SHORT TERM /THROUGH SUNDAY NIGHT/

Issued at 130 PM CDT Sat Apr 18 2026

Today-Tonight: Friday's system continues to slide south and east of the region this afternoon, with mid to high level cloud cover gradually dissipating. The lingering cloud cover will keep areas southeast of Interstate 44 a bit cooler today, with highs in the middle 50s. Elsewhere, highs are expected to top out in upper 50s to near 60. This is around 10 degrees below normal for mid April. Residual flooding continues across the area, in particular across southeast KS into west central MO where a band of 2 to 4 inches occurred. Additionally, gusty north- northwest winds persist through the remainder of the afternoon before high pressure gradually settles into the area. Winds gusts around 20 to 25 mph will make it feel quiet chilly compared to previous days.

Expect winds to taper off into the evening as the surface high builds into the region. With clear skies and light winds, sufficient radiational cooling will occur. Lows tonight are progged to fall into the middle to upper 30s, to near 40. NBM interquartile spread remains small. For example at Springfield, the range depicts the 10th percentile as low as 34 degrees to 90th percentile at 39 degrees. We are expecting the temperatures to fall somewhere in between this range, for around 2 to 4 hours early Sunday morning. This opens the door for frost potential. Given that most locations are expected to remain around 36 or higher, the frost would likely be patchy in nature. This would generally occur in low-lying and sheltered areas along the Highway 60 corridor and into the Eastern Ozarks. Confidence remains high that a freeze in not in the cards for tonight.

Sunday: A chilly start on Sunday morning with return flow slowly taking shape into the afternoon. This will support highs into the upper 60s to near 70 on Sunday. A northwest flow pattern aloft suggests drier conditions persisting into the end of the weekend. Lows in the 40s on Sunday night.

LONG TERM /MONDAY THROUGH FRIDAY/

Issued at 130 PM CDT Sat Apr 18 2026

Monday-Wednesday: Northwest flow aloft takes shape through early next week, with low-level flow becoming more southwesterly in nature. This will help a gradual warming trend, as highs climb into the 70s. Lows fall into the 50s. Rain chances remain less than 10 percent each day through Wednesday.

Thursday-Friday: Ensemble guidance is coming into better agreement that a trough builds out of the Western CONUS into the Rockies by Thursday, with warm air advection increasing ahead of this system. As temperatures push towards 80, low-level moisture builds into the area. NBM guidances depicts a return of shower and thunderstorm chances (40-70%) by Thursday afternoon/night. Additionally, CIPS Analogs and CSU Machine Learning hint at the potential for severe weather chances. There is still much remaining uncertainty with the details of the impending system(s), and stakeholders should continue to monitor for updates. Additional rain chances linger beyond Thursday into next weekend.
