An atmospheric river will bring gusty to high winds, moderate to heavy rainfall, and potential flooding to California today through Saturday.

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.
