Storm Center Update- Thursday AM

Sioux Falls, SD

Rain continues to track across parts of KELOLAND.  Rainfall amounts have been beneficial for some, with over 1” in Aberdeen and Rapid City.  Pierre, however, has just reported a few hundredths on an inch.  Sioux Falls has had about .25” as of 5am, but more rain is on radar and we’ll include chances of redeveloping showers and scattered t-storms, mainly east of I-29. 


Highs will be near 70 in Sioux Falls, but 50s are likely in both Pierre and Rapid City.  Aberdeen will be in between, likely in the lower to middle 60s.


The air will stabilize tonight and tomorrow and chances of rain will go down.  Temperatures tomorrow will be in the 60s in most areas.

The next big weather story will be the weekend storm system.  Rain will develop on Saturday in western KELOLAND as temperatures fall through the 40s.  There is a good chance that this rain will mix with and change to snow Saturday night and Sunday in the west. 

Rain is likely on Sunday.  However, heavy snow is becoming more likely for parts of the west, especially the Black Hills.  How much snow will be possible?  Stay tuned for more on that later today and tomorrow because there will be a substantial amount of moisture moving into the west with at least 1-2” of water equivalent. 

Thunderstorms in the southeast could turn severe Sunday afternoon if the low pressure track lifts across NW IA.  It’s too early to call the exact track right now, but upper 70s and 80s are possible just south of the low, with 50s just behind it.  Needless to say, that makes Sunday’s forecast very difficult.  Stay tuned for more details on the forecast later today.
