DISCUSSION

Issued at 141 AM CDT Fri May 22 2026

Looks like we will have an break tonight in terms of MCS party! Convection is tapering off to the north of the region as of midnight, though some showers will likely clip the Victoria Crossroads region. Friday's rain chances will be relatively low across the region as shortwaves continue to track through the area (>40%).

Saturday, a more potent disturbance will move through the region and combine with above normal PWATs (2.0+ inches). This will lead to another round of widespread heavy rainfall. Efficient rainfall rates due to the environment over already saturated soils will likely lead to flooding. As previously mentioned, we have seen about 3-6 inches of rain over the past few days and Saturday we can expect around 2-4 inches with locally higher amounts. The area will remain in a Flood Watch until Monday. Will continue to monitor the trends but as it sits the area remains in a slight risk for excessive rainfall Saturday. There is still a possibility we could see an upgrade in the next few cycles therefore check back for future updates. The message will remain the same however, the area will be more susceptible to flooding and river flooding. It is encouraged to take the necessary precautions and to also not drive through flood waters.

Otherwise, our next chance of rain will likely be around the middle of next week. Will monitor this closely as it could cause further flooding concerns given already saturated soils. Temperatures will be in the 80s through the end of next week.
