A nice batch of showers and thunderstorms are rolling across the area as I type this update...much needed rain as parts of western KY & northwest TN are in moderate drought conditions.
The cold front and associated area of low pressure responsible for bringing today's showers and storms will press on to the east tonight, and most of the precipitation should be out of the area shortly after midnight.
The big story with this system will be the drastically cooler air that pushes in as a big dome of Canadian high pressure takes over in the wake of the front.
You'll notice a big difference in temperatures as early as tomorrow morning, when lows could drop into the upper 40's across portions of southern IL & southeast MO, if skies can clear out quickly. Tomorrow afternoon, temperatures will struggle to reach 70 with a blustery north wind expected. Then tomorrow night, it's not out of the question that a few spots could flirt with record lows, as temperatures fall into the mid 40's. The record for Thursday night/Friday morning at Paducah is 44 degrees.
By Sunday, the center of high pressure will drift east into New England...
With the return flow, winds from the south will pump some warmer air back into the region for the end of the weekend and first of next week. This will also bring moisture back into the region, possibly setting us up for some scattered showers and thunderstorms by the first of the week. More on that in the next few days.
