...DISCUSSION...
An upper low is forecast to drift very slowly northeastward across
the Nebraska/South Dakota vicinity Day 4/Friday, while a second/weak
disturbance moves out of northern Mexico into central and southern
Texas. While thunderstorms -- and some severe potential -- will
likely occur in the vicinity of these two features, risk appears too
low to highlight with a 15% area at this time.
For the remainder of the period, weak flow aloft is forecast across
all but the Northeast/Great Lakes region, which should generally
limit severe potential on the broader scale. As a blocking high
develops over western North America and lingers through the medium
range, eastern U.S. troughing will gradually evolve. While this
increase in troughing -- and the magnitude of the upper flow field
-- could lead to some increase in potential for severe weather
through latter stages of the period, differences amongst the models
suggest limited predictability of the pattern evolution.
