...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe storms are unlikely through tonight.
...Synopsis...
Little thunderstorm activity is currently present near the cold
front moving across NY and PA, with only isolated lightning flashes
across WV into western VA. Given the loss of heating, and already
minimal instability present, severe storms appear unlikely to
develop.
Farther south, scattered storms exist over northern AL near the
front, and north of the boundary from LA into central TX. In both
these areas, instability is weak, and generally should not support a
severe threat as the surface air mass cools.
