...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.
