August in July

Significantly cooler air is pouring into the East Coast - much needed relief from the heat and humidity. Well, the humidity will still be up there today thanks to showers and thunderstorms associated with the front.

Severe thunderstorms will be a problems across the Plains this afternoon and tonight. There is a threat of large hail and damaging wind, as well as a small threat of tornadoes. The storms won't be well organized, but the greatest threat of severe is in the area bounded by the red.

Cold air coming through Canada early next week will drop snow levels across the Canadian Rockies down to 8000 feet... pretty low for mid-July.

This continues to look like a very long August weather pattern... which will probably last well into August.
