A busy weather day is in the making as strong to severe thunderstorms are forecast throughout the day and flooding concerns continue to rise.
Strong to severe thunderstorms will be possible throughout the day today. An initial threat may materialize in the afternoon hours. Scattered strong to severe thunderstorms may form between noon and 6 PM. These storms will form in an environment conducive to the formation of supercell thunderstorms. Isolated hail, damaging wind, and tornadoes are the main hazards with this wave. The tornado threat will ramp up some as low level winds become faster around sunset.
A secondary wave of severe weather is expected later overnight as the cold front moves through the region. A line of strong to severe storms is expected to develop along the cold front. This will lead to more of a damaging wind threat, though an isolated tornado will also be possible.
The Storm Prediction Center has outlined the region in an “enhanced” risk of severe weather. Think of this as a level 3 out of 5 threat. The Storm Prediction Center also notes the potential that a few strong tornadoes is possible, especially around sunset.
There’s also a “high” risk of flooding and flash flooding. Think if this as a level 4 out of 4 threat. Training thunderstorms throughout the day may lead to a “few” inches of rain. I’m currently thinking 2-4″ of rain may be possible this afternoon and overnight tonight. Remember to turn around when coming to flooded roadways. Flash flooding kills more people every year than tornadoes do.
A nicer day is expected Sunday, but we’ll get to that tomorrow. The main focus of today needs to remain on the severe weather and flooding potential. Be sure to have a way to receive severe weather warnings, and be ready to shelter in place in the event of a severe thunderstorm.
