Residents of eastern Inyo County, northeastern Clark County, and southern/central Mohave County awoke this morning to the chill of the first freeze of the season, with the National Weather Service in Las Vegas issuing Freeze Warnings effective through 8am PST. Temperatures dipped as low as 34 degrees in areas including Shoshone, Tecopa, Mesquite, Moapa, and Kingman, marking a frigid start to the day. The NWS Las Vegas advises that the cool trend is set to continue, owing to a persistent northwest flow aloft expected to bring sporadic north winds and a drop in mercury throughout the week.
As we look ahead, the forecast isn't just about grabbing extra blankets; travel and outdoor activities might get complicated. Midweek promises to rustle up some change with an inside slider-type system moving into the southern Great Basin and Mojave Desert, heralding increased northerly winds that could blow from 15 to 25 mph. In the wind-swept valleys, particularly those running north-south, you might even see gusts punching up between 25 and 35 mph on Wednesday and Thursday.
Those pining for warmer weather, however, have something to look forward to as the week progresses. By Friday, temperatures are expected to climb, reaching values that the NWS described as "above-normal." So, while we may be starting off with a bit of a cold snap, the desert is set to warm up. In the meantime, residents and visitors alike should be wise to prepare for windier and cooler conditions, especially when out and about.
For pilots or anyone taking to the skies, the NWS aviation forecast for Harry Reid International Airport calls for light winds following typical daily patterns with some variability this morning. By mid-morning tomorrow, winds are expected to shift to the northwest and increase to around 10 KT, with a chance of higher gusts beyond that period. VFR conditions will prevail, accompanied by increasing mid- and high-level clouds between 15–25 kft today, tapering off into the night. Lastly, the NWS hasn't forgotten about its army of citizen weather observers, prompting spotters to report any significant weather happenings or impacts as usual.
