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

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

....Synopsis...
Strong westerly flow will exist across most of the CONUS, as an
upper trough exits the Northeast and another moves from the Pacific
Northwest into the Great Basin. At the surface, a large area of high
pressure will move from the Mississippi Valley eastward toward the
Mid Atlantic by Friday morning, producing dry and stable conditions.
Low-level moisture and instability will be limited to the Gulf of
Mexico where easterly surface winds will exist. Therefore, while low
pressure will develop over the northern and central Plains in
advance of the western trough, dry air will preclude any
thunderstorm chances there.

To the west, steep lapse rates beneath an upper trough will lead to
scattered low-topped convection across the coastal Pacific
Northwest. Severe weather is unlikely given cold temperatures, weak
instability and weak shear.
