SHORT TERM /THROUGH MONDAY NIGHT/

Issued at 300 AM CDT Sun Aug 2 2026

Upper level energy associated with the recent midlatitude cyclone has now pushed into eastern Missouri. Lingering cloud cover is making its way through the eastern portion of the SGF CWA, but will clear out over the course of the morning. Most of the area is currently cloud-free, and we'll see mostly sunny skies today apart from some fair-weather cumulus. Though flow will still be northerly, CAA will be quite weak, and mostly clear skies paired with rising 500mb heights will allow us to warm quite a bit more than yesterday. Highs are expected to reach the upper 80s in our western counties and land right around 80 in the east where cloud cover will take a little longer to move out. Those NNW winds will top out around 10-15 mph.

Tonight, skies clear out and winds die down. With dewpoints in the mid- to upper-60s, this will be a perfect recipe for fog. The HREF is currently indicating an up to 50% chance for visibility to drop below a half mile between 5 and 10 a.m., generally east of Hwy 13 and north of Hwy 60. Several other models are also outputting this signal. At this lead time, only two models are indicating the potential for dense fog to result in visibilities lower than 0.25 miles. This is resulting in a relatively low probabilistic signal, and there is not enough consensus for a DFA to be issued at this time. However, as the short term models begin to resolve tomorrow morning throughout the daytime modeling cycle, future forecasts will be more certain regarding the necessity for fog headlines. At this time, it is safe to say that some in this area will likely see fog, but it still a bit uncertain how dense or widespread it may be. Overnight lows will be in the low- to mid-60s.

Flow on Monday begins to slowly regain a southerly component as surface high pressure passes by. Clear skies and a hint of WAA will help us continue on the warming trend, with highs beginning to reach into the lower 90s out east with mid- to upper-80s elsewhere. Another clear night Monday with lows in the 60s.

LONG TERM /TUESDAY THROUGH SATURDAY/

Issued at 300 AM CDT Sun Aug 2 2026

Synoptic high pressure continues building in Tuesday, and a surface low to the west helps to advect warmer air into our western counties, resulting in highs in the upper-90s here with temps topping out closer to 90 elsewhere. Wednesday will be a couple of degrees warmer still ahead of troughing pushing rain through SOMO Wednesday night into late week. The axis of the trough, which will bring the first round of rain, appears to be followed by one or more shortwaves that will continue to bring rain chances for a couple of days. Long term guidance indicates PoPs ranging from around 30% along the Springfield latitude to around 60 percent into our northern counties beginning Wednesday night. Odds are currently slightly lower Thursday night through Friday, topping out around 30- 40%. The SPC has mentioned the potential for inclusion of portions of the area in future severe weather outlooks, but certainty and coverage are too low at this time.

The initial front appears to stall out as it brings this activity to our area and eventually retreats to the north, leaving us without a true frontal passage. We will keep our steadily warming airmass around, and it may have the potential to warm into Extreme territory by next weekend into mid-August.

AVIATION /06Z TAFS THROUGH 06Z MONDAY/

Issued at 1042 PM CDT Sat Aug 1 2026

Ceilings will most likely remain in VFR through the remainder of the period with gradually clearing skies Sunday morning. Winds will remain out of the north to northwest at or below 10kts overnight with a slight increase in speeds and gusts during the day Sunday.
