…NO THUNDERSTORM AREAS FORECAST…
…SUMMARY…
Thunderstorms are not expected over the contiguous United States
today.
…Discussion…
A progressive/relatively low-amplitude large-scale flow regime will
prevail over the CONUS through tonight, although some amplification
will occur as a shortwave trough continues east-southeastward from
the central Plains to the Ohio Valley/central Appalachians tonight
and early Tuesday.
In response, a surface low will deepen tonight as it develops
northeastward across the Lower Mississippi Valley to Tennessee
Valley in conjunction with a sharpening cold front. Near the
low/front, convection should develop/increase late tonight across
the Tennessee Valley including northern Alabama and Middle/eastern
Tennessee to northern Georgia. While a thunderstorm or two cannot be
entirely ruled out, most forecast soundings suggest that this
elevated convection will be shallow within a non-lightning-conducive
thermodynamic profile.
