Persistent heat over the desert southwest will continue to prevail
over our region into Thursday as a strong and broad upper level ridge
centered over southern Nevada remains nearly stationary. Light to moderate
afternoon and early evening thermal breezes can be expected daily through
the outlook period. Hurricane Emily is currently exiting the northern
Yucatan of Mexico this morning. Emily is anticipated to make a second
landfall along the northeast Mexican coast and/or south corner of Texas near
vicinity of Brownsville sometime late Tuesday night/early Wednesday morning.
The northern periphery of Emily's remnant moisture is expected to become
entrained into a developing southeast monsoonal flow over New Mexico/Arizona
near mid week. Some of this moisture is likely to be transported into
southeastern California by Friday. This will likely bring a significant
increase in local mountain thunderstorm activity, mainly in the eastern and
southern portions of our area over the weekend. With a high temperature
reading recorded at Armitage Field yesterday of 114F, we fell short by 1
degree Fahrenheit of the all time record high for the date. The record is
115F, which was set back on July 17th of 1988. However we can take some
solace fore, Furnace Creek at Death Valley, registered a reading of 132F on
the 14th of this month, ( this past Thursday), and 129F on Saturday.
