Update Updated aviation discussion...
As drier air continues to move into the region expect high
temperatures to stay several degrees above normal today. High
pressure aloft will weaken slightly early in the week allowing high
temperatures to drop to near 100; as we move into mid week
temperatures climb again under dry northwest flow aloft and slightly
stronger high pressure aloft. Precipitation and storm chances will
remain very low and are generally not expected through the forecast
period with the occasional slight possibility of very isolated,
short-lived afternoon pop-up showers and storms.
A relatively flat upper level high pressure ridge continued to be
situated across the desert southwest early this morning, with 500mb
heights running around 590dm over southern az. Over the past couple
of days moisture has continued to thin across the area; surface
dewpoints at 1 am were mostly in the 40s (down 6-13 degrees from 24
hours ago) and the pwat in tucson was about 0.5 inches. IR imagery
early this morning showed some patchy mid clouds over portions of
the deserts with a bit of high cloud moving into far southeast
california. Overall skies were mostly clear.
Over the next few days, we will be sitting under a rather zonal flow
aloft as the upper ridge is gradually flattened. It will be a dirty
ridge; moisture has thinned but is still slightly elevated with pwat
running around 1 inch over portions of the lower deserts on a daily
basis. Monsoon moisture still remains rather close by and some of it
bleeds back into the area from the south as lower level flow is more
southerly. We will see enough moisture for some high based cumulus
and patchy mid high cloud but not enough for any thunderstorms -
even over the higher terrain. Early in the week, guidance remains
consistent that a very large trof will settle in over most of the
conus, with high pressure aloft situated over the desert southwest.
Short wave energy dropping southeast along the back side of the
broad trof Tuesday - and thru the 4 corners area - may lead to
buildups over high terrain east of phoenix but pops will stay in the
5-9 percent ballpark. With the ridge flattening and heights
gradually falling off, high temperatures will drop a couple degrees
today into the early part of the week but they should not fall below
the triple digit mark. Expect highs around 100 in phoenix Monday and
For Wednesday into the weekend, high pressure will build a bit over|
the desert southwest as the previously mentioned short wave moves
off to the east. Expect continued dry conditions area wide and high
temperatures climbing slightly and remaining several degrees at
least above seasonal normals. Expect partly cloudy to mostly sunny
skies over the deserts each day. Overall there has been very little
change made to the forecast over the 7 day period, with dry and hot
conditions continuing, and triple digit highs will likely continue
in phoenix for the foreseeable future.
South-central arizona including kphx, kiwa, and ksdl:
easterly winds this morning will become breezy at times before
slackening off early this afternoon. Winds should switch around to
a light westerly wind for a few hours around 00z, but easterly
winds will again take over before midnight. Few to sct clouds will
be common today, but bases should remain above 10k feet.
Southeast california southwest arizona including kipl and kblh:
no aviation weather impacts expected. Generally light, diurnal
winds will continue under partly cloudy skies. A brief period of
southerly breeziness is likely at kblh this afternoon.
Aviation discussion not updated for amended tafs.
Tuesday through Saturday:
temperatures will continue to remain 2-4 degrees above seasonal
normals through the entire period. Mainly dry conditions are
expected, except for a very slight chance (<10%) for a few isolated
showers storms over the higher terrain north and east of phoenix on
Tuesday, as a bit of moisture is briefly pulled northward into the
region. Minimum humidity levels to remain around 10-15 percent for
the lower deserts and 15-25 percent for the higher terrain north and
east of phoenix, but with fair to excellent overnight recoveries.
Winds to mainly remain on the light side (except for some afternoon
gustiness, mostly following the usual diurnal trends.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
