The Storm Prediction Center has issued a Slight Risk of severe weather for areas along and north of the Ohio River in Kentucky and Indiana. Associated with this risk area are a 15% wind risk and a 5% hail risk. We're not looking for a big severe weather event here by any means, but some of the storms we'll see may have some damaging winds and possibly some hail. The tornado potential for today is just about non-existent here because winds throughout the different levels of the atmophere won't really be configured for it. We'll be keeping an eye on these storms as they develop late this afternoon into the evening.
Why the storms today? Two reasons: 1) A small upper-level disturbance will be moving through the region this afternoon/evening and 2) a cold front will be moving south into our area as we go through the day. These things coupled with temperatures in the mid 90's this afternoon and increased moisture will help to fire off some scattered strong storms. The good part about this cold front is that it will be ushering in some slightly drier air and a small, and I do mean small, lowering in temperature for Wednesday. That means we'll see highs a degree or two cooler tomorrow than today's 95-degree high and a heat index under 100.
The increasing presence of high pressure on Wednesday and Thursday with lower amounts of moisture in the air behind the cold front means we'll see rain chances disappear completely until we get into Friday. By then we'll be watching multiple upper-level disturbance that will be making a run for Kentuckiana. These disturbances will have the potential to bring us more rounds of storms through at least the beginning of next week.
