.KEY MESSAGES...
- Weak surface flow will allow for a generally dry day today, though isolated showers may be possible in the eastern Ozarks tonight into Saturday morning.
- More seasonal temperatures and additional rain chances will occur into the weekend and early next week. While most rain chances will be isolated to scattered, there is potential for at least one day to see more widespread rainfall.

.SHORT TERM /THROUGH TONIGHT/... Issued at 249 AM CDT Fri Sep 19 2025
A few lingering, but dissipating, light showers remained on radar early. With the cold front having moves all but east of the Ozarks, morning lows were in the lower to middle 60s with a few locations in the upper 50s.
Today is expected to be mainly dry across the region as an upper level jet moves towards the region. This should be enough to allow showers and storms to develop late tonight into Saturday morning in the form of and MCS that develops on the jet in eastern Kansas and moves into Western Missouri and the Ozarks Saturday morning. The addition of warm air advection, some isentropic ascent and low level jet nosing into the region should allow the storms to last into the morning hours an bring a fair chance for rain and storms. It may be possible with the dynamics of the system to see a few strong storms and an isolated severe storm may be possible. Depending on how the early morning system behaves will likely determine the evolution of the storms through the day Saturday.

.LONG TERM /SATURDAY THROUGH THURSDAY/... Issued at 249 AM CDT Fri Sep 19 2025
With cold air advection ongoing behind the cold front, generally seasonable temperatures are forecast today, through the weekend and into early next week as additional rounds of cool air round the base of the upper level trough over the northern plains into the Ozarks. There is good agreement with the models lingering a trough across the northern plains and into northern Missouri through the weekend. Any bit of energy that rounds the base of the trough would be able to produce showers or storms as a result.
There remains uncertainty in the ensembles which may have an impact of location, duration and timing of rainfall going through the weekend and into next week. With the breadth of differing members, rain chances have remained from 30-50% chance Monday through Thursday. Deterministic models suggest instability will be present at least through Wednesday, so thunderstorms can be expected with any rainy day.
The upper trough and associated low do lift to the northeast early next6 week, only to be replaced by another upper level low and troughing over the plains and continued rain chances by the middle of the week. Overall, with multiple rain chances, cool surface flow and cloud cover the potential is there for slightly cooler than normal conditions for next week.
Hopefully, the region will see a relatively uniform rain that will help with the ongoing flash drought that has developed across the Ozarks over the past 30-60 days.
