Boston Marathon Weather Forecast: Rain Again, But Better Than Last Year

BOSTON (CBS) - Getting a perfect weather day in April for the Boston Marathon is not easy. In fact, I'm sure that there are varying opinions among runners and spectators as to what a "perfect" day entails. This year will not be perfect. But, forecasts have been steadily improving over the last few days, and I think this year's running will be much more palatable than last.

If anything, runners may be complaining that it is TOO WARM, especially those starting later.

Temperatures will be MUCH milder than last year - check!

Winds will be out of the south and southwest, a cross/tailwind as opposed to a direct headwind least year - check!

The rainfall will be showery with breaks and periods of lighter rain, again, nothing like the drenching from last year - check!

So, naturally, when comparing to last year (one of the most miserable Boston Marathons ever run) there are many reasons to be thankful.

One last weather note - there is a small chance of an isolated thunderstorm during the race on Monday. Nothing organized or widespread, but at this point we cannot completely rule out a few rumbles of thunder.
