keeping quiet weather across the Dakotas. Warm air advection
continues today, with temperatures reaching the 40s to mid 50s. The
warmest temps are across the eastern foothills of the Black Hills
and also across south central SD. KUDX radar does show some returns
across northwest SD, but area webcams/obs show this is virga with
the dry boundary layer/15-20F degree dewpoint spreads. Skies will
clear out tonight as the wave pushes east. Lows will be in the 20s
to mid 30s. Warmer air will continue to advect into the region
Sunday, bringing very warm highs in the 50s to mid 60s. Continued

a few morning rain showers to the area. It will also bring gusty NW
