20-FOOT WIND FORECAST OF `LIGHT WINDS` INDICATES MAINLY
TERRAIN DRIVEN WINDS
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
.DISCUSSION...Dry and hot weather will prevail through Monday.
Temperatures continue to rise and peak at 8 to 14 degrees above
normal Wednesday and Thursday. A very low grade monsoon pattern
returns starting Tuesday initially along the International Border
and then gradually expands to the rest of southeast Arizona.
However, that will only result in slight (10-20%) chances through
Friday for most locales before a possible uptick in storms next
weekend. Min RH values around 8 to 15 percent through Thursday then
15 to 25 percent starting Friday.
