KEY MESSAGES
- Period of rain tonight into Tuesday morning for southeast North Dakota into Minnesota. Heaviest precipitation is likely to stay southeast of a Valley City to Red Lakes line.
- A brief mix or change to wet snow overnight for parts of the area, but light precipitation rates and warm ground should inhibit accumulation.
- Seasonable high temperatures in the 40s and 50s through midweek, turning slightly warmer by the weekend.
..Rain Tonight into Tuesday
A stronger mid level wave is organizing into a hybrid type system with large scale ascent increasing across our CWA south to north late this afternoon through Tuesday. Initially drier air in northeast boundary layer flow will delay measurable rainfall, deeper moisture will support 700mb deformation banding of rainfall across the southern zones tonight. Stronger areas of frontogenesis will tend to be transient making coverage of higher totals 0.5"+ limited. Better coverage of rain will tend to initially be along and south of US Highway 200, though the track of the mid/upper low will eventually allow rain to overspread northwest/north central MN. Moderate to high probabilities (50-80%) for 0.25" or more rainfall are shown by NBM/HREF across southeast ND and west central MN, with a 30-50% chance in similar areas for greater than 0.5" of rainfall. Temperatures and precipitation rates tonight overall do not support any accumulating snowfall, just novelty flakes mixing in. If sufficient banding and dynamic cooling occurs, a light dusting on grassy/elevated surfaces cannot be ruled out (especially west of the Red River Valley).
