Why was the tornado warning issued late Sunday night across Onondaga County?

Storm Team Headlines

Many in Onondaga County were rudely awakened late Sunday night a little after 1230 Sunday night/early Monday morning to buzzing alarms on their phones that there was a Tornado Warning! The warning prompted you to seek shelter immediately and go to the basement or lowest floor of your home as soon as possible!

Yes, there was a lot of lightning and heavy rain and even a little hail in spots too, but not much damage occurred thankfully with this line of storms as it rolled through between 11 and 3 am Sunday night/early Monday morning.

Was there a tornado anywhere in Onondaga County, or CNY, late Sunday night? At this point, with such minimal damage reported across Onondaga County and CNY it appears there was NOT a twister late Sunday night thankfully.

So why was the warning issued by the National Weather Service then? This is because the velocity scan of the storm displayed the movement of the rain towards (green colors) and away (red colors) from the radar site within the thunderstorm that was moving through Syracuse. When we as meteorologists see the red and green coloring right next to each other on the velocity scan that tells us there’s rotation taking place within that cell. Due to the rotation detected on the doppler radar velocity scan the National Weather Service decided to issue the Tornado Warning.

Below is a tweet from the National Weather Service in Binghamton showcasing the velocity scan that triggered the Tornado Warning late Sunday night.

Thankfully, this tornado warned storm likely only had rotation up in the clouds and not down at the surface in the form of a tornado. It was stated live on television that just because a tornado warning was issued doesn’t mean there is a tornado on the ground unless it is observed/spotted which thankfully was not the case.

HERE’S AN EXAMPLE OF WHAT LIKELY HAPPENED OVER SYRACUSE LATE SUNDAY NIGHT

Either way, when a tornado warning is issued in your area you want to make sure you get to the lowest floor in your home and away from windows, preferably the center of your home. Hopefully it’s a long while before we have to worry about this again!
