Synopsis An area of low pressure over eastern new mexico
will continue to move away from the region, with dry conditions and
a warming trend today and Thursday. The next system will bring
another chance of showers mainly northeast of tucson Friday through
Sunday, along with strong and gusty winds on Friday. A return to
cooler temperatures Friday and Saturday, then near normal
early next week.

Discussion Latest WV satellite imagery shows the upper low that
has been impacting our area continues to push off to the east and is
now located across eastern new mexico. Southeast arizona is under
northwesterly flow aloft with mostly clear skies except for the
white mountains where some residual wrap around moisture persists.

With the low moving away and increasing heights and thicknesses
today under sunny skies, expect temperatures to warm to seasonable
levels. Winds will remain breezy today, especially around safford in
the upper gila river valley.

Shortwave ridging will crest across the area tonight into early
Thursday ahead of another stronger trough that will impact the area
Friday into the weekend. With the southwesterly flow on Thursday,
temperatures will be even warmer with highs running about 6 to 9
degrees above normal. Expect just a few afternoon breezes on
Thursday as the pressure gradient starts to tighten ahead of the
next system.

The 00z models are in pretty good agreement with the next trough
that will deepen into an upper low and track from the great basin on
Thursday towards the four corners region on Friday and then slowly
dropping south and east Saturday and Sunday across new mexico. A
surface cold front will move through the area during the morning on
Friday, though perhaps into the early afternoon across far eastern
areas. Most of the deterministic guidance along with the sref/gefs
keeps the frontal passage dry but the ECMWF remains insistent on a
light QPF along the front as it draws in some moisture from the gulf
of california. Have opted to keep most of the forecast area below
mentionable pop thresholds except for graham and greenlee county but
future shifts will need to continue to monitor. Otherwise, with the
upper low to our north and an enhanced pressure gradient expect
breezy to windy conditions Friday afternoon, with the strongest
winds east of tucson potentially exceeding advisory thresholds.

Temperatures will be cooler area-wide Friday with highs about 10 to
15 degrees colder than Thursday.

Some wrap around moisture is expected mainly northeast of tucson on
Saturday and with a potential disturbance on the backside of the
upper low, some showers are possible once again for graham and
greenlee counties. Most of the moisture should be off to our east on
Sunday but this will depend on just how fast the upper low moves
away from the area. Regardless, expect another cool day to start
april on Saturday with temperatures moderating on Sunday to near
normal as ridging starts to build in from the west. Thereafter, the
active pattern continues with another trough likely by late Monday
or Tuesday. Limited moisture again with the expected trajectory to
our north but winds could be on the breezy to windy side Monday and
Tuesday. Still plenty of time to iron out those details.

Aviation Valid through 30/12z.

Skc areawide. Sfc wind less than 10 kts thru 29/18z. Aft 29/18z,
nwly sfc wind at 8-16 kts, with the strongest wind in the upper gila
river valley near ksad. Aviation discussion not updated for taf
amendments.

Fire weather Afternoon breezes will continue today and
Thursday along with warmer temperatures. Another weather system will
then move in late Friday with gusty winds. Red flag conditions
possible Friday afternoon across far southern fire weather zone 152.

This system will also bring a chance of showers mainly northeast of
tucson Friday through Sunday.

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.
