Synopsis A few thunderstorms mainly near mountains east to south
of tucson Sunday afternoon and evening. Strong high pressure aloft
will limit thunderstorms to mainly near the white mountains Monday.

The strong high pressure system will also bring hotter than normal
temperatures Monday into Tuesday, with record highs for some
locations. Thunderstorm chances increase as temperatures moderate
during the latter part of the new week.

Discussion What few thunderstorms that managed to develop near
the international border this afternoon had pretty much dissipated
or remained in sonora, mexico. Updated the forecast to drop or lower
rain chances for tonight. Otherwise, high pressure aloft will
strengthen over the region resulting in a hotter and more stable air
mass which will limit thunderstorm activity the next few days.

Excessive heat can be expected early this coming week, with heat
warnings already posted for Monday and Tuesday. Please refer to the
additional sections for more details.

Aviation Valid through 23 06z.

Isolated -tsra -shra mainly near mountains east to south of ktus
Sunday afternoon. Otherwise, few to occasionally bkn clouds at 6k-
12k ft agl through Sunday afternoon. Surface wind variable in
direction mostly less than 12 kts into Sunday morning. Aviation
discussion not updated for TAF amendments.

Fire weather A few thunderstorms mainly near mountains east to
south of tucson Sunday afternoon and evening. Any thunderstorms
Monday will mainly be limited to the white mountains northeast of
safford. Thunderstorm coverage will gradually increase starting
Tuesday and continuing the rest of the upcoming week. Aside from
gusty thunderstorm outflows, 20-foot winds terrain driven generally
under 15 mph.

Prev discussion The 21 12z gfs ECMWF and their respective
ensembles remained consistent with depicting a 598-600 dm high to
become centered near the east-central arizona west-central new
mexico state line by Monday afternoon. Any showers tstms Monday
should be confined to mainly near the white mountains.

The main concern regarding the strong high pressure system over the
southwestern CONUS by Monday and continuing into Tuesday will be
record or near-record high temperatures across the area. Based on
various 21 12z guidance, no changes of significance were made to the
inherited forecast highs Monday into Tuesday. As such, the excessive
heat warning remains in effect from 10 a.M. Monday to 8 p.M. Mst
Tuesday for azz501>509, or the forecast zones below 5000 feet
elevation.

Thereafter, the deterministic gfs ECMWF depict a very gradual
westward shift of the upper high during the latter part of the
upcoming week. The models depict a gradual increase in thunderstorm
coverage to occur across this forecast area as the storm steering
flow becomes increasingly easterly. The upshot is that isolated to
scattered coverage of showers tstms should return, especially
Thursday into next Sunday.

After the very hot daytime temps Monday and Tuesday, and for
portions of the area Wednesday, high temps Thursday into next
Saturday are forecast to moderate closer to seasonal normals.

Twc watches warnings advisories
Excessive heat warning from 10 am Monday to 8 pm mst Tuesday for
azz501>509.

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.
