The gusty winds that we experienced today will weaken as we head into the overnight hours. A slight forcing mechanism from the approaching storm system could spark off a few showers across the region tonight. Temperatures throughout the area will be well above freezing heading into tomorrow morning with lows bottoming out around 40 degrees. Cold air advection will filter into the area following a weak cold front, keeping tomorrow’s high temperature into the middle 40s. Clouds will stick around throughout the day ahead of our next storm system.
Quick-hitting upper-level shortwave trough will swing through the Ohio River Valley Friday. The National Weather Service out of Louisville, KY issued a Winter Weather Advisory for Warren County as this system could bring the area a quick-hitting round of wintry weather.
High temperatures tomorrow drop off quick as cold air advection noses into the area dropping temperatures around the area to right around the freezing mark. If temperatures drop below freezing, that could lead to a quick changeover from rain to some sort of frozen precipitation. Model guidance hasn’t been consistent on the magnitude of cold air filtering into the region and when that changeover could happen. As we get closer to the event, model guidance should have a good grasp on the amounts of freezing precipitation. As of now, model guidance is spitting out a light glaze to possibly a .10 of an inch of ice.
The wintry precipitation will exit the region before the daylight hours on Saturday morning as high pressure builds to the north. Model guidance is indicating at high temperatures on Saturday staying in the middle 30s with partly sunny skies. Another shortwave will impact the region late Saturday night into Sunday bringing back the chance for light precipitation.
The entire area we continue to be in this active weather pattern heading into next week. For further updates visit the WKU Meteorology Blog and White Squirrel Weather.
