.SHORT TERM...(This Evening through Thursday)
Showers were exiting the Ozarks region this afternoon in response
to the passage of a weak upper level disturbance. We left in some
miner pops over the eastern Ozarks for this evening`s period as
some of the short term models were signaling some QPF in that
area, created by weak lift still to come. If anyone does receive
rain, it would range from a trace to just a few hundredths of an

development, but the evening forecasters will need to watch this
Lows tonight will fall into the low to mid 50s.
.LONG TERM...(Thursday Night through Wednesday)
Flow quickly evolves into an unusual split flow pattern tomorrow

popping short term ridging over southern Missouri. This will bring
mostly sunny skies to the Ozarks tomorrow, with highs in the 70s.
Surface winds will be light and variable.
Southerly winds will commence tomorrow night as the upper level
low shifts closer to the region. Anticyclonic flow around this
feature will also transport moisture in from the Gulf.
This will lead to showers and thunderstorm chances heading into
Friday and through the weekend. I`m not sure if we`ll be able to
generate sufficient instability across southern Missouri for an
organized episode of severe storms anytime this weekend. Therefore
we will leave severe storms out of the Hazardous Weather Outlook
for the moment.
Split flow continues into next work week with a possible break
from rain chances Monday and Tuesday, with additional rain chances
starting Wednesday or Thursday, as energy approaches from the
