Area Forecast Discussion...Updated Aviation National Weather Service Saint Louis MO 1132 AM CST Sat Mar 7 2026 .KEY MESSAGES... - Showers and thunderstorms will end from northwest to southeast this morning across the area. - There is another chance of showers and thunderstorms Tuesday into Wednesday. && .SHORT TERM... (Through Late Sunday Afternoon) Issued at 450 AM CST Sat Mar 7 2026 Numerous showers and thunderstorms continue to move east ahead of a cold front that now extends from southeast Iowa into southeast Kansas in the right entrance region of jet streak. The cold front is not expected to move through the CWA until early this afternoon, so this area of showers and thunderstorms will be slow to move from northwest to southeast across the area this morning, and will linger across southeast Missouri and south central Illinois this afternoon. Subsequently, clouds will not clear out of the area until late this afternoon and this evening causing highs today to be 10 to 25 degrees cooler than yesterday. Dry weather is expected tonight and on Sunday across the area as the upper flow transitions to quasi- zonal flow. Lows tonight will drop back into the 30s as a surface ridge moves across the area and highs tomorrow will climb back into the 60s with southwesterly flow and full sunshine. Britt && .LONG TERM... (Sunday Night through Friday) Issued at 450 AM CST Sat Mar 7 2026 The dry weather will continue into Monday before the next system moves through the central CONUS the middle of next week. The LREF is showing a deeper trough today which goes along with each of the determistic models showing a more phased solution. There is consistency with the NBM as it keeps Tuesday through Wednesday having the highest PoPs (70-90%) and the LREF has the same percentage of its members producing rain at St. Louis from late Tuesday into Wednesday morning. There continues to be signal for strong to possible severe thunderstorms on Tuesday as the LREF is showing sufficient shear and instability developing. We will also need to watch the potential for some locally heavy rainfall given the orientation of the attendant front with the upper flow. Temperatures on Monday and Tuesday look to warm back up into the 70s to near 80 before cooling back down in the 50s and 60s late next week behind the mid week front. Britt && .AVIATION... (For the 18z TAFs through 18z Sunday Afternoon) Issued at 1129 AM CST Sat Mar 7 2026 A cold front has moved through the terminals earlier today and will continue to progress eastward. High IFR/low MVFR ceilings are expected this afternoon, but should slowly lift. The clouds should exit from west to east tonight, which does raise the concerns for fog. Guidance isn't really hitting it too hard, though I would be most concerned about river valleys in east central/southeast Missouri. This is where winds should lighten up. Light winds combined with a clearing sky and lots of extra surface-level moisture from recent rainfall should lead to some fog development. Did not add to any of the terminals yet, but KSUS followed by KJEF/KCPS are most prone to seeing fog late tonight into early Sunday morning. The light/variable winds tonight should turn out of the southwest on Sunday morning. Gosselin && .LSX WATCHES/WARNINGS/ADVISORIES... MO...None. IL...None. && WFO LSX
