Area Forecast Discussion

KEY MESSAGES

* Breezy south-southwesterly wind gusts will continue through the week with dry conditions and near-normal temperatures.

DISCUSSION

Persistent troughing across the Western US will keep the region in a generally dry and breezy pattern through much of the upcoming week. In the near term, a trough will eject into the Northern Plains today before additional troughing drops south along the Pacific Northwest Coast by midweek. This will keep the Mojave Desert and southern Great Basin region in a southwesterly flow aloft, favoring breezy conditions in the afternoons and any lingering monsoonal moisture focused more across central and eastern Arizona. A few isolated thunderstorms may develop across eastern Mohave County through midweek, but coverage is expected to be quite limited.

Otherwise, thanks to the pattern at hand, temperatures will remain near seasonal normals through the period. The flow pattern will trend more zonal by the weekend allowing for the gusty winds to ease while temperatures remain near normal.

AVIATION...For Harry Reid...For the 06Z Forecast Package

Light southwest winds tonight give way to breezy south-southeast winds Tuesday morning and afternoon. Some uncertainty exists in the exact wind direction and magnitude during the morning hours (15z-19z). Think on average, winds during this time will be from ~160, but wouldn't be surprised to see periods as far east as 120. By mid- afternoon, expecting a gradual turn to a more true south direction. Gusts 15-25 knots likely (90%), with 30+ knots possible (25%). Winds should subside after sunset and remain from the south-southwest overnight. Mostly clear skies with just a few mid-level afternoon clouds. Temps peak just shy of 100F on Tuesday.

For the rest of southern Nevada, northwest Arizona and southeast California...For the 06Z Forecast Package...Breezy south winds linger tonight in areas southeast of I-15, but elsewhere light winds are expected. Southerly to southeasterly winds pick up across most of the region Tuesday morning and persist through sunset. Peak gusts of 15-30 knots are likely (90%). Isolated convection possible (10- 20%) across northwestern Arizona and eastern Lincoln County Tuesday afternoon/evening. Here, few to scattered clouds around 10kft are expected, but mostly clear skies farther west.
