Date: Monday Mar 9 2020
Re: Palmer Drought (PDSI)/Crop Moisture (CMI) Indices

Above Normal Temperatures and Precipitation:

The work week started with mild and wet conditions in place. Widespread showers 
worked across the area Monday morning ahead of an upper level disturbance. After a 
short break that afternoon, another round moved through Kentucky that evening and 
overnight. This time though, numerous showers was accompanied by scattered storms. 
Some storms became strong to severe across Western and South-Central Kentucky, 
producing large hail and even a couple tornadoes. Overall, this accounted for the 
brunt of the rainfall for the week with the state averaging 1.28 inches. Saying that, 
portions of Western and South Central Kentucky saw more than two. The rest of the 
week stayed quiet with fluctuating temperatures, cooling off toward the end of the 
work week and warming up again over the weekend.

...Mostly Dry This Week, Except Increase Rain Chances Mostly South On Tuesday...

High temperatures have reached the low to middle 60s today. Low relative humidities combined with a breezy west wind has led to some fire weather conditions for portions of Eastern Kentucky, prompting a Red Flag Warning. Outdoor burning is not recommmended.

After a dry day, rain returns to the area late tonight and through the day tomorrow, ending west to east. This will likely be a light rainfall event with the highest accumulations expected across the southern half of the state with totals around a half inch or so. Decreasing farther north. The rain and cloud cover will keep temperatures much cooler on Tuesday with highs in the upper 40s to low 50s.

Looking ahead, dry weather returns through the end of the work week, along with a gradual warming trend.
