Synopsis A weak weather system will move across the region
through Thursday. However, moisture will be insufficient for
rainfall. Slight cooling will take place through the middle of
the week, but temperatures will remain at or above normal. There
will be off and on periods of high clouds Friday through Sunday
before a very slight chance of showers develops next Monday.

Discussion A low splitting under the larger scale flow will
push across the area immediately south of the border tonight into
Wednesday. The best dynamics and moisture will be associated the
track of the low across northern baja and central to southern
sonora. No significant rain chances, but a sprinkle or two is not
out of the question. Plenty of mid to high cloud across our area
this afternoon, with some clearing from the west later tonight.

The higher latitude portion of the trough will generate some gusty
winds ahead of a cold front passing through the state Wednesday
night, especially near the colorado river and westward. At this
point it looks to stay below wind advisory levels. Cooler Thursday
behind the front.

A ridge will build in from the west the last half of the week,
with daytime highs back to several degrees above average over the
weekend.

The high frequency pattern will continue with another trough
pushing onshore Sunday night into Monday. The GFS grabs onto an
impulse embedded in the southwesterly low ahead of this system
and brings a few showers to the area as early as Sunday night,
with a solid split directly through southern california and
western arizona Monday night into Tuesday. The ECMWF maintains a
more consolidated flow with little in the way of significant
precip chances. While it may (as is often the case) be
underestimating the moisture associated with the impulse embedded
in the southwesterly flow, it seems to be handling the larger
scale flow early in the week a little better. As such we went with
a slight undercut of the nbm.

Aviation
South-central arizona including kphx, kiwa, and ksdl:
little to no aviation impacts through Wednesday as thick 20k ft
cigs eventually clear overnight. Light east winds will prevail
through most of the day though confidence is moderate that a
switch to a weak westerly component will occur very late in the
afternoon and persist through the evening.

Southeast california southwest arizona including kipl and kblh:
no aviation concerns through Wednesday morning as thicker 20k ft
cigs start to clears. Sfc winds will favor a NW direction though
will remain light and could be variable in direction heading into
this evening. Winds may start to increase late Wednesday afternoon
ahead of a front pushing through the region Wednesday night.

Aviation discussion not updated for amended tafs.

Fire weather
Thursday through Monday:
a cold front will pass through the area Wednesday night into
Thursday bringing elevated wind gusts to the region. Breeziest
conditions will occur overnight, with gusts to 25 to 30 mph near
and west of the colorado river and across ridge tops in southwest
and south-central arizona. Through Friday, minimum afternoon
humidity levels will fall below 20 percent. Saturday through
Monday, minimum humidity levels will be on the increase. On
Saturday, levels will fall into the 15 to 25 percent range and by
Monday levels will only fall into the 30 and 40 percent range.

Overnight recoveries will be good to excellent.

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.
