Strong winds will be developing later today
Gusty southwest winds around 15 to 30 mph are expected to develop by this afternoon, creating hazardous boating conditions. Afternoon temperatures are forecast to reach into the upper 60s under mostly sunny skies today. Lows tonight will be rather mild due to a combination of clouds and wind, with readings projected in the mid 30s to lower 40s around the Basin.
An unseasonably cold, upper low and frontal system dropping south from the Gulf of Alaska will bring increasing clouds and winds on Thursday as it moves into Northern California. Southwest winds 20 to 30 mph with gusts to 45 mph are forecast at Lake level with gusts over 80 mph along the Sierra crest Thursday afternoon.
High temperatures on Thursday will cool into the mid 50s to lower 60s while much cooler air arrives on Friday behind the front lowering daytime temperatures into upper 30s to mid 40s.
Temperatures Friday will be around 20 degrees below the seasonal normal of 63 for this time of year. A mixture of rain and snow is expected with the front Thursday evening changing quickly to snow overnight.
Computer forecast models are indicating light precipitation with this system; however, we could see several inches of snow in the upper elevations with an inch or two at Lake level by Friday morning.
Temperatures will be slow to warm on Saturday after a chilly start to the morning. Low temperatures are forecast in the teens and lower 20s Saturday morning with afternoon readings struggling to reach the lower 50s under a cool northerly flow.
Highs temperatures warm back into the 60s on Sunday as higher pressure aloft rebuilds back into the area with sunny skies and light winds.
