Synopsis Cooler today and Friday before high pressure brings a
warming trend over the weekend and into next week. High temperatures
will peak Tuesday of next week, with readings across southeast
arizona topping out 8 to 12 degrees above normal. Cooler and breezy
by the end of next week.

Discussion An upper low was currently centered near barstow,
california early this afternoon. This low will track northeastward
into central utah during the day Friday. The low level moisture
field and associated dynamics have primarily shifted north of our
forecast area across the northern half of arizona attm. Still expect
isolated shower activity to occur in the white mountains today with
a slight chance of a stray shower Friday. However, the rest of the
forecast will remain dry, with mainly high level cloudiness being
advected into southern arizona around the upper low circulation.

Otherwise, cooler daytime temperatures are expected through Friday,
with highs topping out 4-7 degrees below normal. There will also be
some afternoon breeziness, mainly over the eastern half of the
forecast area this afternoon and then again Friday afternoon.

By Friday night into Saturday the upper low tracks well east of the
region into the central plains, with zonal flow across the
southwestern united states in the lows wake. This will allow
temperatures to rebound to near normal levels Saturday and Sunday
with periods of high clouds.

The ensemble forecast mean depicts a strengthening ridge of high
pressure across the desert southwest early next week. This will
result in high temperatures running 8-12 degrees above normal, with
Tuesday being the warmest day. Readings will approach the 90 degree
mark on Tuesday across the tucson metro area.

A series of systems will then move across the great basin and
northern tier of states mid to late next week. This will suppress
heights and lower daytime temperatures across southeast arizona 3-5
degrees both Wednesday and Thursday, which would lower readings back
to near normal levels late next week. However, the big story for
southeast arizona with these systems will be the breezy to windy
conditions as the systems track north of the area.

Aviation Valid through 23 00z.

Isolated -shra in the white mountains northeast of ksad. Otherwise,
vfr ceilings and visibilities. Wly nwly surface wind at 8-16 kts

Aft 22 19z, wly nwly surface wind at 8-16 kts and some gusts to near

Fire weather Isolated showers are expected in the white mountains
through the evening hours tonight with a slight chance of a stray
shower on Friday. Otherwise, dry conditions will be on tap for the
rest of the forecast area through Friday. Dry conditions will occur
areawide this weekend and into the middle of next week. Breezy west
to northwest winds across eastern portions of the forecast area this
evening and then again Friday. 20-foot winds will then be terrain

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.
