Sun weather coverage
After a weekend of scattered showers, lots of sunshine, hot temperatures and some afternoon gusts are heading back to the Las Vegas Valley, according to the National Weather Service.
A southwest flow will lead to dry conditions through Wednesday with temperatures running a few degrees above normal, the weather service said.
High temperatures today will range from around 98 degrees on the west side of the valley to around 109 degrees on the east side, forecasters said. Winds will be from the southwest 10 to 20 mph through the valley, they said.
High pressure will again develop over eastern Arizona during the second half of the week, allowing monsoon moisture to move northwest for an increasing chance of thunderstorms, forecasters said.
