Our weekend weather will be greatly influenced by a storm system expected to intensify over the nation's midsection.
Warm air will continue to stream northward ahead of the developing cyclone, resulting in well above normal temperatures here and well up into the Ohio River valley and Mid-Atlantic region. Highs could reach the mid-70s here on Saturday and threaten the record of 75º in Columbus set in 1998.
Rain should hold off through Saturday, though we may see a few light showers well ahead of the main event which is expected to reach us Sunday. Severe storms will break out on Saturday in the lower Mississippi Valley, including damaging winds and possible tornadoes in the afternoon and nighttime. That batch of thunderstorm activity will charge eastward, affecting our area from Sunday morning through the afternoon hours, though weaker and less likely to produce any severe weather here.
As the low tracks rapidly north toward the Great Lakes and into Canada, the trailing front will slow, likely keeping some rain here through part of Monday. Drier air that moves in behind the cold front should bring sunshine and cool temperatures for Christmas Eve and Christmas Day.
Stay informed this weekend with the First Alert weather team for later information on the potential for any threatening weather on Sunday.
