Kentucky Monthly Weather Summary

For the Period: December 2020 Near Normal Temperatures and Below Normal Precipitation: * Preliminary data from the UK Ag Weather Center shows the state averaged 3.13 inches for the month of December, which is over an inch below normal and marks a second straight month of below normal precipitation. Temperatures were up and down throughout December and ultimately ended near the monthly normal. December started with chilly temperatures in place and even some minor snow accumulations across Eastern Kentucky. Highs were limited to the 30s on the first day of the month, well below normal highs in the upper 40s to low 50s for that time of year. While temperatures did trend warmer over the next couple weeks, precipitation was still lacking. In fact, through the first half of December, the state had seen four straight weeks of below normal precipitation. In doing so, an area of 'Abnormally Dry' conditions was introduced across portions of South-Central Kentucky by the US Drought Monitor. Precipitation did increase over the second half of the month with multiple rounds of widespread coverage. One of the more memorable events was a strong cold front that pushed through Kentucky on Christmas Eve. After precipitation type started as rain, temperatures crashing behind the front transitioned any rain over to snow. Snow continued into the night and lingered into Christmas Day. The most significant accumulations were across Eastern Kentucky with 4 to 6 inches common, but some locations topped 8. Very chilly temperatures followed with morning lows on Christmas in the teens and highs on the day only rising into the upper teens to middle 20s. Much of Eastern Kentucky then saw lows in the single digits on the morning of the 26th. During this 48- hour window, wind chills dropped into the single digits and even below zero at times, pushing the livestock cold stress index into the emergency category.
