What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Update Updated aviation and fire weather discussions.

Synopsis
High pressure will build across the region this week resulting in a
rapid warming trend with many lower desert communities exceeding
the 110 degree threshold both Thursday and Friday. Some cooling
is anticipated over the weekend as a weak low pressure system
passes north of the region. There are no signs of rainfall through
early next week.

Discussion
Latest streamline analysis shows a well-defined anti-cyclonic flow
in the eastern pacific. SREF continues to indicate that the ridge
will build eastward while amplifying over the desert southwest
through Friday. Consequently, steady height thickness rises will
translate into a warming trend with the hottest conditions of the
year expected Thursday Friday. Temperatures today will still be
relatively cool before the above normal temperatures return for
Wednesday.

Latest forecast is weighted heavily towards the national blend and
the ECMWF ensemble mos. Forecast high of 111 degrees is a good bet
in phoenix for Thursday, though uncertainty increases Friday as the
strongest height temperature anomalies retreat into the eastern
pacific. The median of the multi-model ensemble equates to a high
temperature around 112 degrees in phoenix Friday, though the latest
gfs suggests an increasing influence from a weak trough to the north.

Nevertheless, full insolation is anticipated and an excessive heat
watch will be issued for portions of the area Thursday Friday,
including the phoenix metro area.

Operational models have come into better agreement for the weekend,
depicting a separate, but stronger vort MAX dropping southeastward
through the intermountain west. Main impact across our area will be
a cooling trend along with seasonably breezy conditions each
afternoon Friday through Sunday. Early next week, models are in
generally good agreement that the monsoon high will emerge near the
az nm border. This will ultimately mean that the seasonably hot
conditions will return, but pops will remain more or less near 0
percent.

Aviation
South-central arizona including kphx, kiwa, and ksdl and southeast
california southwest arizona including kipl and kblh:
moderate dry westerly flow aloft will continue to provide clear
skies at the TAF sites for the next 24 hours at least. Winds will
tend to be on the light side, favoring the typical diurnal patterns
in the greater phoenix area and leading to lot of light variable
winds over the western deserts including kblh and kipl. No aviation
impacts are expected for at least the next 24 hours.

Aviation discussion not updated for amended tafs.

Fire weather
Thursday through Monday: unseasonably hot weather will return to the
districts Thursday into Friday with hotter deserts exceeding the 110
mark before modest cooling back towards more average late june
temperatures returns over the weekend. Minimum afternoon humidity
values will fall into the single digits through Friday, then closer
to a 10-20% range over the weekend. Overnight recovery will be poor
to fair. Light west winds Thursday may become locally stronger
Friday into Saturday with the passage of a weather disturbance to
the north, but otherwise typical afternoon upslope gustiness will be
common during the period. There are no sign of rain for the
districts through early next week.

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.
