.DISCUSSION...Today through Thursday.



Ridging will remain in place through today, bringing another day of 

temperatures around 10 degrees above normal. Widespread areas of 

Moderate Heat Risk, with pockets of Major Heat Risk in the Las Vegas 

Valley, Colorado River Valley, and Death Valley. We will start to 

see cooling temperatures beginning Saturday as an area of low 

pressure pushes into the Pacific NW, resulting in an elongated 

trough along the western US. The main impact from this trough will 

be increasing southwest winds with speeds generally 20 to 25 mph 

with gusts to around 35 mph, with stronger winds in the higher 

terrain. Due to the combination of strong gusty winds, low relative 

humidity, and critical fuels, a Fire Weather Watch has been issued 

for southern Nevada and northwestern Arizona. Winds will begin to 

subside Sunday over southern Nevada, but remain gusty across 

portions of northwest Arizona. Temperatures will cool an additional 

4 to 7 degrees Sunday putting temperatures close to normal for this 

time of year. A second piece of energy is expected to help deepen 

the trough Monday and Tuesday helping to once again increasing wind 

speeds and keep the ongoing fire weather danger in place. 

Temperatures will also continue to cool with highs on Tuesday and 

Wednesday potentially a few degrees below normal. Generalized 

troughing will persist through the next work week, with a modest 

uptick in moisture on Tuesday. That said, negligible chances of 

precipitation at this time.

.AVIATION...For Harry Reid...For the 12Z Forecast Package...Light

and variable winds will increase slightly and settle in from the 

south-southeast later this morning/early this afternoon. These 

south-southeasterly winds will continue through mid-afternoon when

10 to 15 knot southwesterly winds will pick up, accompanied by 

gusts to around 20 knots. These breezy southwesterly winds will 

continue into the evening hours, with a brief lull around sunset. 

Wind gusts will drop off during the overnight hours, with winds 

maintaining a southwesterly direction. Breezy southwesterly winds 

will pick back up on Saturday morning. VFR conditions will persist

through the TAF period with no operationally significant cloud 

cover. Temperatures will climb over 100 degrees again Friday 19Z 

through 03Z, with a high temperature around 106 degrees. 



For the rest of southern Nevada, northwest Arizona and southeast

California...For the 12Z Forecast Package...Winds will remain 

relatively light, following typical diurnal directional patterns 

through later this morning when breezy southerly to southwesterly 

winds will pick up. These breezy southerly winds will continue 

into the evening hours, before dropping off overnight. The 

exception will be the western Mojave Desert, including KDAG, where

winds will favor a more westerly direction this afternoon and 

evening. VFR conditions will persist through the TAF period with 

no operationally significant cloud cover.

.FIRE WEATHER...Widespread southwest winds between 15 and 25 mph 

expected on Saturday, with gusts near 35 mph. Afternoon relative 

humidities will range between 5 and 10 percent, with up to 15 

percent in the higher elevations of southern Nevada and northwestern 

Arizona. Combined with critical fuels, a Fire Weather Watch has been 

issued for Arizona Zones 101 and 102 and Nevada Zones 461, 462, 465, 

and 466 on Saturday... with the Arizona Zones persisting into 

Sunday. Near to critical fire weather conditions will likely persist 

into the middle part of next week as this trough pattern remains set 

up over the Desert Southwest with a continuation of gusty winds and 

low humidity.
