Jim, if you wanted to scare the first time PP runners you have probably succeeded. But, it should be noted that in 2008 that the local news stations started warning about the cold front a week in advance. The weather forecasts for the PPA in 2008 were very accurate (30 deg temps, 30 mph winds, mixture of snow/sleet/rain). The much milder weather for the PPM the next day were also accurately predicted. The weather predictions for subsequent years (2009-12) have also been accurate.
I prefer the hour by hour forecasts because I am a slower runner. Typical PP weather (no fronts) starts with clear skies at sunrise with increasing cloudiness with showers/thunderstorms starting in the early afternoon. Wave 2 runners have a much better chance of getting caught in a storm. Most people who climb 14 teeners, try to be off the mountain by noon.
Jim is correct about planning ahead if you are an out of towner. In 2008 all of the stores (REI, Walmart) sold out of foul weather gear.
Here are the links for the hr-by hr weather forecasts for Manitou and PP. Best advice - check the weather and plan accordingly.
