.SHORT TERM...(This Evening through Friday)
Tenacious cloud cover was the theme today as stratus was trapped
underneath a layer of warm air that was measured on the 12z RAOB
at 6,000 feet. We also had a disorganized surface pressure
pattern, leading to light and variable winds also helping the
stratus to hang overhead.
For the rest of the afternoon, we think cloud cover will slowly
dissipate as upper level height rises build over southern
This upper ridge will support a dry forecast tonight with
overnight lows in the mid and upper 50s.
For Friday, most locations should remain dry, especially through
the morning hours. However, rain chances will start to ramp up
across across southeast Kansas and far southern Missouri during
the afternoon. Look for increasing clouds on Friday with highs in
.LONG TERM...(Friday Night through Thursday)
A large upper level low pressure system can be viewed on the water
vapor imagery directly centered over the Great Basin.
Cyclonic flow around this feature will force deeper moisture into
the nation`s midsection through the upcoming weekend. This will
lead to stormy conditions for the Ozarks through at least Sunday
We don`t think instability levels will be high enough for any
organized severe storms through at least Sunday morning. So on and
off again showers and thunderstorms Friday night through Sunday
morning can be expected.
By Sunday afternoon and evening, there are signals that would
suggest a decent cape - shear combination for organized storms. I
will insert a mention for severe storms for Sunday afternoon into
In addition to severe storms on Sunday, I will also insert a
limited risk for flooding from Saturday through Sunday night. Soil
moisture conditions are around normal to above normal. Meanwhile
stream flows are also running slightly above normal to normal. We
may even have to consider posting a Flood Watch either tonight or
during tomorrows forecast.
A window for dry weather is expected from Monday through Wednesday
as northwest flow briefly cleans out our moisture content.
However, stormy conditions once again appears toward the end of
the next work week.
.AVIATION...(For the 06Z TAFS through 06Z Friday Night)
Issued at 1232 AM CDT FRI APR 17 2015
Light fog will again be possible late tonight and early Friday
morning. However the presence of high cloud cover should preclude
any dense fog potential. A warm front will then lift towards the
region later Friday into Friday evening and may produce widely
scattered showers and thunderstorms. MVFR and brief IFR conditions
can be expected with any thunderstorms. Surface winds will remain
light out of the southeast.
