Near century old Halloween rain records may fall
A few spots may break a 94 year old Halloween record this year. It appears Halloween 2013 will be remembered as a soggy one with potential record Halloween rainfall forecasted.
While the Autumn season is typically our wettest across Northern Michigan, weather records at several Northern Michigan locations that go back decades and in some cases back to the late 1800's show that most locations have never had more than an inch of rain in a 24 hour period at Halloween. The only place that has of our five main climate sites is Sault Ste. Marie which picked up a quick 1.24" back on Halloween of 1974.
Gaylord has come close, with 0.97" falling in the old rain bucket 94 years ago on Halloween 1919. In fact, on that same day both Houghton Lake (0.88" and Traverse City (0.60") had their biggest one day Halloween rains. Those records have stood the test of time for the past 94 years. On a sidenote, Alpena's biggest Halloween rain is just over a half inch at 0.54" in 1932.
Some of these long standing records may indeed fall Thursday as a moisture rich/strengthening storm system will arrive. Rain will break out later Wednesday night and remain steady through Halloween into Thursday night over all of Northern Michigan. Here are some of the old records and the 7&4 Storm Team's forecasted rain amounts.
Sault Ste. Marie- Old Halloween Record Rainfall: 1.24" set 1974
Forecasted Rainfall: 1.51"
Gaylord- Old Halloween Record Rainfall: 0.97" set 1919
Forecasted Rainfall: 0.70"
Alpena- Old Halloween Record Rainfall: 0.54" set 1932

Forecasted Rainfall: 0.96"
Houghton Lake- Old Halloween Record Rainfall: 0.88" set 1919

Based on our forecast, Sault Ste. Marie and Traverse City should break the record Halloween rainfall with the others coming close. Steady rain will end Thursday night with lingering rain showers remaining in the forecast through Saturday.
