Area Forecast Discussion National Weather Service Las Vegas NV Issued by National Weather Service Flagstaff AZ 1031 AM PDT Wed May 21 2025

SYNOPSIS
Warm and dry conditions are expected through the week with many desert locations creeping towards triple digits.
Afternoon breezes will increase Thursday and Friday as a weather system moves through to our north but dry conditions will continue. Warm and dry weather will persist into early next week.

UPDATE
A warming trend will continue today with temperatures peaking on Thursday. A dry weather system is forecast to deliver a bit of cooling along with gusty southwest winds starting Thursday. The best chance for minor wind impacts remains across our western deserts on Thursday and Friday. Any cooling with this system will be on Friday and Saturday. Breezes subside over the weekend and into next week while temperatures begin to climb starting Sunday. Dry conditions prevail as precipitation chances remain below 10%.

SHORT TERM
Today through Friday night.

Low amplitude ridge will keep our region warm and dry through the near term with mostly clear skies. A weak shortwave will push through to our north on Thursday and Friday, and mainly work to enhance regional wind speeds. This boost of wind may also help deepen our mixing and allow temperatures to eclipse 100 degrees for the first time this year at Las Vegas. Overall, wind speeds look a bit below thresholds for advisory products, but a patch work of wind advisories may be needed if wind trends increase slightly, mainly across the western Mojave Desert.

LONG TERM
Saturday through Tuesday.

Ensemble guidance has our late-week system pushing out of our forecast area Saturday morning, leaving us with lingering breezes and slightly cooler temperatures. However, forecast highs on Saturday are still a 2-5 degrees above normal for the time of year.
Positive 500mb height anomalies quickly return on Sunday and will likely persist into next week as a ridge develops over the western US. This would drive temperatures up a few more degrees while also keeping breezes light and conditions dry. However, some guidance (mainly the GFS/GEFS) hints at a cutoff low sneaking underneath this ridge next week. Should this occur, we could see more seasonal temperatures due to cloud cover and lower 500mb heights. Some convection is even possible if the low were to track through the CWA Right now, the former solution (ridge and above- normal temps) appears to be the more likely solution (70% chance), but trends will have to be monitored over the coming days.
