Light rain showers continue to blanket much of western South Dakota. Now a few showers are moving into our south-central counties, in areas like Gregory and Mission. So far, we’ve only had lighter rainfall totals, but it’s been a nasty day of gray skies and strong winds.
The actual center of the upper low is in SW Nebraska but should move into SD tonight. After that happens, we’ll finally see rain moving into eastern South Dakota. Winds remain strong across the region, both ahead of, and behind, the advancing system.
If you’re looking at the radar now, rain certainly seems promising for Sioux Falls. But as the system progresses to the northeast, Sioux Falls and the southeast will be left with only a thin trail of moisture. Aberdeen has a slightly better chance at higher rainfall totals, at least compared to Sioux Falls.
It’s going to take a long time for skies to clear in the west. After they finally do (late tonight), we’ll cool down into the 40s. Most other spots will bottom out in the 50s. Computer models have long shown rain pushing out of SD after daybreak tomorrow. We’ve left a slim chance of rain in for tomorrow morning but MOST of the day should remain dry. Tuesday will be a 180° turn for Rapid City. There will be more sunshine and certainly more warmth. Expect partly cloudy skies for Sioux Falls and Aberdeen by the end of the day. Wednesday and Thursday will be mild and comfortable before we welcome another strong cold front early Friday. This will cool us down about ten degrees and we’ve got a chance of rain through early Saturday.
