Persistent heat across much of the central US and the Ohio Valley region is continuing into the weekend and beyond, unfortunately. This means a warm weekend for Bowling Green and a warm start to our work week next week. It appears a stubborn upper-level ridge is over the area and will remain over the next several days. A warm start to November appears likely with no help in the precipitation department either.
The below maps from the NAM show the ridge in place over the Ohio Valley region:

The resultant warm air mass can be seen below with temperatures well into the 80s across a good portion of the country by 4 PM CST.

The map below is our setup for Sunday and reveals a shortwave moving through the mid-level flow, but offers little drops in temperatures and no reasonable chances for rain.

Moving into Halloween and the beginning of next week remains warm. This notion can be seen in 500 hPa anomaly maps, courtesy of the GFS, seen below:

The anomalous heights help to represent geopotential heights values above climatic averages for a particular time of year and latitude. This, in short, helps to reveal where a warm air mass is in place underneath an upper-level ridge, or upper-level high. Troughs are often seen in the blue regions where colder air is in place.
Despite the warmth, it is usually confined to the afternoon hours, evening temps drop off quickly if skies are clear.
Overall, expect these conditions:
Saturday: Highs in low to mid 80s, clear skies. Lows in upper 50s and around 60.
Sunday: The same, increasing clouds possible in evening with shortwave passage.
Halloween Monday: The same, decreasing clouds.
Tuesday: The same.
Boring weather is okay though, right? Hopefully, however, pattern changes result in more expected temperatures, and bring some precipitation to our dry region.
Otherwise, have a great weekend!
