Our steamy and stormy pattern begins tomorrow with humidity rising for all, but storms will only impact some of us. A quasi-stationary front will be lined up along I-64 later in the day. That will in turn become the focus mechanism for thunderstorm development around 5-6 PM. Downpours and lightning are the two obvious threats. Updrafts will be strong enough to support hail cores, mostly 1" or less in diameter. Since the mid-level flow isn't strong, localized downburst winds can occur when a storm collapses. Bottom line, be on the look out for strong storms before sunset along and south of I-64. Storms simmer down after midnight as we lose heating... Â
If we get severe weather this week, Wednesday afternoon poses the greatest threat. There will be one weakening wave of storms in the morning, then a stronger wave develops during the afternoon. While all modes of severe weather are possible, this appears to be more of a damaging wind threat than a tornado threat. Either way, stay with WDRB for updates about severe potential and details for Thunder Over Louisville!Â
