.DISCUSSION...through Tuesday. Quiet weather over the next 24 hours as high pressure brings generally clear skies, light winds, and near normal temperatures. We will start to see some minor changes Thursday as a closed low off the Pacific Northwest coast begins to dig south along the west coast. This will bring an increasing southwest flow to the region and better mixing which will allow high temperatures to rise a few degrees Thursday afternoon. We will also see some increasing surface winds across central Nye County, but overall there really won`t be any significant changes from today. The closed low will continue to dig south Friday and as this occurs, we will start to see increasing southwest winds with most areas seeing breezy to locally windy conditions, especially in our locally favored southwest wind belt stretching from San Bernardino through Clark, Lincoln, and Mohave counties. Wind gusts between 25-35 mph will be fairly common in these areas, but the threat of wind gusts over 40 mph is only around 10-20%. Wind advisories are not expected at this time. Another concern will be for fire weather, but at this time all zones expect the Lake Mead and lower Colorado River Valley are below critical fuel status and winds down the river are not expected to reach criteria. Precipitation chances are largely confined to the Sierra and Great Basin where NBM PoPs are 25-50%. With snow levels around 9,500-10,000 feet, the Sierra crest will likely (60% chance) see 1- 4" of snow with this system. Elsewhere, where precipitation falls, it will be in the form of light-to-moderate rain, but that is mainly regulated to the higher terrain of Esmeralda County.
Beyond Friday, the main low will shift east leaving just a general trough pattern across the west. This will keep temperatures a few degrees below normal through into early next week along with mainly dry conditions. &&
