.PREV DISCUSSION... /Issued 358 PM CDT Mon Apr 24 2017/

DISCUSSION...
Southerly winds will stay up tonight which will result in a much
milder night than what we have seen recently. A very warm day will
then follow Tuesday, with some places approaching record highs. A
fair amount of high cloudiness may be just enough to hold
temperatures below record levels.

A cold front will move across the area late Tuesday night and
Wednesday, with scattered to numerous showers and thunderstorms
expected to develop along and ahead of the front. Despite the
unfavorable time of day, strong to severe storms are likely in
northeast Oklahoma Tuesday night, and into far eastern Oklahoma
and western Arkansas Wednesday morning into early afternoon. A
cold rain may linger into Wednesday evening behind the front as
an upper low moves across the area.

The forecast late this week into the weekend remains fraught with
uncertainty. A strong upper level storm system will move out of
the Rockies into the Plains this weekend. The old frontal boundary
will return north as a warm front and will provide a focus for
potential severe thunderstorms, heavy rainfall, and flooding. The
biggest question lies in just how far north this front will
advance, and the trend in the models has been farther to the
south. This may focus the higher severe weather chances to the
southern and eastern parts of our forecast area, with heavy
rainfall/flooding potential to the north, but perhaps not all the
way to the Kansas border. A wide range of temperatures will also
exist across the boundary, and have adjusted the blended
temperatures to reflect the consensus of the various model
solutions.

Sunday looks like a raw day with a few wraparound showers
remaining possible. After a chilly night Sunday night, a quick
warmup is expected early next week.

Stayed close to guidance temperatures the next couple days, with
the coldest guidance preferred behind the frontal boundary
Wednesday.
