   Friday through the weekend.

.DISCUSSION...Today through Monday.
High pressure over the southern US will gradually expand and 
strengthen over the Desert Southwest mid to late week. This will 
result in rapidly warming temperatures Wednesday and Thursday with 
temperatures climbing to around 8 to 10 degrees above normal. As a 
result, an Extreme Heat Warning has been issued for Thursday for 
Death Valley, the Las Vegas Valley, Pahrump Valley, Moapa Valley, 
Colorado River Valley, southern Mohave County, and southeastern San 
Bernardino County. Temperatures will begin to trend downward 
starting Friday as a trough pushes into the western US. This will 
allow temperatures to drop about 5 degrees Friday along with an 
additional drop around 2 to 4 degrees Saturday with temperatures 
close to normal by early next week. Generally dry conditions are 
expected, but some weak monsoonal moisture will be pulled northward 
Wednesday and Thursday allowing for at least a slight chance of 
thunderstorms in the Sierra and terrain of the southern Great Basin 
due to strong daytime heating and weak instability.

The aforementioned trough pushing into the western US will bring 
cooler temperatures but also bring increasing southwest winds to the 
region. The strongest winds look to occur Saturday afternoon where 
widespread gusts 25-35 MPH are expected, with over a 50% chance of 
gusts over 40 MPH in the western Mojave Desert. There could also be 
some gusty southerly winds impacting Lake Mohave and Lake Havasu 
this weekend, which could impact boaters with winds and waves.

.AVIATION...For Harry Reid...For the 18Z Forecast Package...Light 
winds generally following typical diurnal directional trends will 
continue through the TAF period. Speeds will generally remain below 
8 knots, although a few gusts of 12 to 15 knots are possible during 
the period of maximum heating this afternoon. VFR conditions will 
prevail through Tuesday with only a FEW to SCT mid- and high-level 
clouds at times. Temperatures should top out right around 100F by 
mid to late afternoon. 

For the rest of southern Nevada, northwest Arizona and southeast 
California...For the 18Z Forecast Package...Favorable aviation 
conditions will persist across the region through Tuesday with winds 
generally following typical daily directional patterns and speeds 
remaining 12 knots or less. VFR conditions will prevail with only a 
FEW to SCT mid- and high-level clouds streaming across the region at 
times.
