Increasing chance for isolated severe storms for parts of the Tennessee and Ohio Valley on Saturday.
A surge of warm and humid air will be building out ahead of a cold front moving out of the Central Rockies. There should be a narrow region of 60° dew points for the cold front to work with, but there will be several factors working against the chance of severe weather. There will likely be some early morning showers and storms ongoing before the cold front arrives. This will likely weekend all the available potential energy for severe storms. Also, there will likely be a good amount of prefrontal cloud cover that will help keep the atmosphere relatively stable. There should at least be a very isolated chance that a storm could turn severe by Saturday afternoon.
Severe Weather Outlook (Saturday)
The Storm Prediction Center (SPC) has placed a “Marginal” risk of severe weather over parts of Arkansas, Kansas, Tennessee, Kentucky, Missouri, Indiana, Illinois and Ohio for Saturday. This means the isolated risk of severe storms with low duration and coverage area. Winds of 40-60 mph will be possible to go along with hail up to 1″ in diameter.
Severe Weather Threats
The main weather threats will likely be brief heavy rain and wind gusts up to 60 mph. The large hail and tornado threat should be low with this particular set-up, but not completely ruled out of the forecast.
