Kentucky Hydrologic and Agricultural Drought Status:


Date: Monday Jun 29 2020
Re: Palmer Drought (PDSI)/Crop Moisture (CMI) Indices

Below Normal Temperatures and Much Above Normal Rainfall:

Exceptional rainfall fell across the Bluegrass State over this past week as the state 
averaged 2.25 inches. This broke a four week stretch of below normal rainfall. While 
the state saw numerous rounds of showers and storms through the period, the most 
intense activity occurred over the weekend. Several waves of storms pushed through 
Kentucky and as the state sat within a very moist air mass, torrential rainfall was 
common. One of these waves led to substantial flooding across portions of West 
Central Kentucky on Sunday. The three highest accumulations according to the Kentucky 
Mesonet on Sunday came from Ohio, Muhlenberg, and McLean Counties with totals of 4 to 
6+ inches. This wave carried southeast into South Central Kentucky with numerous 
stations over two inches for the day.

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: UNUSUAL MOIST SPELL

WEST KY Crop Moisture status is: Moisture Adequate For Present Needs
CENTRAL KY Crop Moisture status is: Moisture Adequate For Present Needs
BLUEGRASS KY Crop Moisture status is: Moisture Adequate For Present Needs
EAST KY Crop Moisture status is: Prospects Improved But Rain Still Needed

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

...Heat & Humidity Into The Weekend With Storms Later Wednesday/Thursday...

Radar remains clear early this evening across the Bluegrass State with semi-comfortable temperatures in the middle to upper 80s. This changes tomorrow and through the rest of the week with high heat and daily storm chances in the forecast. Highs each day will hover in the upper 80s to low 90s. More moisture will make it feel more like around 100 at times during the heat of the afternoon. Hence, livestock heat stress will run in the danger to emergency category on a daily basis.

Producers should minimize moving livestock around the farmstead or transporting animals to the market during afternoon and early evening hours until animal heat stress decreases. Also provide animals plenty of cool water and shade. More info on mitigating heat stress can be found here. Do not forget about pets too!

Outlooks hint that this hot pattern will last through next week. While it will be hot, most days feature at least a chance for rainfall. Heavy rain, lightning, and occasional gusty winds will remain the main threats.
