It's been one hot week, but temperatures have been in a mostly normal range leading up to today, the first day of summer, according to the National Weather Service in Paducah.
In the weeks leading up to the official start of summer, both temperatures and rainfall have been above average, but not to an unusual extent. The high for June 19 in Paducah was 93 degrees, six degrees above average, but that is still considered typical for this time of year, a spokesperson said. This stands in contrast to an unusually cold winter.
"Since June 1, temperatures have been slightly above average. Prior to that, though, temperatures had been below average for the year, substantially below," said Dave Purdy of the National Weather Service in Paducah.
Purdy predicts temperatures and rainfall to be slightly above average for the rest of summer, but he emphasized that forecast periods extending beyond the next two weeks are not the most reliable.
For the upcoming week, high temperatures are expected to stay in the low 90s until Tuesday, when they will drop to or slightly below average in the high-to-mid-80s.
On average, the hottest days of summer come in early August with highs normally above 90 degrees. Typical highs for the start of summer are only slightly lower, averaging around 88 degrees on June 21.
Temperature norms are determined by averaging data collected in a 30-year period. Currently, they are based on data from 1980-2010.
