Thank you so much for the replies. I totally agree with your statement that it is better to be over-prepared than being blindsided by the unpredictable weather on Whitney. And I was not at all frustrated, just unsure of how to prepare for the upcoming trip to the mountain due to the variation in weather forecasts.

It makes sense due to its location and other circumstances, that there are many variables which would come into play when making these forecasts. I was just a bit shocked that the variations itself would swing wildly from one prediction to another. Time will tell of course and I will be patiently waiting until the day approaches.
