DISCUSSION

Issued at 211 PM CDT Wed May 20 2026

High pressure is situated overhead this afternoon with light and variable winds and temperatures in the upper 50s. Fair weather Cu are spread across the region with some high clouds moving up from the southwest. These clouds will continue to increase through this evening as the high moves over the Great Lakes, but we will remain dry through tomorrow. Our rain chances increase Friday as a trough approaches from the west and slowly pivots across the Dakotas and Minnesota through Saturday before lifting north. With virtually no instability to work with, thunderstorms are not expected. Rainfall amounts over the 48 hour period are highest over western Minnesota, with QPF totals around 0.10 to 0.20". Amounts drop off quickly to the east with only a few hundredths possible. This means that the start of the Memorial Day weekend will likely not be a complete washout, but scattered showers and continued temperatures in the low to mid 60s will not feel very summer-like.

The second half of the weekend will see temperatures increase to near normal to above normal by Monday. Ridging sets up over the Central CONUS and remains in place through the end of the forecast period. Temperatures will go from 10-15 degrees below normal this week to 10-15 degrees above normal next week. Humidity will also be on the increase with prolonged southerly flow. There are some low chances for showers and thunderstorms throughout next week, but any widespread rainfall or severe weather is not anticipated at this time.
