Winter Storm Possible Monday Night into Tuesday?
Low pressure is forecast to develop over the Oklahoma and Texas panhandle region Monday afternoon into Monday evening. This low
pressure is forecast to intensify as it tracks east-northeast across the Ohio Valley region and eventually into eastern Great Lakes by
Wednesday morning. Southerly winds in advance of the storm system will draw moisture from the Gulf of Mexico northward into the
developing low pressure system. As the storm intensifies, the moisture will interact with the cold airmass already in place across
the Great Plains and Midwest, setting the stage for the first potential significant winter storm of the season.
There are some early indications that a significant winter storm could develop and potentially affect all or portions of northern
Illinois or northern Indiana with significant snow or ice Monday night into Tuesday. Many variables need to come into play for a
significant winter storm to develop, and if just one is missing, the potential for a major winter storm decreases substantially. In
addition, only a small change in the forecast track of the storm will make the difference between significant snow, ice, or mostly
rain for northern Illinois and Indiana.
While confidence in the exact track and intensity of the storm is low at this time, persons living in or planning travel across the
Midwest Monday Night into Tuesday should closely monitor later forecasts regarding the potential for adverse winter weather.
