.SHORT TERM /THROUGH TUESDAY/...
Issued at 130 PM CST Mon Jan 6 2025

A 1045mb high is forecast to shift from southern Canada into the
Dakotas tonight, leading to dry and cold conditions across the
Midwest. Locally, temperatures will drop into the single digits and
teens tonight with a rebound into the 20s for highs on Tuesday.
Overall, a very quiet start to the workweek is expected.

.LONG TERM /TUESDAY NIGHT THROUGH MONDAY/...
Issued at 130 PM CST Mon Jan 6 2025

Through Wednesday, our forecast will see a strong Canadian high
pressure just west of Iowa, resulting in north/northwest winds and
cold advection. Like many of this winter`s cold intrusions,
this will arrive with little snow pack preexisting for the CWA,
and temperatures will be cold, but nothing remarkable for
nearing our climatological coldest weeks of the year. Lows in
the single digits to low teens with highs in the upper teens to
mid 20s are forecast through Thursday.

Late week, the NBM has introduced 20-30% chances for light snow
on Friday as a broad upper trough passes through the Midwest
and a more pronounced trough crosses the southern states. The
CMC and GFS from 12Z are showing light QPF over portions of the
outlook area, coming in from the southwest. However, the latest
EC has little in the way of phasing between the two
aforementioned troughs and is mainly dry for our area.
Temperatures look to warm slightly by the weekend with highs in
the mid 20s to lower 30s.

.AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/...
Issued at 530 PM CST Mon Jan 6 2025

Current GOES-East nighttime microphysics imagery shows an MVFR
low stratus cloud deck lingering over MLI and BRL, with SKC for
points northwest. This stratus deck should eventually clear out,
leading to a period of clear conditions. Farther west, a mid-
level cloud deck will move in tonight and thicken, but dry
conditions will prevail. Light and variable winds are expected
tonight into Tuesday morning.
