Wednesday Forecast
Good morning, everyone! After a cloudy, yet cool Tuesday, this pattern is expected to continue through our Wednesday and somewhat for our Thursday. For our Wednesday in Bowling Green, we will have a high of 69 F, and a low of 64 F later tonight. For the rest of the midsouth, the farther southwest that you go, temperatures will be warmer than they will in parts of eastern Tennessee, and northeastern Kentucky. General highs across the midsouth will range from 65 F – 75 F. This is due to NNW winds being driven by a large high-pressure center spinning across portions of Ontario, and Quebec, Canada bringing cooler, dryer air out of the Mid-Atlantic and New England regions. In terms of precipitation, eastern portions of Kentucky and Tennessee do have a chance to see some showers and thunderstorms today. These storms are being driven by an upper-level trough that is moving over the Midsouth. For the western halves of the states, we can expect mostly dry conditions. Cloud cover will also persist through most of the day today.
When talking about that trough, something to watch is going to be how this system evolves throughout the rest of the day today. As this trough moves through the split flow pattern across the eastern US, it is going to collide with the higher pressure across the central and southern plains. This is going to create a wind response that will amplify winds upstream of the trough axis and cause this trough to dig even farther south.
Thursday Forecast
For our Thursday, we will have a high of 78 F, and a low of 65 F. Temperatures are expected to rise following the passage of our amplifying trough. Temperatures across the western portions of Kentucky and Tennessee could even make a run for 80 F. Any precipitation chances would come from the leftover remnants of the trough as it moves on past our region. Even this, it would not be a lot and would affect mostly the eastern half of the region.
Weather Headlines
Spinning off the western coast of Mexico, Hurricane Polo became one of the strongest Pacific hurricanes on record in terms of pressure. Today, Polo reached a central pressure of 892 mb. For reference, the strongest Pacific hurricane on record is Hurricane Patricia in 2015, as its lowest pressure was 872 mb.
Fall lovers can rejoice, because even if it heats back up again, we have proof that fall still exists in our region. Have a great couple of days everyone!
