Synopsis
High pressure building in from the west will continue a gradual
warming trend across the region through the middle of the week, with
high temperatures rising well above 100 degrees at many lower desert
locations. Somewhat cooler temperatures are likely to return by the
latter portion of next week as low pressure once again moves into
the western us.

Discussion
Afternoon highs today easily topped 100 degrees across the lower
deserts with some locations across southeast california and
southwest arizona reaching or topping 105 degrees. A barely
noticeable shortwave trough currently moving through southern
arizona is bringing a brief period of mainly high clouds, but
anticipate skies to gradually clear before sunrise. Did some minor
upward adjustments to sky conditions for tonight to match current
conditions, but the rest of the forecast is on track.

Previous discussion
A trailing and elongated shortwave off the large upper low near
the great lakes is moving through northern arizona and bringing
our eastern CWA some scattered cumulus clouds. The pacific upper
ridge still remains situated off the west coast and will continue
to push eastward, with heights peaking over our region tomorrow
and Wednesday. Highs tomorrow will range from 105 to 110 from
western arizona westward and from 100 to 106 across south-central
arizona. On Wednesday, temperatures will be near or just a degree
or two warmer than Tuesday. While these temperatures are above
seasonal normals, atmospheric parameters of heights and temps are
not outside of seasonal naefs/esrl percentile ranges. Heatrisk
levels with these temperatures do rise into the moderate to
borderline high categories and given the recent stretch of cooler
weather over the previous week, this warming could catch folks
off-guard.

Temperatures Thursday through next weekend will return to more
seasonal readings as long-wave troughing returns over the western
conus. Lowering heights and slight cool advection will create
gradient driven wind increases, especially across the peninsular
ranges between san diego-el centro Wednesday and then regionally
on Thursday. Gusty surface winds, west to southwesterly in nature,
will sweep into the area and could generate some patchy blowing
dust at times Wednesday for the imperial area and then across
southeast ca for Thursday. High temperatures tumble to readings
100 degrees or cooler Thursday and could stay below triple digit
readings through the weekend as longwave troughing holds over the
region, keeping elevated thicknesses and warmth removed from the
area.

Aviation
South-central arizona including kphx, kiwa, and ksdl, and southeast
california/southwest arizona including kipl and kblh:
no aviation concerns through the TAF period. Winds will remain
light and follow normal diurnal headings. Sct to bkn mid and high
clouds through around midnight will gradually push to the south
leaving generally clear skies for Tuesday.

Aviation discussion not updated for amended tafs.

Fire weather
Thursday through Monday:
westerly wind speeds will be strongest on Thursday, when gusts up
to 35 mph (locally stronger) are forecast to occur. This will
likely create elevated fire weather conditions, especially across
southeast california and the lower colorado river valley where the
combination of relative humidities below 15 percent and gusty
winds will coincide. Winds will weaken into Friday, but still
remain slightly breezy. Over the weekend, wind speeds will be
light area-wide as high pressure builds over the great basin.

A minor cooldown will occur through Saturday, with highs in the
low to mid 90s forecast each day across the lower deserts. A
warming trend will then commence on Sunday, with high
temperatures in the lower 100s making a return by Monday.

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.
