LONG TERM...Wednesday Night Through Monday
This is the first forecast I have produced in a while that has no
POPs in the extended forecast.
Generally speaking, the upper level pattern is remaining
progressive, albeit less so than during the previous weeks. During
the beginning of the term the central part of the country will be
under a broad trof, with weak ridging along the east coast. By the
end of the term Arkansas will end up between systems, as a ridge
builds across the west and a trof deepens across the east.
Starting on Saturday a meridional flow pattern will start to set in
at the upper levels, which will continue to bring cooler air aloft
to the region. At the surface, high pressure across the western US
will allow cooler and drier air to continue filtering in across the
plains into the south-central US, which will keep temps at or
slightly below climo. A southerly flow will eventually return to the
surface as a high settles into the southeast late in the period.
