.DISCUSSION... Issued at 144 PM CDT Mon Sep 15 2025
Upper-level ridging will linger across the Quad State area through at least Wednesday as a trough digs across the northern and central Plains. This will keep temperatures well above normal. High temperatures are forecast to be in the low to mid 90s through Wednesday and possibly into Thursday. That will be pushing close to 10 degrees above normal. "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.
A few showers and storms are possible (15-20% chance) this afternoon into this evening, mainly across SEMO. 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 and the ridging pattern begins to break down. At the same time, a couple frontal boundaries are expected to approach the Quad State area, bringing a better chance of showers and storms. Shear and instability both fairly low at this time, but it is worth keeping an eye on over the next few days. Behind/near 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. Precipitation totals aren`t overly impressive (less than 0.5 inches for most locations), so this is not expected to be a drought buster.
