Area Forecast Discussion National Weather Service Las Vegas NV 117 PM PDT Tue Jun 28 2022 .SYNOPSIS...Scattered showers and thunderstorms, a few possibly strong, are expected in the central and eastern Mojave Desert through Wednesday before a slow drying trend begins on Thursday. The most likely area for strong storms and heavy rain will be Mohave County. Slightly above average temperatures will continue across the region through Wednesday before slowly cooling off for the holiday weekend. && .SHORT TERM...through Wednesday night. Midday satellite loop showed cumulus clouds over much of the region, with thunderstorms popping over the higher terrain from Rachel to Mount Charleston to Mount Trumbull. The clouds were rotating clockwise around high pressure centered near the NV/UT/AZ triple point. Surface obs showed temperatures a few degrees above normal for late June, with dewpoints ranging from the mid 50s in the lower elevations well southeast of I-15 to the mid 30s farther west, farther north, and at higher elevations. The main concern for the rest of this evening through Wednesday will be thunderstorms. For the rest of this evening, the best instability is forecast in two areas - from Las Vegas east and south, where strong winds and heavy rain with slow- moving storms are both in play, and over the southern Great Basin from Esmeralda County eastward, where strong winds will be the main threat due to drier low level air. Wednesday gets a bit interesting as mid level low pressure moving along the Canadian border could generate just a bit of shear to go along with the thermodynamics, possibly leading to better organized, longer lived storms than what occurs today. The most favored areas look like along and east of a line from Rachel to Mount Charleston to Vidal Junction, although if storm outflows drag deeper moisture farther west any time between now and then, that could change. After peaking for most areas today, temperatures will start a slow downward trend Wednesday. .LONG TERM...Thursday through Independence Day. A noteworthy change in the weather pattern is coming up for the holiday weekend as a dry southwest flow begins to develop Thursday and Friday ahead of a broad eastern Pacific trough approaching the West Coast. This broad and somewhat anomalously deep trough is forecast to swing into northern and central California by Saturday then remain fairly stationary as it produces widespread breezy to windy afternoons with temperatures slightly below normal through Independence Day. This translates to high temperatures gradually decreasing to only top out around 97-102 degrees on Independence Day across most of the Mojave Desert sites except 105-107 in the Colorado River Valley. && .AVIATION...For Harry Reid...Wind gusts around 20 kts will generally favor a 150 to 210 wind direction this afternoon, though storms that form over the higher terrain of Clark County may kick off stronger gusty outflow winds from their direction. Otherwise, winds will become westerly after sunset before diminishing overnight. Gusty south-southwest winds return Wednesday afternoon with gusts of 20-25 kts. FEW-SCT aoa 12 kft through the TAF period. For the rest of southern Nevada, northwest Arizona and southeast California...South-southwest winds will continue this afternoon with gusts between 20 and 25 kts through sunset. Isolated thunderstorm formation in Mohave County and higher elevations of Clark County may result in gusty outflow winds from the direction of the storm impacting terminals at Las Vegas Valley and Colorado River Valley TAF sites with KHND being favored through 00Z. FEW-SCT aoa 12 kft through the TAF period. Thunderstorms on Wednesday will be favored over eastern Clark and Mohave County and south-south west wind gusts of 20 to 30 kts will be common. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && SHORT TERM...Morgan LONG TERM...Adair AVIATION...Czyzyk For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
