Synopsis
Significantly drier air will work into the region starting today
with only a lingering slight chance of showers or a thunderstorm
across the eastern arizona high terrain. Dry and warmer conditions
take over starting Friday as temperatures warm back to above
normal. High temperatures will continue to run around five degrees
above normal through much of next week as readings reach between
101 and 106 degrees over the lower deserts.

Discussion
Nearly all of the shower and thunderstorm activity came to an end
late last evening, but we have seen a few lingering showers since
midnight. Current radar imagery is essentially clear across
arizona with only some light shower activity east of the tucson
area. Water vapor imagery continues to show much drier air working
in from the west, progressing through at least the western half
of arizona. However, boundary layer conditions remain very moist
with surface dew points hovering in the upper 60s to around 70
degrees. The rain cooled air, clearing skies, and near calm winds
may be enough to allow for some patchy fog to develop by sunrise,
especially across pinal county where there were higher rainfall
totals.

The trough axis which is currently over central arizona will
quickly push into new mexico by early afternoon leaving increasing
subsidence aloft and further drying aloft. There should still be
sufficient low and mid level moisture present this afternoon for a
few isolated showers and thunderstorms across southern arizona,
but this activity will mainly be confined to higher terrain areas
east of phoenix. Temperatures today will recover into the upper
90s to around 100 degrees under generally sunny skies.

Building heights aloft will take over across the southwestern
u.S. Starting Friday as the pacific trough lifts into the north-
central u.S. 500mb heights will rise to near 590dm starting
Friday, likely remaining there through much of next week as an
omega block develops. This will allow for warmer temperatures
during the period as highs generally reach between 100-105 each
day. No moisture return is forecast through next week leaving the
region under continued clear to mostly clear skies.

Aviation
South-central arizona including kphx, kiwa, and ksdl:
any aviation weather concerns are dwindling as most of the showers
have moved east of the terminal area. However, an isolated shower
or two cannot be ruled out overnight or in the morning. In
addition, some areas of lower ceilings can be expected, especially
banked along any mountains. Otherwise, the winds will stay
primarily easterly overnight with some periods of variability. A
more typical diurnal wind trend is expected for tomorrow.

Southeast california southwest arizona including kipl and kblh:
there are very few aviation weather concerns through tonight. The
winds will maintain a more easterly component, especially for
kipl, while becoming more southerly for kblh. There will be some
stronger gusts and occasional midlevel clouds.

Aviation discussion not updated for amended tafs.

Fire weather
Saturday through Wednesday:
temperatures will rebound over the weekend and climb several degrees
above seasonal normals next week. A pronounced drying trend will
exist with little to no chance of showers or storms. Minimum
humidity levels in a 15-30% range over the weekend fall more solidly
into the teens next week with some readings into the single digits
over far southeast california by Monday. Overnight recovery will
vary widely from fair to excellent. Winds will remain mostly light
and quite typical for late summer early autumn.

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.
