Locally heavy storms for some Wednesday evening

Showers and locally heavy storms will continue to dot the central Indiana landscape between now and midnight.  Admittedly it’s been feast or famine regarding storm coverage today, hence the “scattered” terming in the forecast.  For much of the afternoon the firing for storms has remained north of downtown Indianapolis and I-70.  But at the time of this posting rain-cooled outflow boundaries were noted heading southward into central Boone and Hamilton counties… and will likely become the triggering mechanism of new storm development within the next few hours.



So we can’t guarantee a dry night at The Mike for Indy Eleven’s match against Dayton.  Please note that umbrellas are not allowed in the stadium… only ponchos and other rain gear of that nature.  If you’re walking far to get into the Fieldhouse for Game 5 tonight you may want to pack an umbrella.  It may not be needed, but better safe than sorry with a 50-50 shot of showers and storms at this point.


Though most storms will stay well below severe criteria… torrential downpours, lightning are likely in anything that pops on radar.  Gusty wind and small hail are possible in stronger storms that can sustain updrafts… which has been difficult due to very little wind shear.


However, earlier this afternoon a landspout was captured in El Paso, Illinois.  Landspouts are typically weak/short-lived, hardly detectable on radar due to their development in low proximity to the ground (below the radar beam), and not accompanied by mid-level circulation (mesocyclone) from typical/stronger supercelluar storms.


Due to the slow-moving nature of these storms street flooding can occur under heavier cells.  Activity diminishes after midnight and the atmosphere will reload again Thursday.



After a muggy and mainly dry morning, showers and storms develop during daytime heating.  It appears the highest chance of storms will be along and south of I-70 along a weak cool front.  As this front passes to south, less humid air arrives just in time for the weekend.



Lows drop comfortably into the 50s Friday morning with mild highs the lower 80s Friday afternoon.  Sunshine fills the sky Saturday and Sunday as highs jump into the mid and upper 80s.


All long-range indicators point toward an active set up next week with several waves of storms and heavy rain potential.  Have a safe evening and keep an eye to the sky and Live Doppler 13.
