A upper level trough is moving across the Red River Valley this
morning and will continue to move east across southern Arkansas
today. Moisture is streaming north ahead of this system this morning
continuing showers that began last night. Shower are expected to
continue through this morning and perhaps linger into early this
afternoon as this system moves by to the south. Models are
indicating a deformation type band setting up across the area along
a 700mb front and it is along this front precipitation will be
focused. But again, precipitation will come to an end early his
afternoon. However, cloudy skies will prevail throughout the day and
with CAA, high temperatures will only achieve the upper 30s to upper
40s. Tonight, fog again may become an issue especially across the
western CWA where skies are expected to clear and winds will become
light as surface high pressure moves into the area. Surface high
pressure will dominate the area Monday as upper level ridging builds
across the region in response to a trough digging down the West
Coast. Expect highs in the 40s on Monday.

The aforementioned West Coast trough moves into the Plains on
Tuesday forcing a cold front into the eastern Plains by Tuesday
afternoon. Temperatures should warm nicely across the area ahead of
the front with modest WAA. Expect highs Tuesday to range from the
upper 40s across the north where showers will be possible beginning
early in the day to the lower 60s across the south. Rain showers
will overspread most of the CWA Tuesday afternoon and continue into
Tuesday night with the highest PoPs across the northern CWA. Some
rain may mix with or change over to snow across the northern CWA
early Wednesday morning and continue through the morning hours.
Temperatures on Wednesday across the northern CWA will range from
the low to mid 30s so any accumulation looks to be minimal at this
time. Elsewhere across the CWA, highs will range from the upper 30s
to lower 40s with rain the predominant p-type through the period.
Precipitation will exit the area Wednesday night as the upper level
trough shifts into the Great Lakes region. This will leave the area
under cold northwest flow aloft through the remainder of the work
week keeping temperatures cool. Highs Thursday through Saturday will
be in the 30s to near 40 however, conditions will remain dry.

Issued at 524 AM CST SUN JAN 22 2017

IFR cigs with an occasional lgt shower will be possible as MKC
and IXD thru 15Z otrw...MCI and STJ will remain VFR. By late
morning, cigs will become VFR. This evening, models are indicating
stratus moving into the terminals around 5kft however there may
be a pd btn 23Z-03Z where cigs may temporarily drop to btn 2-3kft.
Stratus will move out of the terminals around 06Z with just sct-
bkn high clouds however, that will lead to the potential for fog
formation at the tail end of the TAF pd. Due to uncertainty in
cloud cover tomorrow morning have not included fog in the TAF at
this time. Winds are out of the north this morning around 10kts
but will increase to 10-15kts with ocnl gusts to 20-25kts this
afternoon. Winds will subside this evening as high pressure moves
into the terminals. Winds tomorrow night will veer to the
northwest while dmshg to 5-10kts.
