.SHORT TERM /THROUGH FRIDAY/...
Issued at 235 PM CST Wed Feb 19 2025
Some isolated light snow flurries have been observed across the area
this morning and early afternoon, however little to no
accumulations have been reported. Travel conditions remain
fairly hazardous across the area, especially on the more rural
roadways, with the MODOT Travelers Map highlighting most (if
not all) of southwest into central MO showing partly to fully
covered roads.
An extensive 1052mb surface high continues to settle into the
region, filtering an arctic airmass into a large portion of the
central CONUS. As a result, temperatures so far this morning/early
afternoon have remained in the single digits/low teens, and are only
expected to climb a few more degrees, with afternoon highs ranging
in the teens. Additionally, with northerly winds between 5-15mph
occasionally gusting up to 20mph, wind chill values will remain
near zero and into the negatives. A Cold Weather Advisory
remains in effect for the entire area through this evening and
tonight (and for parts of the area through noon tomorrow - more
on this in the next paragraph).
Dangerous cold will continue through tonight, as overnight lows
range between 0 to -10 degrees, putting record lows in jeopardy
(see Climate section below). Northerly winds gusting up to
20-25mph will drop wind chills into the -13 to -23 range. A Cold
Weather Advisory remains in effect for the entire area through
midnight, and for the northern tier of counties (towards central
MO) until noon tomorrow. Elsewhere, we've upgraded to an
Extreme Cold Warning to account for the dangerous wind chills
and continued impacts across southwest/south-central MO and
southeast KS. This is in effect beginning at midnight tonight
until noon tomorrow.
The main message is that hazardous roads combined with dangerous
cold will continue the impacts across the area. It's imperative to
take the necessary actions to prevent hypothermia or frostbite by
dressing in layers, covering all exposed skin, and limiting time
outdoors. If you have to go out on the roads tonight, make sure to
have an emergency kit prepared that includes warm clothing,
blankets, and any other items that can keep you warm if needed.
The cold weather will continue on Thursday, with afternoon highs
once again topping out in the teens across the area, and overnight
lows around zero. Record lows will again be in jeopardy at our
climate sites Thursday night.

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
Issued at 235 PM CST Wed Feb 19 2025
Subtle mid level height rises will lead to "warmer" conditions on
Friday. However, with the snowmelt still expected over the area,
temperatures should remain in the upper 20s to low 30s during the
afternoon, leading to minimal additional melting.
By this weekend we'll begin to see a warming trend over the region,
with highs gradually climbing to the upper 30s on Saturday and the
upper 40s to low 50s by Sunday. This warming trend will continue
through at least midweek, with highs in the upper 50s to 60s Monday
through Wednesday.
&&
.AVIATION /06Z TAFS THROUGH 06Z FRIDAY/...
Issued at 1100 PM CST Wed Feb 19 2025
High confidence in VFR conditions prevailing through the TAF
period. Scattered high level clouds move through the area
overnight. North to northwest winds around 5 to 10 knots.
