.DISCUSSION...Today through Next Wednesday

Hot temperatures remain across the region as high pressure
continues through today. The Extreme Heat Warning out for much of
the area will continue through tomorrow with temperatures about
5-10 degrees above normal. These high temps coupled with little
relief at night make the heat much more dangerous and has
contributed to major HeatRisk aross the lower elevations of the
Mojave Desert.

As the ridge of high pressure breaks down a bit on Thursday
afternoon, a shortwave will move into the area. This will bring
increased winds, causing dangerous fire weather conditions. A Red
Flag Warning is in effect for Thursday and Friday for much of
southern Nevada and Mohave County. Dangerous fire weather
conditions will continue through Saturday over a smaller area.

As the Pacific trough moves in over the weekend, winds will
decrease on Sunday and much cooler temperatures will bring some
well needed relief from the extreme heat. Below normal
temperatures will make a brief appearance Sunday and Monday before
they return to near normal by Tuesday across the area.
