Storm chances arrive as Friday opens, Rain threat at times this weekend

DRIEST JULY IN 7 YEARS
Are you looking for some rain? This is the driest July in Indianapolis since 2011 (7 years). Only .47" officially for the city as rains this month remain selective.   Ranks as the 8th driest July on record.
MULTI-DAY RAIN THREAT
Could our dry July be taking a turn?  We do have some rain on the way as the jet stream takes on a rather out-of-season pattern.   An upper-level low drops in for the weekend brings sub-normal high temps and rain chances. No all-day rains but scattered storm threat starting Friday.
A warm front may bring the first of two round of storms to central Indiana starting around sunrise.  As the storm system nears, southwest winds will blow and temperatures will rise.  In between the storm the temperatures and humidity elevate to the 24th 90-degree day of 2018.
Many rain-free hours are coming Friday but a new batch of showers and storms will likely develop mid afternoon and during the peak heating of the day.  It will be early afternoon that a wind shift and dew point drop occurs triggering potentially another round of storms.
The Storm Prediction Center has outlined a portion of central Indiana for a risk of a severe storm or two.   Any stronger storms would likely contain damaging wind gusts and some hail.
While severe ingredients are not great, it looks like a few of the more gusty storms could occur near and around the morning warm front. We will monitor trends.
