Synopsis Very hot temperatures will continue into this weekend.
A little drier today before a more favorable pattern provides
increasing thunderstorm chances, with scattered afternoon and
evening thunderstorms Sunday into the middle of next week.
Discussion The bulk of earlier morning convective debris
cloudiness has mostly dissipated at this time. However, partly
cloudy skies still prevail south-to-southeast of tucson with sunny
skies or mostly sunny skies elsewhere. Several hrrr solutions and
the univ of az wrf-nam suggests that isolated thunderstorms may
occur this afternoon across far southeast sections; or, particularly
in the vicinity of the southern portion of the chiricahua mountains,
and perhaps even further southwest to near douglas. Otherwise, the
main emphasis continues to be the very hot temperatures predicted to
occur again this afternoon.
The official forecast handles this scenario well, so no updates are
necessary at this time. Please refer to the additional sections for
Aviation Valid thru 24 18z.
Isolated -tsra may occur in the vicinity of kdug this afternoon.
Forecast confidence is too low to have vcts in the kdug taf.
Otherwise,VFR conditions into Saturday morning. Surface wind this
afternoon northwesterly 10-25 kts with gusts to near 35 kts. The
strongest wind will be east of ktus and especially in vicinity of
ksad. Smoke from wildfires may bring MVFR conditions to flight paths
and airfields in the area through the period. Surface wind mainly
under 12 kts at other times. Aviation discussion not updated for taf
Fire weather Dry conditions will prevail across much of the
area through Saturday. The exception will be in the higher terrain
along the new mexico border and in the white mountains where there
is a slight chance of showers and thunderstorms. A more favorable
pattern for thunderstorms will then prevail Sunday through next
Wednesday. Expect scattered afternoon and evening thunderstorms,|
especially from tucson south and eastward. However, the coverage of
thunderstorms Monday into Tuesday will also include the eastern
portion of fire zone 150.
20-foot winds will generally be terrain driven and less than 15 mph.
The exception will be elevated northwest winds through the gila
river valley near safford into this afternoon, with speeds of around
20 mph and gusts to 30 mph. Additionally, any convection which
develops this weekend and next week will be capable of producing
gusty and erratic winds.
Prev discussion 304 am mst We're still seeing some debris cloud
this morning from the convection yesterday and last night near the
border. Trends will be down a little more today with weak drying in
a temporary northwesterly flow.
The ridge over the desert southwest is weakening, but still very
potent as we see one more solid reconsolidation overhead Saturday.
A weaker flow will also see increasing mid level moisture slip back
into the area with as evidenced by a strengthening 700hpa theta-e
ridge through sonora and southeast arizona by Sunday.
Not as hot to start the new week with weakening high pressure and
the increasing moisture. Some solid thunderstorm days Monday-
Wednesday, but the deeper moisture will still not be in position to
provide the more prevalent heavy rainfall wet micro-burst style
storms. Another batch of early season storms that generate
impressive outflows and dry lightning with limited significant
The ridge will weaken and drop into a blocking position with a more
active higher latitude pattern the second half of the new week. That
will depress the most significant thunderstorm activity back into
mexico for a few days.
Twc watches warnings advisories
Heat advisory until 7 pm mst Sunday for azz510>514.
Excessive heat warning until 7 pm mst Sunday for azz501>509-515.

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.
