DISCUSSION
Issued at 1222 AM CDT Sat Oct 17 2026
As expected conditions are sharply cooler tonight across the quad-state. Moderate northwest winds should continue overnight with temperatures falling into the 40s area-wide. A 1040mb surface ridge sits over the western Plains with plans of sitting overtop of this region tonight. With plenty of drier air being pushed in with this ridge, idealized radiational cooling conditions amid deep layer ridging, and calm winds under the ridge axis very strong radiational cooling conditions are expected. Frost still looks likely enough area-wide to go with an advisory. Some areas particularly in the northern half of the region could very well drop to freezing as things bottom out.
Good model consensus that the upper level pattern gets blocked up for several days as we head into the new work week. With ridging over the plains leading to surface ridging focused just east of the area. Dry conditions with low humidity and seasonable temperatures look likely for several days amid a stable/settled pattern. Highs in the low to mid 70s and lows in the mid to upper 40s are projected, which is right in line with seasonal norms.
A few Pacific troughs will take a shot at dislodging the ridging through the end of the week, but in most all guidance they are unsuccessful and sail well to the north of the region keeping the pattern in place.
