The high pressure responsible for the Arctic airmass currently in place across the area will shift east into the Appalachians today. At the same time a low pressure system is forecast to develop across the central and southern Plains states. Warm moist air from the Gulf will move northeast of this low and into our region tonight. Initially as the moisture moves in here…light snow should start to fall across south central Kentucky…with the snow progressing north this evening. As more warm air moves in above the surface…snow will become sleet and rain and then re-freeze as it hits the cold air nearer the surface. Snow…sleet and freezing rain will overspread our entire region tonight…with the heaviest precipitation ending by daybreak Thursday.

The high pressure responsible for the Arctic airmass currently in place across the area will shift east into the Appalachians on Wednesday. At the same time a low pressure system is forecast to develop across the central and southern Plains states. Warm moist air from the Gulf will move northeast of this low and into our region. Initially as the moisture moves in here…light snow should start to fall across south central Kentucky early Wednesday…with the snow progressing north through the day. As more warm air moves in above the surface…the ice will melt and then re-freeze as it hits the cold air nearer the surface. At this time, a changeover to sleet and then freezing rain is forecast to occur across south central Kentucky Wednesday afternoon. This transition zone will shift northward Wednesday night, reaching north central Kentucky and southern Indiana before daybreak Thursday and remaining there through the day as the low pressure moves near the Kentucky/Tennessee border.

The Geminid meteor shower, which peaks this year on Dec. 13th and 14th, is the most intense meteor shower of the year. It lasts for days, is rich in fireballs, and can be seen from almost any point on Earth.
Most meteor showers come from comets, which spew ample meteoroids for a night of ‘shooting stars.’ The Geminids are different. The parent is not a comet but a weird rocky object named 3200 Phaethon that sheds very little dusty debris—not nearly enough to explain the Geminids.
This makes the Geminids the 900-lb gorilla of meteor showers.
This month Earth will pass through the Geminid debris stream, producing as many as 120 meteors per hour over dark-sky sites. The best time to look is probably between local midnight and sunrise on Tuesday, Dec. 14th, when the Moon is low and the constellation Gemini is high overhead, spitting bright Geminids across a sparkling starry sky.
Bundle up, go outside, and savor the mystery.

At this time, a changeover to sleet and then freezing rain is forecast to occur across south central Kentucky Wednesday afternoon. This transition zone will shift northward Wednesday night, possibly reaching close to the I-64 corridor before daybreak Thursday and remaining there through the day as the low pressure moves just south of the state.
The exact track of the surface low is still uncertain. A more southern track would keep the warmest air south of the region, leaving our area with mostly snow. A more northerly track would bring more of a wintry mix into north central Kentucky and southern Indiana. Stay tuned for updates over the coming days on this developing winter storm system. Meanwhile, if you’re preparing your home for the winter weather, remember to check your roofing and gutter systems.
