Area Forecast Discussion
National Weather Service Springfield MO
557 PM CST Tue Feb 16 2021
.SHORT TERM...(This evening through Wednesday)
The historic cold wave of 2021 continues across extreme southeast
Kansas and the Missouri Ozarks. Frost depth at noon was measured
at 7 inches, and will increase more into record territory in the
coming days.
For tonight, our next winter system will approach, forcing snow
to spread from southwest to northeast across the region late
evening into the overnight hours.
We utilized the National Blend of Models 75 percentile for QPF,
and made some modifications to formulate the snow amounts.
Generally 1 to 4 inches are expected, with the higher amounts
along the Oklahoma and Arkansas borders. Lesser amounts are
likely to the north in west central and central Missouri.
Light snow and flurries will continue through mid day Wednesday in
very light fashion. Most of the accumulations will occur prior to
day break, therefore, the Wednesday morning commute to work or
school will be impacted. High temps on Wednesday will only warm
into the low 20s.
.LONG TERM...(Thursday through Tuesday)
The cold wave will continue into Thursday and Friday with
overnight lows Friday falling back into the low single digits.
Temperatures Friday will probably struggle to warm back over
freezing especially with the snowpack in place. So mid to upper
20s is more likely for highs on Friday.
Most locations on Saturday will break above freezing for the first
time since February 6th, due to upper level flow shifting into a
zonal regime offering southerly winds beneath it. Highs on Sunday
are progged to warm back into the 40s.
Dewpoints will surge to near 40 on Sunday ahead of a Pacific based
cold front. Rain will develop ahead and along this front,
spreading through the region Sunday afternoon into Sunday evening.
We think this front will be fast and progressive, therefore, QPF
doesn't look too bullish.
With the ground completely frozen through 7 inches, flood
sensitivity will be very high. However, at this time, Sunday's
QPF shouldn't yield enough for flooding. QPF trends need to be
watched closely.
All indications suggest that the upper flow remains zonal heading
into next work week, possibly bringing temperatures back into the
50s by next Tuesday.

visibilities will fall to IFR to LIFR conditions at times.
Impacts to the regions aerodromes is expected to continue through
the day Wednesday and into the evening.
Some improvement is expected to occur Wednesday night into
Thursday.
