Skies ran mostly sunny across the Bluegrass State and along with southerly flow 
in place, highs jumped into the upper 70s to middle 80s each day. Rain held off until 
the weekend for most of the state (some light showers across far W-KY on Friday). 
Coverage turned widespread at times, most notably on Sunday with some pockets of 
moderate to heavy rainfall. Overall, the state averaged 0.93 inches for the week, 
most of which fell on Sunday. This number marked a third straight week that the state 
average has ran above normal. 

WEST KY Long-term Hydrological Moisture status is: NEAR NORMAL
CENTRAL KY Long-term Hydrological Moisture status is: NEAR NORMAL
BLUEGRASS KY Long-term Hydrological Moisture status is: NEAR NORMAL
EAST KY Long-term Hydrological Moisture status is: NEAR NORMAL

WEST KY Crop Moisture status is: Favorable For Normal Growth And Fieldwork
CENTRAL KY Crop Moisture status is: Favorable For Normal Growth And Fieldwork
BLUEGRASS KY Crop Moisture status is: Favorable For Normal Growth And Fieldwork
EAST KY Crop Moisture status is: Favorable For Normal Growth And Fieldwork

Severe storms possible this evening/overnight

Storms are ramping up late this afternoon as a cold front approaches the area. A Severe Thunderstorm Watch has been issued for mainly the Purchase area of Western KY, but others could be added as the evening progresses. Stay weather aware! The main threat is damaging winds, but an isolated tornado and/or large hail cannot be ruled out.

This frontal boundary will exit the area by tomorrow morning, leaving behind a dry weekend ahead. Saying that, temperatures will take an abrupt downward trend with highs limited to the 60s for both Saturday and Sunday. Some in the upper 50s. Sunday morning lows will likely dip into the low to middle 40s for most, but cannot rule out some low lying and sheltered locations making it into the upper 30s. Suppose a patchy frost cannot be ruled out for these locations.

Looking farther out, our next shot of rain looks to hold off until midweek.
