Kentucky Climate Update
Date: Monday Mar 19 2018 Re: Palmer Drought (PDSI)/Crop Moisture (CMI) Indices Below Normal Temperatures and Precipitation: Even with spring right around the corner, Old Man Winter is making his presence known. The week started with a major winter storm in progress. A large portion of the state’s midsection received in upwards of 4 inches. The highest accumulations were saw around Lexington, Danville, and Richmond with 8 to 10 inches in spots. Unlike the snow events of 2015, Kentucky did not have Arctic air in place. In fact, temperatures rose above freezing into the upper 30s to low 40s on Monday. Saying that, the heavy/wet nature of the snow caused some trees to fall and corresponding power outages. Temperatures more typical of January continued through Wednesday with another round of wintry weather on Tuesday night. After a warm up to end the work week, more showers and even storms arrived for the first half of the weekend. Overall, the state averaged just over a half inch for the week, marking the third straight week of below normal precipitation for the state.

...Snow tapering off, but dropping into the 20s tonight...
Precipitation will wane this evening and overnight with clouds clearing. This will set up a cold night ahead with temperatures dropping into the 20s. Possibly some low to middle 20s where the greatest snow pack exists. UK Horticulture specialist point to plasticulture strawberry growers at the most risk as blooms are killed at 30 degrees F. With these forecast temperatures, plantings will need protected. More information on potential damage to winter wheat can be found here.
The bad news is the active pattern is not over as the next significant round arrives Friday night and into Saturday. This system could bring in upwards of 1 to 2 inches for much of Kentucky, in addition to some wintry weather mixed in. Stay tuned.
