965 FXUS65 KREV 200936 AFDREV Area Forecast Discussion National Weather Service Reno NV 236 AM PDT Sat Oct 20 2018 .SYNOPSIS... A mild pattern with above average afternoon temperatures will continue through next week for northeast California and western Nevada. A weak low pressure system moving across the region may bring light showers to far eastern Churchill and Pershing Counties Sunday and Monday. Late next week, low pressure moving into the Pacific Northwest may bring some increase in winds and clouds. && .SHORT TERM... Northeast California and western Nevada remain between a broad upper low over southern California and an upper ridge centered over Oregon and Idaho. Easterly flow aloft and thermal gradients between the Great Basin and western Sierra slopes are inducing gusty easterly winds to between 40-60 mph along the Sierra crest. In addition, Lake Tahoe is experiencing winds between 10 and 20 mph, especially for the eastern side of the lake near/north of Spooner Summit. Winds should slacken this afternoon as the gradient between the ridge and trough weakens. Except for the elevated winds over ridges and for Lake Tahoe this morning, weather conditions today should remain similar to recent days with a mild afternoon, generally light winds, and clear skies. For Sunday and Monday, the ridge center will erode with the weak trough of low pressure over southern Nevada and California moving overhead. A wave moving around the eastern side of the trough will bring increasing mid and high level moisture over central and eastern NV. While that part of the state will have the the best chances for precipitation, a few light showers could form each day in far eastern Churchill and Pershing Counties. Elsewhere for northeast CA and western NV Sunday and Monday, little change in the weather is expected from the trough as forcing for precipitation is expected to be insufficient. -Snyder .LONG TERM...Tuesday through Friday... Ridge builds back into the California coast next week, pushing the storm track well into the Pacific Northwest. Models continue to trend farther north with the moisture coming into the West Coast, keeping northern CA/NV dry through next week. We have continued to lower POPs in the long term and removed all mentions of precip in our area as moisture will remain north in OR/WA. Temperatures will remain above normal for this time of year, with highs in the 70s across western Nevada and 60s in the Sierra valleys. -Hoon && .AVIATION... VFR conditions through the weekend with breezy ridge winds over the Sierra crest through this morning. Some weak mountain wave turbulence is possible this morning, although winds aloft will weaken by this afternoon. -Hoon && .REV Watches/Warnings/Advisories... NV...None. CA...None. && $$ For more information from the National Weather Service visit... http://weather.gov/reno |
