(KPLR) – A slow moving Low Pressure system is swirling across the area with tropical humidity, clouds, and isolated thunder-showers. Do not be surprised if a "cold air" funnel forms in a few of those thundershowers, as the cold air from aloft sinks with the rain, and the warm air from areas the sunshine has broken through and heated the surface, along with the induced spin from the "Low," conditions are favorable for funnel formation.
Cold air funnels are generally weak tornadoes, but can still do minor/isolated damage. Rain chances diminish as the sun sets in the early evening. Highs today near 77 and lows near 63 Tuesday night. The focus of rain shifts into Illinois on Wednesday.
