It felt more like late March than mid-May across the Midwest and the interior mid-Atlantic on Sunday and Monday as cold Canadian air penetrated the United States once again this spring.
This cold snap began early on Saturday afternoon when a cold front pushed through the Great Lakes. Cold air filtered in behind this front and was accompanied by rain and snow showers that lasted into Sunday morning across Michigan and Wisconsin.
While temperatures fell to below 40 as far south as Arkansas and as far east as New York, snow through Sunday morning accumulated up to 5.5 inches in Sault Ste Marie, Mich.
These cold temperatures pushed eastward on Mother's Day with highs in the Ohio Valley running 15 degrees below normal. High temperatures ran as cold as 10 degrees below normal around this area from Minnesota through Mississippi and up into Pennsylvania.
With a mainly clear sky and low winds on Sunday night, record lows were set from Illinois to Tennessee and into Virginia with another night of sub-40 temperatures.
This record-challenging cold continued through Monday with the coldest air being centered over central Pennsylvania and southwestern New York.
With temperatures forecast to dip to or below freezing both on Monday and Monday night, farmers and homeowners were forced to take extra precautions to ensure that their plants do not get harmed from the freezing temperatures.
The good news is that relief from these unseasonably cold temperatures is on the way.
A warm front will lift through the Midwest today allowing hot air from the southern Plains to move into the region. Temperatures will rebound to around normal across the Ohio Valley and above normal west of Indiana.
With this front taking aim at the Northeast on Wednesday, the cold temperatures will be forced to retreat into New England.
