First Glimpse of Fall

Today and tomorrow we will see temperatures and humidity increase as we continue to have southerly winds bringing us Gulf moisture. A low pressure system is positioned over the Northern plains and its corresponding cold front will impact our region Wednesday night into Thursday morning.

With this cold front, expect a squall line to develop over Missouri and Illinois Wednesday afternoon. The Storm Prediction Center has issued a Slight Risk for Illinois, Indiana, Ohio, parts of Missouri, and the northern tip of Kentucky on Wednesday.

By the time this squall line moves through western Kentucky into Bowling Green Wednesday night, the surface temperatures will have cooled and the storms will lose some of their strength. This is is the composite reflectivity forecast for Wednesday around 7pm:

These storms are expected to move through Bowling Green overnight on Wednesday and into the morning hours. These storms are not expected to be severe for our area, but heavy rainfall and lightning are likely.

Behind these storms is our first glimpse of Fall. The jet streams are entering their first phase of the season where they will merge and begin a very defined upper-level ridge/trough pattern that will bring warm-ups and cool-downs throughout the Fall season. The NAM 200 mb heights and wind shows the two jet streams as they are currently beginning to merge together.

After the front passes, a developing high pressure system will move across most of the U.S. for the remainder of the week. Temperatures will remain in the low to mid 70s for the latter part of the week into the weekend.
