Forecast updated 4:30pm EST - 14 Oct 2011
The big story for next week is an invasion of cold air in the middle of the week. After a pleasent but breezy weekend, a strong low develops in the north that begins to extend southward. Strong cold air advection associated with this system moves cold air over the Great Plains region beginning on Monday night/Tuesday morning (as shown below)
The trough associated with the low pressure system strengthens even more over the week, drawing a "tongue" of cold air that stretches across the US even down into Texas where they will experience cooler than average temperatures. Here in Indiana, temperatures will reach highs in the mid-50s.
This system will dominate the region for much of the week next week with the low pressure and cooler air exiting the area next Friday.
