Aviation

For Harry Reid...For the 12Z Forecast Package...Light winds gradually veer to the east by mid-morning, increasing to around 8KT. By early to mid-afternoon, winds shift to the southeast, increasing to 10-15KT with gusts to around 20-25KT expected thereafter through sunset. Winds become light and somewhat variable overnight, increasing out of the southwest toward the end of the forecast period. Clouds will be SCT-BKN around 8-12kft through the forecast period, with some improvement expected this afternoon. While thunderstorm activity largely remains outside of the Las Vegas Valley, impacts to approaches can be expected due to scattered to numerous thunderstorms across the Mormon Mesa and Peach Springs Corridors this afternoon onward.

For the rest of southern Nevada, northwest Arizona and southeast California...For the 12Z Forecast Package...Winds around 5-10KT this morning will shift to the south and southeast by late morning into early afternoon and become elevated, with gusts to 20-30KT common through sunset. Isolated showers this morning will give way to more widespread shower and thunderstorm development by this afternoon, especially across the southern Great Basin, northwestern Arizona, and portions of southeastern California. Convection is largely expected to stay out of the vicinity of area terminals, with the exception of KBIH, where at least vicinity showers and thunderstorms are expected through the forecast period. The best window for thunderstorm impacts at KBIH will be between around 21/20Z-22/02Z, with erratic gusty winds, lightning strikes, and ceiling/visibility reductions due to rainfall expected. Cloud bases will generally be at or above 10kft, but will be as low as 6-8kft in the vicinity of convection.
