Area Forecast Discussion National Weather Service Las Vegas NV 307 PM PST Fri Dec 8 2023

SYNOPSIS
North winds will increase today through Saturday and temperatures will cool several degrees behind a system passing over the Four Corners Region. Gusts around 40 mph will occur tonight and Saturday along and near the Colorado River Valley. High pressure building over the weekend will give way to another trough next week resulting in north breezes with temperatures near normal.

DISCUSSION
through next Friday.

A trough is currently digging south into the Four-Corners region.
Outside of breezy northerly winds, cooler seasonal temperatures, and periods of increased cloud cover, impacts will across the area today will remain minimal. Ridging will build in over the region tomorrow as the trough clears out of the Four-Corners region. This result in a tight north-south oriented pressure gradient at the surface, which will result in gusty northerly winds down the Colorado River Valley and across portions of eastern San Bernardino County. These winds will start ramping up after midnight, continuing through the morning hours before decreasing around mid-afternoon. In addition to tomorrow being windier, temperatures will be 2-5 degrees cooler than today's temperatures.

Temperatures will gradually rebound beginning on Sunday as the aforementioned ridge continues to push into the region. Dry and mild weather will accompany this ridge as it moves in early next week.
An inside slider will drop down the lee side of this ridge, moving into our area before becoming a cut-off low over the Desert Southwest around mid-week. Current guidance shows that this will be a relatively dry system, so precipitation impacts are not expected at this time. Cooler, more seasonal temperatures and breezy winds are the more likely impacts. However, current guidance suggests that temperature and wind impacts will be low to minimal.
