Sun thru Monday – A short-lived ridge is shifting eastward as a weak system passes through the northwest Sunday. This will bring increased winds and high-level clouds to the region, but precipitation should be limited to near the Oregon border, with meager totals. Sunday, surface gradient is stronger but less of a speed/gust spread. Monday, as the jet moves over the eastern Sierra wind speeds will increase with surface wind gusts of 30 to 45 mph and ridge gusts of 80 to 90 mph likely. Highs Sunday will return to near Normal, a few degrees cooler Monday
Tuesday - The trajectory of the jet stream and main area of low pressure is well to the north and are fairly progressive but lacking organization this far south, so precipitation totals should be minimal. Generally, Mono County totals of up to a few hundredths are likely for some locations. Temps a few degrees cooler than normal.
Wednesday thru … - The large scale pattern next week will feature a trough developing in the Great Basin and over the Rockies with ridging building into the southeastern Pacific. The pattern will become more amplified through the week as additional shortwaves dig into the Great Basin deepening the trough into the Southern Rockies. Wednesday and Thursday will remain cool with lingering showers possible Wednesday. Wednesday and Thursday could also be quite breezy as cold fronts push through from the northwest. Daytime high temperatures will remain below average through most of the week with highs in the upper 40`s to low 50`s in the Sierra. The storm track continues to stay active in the Pacific Northwest next weekend which will keep the ridge from amplifying over the western U.S. Currently looks like next weekend could be similar to this weekend with above average temperatures limited to just a few days. Precipitation is looking unlikely next weekend, however, the ridge is showing signs of retrograding west which could allow fast moving cold fronts from the north back into the region by the first week of May.
