.KEY MESSAGES...
- Dry conditions expected through Friday night, with increasing chances
(60-80%) of a light wintry mix during the daylight hours
Saturday
- Some light icing will be possible across our south Saturday
morning, along with light snow accumulations north
- Dry and seasonable start to next week, with a more active
weather pattern Tuesday and Wednesday

.SHORT TERM /THROUGH FRIDAY/...
Issued at 222 PM CST Thu Feb 6 2025
Dry conditions continue tonight through Friday, thanks to an area of
high pressure that will gradually move through the area. Some subtle
mid-level ridging over the Intermountain West states will also help
keep any shortwaves at bay. The 06.12z HREF ensemble does suggest
increasing cloud cover tonight, but it should remain in the mid- to
high-levels of the atmosphere, so no precipitation should be
associated with them. It will be a cold night ahead, with tonight`s
lows dipping to the middle to upper teens for most.
The clouds should stick around at least through the early part of
the day, with perhaps some peeks of sunshine across our southern
areas. With skies being largely cloudy, have cooled the daytime
highs Friday slightly, but they should still warm to the lower to
middle 30s over the area.
&&
.LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/...
Issued at 222 PM CST Thu Feb 6 2025
Things get a bit more active starting late Friday night into
Saturday, as the mid-level ridging breaks down and a stout 150+ kt
upper-level jet develops from the west. A mid-level
shortwave/clipper system is progged to sweep just north of our
region over southern MN into central WI, with several inches of snow
expected up that way. Concurrently, an area of low pressure is
expected to develop over the OK/TX Panhandle region and help lift a
corridor of 850-700 mb layer warm air advection towards our southern
region. Prior to 12z/6 AM Saturday morning, moisture appears to be
lacking as the HREF ensemble soundings suggest only around a 2000 ft
saturated layer, which is on the marginal side for any drizzle to
form. Moisture should increase further on Saturday, leading to a
wintry mix of snow to the north, with perhaps some freezing drizzle
or rain to our south. Due to limited moisture, any snow or icing
amounts should remain limited. In terms of snow, the NBM exceedance
probabilities of an inch total is around 50 to 70% for our northern
tier of counties, with 30 to 50% chances of 2 inches in total, which
is an increase in the probabilities over the last 48 hours via
dProg/dt. In terms of icing, it`s a bit more uncertain on the
amounts, especially if the precip falls as drizzle, which the models
tend to struggle to capture due to its very light nature, but we
will have to watch this as even a little bit of ice can lead to
travel difficulties. Eventually, these two systems will phase with
each other east of our forecast area and progress eastward.
Saturday night through Monday looks to remain dry in the wake of the
light wintry mix. Cold air advection behind the departing clipper
should lead to a few chilly nights Saturday night and Sunday night,
with overnight lows in the lower to middle teens each night, with
isolated single digits above zero far north.
Monday night through Wednesday will be a period to watch as some
larger systems are progged to sweep across the central portions of
the CONUS. At this time, the bulk of the moisture appears to remain
south of our region, with us moreso on the northern fringes. The
latest NBM is only suggesting 20 to 40% chances of precipitation
with this, and not much in terms of amounts either, but a shift in
the track of the system could change this. Confidence is high that p-
types with these systems should remain all snow.

.AVIATION /06Z TAFS THROUGH 06Z SATURDAY/...
Issued at 1041 PM CST Thu Feb 6 2025
Decreasing winds will be the main change as we head into the
overnight hours, with any gusts near DBQ reducing to under 10
kts by 08-10Z this morning. Light winds will continue into
Friday and Friday evening with VFR/clear conditions.
