Rain for Montgomery???

Please refer to the Richmond thread. Long-range forecasts are consistently, demonstrably WRONG. There's a simple scientific reason why it is an impossible task, but I won't bore you right now. Anything past a 5-day forecast is professional malpractice.

For what it's worth...I live 2hrs away and it has rained off and on every day for a 3 weeks....and it's showing nothing less than 60% all week except for saturday shows no rain...

I really hope it clears up and the rainman moves away..

The weekend prior to the Piedmont Pro-Am, forecasts showed 90% all weekend long and racers were going crazy, wondering when they were going to reschedule it, etc, etc. The long-range forecast was complete garbage, and we had an absolutely beautiful, picture-perfect weekend.

I have been tracking long-range forecasts AND how they change for a couple of years now. I save a screenshot each day, and they will change by more than 15 degrees and +/- 60%. It's chaos theory. It is not physically possible to make accurate long-range predictions due to the number of variables involved, and if any one initial constraint is off by the tiniest nano-anything, that error compounds exponentially over time.

Tuesday prior to a race weekend is the earliest that you will get even a decent look at the forecast... and even those are frequently wrong. I've even seen them wrong in real time, which is truly stunning... Save yourself the stress.

These are actual pictures from actual forecasts:

I must admit it looks real gloomy at the moment, I wouldn't pack the fridge yet.
