Today's Featured Analog...June 20, 2015

In the grips of a typical June heat wave, a pattern change looks to bring a period of wet weather to our gardens. In fact, it's possible that the rest of the month will feature above normal precipitation.

One of the top 15 analogs features one from June 20, 2015. Looking back at past storm reports and rainfall data, tropical moisture from the remnants of Bill resided over our region for a few days producing copious amounts of rainfall. Even severe weather was reported.

Over 4" rainfall accumulated over 7 consecutive days. Prior to this, the first half of June was typically dry, with less than 0.50" at Louisville. However, the second half of the month dealt a prolonged period of heavy rainfall and high winds at times. In addition to the 7-day stretch, there was also a 3-day period later in the month with over 2" reported at Louisville.

Therefore, over 6" fell during the second half of the month, falling just outside of Louisville's top ten wettest June's.

Remember, analogs only show a similar weather pattern that resembles the air mass and expected conditions presently. It does not mean we will see that exact type of weather. However, heavy rainfall over the next two weeks is very possible. Louisville has already recorded nearly 3" for the month. To achieve a top ten wettest June status, the monthly minimum amount needed is 7.01".

Although the WPC keeps the heaviest rainfall just north of the area, I would not be surprised to see some higher localized amounts across parts of our region due to the possible 'training' and slow movement of any storms.

We will see. Meanwhile, enjoy the respite from the heat especially tomorrow and Friday. Turn around and don't drown.
