New 30 year normals

[Harry]

Managed to find Battle Creek 5nw. They show the new average at 58.1" which is surprising as they do have alot of blank spots ( missing data and thus see 01-02/05-06 etc ) in the data. YES Keep in mind they still add it all up regardless if there is missing data. The old average ( 1970-2001 ) they had was 53.1" and thus a decent increase despite the missing data.

Grand Rapids went from 70.2" up to 74.9"

Muskegon lost nearly 10" inches and they went from a average of 102.4" down to 93.7" OUCH..

Lansing went from 53.0" down to 51.1"

Ok so i was off with the new normal snowfall for here. Seems it is 60.6" per the now data section at GRR which just got updated today. So we went from 53.1 to 60.6" for a totals increase of 7.5"

Here is the Breakdown..

Oct, 0.6"

Nov, 5.0"

Dec, 16.9"

Jan, 16.8"

Feb, 13.0"

Mar, 6.3"

Apr, 2.1"

TOTAL, 60.6"

Bloomingdale gained and has a new average of 93.4".. Have to wonder if there is some 100+ areas just near/just north of there now?
