A Real Reminder That Fall is Here

Weather Channel Graphic
Just in case you don't necessarily believe that Fall is here just wait! A series of cold front will allow progressively chillier air to arrive into the eastern half of the U.S. The first of these fronts is sliding through the Ohio and Mid-Mississippi River Valleys. It is rather weak and just will have a few showers associated with it and a brief day or so of cooling behind it.

The second and definitely stronger front will be making its entrance into the U.S. by  crossing the U.S./Canadian border Saturday into Sunday, in the Dakotas. It will progress southeastward through Sunday and by Monday morning, it will stretch from Green Bay, WI-Quad Cities (IA/IL)-St. Joseph, MO-Northern NM. Along the front some rain showers will be found but nothing severe. Behind the front, much cooler air will reside with temperatures falling into the low to mid 30s across much of eastern MT and throughout North Dakota. This will be the threat for FROST.



The front will rapidly speed further east and south Monday afternoon through Tuesday. By Tuesday evening, the front will stretch from Syracuse, NY-Washington, DC-Destin, FL-Corpus Christi, TX. This will allow the chilly and breezy conditions behind the front to affect the Great Lakes, Mid-Mississippi River Valley and Ohio Valley, Tuesday. This will then be the case for New England on Wednesday. Lesser affects will be felt further south from Texas to the Southeast but some cooling will be noticed.
6 to 10 Day Temperature Outlook from NOAA/NWS

The first significant wide spread FROST is possible from eastern Montana through North Dakota into northern Minnesota and Wisconsin, Monday/Tuesday, behind this front.

Yet a third front is expected to drop out of central Canada and into the Upper Midwest, Tuesday evening. By Thursday evening, the front will stretch from the eastern Great Lakes into western Ohio and back into southwest Missouri and then the Panhandles of Oklahoma and Texas.

The pattern looks to then hold on through next week with a definite feel of Autumn along and north of the Ohio River expected. -->
