|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.
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%.
