.SHORT TERM /THROUGH TUESDAY/...
Issued at 301 PM CST Mon Jan 20 2025
An upper level trough is moving south into the region this
afternoon and will continue to move south through the area this
evening and tonight. There is a low chance that a few flurries
occur ahead of the trough this evening, but a dry air mass is in
place which will limit this potential with the better potential
remaining west of the area.
A cold air mass remain in place across the region as
temperatures are currently in the upper teens to lower 20s this
afternoon. Lows tonight into Tuesday morning will drop to a few
degrees above to a few degrees below zero (-4 to 4 range).
Surface high pressure will move east across the Plains tonight
into Thursday. Northwesterly winds will occur tonight and will
increase to up to around 10 to 15 mph at times tonight into
Tuesday morning. The winds will start to weaken from west to
east Tuesday morning as the surface high moves east towards the
region. Wind chill values will drop into the 5 to 15 below zero
range tonight into Tuesday morning. A Cold Weather Advisory is
effect for the area from 12am tonight to 12pm Tuesday to account
for the cold conditions.
The cold air mass will remain in place across the area on
Tuesday as highs only warm into middle teens to the lower 20s.

.LONG TERM /TUESDAY NIGHT THROUGH MONDAY/...
Issued at 301 PM CST Mon Jan 20 2025
The surface high starts to move off to the east Tuesday night
into Wednesday allowing southerly winds to return along with a
warming trend. Highs on Wednesday and Thursday will warm into
the upper 30s to the lower 40s which is closer to normal for
this time of year. Winds could be gusty at times on Wednesday as
the pressure gradient tightens behind the surface high. The
models show another upper level trough moving through the region
later Wednesday into Thursday. A drier air mass will be in
place across the area, but there will be the potential for some
flurries as the trough moves through the area. No accumulations
or impacts are expected at times.
A more zonal upper level flow pattern will then set up over the
region behind the trough late this week into the start of the
week. A warmer air mass will advect into the region as highs
warm into the 40s with highs in the 50s possible on Saturday.
The ensemble model members then indicate that an upper level
trough will dig south across the western CONUS this weekend
with a trough moving trough the region late this weekend
bringing chances for rain (10-30%) to the area Saturday night
into Sunday. Overall the models are showing the better rain
potential being south and east of the area. The models then
differ on the track and timing of the low moving east next week.
