...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE
MID-MISSISSIPPI VALLEY...
...SUMMARY...
Thunderstorms, capable of damaging winds and hail, are expected this
afternoon through the early evening across parts of the
Mid-Mississippi Valley.
...Synopsis...
A strong upper-level trough will amplify across the northern Plains
today. At the surface a strong cold front will extend from the
western Great Lakes to the Ozarks Wednesday morning and from the
eastern Great Lakes to the mid-South by Thursday morning. Strong to
severe storms are possible along and ahead of this front this
afternoon into the early overnight hours from the Ohio Valley to the
mid-South.
...Mid-Mississippi Valley...
The airmass will be very dry to start the day across the
Mid-Mississippi Valley, but surface dewpoints will increase rapidly
through the morning as low-level flow strengthens and brings 60s
dewpoints northward. This will result in increasing instability by
mid-afternoon as temperatures increase into the 80s south of the
decaying overnight convection across the Lower Ohio Valley. A few
supercells may develop on the southern end of this decaying activity
during the afternoon. Low-level flow will be relatively weak ( CHECK UPDATE ZOOM GRAPHIC
