.SHORT TERM /THROUGH TUESDAY/...
Issued at 132 PM CDT Mon Apr 7 2025

An upper level trough is currently extending from northeast Canada
down into Mexico, with an upper level shortwave embedded within this
trough located just east of the Ozarks. Upper level ridging is
building over the region, bringing northwesterly flow aloft and
surface high pressure to the region. Surface low pressure over the
Great Lakes region is progged to push eastward through today,
dropping a weak, dry cold front south through our forecast area
today and tonight. As a result, another chilly night is in
store, with overnight lows in the upper 20s to low 30s, with the
higher end of that range (low to mid 30s) towards the MO/AR
border. With temperatures below freezing, mostly clear skies,
and light winds, conditions are favorable for widespread
frost/freeze to occur on sensitive vegetation. A Freeze Warning
is in effect for the entire area from 11 PM tonight until 9AM
Tuesday morning.

The upper level ridge continues building over the region on Tuesday,
with surface winds shifting out of the south. As a result, warm air
will begin advecting into the region, bringing afternoon highs in
the upper 50s (eastern Ozarks) to mid 60s (increasing further west
of Hwy 65). With the high pressure remaining in place at the
surface, conditions will remain dry through the short term.

.LONG TERM /TUESDAY NIGHT THROUGH MONDAY/...
Issued at 132 PM CDT Mon Apr 7 2025

On Wednesday, an upper level shortwave is progged to begin tracking
from the northern Plains towards the Ohio Valley. An associated
surface low is progged to push from the Central Plains towards the
Great Lakes region, lifting a warm front through the area Wednesday
morning. With further warm air advecting into the Ozarks, afternoon
highs will climb into the low to mid 70s for much of the area.

Additionally, the surface low will drag an associated cold front
through the region Wednesday night into Thursday morning, bringing
low end shower and thunderstorm chances (15-25%) primarily
northeast of I-44, increasing towards central Missouri. As the
shortwave energy continues pushing through our area Thursday
morning/afternoon, additional shower/thunderstorm chances
(30-45%) exist, primarily for areas northeast of Hwy 60. Current
NBM probabilities of 24-hour precipitation only show a 20-40%
chance of these areas seeing >0.10" of rainfall, with only a
10-20% chance of >0.20", so any rain will be fairly light.

Once this shortwave pushes east of the area, another upper level
ridge will begin to build over the region, raising mid-level heights
and returning surface high pressure. A warm front will lift through
the area this weekend, further advecting warm air into the area. As
a result, temperatures will climb into the upper 60s to low 70s
Saturday, and into the mid to upper 70s Sunday and Monday (and
potentially near the 80s by early next week).

.AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/...
Issued at 546 PM CDT Mon Apr 7 2025

Confidence is high that VFR conditions will prevail through the
TAF period with just a few clouds to start the period. Clear
skies are then expected for Tuesday. Winds will start out
northwesterly with speeds decreasing overnight and gradually
turning easterly and then southeasterly on Tuesday.
