KEY MESSAGES

- Slow warming trend through the week.

- Prolonged rain chances beginning midweek through the weekend.

SHORT TERM /THROUGH TUESDAY NIGHT/

Issued at 244 AM CDT Mon Apr 6 2026

Surface high pressure sits directly overhead early this morning, with calm winds being reported across the majority of the area. Clear skies and low temperatures into the mid to upper 30s may allow for some patchy frost, though this airmass is pretty dry, so we're not expected to cool to saturation in most areas. Winds remain calm through the day, but plenty of sunshine and deep high pressure will help us warm into the upper 60s to around 70.

A band of precipitation is expected to set up in western Iowa extending down into central Missouri tonight, but all signs point to this activity remaining north of the area. It reaches it southernmost extent after midnight, and may sweep some snow flurries across west-central MO through Tuesday morning (again, north of our CWA). Lows are a little bit warmer than last night, mostly in the low 40s with some high-30s still hanging around in the north/east/low-lying areas.

High pressure pushes east tomorrow, and we return to southerly flow. The pressure gradient also starts to tighten up with the incoming low from the west, so we'll have a modest southeasterly breeze. More cloud cover begins filtering in, so we won't have as much sun as recent days, and we'll only warm into the 60s. But, the cloud cover overnight will help lows to stay up in the 40s (and near 50 to the west).

LONG TERM /WEDNESDAY THROUGH SUNDAY/

Issued at 244 AM CDT Mon Apr 6 2026

On Wednesday, as the primary upper level wave begins to descend south from Canada, a shortwave ejects out of Oklahoma. This shortwave arrives first, and may produce some isolated showers along the far northern fringes of the area. Southerly winds increase significantly, especially west of Hwy 65, where gust speeds may reach 30-35 mph. We'll have a bit of sun peeking through Wednesday, but the strong WAA will primarily be to blame for highs reaching into the low 70s. Lows will be warm too, remaining in the 50s.

The main front approaches from the northwest sometime Thursday, and then...stops. It appears to stall out somewhere in eastern Kansas/western Missouri, parking our area in the warm sector over several days. Warm air and moisture will continue streaming into the area through late week and the weekend, and rain chances up to 50- 70% will exist each day. We'll also continue warming up a little each day, with widespread highs near 80 by Saturday. It does not appear there is a simple frontal-passage resolution to this setup in the short term, but rather the overall pattern becomes very chaotic behind this wave, and how things progress into early next week are unclear at this time.

WPC has highlighted the northwestern portion of the CWA (generally north of I-44) in a Marginal risk for excessive rainfall (risk of rainfall exceeding flash flood guidance) Thursday and Friday. The CPC 8-14 day outlook indicates a slight lean toward above normal precipitation and temperatures, and the hazards outlook indicates a moderate risk for heavy precipitation early next week.

AVIATION /12Z TAFS THROUGH 12Z TUESDAY/

Issued at 620 AM CDT Mon Apr 6 2026

VFR conditions through the period. Upper level clouds increasing after 00Z. Light and variable winds, though southeast winds begin to tick up toward the end of the period and into the next.

SGF WATCHES/WARNINGS/ADVISORIES
