SHORT TERM /THROUGH FRIDAY/

Issued at 237 AM CDT Thu Jun 4 2026

Surface high pressure is overhead and light southerly winds are occurring over the area. Lows are in the mid 60s tonight with clear skies. Today moisture returns to the area with dewpoints steadily increasing through the day. Dewpoints will be 10 degrees higher today than they were yesterday as they top out in the mid 60s. Clouds also start to increase today but high temperatures will still reach the lower 80s. A shortwave also moves through this afternoon and will bring a chance (30-50%) for showers and thunderstorms. As of right now, convection is expected to remain sub-severe and very isolated. CAMs have most of the activity remaining west of Highway 63 where the better moisture will be. So, not everyone will see rain today and where there is rain, accumulations will be light at <0.50". Any remaining convection will dissipate as diurnal heating wanes this evening.

A mid-level trough will move through the Great Lakes region on Friday with a sweeping weak front bringing us a chance (15-30%) for showers and a few rumbles of thunder by the afternoon/evening. Due to the track of this low pressure system, most of the convection will likely occur east of Highway 65. Not everyone will see rain with the system on Friday, and no widespread severe weather is expected. Friday will be partly cloudy with highs in the mid to upper 80s.

LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/

Issued at 237 AM CDT Thu Jun 4 2026

As we move through the weekend, another mid-level trough (this one located over OK) will move through the area and drop rain over southern MO. A moist airmass creeps in and dewpoints increase into the upper 60s to lower 70s for this weekend with our rainy pattern returning. Right now, chance for rain is 20-40% for Satruday afternoon Sunday is 60-80% and features the highest chance for rain this weekend. Not everyday will be an all day washout, but there will likely be intermittent rain showers and maybe a few rumbles of thunder. No widespread severe weather is expected at this time. Flash flooding will be a threat and any showers we do see will likely be efficient rainfall producers and could lead to flash flooding within brief heavy downpours. The Weather Prediction Center has issued a Marginal Risk for flash flooding for most of the area for Saturday through Monday. This is likely to account for the elevated river levels and saturated soils due to last week's rainfall.

As for high temperatures this weekend, expect low 80s and then our warm up starts next week as highs increase into the upper 80s by Wednesday. It will feel warm and muggy with dewpoints in the mid 70s by mid-week. Lows for the long term period also stay fairly warm in the mid 60s and lower 70s.

AVIATION /12Z TAFS THROUGH 12Z FRIDAY/

Issued at 600 AM CDT Thu Jun 4 2026

VFR through the period with southerly winds gusting around 10 knots today. Near 20z, pop-up thunderstorms are expected to develop around the area, with only a 30% chance for any of them to briefly impact the vicinities of the TAF sites. Lightning and brief reductions in visibility would be the main hazards.
