SYNOPSIS
Moderate north winds and a few degrees of cooling will occur today behind a low pressure system moving away toward the Rockies. A mean trough will hold over the western states this week into the holiday weekend resulting in near normal temperatures with elevated afternoon winds each day.
SHORT TERM
through Thursday.
Broad upper level trough will sit over the region through the next few days. No precipitation is expected through Wednesday night as dry west to northwest flow dominates the weather pattern. A wave embedded in the mean flow will dip down and pass through the region late Wednesday into Thursday. The main piece of energy will only brush the Southern Great Basin as it moves through central Nevada Thursday so no widespread impacts are expected with this system. The pressure gradient will tighten with the wave's passage so increasing south to southwest winds are expected Wednesday later afternoon and on Thursday. Probabilities for impact wind gusts over 40 MPH are little to none (<10%) across much of the region with the only hint of potential wind impacts being in the Western Mojave Desert where there is some low to moderate end (40%-50%) probabilities for wind guts over 40 MPH per the NBM ensembles runs. Other ensembles such as HRRR and ECMWF Ensemble show lowed probabilities or limit the higher probabilities to the higher terrain. Based on the overall synoptic set up, this scenario with the low winds would make more sense.
Expected isolated wind gust impacts such as crosswinds and patchy blowing dist at times Wednesday and Thursday late afternoons in central portions of San Bernardino County, including around Daggett, CA, where winds may gust up to 35 MPH at times...however widespread wind impacts are not expected.
Other than the winds, expect mostly sunny skies son Wednesday before some mid to upper level moisture works into the Southern Great Basin on Thursday with the main piece of energy. Further south, it will remain mostly sunny on Thursday. Temperatures Wednesday and Thursday will warm slightly compared to today's temperatures, with high temperatures expected to be right around normal for this time of the year.
LONG TERM
Friday through Monday.
Lower 500 mb heights and general "troughiness" will linger across the Desert Southwest through the weekend. Breezier afternoon winds will continue through Saturday as shortwaves embedded in the upper level flow continue to pass through the Great Basin. These lower 500 mb heights combined with a series of passing disturbances to our north will keep temperatures in the normal to slightly cooler than normal range as we head into the weekend.
Long term guidance is hinting at the 500 mb pattern becoming more zonal or potentially ridge-y Sunday onward. This would result in warming temperatures and the continuation of dry and relatively mild weather into early next week.
AVIATION
For Harry Reid...Breezy N/NE winds today, gradually weakening weakening in the afternoon and evening hours. Probability of 20+ knot gusts drops below 20% by ~20z this afternoon. Light NE winds turn to the W/NW tonight, with speeds remaining below 10 knots through tomorrow morning. S/SW breezes return tomorrow afternoon with a 60% chance of gusts over 20 knots. Clear skies.
For the rest of southern Nevada, northwest Arizona and southeast California...N/NE winds forecast at all the TAF sites this afternoon, with the strongest winds in the Colorado River Valley.
Speeds gradually weaken through the afternoon and evening hours, with most sites falling below 10 knots tonight. Most likely exception to this will be KDAG, where west winds around 10 knots persist through the night. Breezy W/SW winds return to the region tomorrow. VFR conditions and clear skies prevail.
SPOTTER INFORMATION STATEMENT
Spotters are encouraged to report any significant weather or impacts according to standard operating procedures.
