A problem I'm having with the new winter precip fetch option is that you have only two choices: a 72 hour forecast or a 24 hour forecast. The script uses the 72 hour but as I've applied it to my web site, it's confusing people because the previous images (which are still generated by my office, BOX) applied to single storms. Currently, we have two events in the 72 hour window, so a quick glance by a user at the map makes them think "that's a lot more snow than the forecast says!".
Conversely, the 24 hour map would under-report what is expected for a long-lasting storm.
So... just grumbling for right now but I may go back to grabbing the office-generated images so that the info presented is based on the current (or immediately upcoming) event.
