected in the white mountains
tonight and Tuesday with dry conditions thereafter area wide. After
this evening, the 20-foot winds will mainly be less than 15 mph.

Prev discussion issued 310 am mst Mon jan 21 2019
strong and gusty winds will be the main weather story today as a low
pressure system approaches the region. A wind advisory has been
posted for eastern cochise and graham counties into the white
mountains from 11am to 7pm mst today. A few showers will also
accompany this system across northeast arizona into the white
mountains tonight into early Tuesday. The system will usher in a much
cooler air mass with temperatures dropping a few degrees below
normal Tuesday and Wednesday. Another system will clip extreme
northeast arizona. Otherwise, a ridge of high pressure aloft along
the west coast will provide the area with dry conditions and above
normal high temperatures Thursday into the weekend.

Twc watches warnings advisories
Wind advisory until 7 pm mst this evening for azz508>512.

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.
