May 1: Sunshine and Flooding

Starting off May with summer-like weather.  It started off chilly with a low of 48°, but it soared this afternoon to almost 10 degrees above average with a high of 84°. Great day for skipping rocks.

Tonight will be much milder then last night, with lows around 60.

You’ll feel an increase in humidity tomorrow. High temperatures tomorrow will be similar to today’s — in the low-mid 80s. Expect even more of the same on Thursday as the southerly wind pushes in lots of warm moist air.

Widely scattered showers and thunderstorms are expected Friday. I don’t anticipate them to be severe.  Here’s initial timing with Futurecast. It will remain warm.

Showers will linger into early Saturday, it will still be warm with highs in the upper 70s.

Sunday and Monday will be mostly if not entirely dry. Temperatures over the weekend will still be above average for early May.

This weather and forecast is such a contrast to this date 8 years ago when  torrential rains and catastrophic flooding hit Middle Tennessee May 1-3, 2010.  The storm killed 18 people in Middle Tennessee and at least 27 in all of Tennessee and Kentucky.  Property damage estimates totaled into the billions of dollars and prompting a Presidential Disaster Declaration for many counties in West and Middle Tennessee.  To make things even worse the mid state had several rounds of severe thunderstorms, which caused wind damage and tornadoes.

Several records were set during that three day period.

  • In Nashville, a new 24-hour rainfall record was established when 9.09 inches of rain fell on May 1st and May 2nd
  • A new two day rainfall record was established when 13.57 inches fell on May 1st and May 2nd
  • A new calendar day rainfall record was set when 7.25 inches of rain fell on May 2nd. It was also the rainiest day in history.
  • The Cumberland River was at an all time high since the dam system was established.

That’s an event I hope we never repeat. I’ll have an update on tonight’s weather on News4 at 10pm.
