Synopsis
Strong high pressure stationed over the east pacific will keep dry
conditions over the region through the end of the month.

Temperatures will warm the remainder of the week with afternoon
highs rebounding back into the lower 70s for most desert
communities. A few weak, but dry upper level disturbances will sweep
through the region early next week; however only bringing periods of
gusty winds and high level clouds.

Discussion
After a chilly day yesterday, temperatures will be on the rise
over the next few days as sunny skies help to slowly modify the
airmass that will mostly remain in place. A highly amplified
eastern pacific to our west and a deep polar vortex centered over
the great lakes and southeast canada will provide a blocking flow
regime over the southwestern u.S. Through the weekend and likely
through next week. This will provide a persistent dry
northwesterly flow over the desert southwest with no chances for
rain for the foreseeable future.

Upper level heights over our region will remain above
climatological normals through next week, but multiple weak
shortwaves coming down on the east side of the pacific ridge will
at times provide slight cooling aloft. 500mb heights today through
next week will range anywhere from 570-582dm, but this will not
translate to any significant swings in daily temperatures. The
first noticeable shortwave trough will quickly swing through
Friday night followed by a strong surface high that sets up over
the great basin. The resultant tightened pressure gradient over
the region will bring breezy to localized windy conditions to much
of the area on Saturday. The strongest wind gusts are forecast
across southern california, but as of right now winds look to fall
short of advisory level. A second shortwave for early next week
now is less pronounced among the models and also farther east.

This has allowed forecast temperatures to be raised for early next
week, keeping highs mostly in the lower 70s (a few degrees above
normal) and lows generally near normal.

Aviation
South-central arizona including kphx, kiwa, and ksdl and
southeast california southwest arizona including kipl and kblh:
no aviation impacts are expected through the TAF period as clear
skies persist under dry northwest flow and high pressure aloft.

Winds will generally follow diurnal trends and remain AOB 6 knots
except at blh where n-nw winds up to 10 knots will be possible on
Thursday afternoon. Easterly winds at the phoenix sites will
persist through early afternoon before trying to back to the w-nw
through early evening, but winds will remain light regardless.

Aviation discussion not updated for amended tafs.

Fire weather
Friday through Tuesday:
dry conditions under high pressure aloft will dominate through
Monday bringing above average temperatures to the desert southwest.

A wave moves through Monday night and Tuesday, bringing cooler and
drier air to the region. Through Monday, humidity readings will
remain fairly stable dipping into the 15 to 25 percent range each
day. On Tuesday, humidity levels will remain below 15 percent across
the lower deserts. Combined with strong northerly winds on Tuesday,
the lower humidity levels will approach critical conditions,
especially along and west of the lower colorado river valley.

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.
