Kentucky Hydrologic and Agricultural Drought Status:

Date: Monday  Jul 17  2018
Re: Palmer Drought (PDSI)/Crop Moisture (CMI) Indices
Above Normal Temperatures and Below Normal Rainfall:

The second week straight in July with dry conditions was unlike the very wet 
first-half of the year for the Bluegrass State. Several counties in the west did 
a little bit better on the rain than the remainder of the state pushing the 
western climate division above normal for rainfall. The west also had more of 
the heat than the remainder of the state but a couple of slightly cooler days 
occurred at mid-week. Yet, the trend of warmer than normal temperatures
continued for the week and for the past 11 weeks.

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: Topsoil Moisture Short, Germination Slow
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: Topsoil Moisture Short, Germination Slow

Rainfall needed above normal to end the hydrological drought: West  2.67 inches, 
Central  0.00 inches, Bluegrass  0.00 inches and East  3.32 inches.

...Severe Weather Expected Today, Heat Advisory West...

According to the latest weather forecasts, an outbreak of severe weather is likely this afternoon and evening across Kentucky. The Storm Prediction Center has a large portion of our area in a "Moderate Risk" (level 4 out of 5 severe risk). Damaging winds, very large hail (> 2+ inches in some instances), and a few tornadoes are possible.

An unseasonably strong storm system will move into the lower Great Lakes through this evening, with a surface cold front trailing from this system also approaching our region by later this evening. The strong storm system will interact with a strongly unstable airmass to develop numerous strong to severe storms. Large hail, damaging winds, and a few tornadoes are all possible along with excessive lightning and heavy rainfall. The most widespread period of storms will be from late this afternoon through late evening. The storms should be out of the area midnight. Scattered showers and storms are then possible mainly each afternoon and evening through the weekend, although aren't expected to be as strong as today.

In addition to the potential for severe weather, western sections of the state also have a Heat Advisory in effect. The heat will be the main threat for today with southern portions of the region exceeding triple digit heat index values. Livestock Heat Stress will rise into the Emergency Category in the west and Danger Category for the remainder of the state.
