Growing Season Ends in Ohio Valley, Warm Lakes Means An Abundance of Lake Effect Snow
An End to the Growing Season Across the Ohio River Valley
The temperature dropped down to a shivery 26° in Bowling Green this morning leaving a frosty coating on the grass. This meant an end to the growing season for many areas across the Ohio River Valley.
Expecting another cold night across the region as a trough dips south and bring this cold Canadian air, all the way down to Central Alabama and Central Georgia.
As this cold air moves over the relatively warmer waters of the Great Lakes, lake effect snow develops and that is what has been occurring yesterday and this morning for Lake Erie and Lake Michigan.
By just looking at the water temperatures of Lake Michigan, it may be year in which we see an abundance of lake effect snow. Compared to last year, the water temperature is 5 degrees warmer. The warmer that water is, the more energy that is for generating snow when combined with that cold air from the north.
Next Big Storm?
No winter weather in sight over Glacier National Park this morning but this next system may by spreading up to 20 inches of snow into the Rockies across Montana by early next week. Winter storm watches are already in effect.
The southeast and the Ohio Valley remain cool while the Northwest will be above average for this time of the year.
