I hope the weather forecast is wrong, but looking at AM showers with a high of 57 and cloudy on race day.  Chance of precipitation is 40%.   We've had really nice May weather here in the upper mid west and on the last day of the month in Norwalk it's there's a chance for rain and it will only be 57.  The day before, is calling for temps in the upper 70's but with a 60% chance of evening showers and partly sunny during the day.  The day after 70, with a 20% chance of rain and partly cloudy.  I hope they are wrong about Sunday.  I don't mind the cool weather, but cloudy and rain is not a good recipe for running the 1320.
