Milder Temperatures Set to Return!

Bowling Green is in the final stretch of this arctic blast, which has brought cold to the region not seen in nearly 20 years. Much of Monday was spent near the 0-5° mark, flirting with the record books. This bitter freeze was brought about by the polar jet stream surging into the Midwest. Arctic air essentially moved downstream with the jet and collided with a flux of Gulf moisture on Sunday afternoon, bringing hefty snowfalls to the Corn Belt. The frigid temperatures were felt by a great deal of the East Central US, Bowling Green being no exception. Thankfully, relief is in sight. The howling winds which brought about dangerous wind chills are due to decrease. The Wind Chill Advisory for Warren County is set to expire at 9:00 AM CST this morning.
Forecast high temperatures across the East US today.

Temperatures will make a much better rebound effort today than yesterday. A low pressure system over the Hudson Bay will guide the polar jet on a retreating course to the north and east, resulting in zonal flow over south-central Kentucky. The Canadian air mass in place will be ushered along with it. While Tuesday will still be very cold, high temperatures will sit in the upper teens, perhaps reaching the 20s. A relaxed pressure gradient will result in lower wind speeds, hovering between 5-10 mph. However, this still means wind chills in the single digits today! Be sure to bundle up if you must be outside and leave exposed flesh to a minimum.

"Warmer" temperatures are just around the corner! High pressure is set to mature over the southern US tomorrow and skirt eastward. This will aid in advecting warmer air to our region, which will make for a nice return to more average conditions. Expect 30s for Wednesday and 40s by Thursday! A chance for rain and some morning flurries arrives on Thursday as well, but at this time, any snow or wintry mix looks to be minor.

Daily Forecasts:

Today: A high of 19° with winds from the south at 5-10 mph. Wind chill values below zero in the morning, then 0-5° by evening. Sunny skies.
Tonight: A few clouds with a low near 15°. South winds at 5-10 mph. Wind chill values from 5-10°.
Wednesday: A little warmer with a high around 37°. Winds from the south at 5-10 mph. Wind chill values between 5-10° in the morning.
Wednesday night: Clouds return. A low of 27° with light winds.
Thursday: Brief chance of snow/wintry mix during the morning hours (very minor accumulations) changing to rain before noon. Milder with a high of 44°. Chance of precipitation 30%.
