Waterspout – Sleeping Bear Dunes and moreAugust 14th, 2013 at 11:37 am by Bill Steffen under Bill's Blog, Weather
Click on the image to enlarge. This graphic from the Marquette NWS is a comparison of precipitation from Jan. to July for 2013 and 2012 over the Lower 48 States. It’s a pretty amazing reversal from the warm and dry conditions of 2012 over much of the Central and Eastern U.S. to the wet year we are having east of the Rockies this year. Agricultural conditions are better this year overall. So far in G.R. we’ve had 31.32″ of precipitation this year, compared to 21.50 for the same period last year. Average to date is 22.76″. So this year we are 8.56″ above average, last year we were much closer to average despite the dry early summer. Also check out the waterspout video from Sleeping Bear Dunes from Monday. Also, here’s a time lapse of Lake Erie freezing up last January. Speaking of freezing…it was an even-freezing 32 this morning at Doe Lake and Stonington in the U.P. Leota in Clare Co. plummeted to 33. It was 36 in Baldwin, 37 at Wellston (Manistee Co.), 38 at Leslie and Grayling and 39 at Manistee. The agricultural stations at Nunica and Lawrence dipped to 40, while Fremont, Ludington, Hart and Scottville all had low temperatures of 41. Other lows included 43 at Hudsonville, Belding, Hopkins and Big Rapids, 46 at Lansing, Jackson, Marshall, S. Haven and Hastings, 47 at Muskegon, Kalamazoo and Battle Creek, 48 in Holland and a relatively balmy 49 in G.R. The cumulus clouds have developed (note the lake-effect cloud band over Lake Michigan). Lake Michigan water temperatures tumbled yesterday evening (48 Muskegon, 53 Grand Haven, 55 Pentwater and Ludington, still 60 at Holland. The Accumulated Tropical Cyclone Index, a measure of the number and strength of tropical storms and hurricanes is very low this year so far. The current ACE value for the Northern Hemisphere is 169 compared to an average of 562 and all Northern Hemisphere areas are well below average. I do expect the tropical storm pattern to get stronger within the next 1-2 weeks. The Southern Hemisphere ACE Index is right at average for the year at 209. Great Lakes water temperatures are cooler than last year at this time and a little cooler than average.
