Storm Center Update- Monday AM

Sioux Falls, SD

Another mild week is ahead for KELOLAND along with chances of rain, some possibly heavy.  First, the forecast looks dry today and well above normal.  We should see most areas into the 80s, with highs close to 90 in Pierre.  South winds will be breezy in Sioux Falls at 15-25 with lower 80s likely.

A cold front will cross through KELOLAND tonight, but chances of rain will stay in the southeast.  Overnight lows will still hover in the lower 60s in Sioux Falls, but 50s are more likely to the west.

Cooler weather is forecast tomorrow, but we will still have 70s in most areas with east winds.  The challenge tomorrow and Wednesday will be developing chances of rain.  Initially, chances of showers and storms will be higher in the east and northeast tomorrow night.

Thunderstorms are more likely late Wednesday into Thursday as we follow the tropical moisture plume streaming in from the southwest.  There are still a number a questions surrounding the exact placement of the heaviest rainfall, but a stalled boundary should focus the threat of heavy rain from central Nebraska into eastern SD.  Some amounts could top 2” by Thursday, but again, we have plenty of time to watch the details.

Temperatures will hold in the 70s much of the week, but warmer weather is around the corner by Saturday and Sunday with 80s returning.  By the way, we’ll likely finish the month above normal early next week.  No sign of autumn weather just yet!
