A very large ridge of high pressure over the Great Basin and the Southwestern US is still affecting our area, with temperatures projected in some areas of the Owens Valley today to reach 108 degrees. The valley floor at Yosemite recorded temps of 109 and El Portal 110 yesterday. Today should be the warmest day of the week with +2-3 degree increase over yesterday with record high temperatures a real possibility in many areas. Death Valley will see temps around 125 today. Slight cooling will happen on Friday.
Today for Bishop & the Owens Valley: Sunny skies. Daytime high temperatures around 108 and evening lows in the upper 50s. Light wind.
Friday for Bishop & the Owens Valley: Mostly clear. Daytime high temperatures around 104 and evening lows in the upper 50s. South wind 10 - 15 mph.
Today for Mammoth & the Mono Valleys: Mostly sunny becoming partly cloudy in the afternoon. Chance of isolated thunderstorm activity. High temperature range low 90s for the Main Lodge and around 102 for the Valleys. Low temperature range 53 - 63. West wind 10 - 15 mph.
Friday for Mammoth & the Mono Valleys: Mostly clear becoming partly cloudy in the afternoon. Slight chance of high based thunderstorm activity and dry lightning. High temperature range around 90 for the Main Lodge and 100 for the Valleys. Low temperature range 51 - 61. Southwest wind 10 - 15 mph.
The ridge will finally begin to weaken on Saturday in response to an upper level trough moving through the Pacific Northwest. Temps will be cooler through next week, but still above normal. Dry conditions will continue for the valleys, but there will be a possibility of isolated thunderstorm activity again over the High Country by midweek.
Grab your bear can or camp chair, kick your feet up and chew the fat about anything Sierra Nevada related that doesn't quite fit in any of the other forums. Within reason, (and the HST rules and guidelines) this is also an anything goes forum. Tell stories, discuss wilderness issues, music, or whatever else the High Sierra stirs up in your mind.
