Synopsis
A weak wave along the southern fringes of a low pressure system
will move across our forecast area through Friday morning,
bringing thicker cloud cover and virga light sprinkles. High
temperatures will fall back into the lower 70s today and tomorrow
before warming back up over the weekend under high pressure. High
pressure will peak Tuesday with high temperatures approaching 90
degrees in the lower deserts.

Discussion
Currently, the center of a closed low is moving into southern
nevada. A weak wave will move along the southern fringes of the
low, exiting the state by Friday morning. As this wave crosses southeast
california and the central and northern portions of arizona, we
can expect some thicker clouds and virga (mainly across the
northern fringes of riverside, la paz, maricopa, and gila
counties in our forecast area). The most notable effect from this
system will be the colder air that will continue to filter into
the region. Highs today will be in the low 70s, with lows tonight
dropping into the 40s in most lower desert locations. The cold
spot in our forecast area this evening will be hilltop, az, with a
low in the upper 20s.

For the rest of the forecast period, this weekend into the middle
portion of next week, we are looking at dry conditions as higher
pressure aloft builds into the desert southwest. A weak trof will
pass by well to the north over the weekend, but we should still
see high temperatures over the lower deserts climb into the upper
70s and phoenix may even hit the 80 degree mark by Sunday.

For the early portion of next week, another pacific trof will
approach the west coast and as it does, it will really pump up the
ridge out ahead of it and across the desert southwest, leading to
very warm high temperatures. Highs will reach low to mid 80s
Monday and then climb to around 90 across warmer locales Tuesday
despite a significant increase in high cloud forecast to
overspread the area ahead of the approaching trof. So, phoenix may
hit the 80 degree mark on Sunday and then the 90 degree mark 2
days later. The ridge will weaken a bit Wednesday as some short
wave energy breaks off from the trof and moves inland and into the
desert southwest but desert highs will stay above normal and
lower mostly into the middle range of the 80s.

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.
