Regional Climate Summary for 2017

In taking a look back at 2017, the weather service office in Paducah reported that for the second straight year, “temperatures were well above normal across our region.”

Paducah tied 2016 for the third warmest year on record. Cape Girardeau tied for the seventh warmest year on record.

As for precipitation, a large portion of the region experienced drier than normal conditions last year.

However, some areas in Ozark Foothills of Missouri, the Pennyrile region of West Kentucky and along the Tennessee border in Kentucky experienced near to above normal precipitation.

In Missouri, this was largely due to excessive spring rainfall – before a drought set in later in the year. For Western Kentucky, the remnants of seveeral tropical systems played a big part.

Cape Girardeau had the fourth driest year on record last year.

During 2017, Paducah had the fourth warmest January on record, the warmest February on record and the warmest April on record.

Cape Girardeau had the fifth warmest January on record, the warmest and fourth driest February on record, the eighth warmest and fifth wettest April on record, the sixth driest July on record, the fourth coldest August on record and the sixth driest September on record.
