Update Aviation and fire weather discussions.

Synopsis
A dry airmass will remain over the region through the rest of the
week with temperatures moderating closer to average. Though high
temperatures will finally drop below 110 degrees, readings will
still end up in a slightly above normal range through early next
week. Skies will remain mostly clear as the monsoon wind pattern
has yet to be established and storm activity will stay well south
across mexico.

Discussion
Large scale troughing edging southward across the pacific
northwest and the great basin has allowed for a significant drop
in 500mb heights from 592dm yesterday to around 588dm currently.

The slight cooling over the past couple days will continue today
with highs over most lower desert spots dropping below 110
degrees. The dry air that has already overtaken the region will
likely persist through the rest of the week resulting in good
nocturnal cooling and overnight lows mainly in the 70s except for
central parts of phoenix.

Later this week, 500mb heights do begin to increase a bit as the
troughing to our north shifts over the central and eastern u.S.

After highs just below 110 through Friday, we should see a couple
degrees of warming on Saturday with the higher heights resulting
in highs around 110. Although 500mb heights stabilize this
weekend near 592dm and stay there into early next week, a slight
boost in low level moisture (afternoon surface dewpoints 35-40
degrees) should keep highs just below 110 Sunday through Tuesday.

This moisture uptick will however still be insufficient for any
monsoon activity to be seen across the area as both the GFS and
european are in good agreement keeping low level flow either out
of the west or north through next Wednesday. There are indications
we may manage to see a switch to southeasterly low level flow
late next week which could be enough to bring at least a low grade
monsoonal moisture flow out of northern mexico.

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.
