The big topic for this long range forecast is the low pressure system that moves eastward in the northern US, bringing drastic temperature changes and some small precipitation for the Midwest and New England regions. A cold front associated with the approaching low is expected to arrive in Indiana around late Thursday night (midnight). Low temperatures after the frontal passage return to below freezing, hovering between low to mid 20's.
After the front passes and the trough moves out of our area, we return to higher pressures but temperatures remain relatively cold. Winds exhibiting zonal flow.
