TERRAIN DRIVEN WINDS
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
.DISCUSSION...A weather system moving through the region today
will result in cooler temperatures and breezy conditions, especially
to the south and southeast of Tucson. Moisture moving out ahead
of the cold front will result in isolated light rain showers (just
enough rain to wet the ground) late this afternoon into this
evening. Expect elevated 20-foot winds from the west/southwest
around 15-20 mph with gusts 30-35 mph over portions of eastern
Santa Cruz and Cochise counties this afternoon and early this
evening. Otherwise, Min RH values will be in the 25-35 percent
range through Friday, lowering to 20-30 percent this weekend. Dry
weather returns to Southeast Arizona Thursday into next week with
high temperatures returning to above seasonable levels next week.
