I am hoping some of the local experts can let us know which weather forecasts you look at? We'll be making our first attempt at Mt. Whitney in 11 days!
First, I'd also like to say the posts on the Current Conditions part of this forum are really useful, especially regarding how much (or little) snow is left on the trail. Then I look at the various weather forecasts, especially the ones listed as resources on this forum. But I noticed some pretty big differences between the forecasts. For example:
- mountain-forecast.com predicts a high at the summit of 48F for the next several days, dropping to a high of 46 or 45 at the summit the end of this coming week.
- timberlinetrails.com predicts a high at the summit of 55F, then dropping to a high of 52F by mid-week.
- the NWS (gold standard?) predicts a more balmy 61F at the summit today but dropping to a high of 56F by he end of the week.
I can understand the NWS being slightly warmer (but it seems like a big difference), if I'm correct that it doesn't really target the summit. I believe its a point forecast that covers the small green square shown on its website and it even mentions an elevation of 13,110'. I sometimes wish we could just chop ~1,400' off the top of this hike.
Of course, all forecasts are just a guess but can any one explain the differences - especially between the first two forecasts? Anyone with experience as to which one is usually more accurate? Or do you have a different forecast that you like better?
Also, I'm worried about the heat in Lone Pine and even Whitney Portal the days before our hike sapping our strength. We plan to spend much of Sunday acclimating at Horseshoe Meadow where it should be nice and cool but then we'll have to go back down to the heat. And plan to spend the day before just relaxing at Whitney Portal. If anyone has other suggestions I'd love to hear them.
I've searched this forum and didn't see any discussion of the various forecasts. Apologies if I missed it in another thread.
