Stepping outside this morning you would think it was July or August.  Unseasonably warm conditions are coupling with dew points in the middle to upper 60s to help create quite the muggy feel to the central Indiana air mass once again.  This will help fuel showers and heavy rain producing thunderstorms today, especially during the PM.  Perhaps the most widespread rain and thunderstorms will arrive Wednesday into early Thursday as a wave of low pressure moves up along a cold front that will be just east of our region by that time frame.  We still forecast locally heavy rainfall amounts during the course of the next 48 hours, including widespread additional 1.25″-1.50″ totals.  The other big story will be the dramatically cooler temperatures that filter in tomorrow.  We’ve called Wednesday our transition day and that remains our idea now, as well.  Temperatures will likely fall through the afternoon and evening hours.  Speaking of cool, temperatures will remain in the 40s for the better part of your Thursday (hope you haven’t put those jackets and sweaters away just yet)!  We’ll slowly begin to shake the showers and clouds over the weekend and have trended more optimistic for Sunday’s forecast into early next week.

Most widespread shower and thunderstorm activity will likely occur Wednesday into early Thursday.
