Area Forecast Discussion National Weather Service Las Vegas NV 310 PM PDT Mon Apr 3 2017 .SYNOPSIS...Isolated thunderstorms will continue in the Colorado River Valley and Mohave County through early evening before dissipating. It will be mostly clear but breezy at times elsewhere. Dry, warm weather is expected through Thursday when the next system approaches bringing in windy conditions and the next chances of showers late this week. && .SHORT TERM...through Tuesday night. Potent upper level shortwave, associated cold front blew through the Las Vegas Valley between 100 and 230 pm unleashing locally heavy rain, small hail and wind gusts up to 50 mph. Broken line of showers and thunderstorms currently extends from Searchlight northeast to Colorado City. The line will continue to slide southeast through the lower Colorado River Valley and Mohave County before dissipating or moving out of Mohave County all together around 8 pm MST. North breezes (15-25 mph) will linger down the Colorado River Valley on Tuesday. Elsewhere, temperatures will be near normal Tuesday with lighter winds outside of the river valley. .LONG TERM...Wednesday through Monday. Expect quiet weather with slightly above normal temperatures Wednesday under ridging aloft, giving way to increasing southwest flow on Thursday as the ridge moves away to the east. The stronger flow will bring breezes and warmer temperatures, with Thursday likely to be the warmest day of the week before the next storm begins to affect the region. Precip chances should begin Thursday night in the Sierra and spread across the southern Great Basin Friday night and the Mojave Desert Saturday as the mean trough axis moves through. Temperatures will come down a little on Friday and more on Saturday due to the greater cloud cover and precip chances. Windy conditions will also be possible Friday and Saturday. Dry weather looks likely for most if not all of the area on Sunday, then the models diverge wildly on Monday, with the differences related to whether or not to amplify a shortwave trough coming in from the Pacific. Left the forecast for Monday alone, and will let the next shift reassess model trends. && .AVIATION...For McCarran...Improving ceilings late this afternoon as line of thunderstorms along cold front moves into Mohave County. Peach Spring corridor will be impacted by thunderstorms through 8 pm MST this evening.
