....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Severe thunderstorms are not expected today.

....Synopsis...
A leading shortwave trough will move quickly across the Great lakes
and Northeast, within a larger-scale area of cyclonic flow aloft
around a Hudson Bay low. Primarily westerly flow aloft will exist
over the remainder of the CONUS, except for the coastal Pacific
Northwest where an upper low will be just offshore. Here, a few
lightning flashes with limited coverage will be possible off the
coast.

A cold front will be positioned roughly from eastern TX to the OH
Valley Saturday morning, and will quickly push eastward with high
pressure behind. Scattered showers will likely occur in association
with this fast-moving front, but instability will be quite limited
for thunderstorms. However, sufficient elevated instability will
exist during the day for sporadic lighting flashes over the northern
Gulf Coast and perhaps toward the Mid Atlantic early in the day,
with little large-scale support.
