FNUS73 KLSX 191553 FWSLSX Spot Forecast for LLC Woodland/Glade...MDC National Weather Service Saint Louis MO 1053 AM CDT Thu Mar 19 2026 Forecast is based on ignition time of 1030 CDT on March 19. If conditions become unrepresentative, contact the National Weather Service. .DISCUSSION... Temperatures and relative humidity will be greatly affected by cloud cover. The cloud cover forecast has been increased substantially for late this morning into early afternoon. Temperatures have been lowered slightly which produces higher relative humidity. With this in mind, cloud cover is not being depicted well by model guidance, so my confidence in the temperature forecast is low. Mixing heights are also affected by the lower temperatues and it is likely the morning inversion will take longer to mix out. It is likely that mixing heights will not exceed 1000 feet before 12-1 PM, and may not exceed 1600 feet until 1-3 PM. Again, my confidence in the mixing height forecast is low due to the low confidence temperature forecast. .REST OF TODAY...
