Another Round of Heavy Rain and Mountain Snow in California; Snow in the Great Lakes and Northeast

Another round of heavy rainfall will renew concerns for additional flash flooding and landslides in southern California around burn scars and coastal mountain ranges. A low pressure system is bringing enhanced snowfall downwind from the lower Great Lakes into the Northeast mountain ranges. Above average temperatures will challenge or break daily record high temperatures across the southern Plains. Read More >

While there have not been many records so far this month, the persistence of above-normal temperatures has translated to the warmest first half of May on record for Louisville, the second warmest for Lexington, and likely a top 5 finish for Bowling Green (depending on today's high and low, they could be third or fourth).

The next series of plots gives the temperature data so far this month, compared to normal and record values. Louisville just yesterday set a record high and warm low temperature, whereas Lexington also set a record high yesterday. Bowling Green has not set any daily record temperatures so far this month.

The above normal temperatures likely will continue through the 7-day forecast, but will depend on how much cloud cover we get with our higher rain chances through this work week. Looking beyond, the Climate Prediction Center's 8-14 day forecast continues to show a better chance for above-normal temperatures.
