Look for more sunshine across KELOLAND, but temperatures will remain chilly in the mid to upper 40s in most areas.
The chilly weather trend will continue Thursday night, but much warmer weather is coming Friday. It will be interesting to see how fast the mercury rises in western SD, with raw numbers suggesting upper 60s in Rapid City. It looks like low to mid 60s would be a safe bet on highs in both Pierre and Rapid City. Sioux Falls and Aberdeen will be a little cooler, but highs should still be in the mid to upper 50s.
The weekend will start cooler as a cold front arrives Friday night. This will trim highs back into the 40s across the east, with 50s possible again West River. The cooler trend will be replaced by another warm-up by Sunday, with highs returning to the 50s and 60s again - pretty similar to Friday.
A storm system will begin impacting KELOLAND on Monday with cooler weather and areas of rain and snow. Thursday morning’s new data suggests this storm will come into KELOLAND in two pieces. The first wave moves in Monday/Tuesday with areas of rain and snow.
Then, the parent low pressure system will pull out of the Rockies on Thursday. At first glance, it looks warm enough for rain, but the strength of this storm will need to be watched as Gulf of Mexico moisture interacts with this storm. More details will be coming out in the days ahead.
