...DISCUSSION...
A benign pattern for severe weather will persist during the D4-D8
period, with minimal potential for even general thunderstorm
activity.

For much of the period, an upper high will remain centered over
northwestern Mexico, with an extensive upper trough developing
across the East. Prior to this eastern trough amplification, a
lower-latitude shortwave trough will move across Florida on
Friday/D4, losing amplitude all the while. Still, a few weak
thunderstorms will be possible. Otherwise, there will be little
chance of thunderstorms except perhaps with a shortwave trough
forecast to affect the Pacific Northwest with strong cooling aloft
around D7 when both potential and predictability will be low.
