.PREV DISCUSSION... /ISSUED 359 PM CDT SUN MAY 22 2016/

DISCUSSION...
The upper ridge is shifting off to the east and we will be under
the influence of the western U.S. trough for at least the next
week or so. The dryline will remain well to our west for most of
the week, but we will be at risk of seeing at least the remnants
of any storms that develop well to our west making it far enough
east to affect us. Weak impulses moving out of the western trough
may also trigger scattered showers and storms within our forecast
area just about any day this week. Instability will be sufficient
for severe storms, especially from Tuesday on.

The main upper system will finally lift northeast into the central
Plains by Friday, perhaps 12 hours or so sooner than it appeared
at this time yesterday. Thus Friday will likely see the greatest
precipitation coverage, and greatest severe weather risk, of the
week.

Even after this system lifts out, another trough develops near the
West Coast, and the dryline gets left behind to our west, so storm
chances will continue through next weekend, as will the warm and
humid conditions.

Stayed close to guidance temperatures the next couple days.
