This link takes you to the NWS , about a week ago NWS split the forecast for the eastern Sierra North and South.
I see a lot of reference to other weather sites but recall the NWS maybe the source for many of the other reports
If you want a forecast for the different elevations or locations look to the lower right and you will see a green box on a topo map image... move the cursor left and click... this will give you a report of that elevation . Search for a report 13 miles w/o Lone Pine and you will see elevation of 13,000' for example with a new report.
Next if you want hourly forecast rain, snow, wind temperature wind chill and more look to the right side of the report and click on hourly then scrool down to read the hourly forecast plus each item will have other reporting.
I like the NWS discussion for the macro over view
Also always check time of report and date range
.
The NWS hints that reports are about 80% correct and out about 3 days and can change quickly so always check hours before not days before you head into the mountains.
A note of caution we suggest that the temperature and wind reports are very close , moisture snow/rain and time are very hard to forecast , That puts the pressure on the hikers to watch and make decisions based on what you see. That is why I am not a fan of early starts before day light you could be walking into a storm at the upper elevation miles to get down to a safe zone.
A quick question do you think it rains /snows every day at noon in the Whitney area? Recall we are located near the southern end of the Sierra when reports of snow / rain in the Sierra always check what part of the Sierra and notice the annual moisture range for the Lone Pine area is about 3-4 inches of moisture a year Tahoe has 36-38 inches Mammoth 20-24 inches a year.
When/ what to watch our wild card seasons are the monsoonal storms so we tend to watch the Arizona weather , this hints of a system that may create moisture in our area.
