.DISCUSSION... Issued at 221 PM CDT Sun Sep 14 2025
Upper-level ridging will linger across the Quad State area through at least the middle of the week as a trough digs in across the northern and central Plains. This will keep temperatures well above normal through much of that time period. In fact, it looks like low to mid 90s will be the rule through Wednesday and possibly into Thursday. That is pushing close to 10 degrees above normal. For comparison, normal highs across the area are in the low to mid 80s for this time of year. PWATs/moisture is near normal with dewpoints in the 60s, so heat index values are expected to be fairly close to the actual temperature. Not that it helps much as it is still HOT!!
A few showers and storms are possible (15-20% chance) this afternoon and again Monday afternoon. The greatest focus will likely be over SEMO, far southern IL and far western KY. Otherwise, the next best chance for showers and storms will arrive Friday into Saturday as the aforementioned trough begins to dig farther southeast into the Quad State area. At the same time, a couple frontal boundaries are expected to approach or move through the area, bringing a better chance of showers and storms. Shear and instability doesn`t look overly impressive at this time, but it is worth keeping an eye on over the next few days. Behind, the frontal boundaries and with the trough overhead Friday into Saturday, temperatures are expected to pull back to near normal or right around the mid 80s.
