Synopsis Dry conditions through Friday except for a few
thunderstorms this afternoon southeast of tucson. Isolated to
scattered thunderstorms will then return mainly east to south of
tucson by early next week. Seasonably hot daytime temperatures
will prevail into this weekend.

Discussion
Mid morning water vapor imagery reveals dry air across the region,
with a sharp gradient of dry low level air cutting across arizona
from north to south. This is also reflected in surface dewpoints as
values are generally in the mid 20s across western arizona while
lingering in the upper 40s lower 50s east of tucson. Nearly all
available incoming 12z guidance has captured this trend well and
indicate the drying trend will continue through the
afternoon evening hours. Ncar ensemble suggests convection
across cochise and santa cruz co's later today. Past few runs of the
hrrr are a bit less enthusiastic and keep storms confined to new
mexico and mexico. Until bl moisture is sufficiently scoured out
late tonight or tomorrow, it still seems plausible that mountain
showers and storms will develop, albeit with far less areal coverage
than what has been seen as of late.

Inherited digital forecast grids look good across the board and
agree well with 12z model and 09z ensemble trends. Only minor
changes will be made based on observational data.

Aviation Valid thru 28 18z.

Skc-few clouds at 10-15k ft agl from ktus west, and few-sct clouds
at 8-12k ft agl east and south of ktus thru the forecast period.

Isolated shra tsra this afternoon near the int'l border including
kdug and kols. Sfc wind variable at less than 12 kts this morning.

Sfc wind this afternoon 12-16 kts with gusts of 20-25 kts possible,
especially at ktus ksad. Aviation discussion not updated for taf
amendments.

Fire weather Isolated thunderstorms across the southern portion
of fire weather zone 152 this afternoon. Dry conditions are then
expected area-wide through Friday, with isolated to scattered
convection returning to a few spots Saturday into early next week.

Breezy west to northwest 20-ft winds of 15 to 20 mph are likely
during the afternoon hours through Thursday, especially in the upper
gila river valley. Speeds will then generally remain less than 15
mph into early next week. However, periods of erratic gustiness may
occur due to strong daytime heating and or thunderstorm outflows.

Prev discussion
As high pressure shifts south and southwest of the
area, we will see a drier westerly flow along with temperatures
slowly falling closer to average values for late june. Today much
like yesterday, with temperatures below excessive heat levels, but
still several degrees above average.

Still a little mainly mid level moisture in the atmosphere, but
precipitable water values will start to slip below 1 inch today,
while surface dew points mix into the 30s or even upper 20s later
this afternoon.

The trends in western mexico are continuing upward over the past
24 hours. We need the high to shift into a more open position to
our east, and signs are that will happen early next week. That
should in turn reintroduce easterly wave activity at a higher
latitude across mexico and support deeper moisture intrusions.

Thunderstorm trends will be up early next week, but it's unclear
how far north things will progress. A fairly safe bet that at
least portions of santa cruz and cochise counties will see
activity return by Sunday.

Twc watches warnings advisories None.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
