Update Updated aviation discussion.

Synopsis
An exiting weather system today will bring breezy conditions with
warming conditions west of phoenix. Building high pressure this
weekend will result in a significant warming trend with high
temperatures reaching into the middle 90s by Monday. The very
warm and dry conditions will last through the middle of next week
with highs nearing 100 degrees over the warmest desert locations.

Discussion
Winds have diminished since midnight with effective decoupling of
the boundary layer taking place. The upper low is currently
centered over southern utah, but a large area of wrap-around mid
level moisture reaches south into central arizona. The upper low
will continue to track eastward today passing through the four
corners area this afternoon. Just enough moisture and weak lift
passing through northeast arizona may bring a few showers to far
eastern gila county early this evening, but high-res models
overall show the bulk of the showers missing our area. Winds today
will become breezy by late morning, lasting through the afternoon
hours, but gusts will generally stay below 25 mph. Temperatures
today will remain below normal across south-central arizona, but
increasing heights to our west will lead to highs reaching into
the middle 80s across southeast california.

The upper low will exit well to the east on Saturday with 500mb
heights quickly building to around 580dm over much of the desert
southwest. This will allow for further warming and highs Saturday
in the upper 80s to lower 90s. A weak shortwave trough moving
east through baja Saturday night and across northern mexico on
Sunday will temporarily bring an increase in upper level moisture
and high cloudiness into the desert southwest. Skies will clear
out later Sunday as the shortwave moves into southern new mexico,
leaving weak westerly flow and ridging over the desert southwest.

Highs will warm a few more degrees into Monday with readings
topping out mostly in the middle 90s. Another weak southern stream
shortwave trough is seen moving through our region for next
Tuesday, but as with the first one only some high cloudiness is
expected with no change in temperatures.

Substantial model spread is seen across the southwest u.S. For
the latter half of next week. Overall model consensus shows a deep
upper level low potentially becoming cut-off from the main flow
during the period. Very little change is seen across the desert
southwest for next Wednesday with continued very warm temperatures
and dry conditions. Forecast confidence is low thereafter as
temperatures will be highly dependent on how long the upper low
sits off the west coast. For now it looks like the well above
normal temperatures are to remain over the region through at least
next Thursday, possibly longer.

Aviation
South-central arizona including kphx, kiwa, and ksdl:
breezy westerly winds will once again be present today. Through
sunset, wind speeds will be around 10 to 15 kts with gusts up to
20 kts. Winds will return back to a light diurnal regime
overnight tonight. Skies will be clear.

Southeast california southwest arizona including kipl and
kblh:
at kipl, winds will be out of the northwest AOB 5 kts through
sunset. Thereafter, winds will generally become light and variable
but primarily hold on to a west-southwest wind direction. At kblh,
winds will be out of the southwest with some breeziness up to 20
kts possible through sunset. Thereafter, speeds will reduce
significantly, becoming light and variable by 10z. Skies will
remain clear at both TAF sites through the period.

Aviation discussion not updated for amended tafs.

Fire weather
Sunday through Thursday...

a pattern of warm and dry weather will predominate the region
throughout the period. Above normal MAX temps in the 90s and min rh
values in the single digits are expected to persist through
Thursday. Otherwise generally light winds with occasional
seasonable breezes can be expected to occur on most afternoons.

Overnight recovery is expected to remain poor to fair.

GOES Local Image of Southwest    EDIT
NOTE: East coast views moved to GEOS-16. They are experimental and not well supported by NOAA so they may not be correct so be warned. This change required redoing a large amount of the GOES code. If the image you are expecting is not showing, please let me know. You may need to use the EDIT function to update your location.

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.
