We head off to Central Indiana today, which is just outside the main dome of stifling heat sitting over the Central US, but are still feeling the effects of it themselves. How long will it stick around? Let’s take a look, shall we?
At 1153pm EDT, the temperature at Anderson, IN was 77 degrees under fair skies. A Heat Advisory is in effect from midday Friday through Saturday evening as heat indices look to push into the low 100’s over the weekend. The main dome of intense heat continues to sit over the Central Plains into the Mid-MS Valley, causing storms to ride up and over the top of the ridge, then plummets south-southeastward over the Upper Midwest and into the OH Valley. Activity shifting through WI/IL/IN currently continues its southward push until it peters out later this morning. Also keeping things active over the Southern Great Lakes is the tail end of a boundary lingering in the region from a low that’s pushed north of New England. That boundary will be less of an influence as we move into Saturday, but will be kicking off storms that will shift through the area during the afternoon/early evening hours. Saturday has the threat still lingering during the day, but odds are activity will focus both to the northwest and to the south. Humidity will be a bear both days, pushing expected heat indices into the 100-105 degree range. A good idea… just stay inside with the air conditioning and catch up on some DVR.

A line of potent thunderstorms is pushing its way through far northwestern Indiana, trailing back over Central Illinois and all the way up over far northeastern Iowa. It could make it down to central IN before the morning comes.
