Temperature roller coaster to continue through next week
In the wake of the flooding rains that occurred last month, a topsy-turvy temperature pattern has become established across our region.
- A period of unseasonably cool temperatures occurred during the first week of May. There was even some patchy frost in parts of western Kentucky and southwest Indiana on May 4, when the low temperature was in the mid 30's. On May 5, the low of 39 degrees at Paducah set a new daily record, breaking the old record of 40 degrees set in 1957 and tied in 2005.
- A period of unseasonably warm temperatures quickly followed during the second week of May. At Paducah, the high temperature of 87 degrees on May 10 tied the record for the date, which was set in 1987.
- Unseasonably cool temperatures will continue for the next few days as a strong upper-level low stalls over the Ohio Valley. At Paducah, the coolest high temperature on record for Sunday the 15th is 59 degrees. The coolest high for Monday the 16th is 63 degrees. There is a good chance of breaking these records if thick cloudcover persists through the day. At Evansville, the records for these days are 55 and 57, respectively. The record lows for Tuesday, May 17 are 41 at both Paducah and Evansville.
- Temperatures will warm back up later in the week as humidity begins to return. Along with the warmth and humidity will come increasing chances of showers and thunderstorms.
When temperatures fluctuate so much during May, heavy rainfall typically accompanies the associated warm and cold fronts. However, rainfall has been relatively light since May 2, despite the large temperature variations. Climatologically speaking, May is the wettest month of the year and the peak of tornado season in our local area.
