Vegas residents and visitors, you might keep those light jackets at hand, at least for a few more days, before it's time to switch to T-shirts and sunscreen once again. According to the National Weather Service in Las Vegas, we're set for some "quiet weather" heading into the middle of next week, so don’t expect the weather to interfere with your plans, whatever they may be.

Currently, we’re experiencing seasonably cool temperatures due to a trough of low pressure moving through the area. But don’t get too comfortable — temperatures are expected to rise as a ridge of high pressure builds tomorrow. Conditions should return to near-normal by Tuesday and climb slightly above average through Thursday, with winds remaining light and following typical daily patterns.

Yet, the story doesn't end there; it twists, for as usual with our desert locale, the weather likes to keep us on our toes. By the week's end, we're expecting a return of monsoon moisture. This isn't your everyday drizzle, but potentially over an inch of precipitable water inching up as far north as Death Valley and the southern reaches of Lincoln County on Friday – that's a bit of wetness you might notice.

What this means is that, alongside the moisture, there's a chance for showers and thunderstorms to make a surprise cameo. Of course, there's uncertainty wrapped up in where significant cloud cover might camp out, limiting the potential for convection, especially at times the clouds decide to roll in on show," as stated in the National Weather Service forecast, keeping a tad bit of suspense alive.

Icarus-high fliers need not fret; VFR conditions prevail for Harry Reid and the remainder of southern Nevada, northwest Arizona, and southeast California. Winds, as per usual, will dance to the beat of their diurnal drums, and for the most part, except KDAG where some gusts may push the 10-20KT envelope in the evenings, everyone else can expect a breeze that won’t muss your hair.

So, whether you’ve got a stakeout at The Strip or an adventure beyond the city lights, keep your eyes peeled for updates. The National Weather Service encourages spotters to report any significant weather activity, but let’s hope the show is calm and the drama minimal.
