.KEY MESSAGES...



* Breezy-to-gusty afternoons continue through the work week as 

  temperatures gradually climb back toward seasonal normals.



&&



.DISCUSSION...Today through Independence Day.



The western CONUS will remain situated beneath an upper-level trough 

through the work week. This pattern is conducive for shortwave 

troughs to move through the flow aloft, bringing with them breezy 

afternoons. In addition to breezy conditions, the region will remain 

quite dry, so those recreating outdoors with sparks or flames 

(charcoal grills, safe-and-sane fireworks, target practice) are 

encouraged to exercise caution and ensure there is a bucket of water 

nearby to prevent any fire starts. That said, there are slight 

chances (10-30 percent) of showers and thunderstorms in the eastern 

Sierra / northern Owens Valley this afternoon. Forecast HRRR 

soundings show a pronounced inverted-V, though, indicating there is 

substantial dry air at the surface. As a result, convection is 

unlikely to result in widespread wetting rain; fire starts due to 

dry lightning cannot be ruled out, as well as strong gusty winds 

from the direction of storms that form. Temperatures will gradually 

climb through the week, reaching near-normal readings by Friday. 

Late-week, ridging builds back over northern Mexico and the southern 

United States, allowing temperatures to climb above-normal for the 

holiday weekend.

.AVIATION...For Harry Reid...For the 18Z Forecast Package...Gusty

north to northwest winds will continue to subside this morning as

wind speeds generally fall to 10 knots or less. An occasional 

gust to 15-18 knots can't be ruled out through around 22z. Winds 

will shift to a northeast through east direction, becoming 

southeasterly between 20z and 23z. Winds will then shift to a 

westerly direction by 05z to 06z then settle to more southwesterly

overnight. Temperatures are expected to peak in the mid 90s this 

afternoon.





For the rest of southern Nevada, northwest Arizona and southeast

California...For the 18Z Forecast Package...Aside from KBIH and 

KDAG, where winds are following mostly diurnal patterns, northerly

winds persist this morning. This is especially true at KEED and 

KIFP, where gusty north winds have affected the Colorado River 

Valley. Winds will gradually work towards more diurnal patterns 

later today into tonight, however a few gusts of 20 to 30 knots 

will remain possible, especially at KBIH this afternoon, and 

KIFP/KEED. Additionally, a few showers and storms are expected to 

develop along the Sierra crest. This may eventually affect KBIH, 

where VCSH has been added to the 18z TAF. Any showers will product

gusty and erratic winds. From 00z on, a more diurnal wind pattern

is expected at all terminals with KDAG being the breezy outlier 

with gusty west winds overnight. Otherwise, winds look to remain 

in the 10-15 knot or less range.
