SYNOPSIS
Gusty south to southwest winds will occur over much of the region Thursday and Friday and linger into Saturday in Mohave County ahead of a large low pressure system moving down the West Coast. The system will bring widespread precipitation across our region Saturday, followed by showery weather Sunday and Monday and a drying and warming trend going into the middle of next week.
SHORT TERM
through tonight. Midnight satellite loop showed complex low pressure system spinning off the Washington coast and a jet streak coming through the Aleutians which will eventually cause this low to dig south into our area. Over our area, skies were partly cloudy. Surface obs showed increasing south to west winds and temperatures several degrees warmer than 24 hours ago thanks to the winds and clouds. As noted by previous shifts, the strongest winds were affecting the eastern slopes of the Sierra and into parts of the Owens Valley, as well as the higher elevations of the Spring Mountains. Winds will continue to increase in these areas and also spill down into the lower elevations as daytime heating leads to coupling. Thus, the Wind Advisories for this afternoon into tonight look good. Snow amounts in the Sierra are still likely to remain below Advisory criteria today, but the next system on Friday night and Saturday is worth watching. More on that one in the long term section.
LONG TERM
Friday through Tuesday.
The upper level pattern will begin to amplify Friday as a strong trough deepens off the West Coast. This trough is still poised to bring fairly widespread wet weather to the region over the weekend as the trough closes off and bottoms out off the coast of southern California. Precipitation will be on the increase in the Sierra as early as Friday afternoon and evening, with chances increasing and spreading east Saturday. As mentioned in the previous discussions, the best window for widespread precipitation accumulations is in the Saturday morning through Saturday night period as an impressive moisture plume is pulled up from the Eastern Pacific. Additionally, with snow levels hovering in the 6000 foot range, some locally heavy late season snow accumulations are looking probable in the Sierra and Spring Mountains, with NBM probabilities exceeding 70% for 8 inches of snow in the Lee and Kyle Canyon areas. With this in mind, hoisted a Winter Storm Watch for Saturday afternoon through Saturday night. While the main moisture plume will shift east Saturday, a broad upper low will remain overhead through Monday afternoon. The cold air aloft and lingering moisture will keep diurnally enhanced shower activity going into Monday evening. In addition to the widespread precipitation chances, temperatures will trend several degrees cooler than normal.
More stable conditions will begin to return Tuesday though there is uncertainty into how quickly the remnant upper level low moves eastward. As such, at least some low chances for showers will persist into Tuesday afternoon, especially across the higher terrain, along with continued cooler than normal temperatures.
AVIATION
For Harry Reid...Southwest breezes persist through the morning hours, ramping up after sunrise. The likelihood of 25+ knot gusts grows to over 50% by 15z and remains 50-90% through 06z tonight. Peak wind gusts up to 40 knots. Southwest breezes expected to weaken between 05z-10z, but remain elevated (10+ knots) through the night. Gusty conditions resume after daybreak on Friday. No impacts from cloud cover expected as bases remain aoa 15kft.
For the rest of southern Nevada, northwest Arizona and southeast California...Gusty southwest winds expected across the area today, with gusts generally in the 20-35 knot range, possibly up to 40 knots at KDAG and the Las Vegas Valley sites. Moderate to severe turbulence possible near and east of mountain peaks. At KBIH, vicinity showers linger through the morning hours, with a 10% chance of spilling over the Sierra and reaching the airport. Periods of CIGs down to 8kft possible during this time. For the rest of the area, dry conditions and cloud bases aoa 15kft.
