....DISCUSSION...
Surface high pressure will build into the eastern CONUS this weekend
and usher in an extended period of cooler and less humid weather for
much of the eastern CONUS with reduced severe weather chances. Some
severe weather chances will remain from the central High Plains to
the northern Plains where low-level moisture is expected to remain.
Several weak embedded mid-level shortwave troughs may result in some
thunderstorm activity from the central to northern High Plains amid
moderate to strong instability. A few severe storms are possible
early next week with any of these passing troughs.

There is some signal that a more organized severe weather threat
could materialize by the middle of next week as strong instability
builds across the northern Plains and stronger mid-level troughing
and flow becomes more prevalent across the region. However,
predictability is low within this low-amplitude pattern. There is
not much consensus for the overall pattern beyond D6/Monday and
therefore, no severe weather probabilities are warranted at this
time.
