Examining “it’s a three out of five weather day tomorrow oh noes,” what it means and what it does not mean, alt. title: respirating into a paper bag

  1. WINDY. A storm line will arrive Wednesday night, but before that, south winds will howl 20-30 MPH and could gust over 40 MPH. Then when the storm line comes through those winds may briefly intensify and blow from the west/southwest so maybe yeah, tie down your things unless you want them in your neighbor’s yard.
  2. RANT ABOUT /OH NOES IT’S GONNA BE A THREE OUT OF FIVE/. You may have seen/heard breathless exclamations “it’s a THREE out of FIVE” threat based on the below SPC map. It is factually true on the SPC scale this is a 3 of 5 but that is like saying “the Titans are playing an NFL team tomorrow” and getting scared for no good reason — the Titans could be playing any NFL team. For example, Jacksonville (they suck, why worry because /checks notes/ they’re the Jaguars). Or, the Bengals (ruh roh, they are now featuring a competent offensive line and they franchise tagged their interception-making safety). Or, the Colts (whose QB carousel landed on 37 year old Matt Ryan so if the Titans were ever down 28-3 are we worried yet). The point is “three out of five” is like saying “an NFL team is coming to Nissan,” you don’t know whether to be concerned until you hear/read more about the opponent. (Note I considered using a Broadway play analogy but I am uncultured and would have made a mistake ranking the plays, although for sure The Scarlet Pimpernel would have been bottom).

3. TIMING. A squall line is going to come speeding through here probably early evening Wednesday night. “7-8 PM” is NWS-Nashville’s thought which seems about right to me (HRRR model agrees, below) tho that ETA could wiggle earlier or later than that, so look for an update (changes?) tonight and tomorrow. read more

Isolated Showers Later

Today will be a little bit chilly, and these temps are going to stick around through the weekend. Temps will be close to freezing overnight.

Later tonight, we might see some light showers in our area. Nothing widespread, and nothing severe, the clouds are just sprinkling a little. Timing is around 9 p.m., and it will clear out around midnight. read more

Rain, Maybe a Strong Storm Tonight

Lotta rain coming in. Some thunderstorms. Severe risk is low, but not zero.

HRRR model below shows showers and storms coming in this evening. Main line is over our area around 9:00 pm. Stay weather aware this afternoon through evening time. These showers and storms should be out of the area by early Wednesday morning with lingering sprinkles up until 12pm Wednesday. HRRR through 6:00 am tomorrow: read more

Heavy Rain Tuesday Night w/ a Flooding Risk

Another beautiful spring day today. Low 70s and sunshine. Clouds increase throughout today ahead of the system that is affecting us tomorrow.

Low pressure sweeps across the southeast tomorrow. Severe weather is not a concern for our area, that concern stays south of us (the legitimate severe thunderstorm and tornado concern will sweep from TX tonight to LA overnight into MS to AL Tuesday). For us nonsevere thunder, downpours, and gusty winds < 30 mph will be what we get. read more
