KEY MESSAGES

- Lows in the mid to upper 30s early Sunday morning with a Frost Advisory in effect until 9 AM.

- Steady warming trend and a pattern change around midweek bringing potentially prolonged rain chances through the weekend.

SHORT TERM /THROUGH MONDAY NIGHT/

Issued at 221 AM CDT Sun Apr 5 2026

The Ozarks remain subject to troughing associated with the cold front that moved through yesterday, supporting the marginally severe storm activity we saw. Though the front has moved off and we are not at risk for any precipitation, the northwest flow remains through a deep atmospheric column. Coupled with cloudless skies, CAA and radiational cooling are working together this morning to drop our low temperatures into the mid to upper 30s. For this reason, a Frost Advisory has been issued until 9 AM, particularly because the abnormal warmth as of late has allowed for agricultural bloom that could be harmed by the sudden cold air.

Post-frontal surface high pressure continues to push into the area today, but the northwest flow will hold in the meantime. Clear skies today will allow for temperatures to get a few degrees warmer, generally ranging 60-65. Winds die down tonight as the surface low passes overhead. The night will be clear and calm with lows around 40.

Flow is a bit split on Monday with a surface high to the south and an inverted ridge to the north, so wind directions will vary. Clear skies allow high temperatures to warm to around 70 along the southern border and into the mid-60s closer to central Missouri. Clouds start to filter in from the north in the evening as the boundary in the inverted ridge begins to initiate lift. Some models break out precipitation along this front Monday night, but limit it to primarily north of the CWA. Our very northernmost counties, Morgan and Benton, have a 20-30% chance of seeing some of this activity at this time, but may very realistically stay dry. Low temperatures continue to warm a few degrees and will land in the upper 30s to low 40s.

LONG TERM /TUESDAY THROUGH SATURDAY/

Issued at 221 AM CDT Sun Apr 5 2026

Southerly flow begins to return Tuesday as we get sandwiched between the Midwest high pressure and incoming low pressure in the lee of the Rockies. Southeast winds could reach 15-20 mph west of Hwy 65. The warming trend is briefly interrupted as the cold air to the east sags west a bit due to the low pressure pushing in from the northwest, but we still land in the 60s.

The main low pressure center comes bowling into the Northern Plains on Wednesday, and our pressure gradient tightens significantly as the front begins to push in. West of Hwy 65, winds could gust up to 30-35 mph with sustained winds up to 20 mph. Elsewhere to the east, sustained winds should remain under 15 mph with some gusts up to 25 mph. All of this flow is directly out of the south, allowing for our high temperatures to reach the mid-70s. The warm front passes sometime late Wednesday, but the cold front seems to lag and stall, putting us in the warm sector for potentially a couple of days. I-44 and north have 30+% PoPs Thursday with higher chances moving in and covering the rest of the area Friday and Saturday. Despite the precipitation, our time in the warm sector with southerly flow allows temperatures to continue warming. Highs in the upper 70s to near 80 are expected late week through the weekend. Statistical spreads start to get bigger around Friday and later, with interquartile ranges around 8 degrees spanning the mid 70s to low 80s. So, we still at least expect to be about 10 degrees above normal.

This active pattern change is expected to stick around. A significant portion of the country is expected to see precipitation of some kind by late week, continuing into early next week. WPC is highlighting our far southwestern CWA in an area at risk for heavy rainfall Friday and Saturday. The CPC highlights a large corridor of the U.S., from nearly the Texas-Mexico border up through our area and to the Michigan-Canada border, as at risk for heavy precipitation Sunday and Monday. With that in mind, there is hardly anything of note on the SPC convective outlooks through day 8.
