Las Vegas started Monday, April 6, under clear skies, with temperatures near 63°F at Harry Reid International Airport and light northwest winds. The air is very dry, so mornings feel crisp while afternoons warm up quickly.
That warm-up will be the big story through the workweek. Highs are expected to reach about 86°F on Monday, climb to around 90°F on Tuesday, and land near 91°F on Wednesday, with overnight lows holding in the upper 50s to low 60s. A weak disturbance is forecast to pull moisture northeast from southeast Arizona, creating a limited chance of afternoon storms in eastern Mohave County on Monday, according to the National Weather Service Las Vegas.
Spotty Afternoon Storms Eye Eastern Mohave
The incoming moisture plume is unusually robust for April, running roughly 200-250% of normal. Most of the stronger instability stays to the east, so any thunderstorms that form should be hit-or-miss rather than widespread. Where storms do pop up, the main concerns will be gusty outflow winds and dry lightning. Most valley neighborhoods are expected to stay dry, but communities in eastern Mohave County and along the river should keep an eye on radar this afternoon.
Cutoff Low Late Week: Cooler Temps, Shot at Showers
Later this week, a cutoff low is expected to move in from late Thursday into the weekend, bringing cooler temperatures and a better chance for showers by Friday and Saturday (April 10–11). The National Weather Service notes that precipitation probabilities on Saturday are running around 20-50%, depending on the exact track of the low, and a few thunderstorms cannot be ruled out if the system passes overhead. Winds could turn breezy with the change, especially across desert and river areas. As outlined by the National Weather Service Las Vegas, plan for cooler afternoons and a chance of wet weather late in the week…
