We had two rounds of a couple pretty heavy showers and thunderstorms that crossed the region last night.  There was a few reports of limbs down across Franklin County.

There is a marginal (level one of five) risk for severe thunderstorms for this afternoon and evening south of a Carbondale to Evansville, IN line.

As far as precipitation for the next few hours, there is a line of storms that are stretching from Clinton County through Northern Marion County at this time.  They are drifting ESE.  If they stay together, they can bring some showers and possible rumbles of thunder to Franklin county.

Below is the Hazardous Weather Outlook and the seven day forecast for Franklin County.

Illinois, southwest Indiana, western Kentucky, and southeast

“All I-57 Northbound lanes are currently closed at milepost 44 ( just south of I-24) due to a crash involving three truck tractor / semi trailers.  It is anticipated that I-57 northbound will be closed for a significant amount of time for recovery and cleanup.  Northbound I-57 traffic is currently being diverted off of the interstate at Exit 30 (IL.

The National Weather service issued a special weather statement in regards to the heat this afternoon.  Heat indexes are to be between 100-105.

There is a marginal risk (level one of five) for severe weather for this afternoon into the overnight hours for Franklin County and most of Southern Illinois.  As you can see from the graphic to the left,  There are a few counties in Southern Illinois that are on the edge of a slight risk (level 2 of severe weather).

The Storm Prediction Center is in discussions of changing the term slight risk to an elevated risk.  Some meteorologists in this market already use that term.

This is what I expect.  The cloud cover should be lifting at any time.  In the late afternoon hours, you could see one or two pop up storms that could turn severe.

This is in advance of an approaching cold front.  There should be a line of storms that will move through the area from northwest to southeast.  The best time for them to reach Franklin County is between 10 and 11 p.m.  There is the possibility of one or two severe thunderstorm warnings being issued during this time.

The main threat is damaging winds, with large hail being secondary.  The tornado threat is near zero.

Please follow the website and especially the Facebook page for any watches or warnings.  Below is the Special Weather Statement involving the heat and the hazardous weather outlook.  At the end is the seven day forecast, which I will post daily from this point on.   The forecast will pinpoint on Franklin County.

If you are going north or west toward the St. Louis Metro area, there is a heat advisory for heat indices running from 105-110

NATIONAL WEATHER SERVICE PADUCAH KY

…Heat Index Values of 100 to 105 degrees expected today over
most of the area…

Another afternoon of oppressive heat and humidity can be expected
today, leading to heat index values between 100 and 105 degrees.

The highest heat index values will be over southeast Missouri and
southern Illinois where isolated location may briefly reach 105.
Values of 100 to 102 are possible over southwest Indiana and west
Kentucky.

A few showers and thunderstorms are expected today, especially
near I-64, which will help keep the heat down at a few locations.

Be watchful for those especially impacted by the heat. Young
children, the elderly, persons with serious health issues, and
pets are especially susceptible to the heat during this time of
year.

Do not leave young children or pets in cars with closed
windows…this could become deadly situation in a short period of
time.

Be sure to drink plenty of water, take frequent rest breaks in the
shade or air conditioned shelter. Get out of the heat, if you are
experiencing health issues.
