Area Forecast Discussion National Weather Service Las Vegas NV 1259 PM PDT Fri May 17 2024
SYNOPSIS
Temperatures will peak today followed by a cooling trend over the weekend. Most areas remain dry aside from isolated showers over the Sierra and southern Great Basin over the next few days.
Gusty winds develop on Sunday and Monday afternoon as well, especially in San Bernardino County. Dry, seasonably warm, and breezy conditions are anticipated later next week.
SHORT TERM
Saturday through Monday.
Forecast challenges in the short term include warm but decreasing temperatures, gusty winds, and precipitation potential. The upper level ridge currently over the forecast area will progress east, replaced by a series of shortwaves and eventually a broad trough. As a result, a gradual cooling trend is expected with near normal temperatures on track to return by Monday. For Las Vegas, this means highs in the low to mid 90s over the weekend and upper 80s early next week.
The position of the incoming trough and associated low level jet will allow for increased southwesterly winds across much of the forecast area, with the strongest winds in western San Bernardino County. Saturday's gusts should be in the 20 to 30 mph range.
However, the NBM gives a 70 to 90 percent chance of wind gusts over 40 mph on Sunday and Monday in that area. Some uncertainty remains in the duration of the winds, will continue to monitor trends to determine the need for headline issuance.
The trough will assist in advecting moderate moisture into the forecast area, sending PWATs into the .3 to .6 inch range. The highest POPs are on Saturday over the Sierra and southern Great Basin due to a combination of increased orographic lift and atmospheric moisture content. However, coverage will remain isolated and precipitation totals should be light. Thunder cannot be ruled out with these storms.
LONG TERM
Tuesday through Thursday.
As the trough quickly moves east on Tuesday, ensembles showing another low digging south down the British Columbia coast. This system will maintain a broad longwave trough over the west through the remainder of the week. There is some uncertainty just how far south the low may dig, but as of now GEFS and EPS keep the lowest heights over the northern Rockies Wednesday and Thursday. Under this trough, the region will be breezy to windy with near to slightly below normal temperatures.
AVIATION
For Harry Reid...South southeast winds should shift to south southwest with gusts around 20 knots this afternoon. Gusts should end after sunset and then kick back up again around midday Saturday. No operationally significant clouds or weather expected.
For the rest of southern Nevada, northwest Arizona and southeast California...Winds will be generally southwesterly over most of the region this afternoon, with gusts ending around sunset except in the Barstow area where gusty westerly winds will persist overnight.
Southwesterly winds will increase again during the day Saturday, with the strongest gusts of around 30 knots in the Barstow area.
Chances for showers and thunderstorms this afternoon should be limited to areas from the Sierra crest to near Dyer, with coverage Saturday afternoon expanding from the Sierra crest eastward to the panhandle of Lincoln County.
SPOTTER INFORMATION STATEMENT
Spotters are encouraged to report any significant weather or impacts according to standard operating procedures.
