Area Forecast Discussion National Weather Service Las Vegas NV 205 AM PST Thu Dec 7 2023
SYNOPSIS
A passing trough producing areas of gusty west winds today will be followed by north winds Friday and Saturday along with cooler temperature. High pressure building over the weekend will give way to another trough early next week but the probability is low for significant weather impacts in our region.
SHORT TERM
Today through Saturday.
Winds and cooler temperatures will be the most noticeable weather concerns today through Saturday though only minimal impacts are expected and no advisories are planned. The trough currently moving across the Nevada was producing localized terrain-enhanced gusts over 40 mph in the lee of the southern Sierra and Spring Mountains, but speeds will diminish this morning for most areas except the western Mojave Desert where west-northwest winds gusting 30-35 mph will occur between Barstow and Twentynine Palms late this morning through this afternoon. North winds with sustained speeds of 10-20 mph will develop tonight and Friday then persist through Saturday across much of the region as additional energy dives into the back side of the trough over eastern Nevada and Utah followed by an amplified eastern Pacific ridge building inland. The strongest winds will be along the lower Colorado River Valley with gusts 30-40 mph confined near Laughlin-Bullhead City as is typical in this type of pattern. High temperatures will fall a few degrees today then pull back and additional 4-6 degrees each day Friday and Saturday with readings only in the mid to upper 50s across the desert zones by Saturday.
LONG TERM
Sunday through next Thursday.
No significant weather is in the outlook for next week although the weather pattern remains somewhat progressive. The aforementioned ridge will flatten Sunday in response to a disturbance moving through the Pacific Northwest. The latest medium range ensembles are now indicating a trough being carved out over the western states Tuesday through Thursday, and some ensemble members indicate into a cut-off low could develop over southern Nevada/California Tuesday and Wednesday. However, moisture appears to be quite limited and the potential for any precipitation would be limited to Lincoln County northwest Arizona though the NBM probabilities are less than 10 percent so no chance of precipitation is mentioned in the forecast.
AVIATION
For Harry Reid...Breezy southerly winds continue through the early morning hours, with gusts of 15-20 knots possible at times. Around 14z-15z, winds lighten and turn northerly, with speeds less than 10 knots expected through the afternoon hours. Typical light southwest winds forecast to set in around 02z this evening, persisting through the night. SCT-BKN high clouds linger through most of the TAF period.
For the rest of southern Nevada, northwest Arizona and southeast California...Breezy south winds in the Las Vegas Valley through the early morning hours, turning northerly or going light and variable after 13-15z. Winds remain light through the afternoon and evening.
Northwest breezes at KBIH this morning, with stronger north winds developing this afternoon. Gusts of 20-25 knots expected. At KDAG, westerly winds persist through the TAF period, increasing during the daytime hours. Gusts 30-35 knots this afternoon, lingering through the evening. For sites in the Colorado River Valley, light and variable winds this morning, favoring a southerly direction in the afternoon with speeds around 8-12 knots. SCT-BKN high clouds linger through most of the TAF period.
