...no severe thunderstorm areas forecast...
...summary...
severe thunderstorms are not expected on saturday.
...discussion...
a generally zonal pattern across the conus will become more
amplified on saturday with a trough developing across the plains by
the end of the period. a lack of moisture will limit severe weather
concerns saturday and saturday night.
where greater moisture is present across florida, isolated storms
are expected on saturday amid moderate instability and weak height
falls. shear will be on the weaker side (~25 knots) and mid-level
lapse rates will remain weak. therefore, an isolated stronger storm
is possible, but more organized severe storms are not expected.
isolated thunderstorms may be possible north of the warm front from
northern iowa/southern minnesota into southwest wisconsin early
sunday morning given the strong isentropic ascent, but forecast
soundings show relatively meager moisture/instability at this time,
which may preclude more widespread thunderstorm development.
