We are starting Sunday with leftover sprinkles in eastern and southeastern KELOLAND. But that should clear out this morning, leaving behind dry skies for the afternoon. Western KELOLAND has already begun to see the next round of light rain move in from the west and that will continue to move west throughout the day today. With a light northerly breeze, we will have afternoon temps in the 50s to lower 60s.
The clouds and light rain that will move in from the west today will linger around tonight. Temperatures will bottom out in the 30s to lower 40s.
Continued incoming cooler air on Monday means even cooler afternoon highs, only reaching the 40s to 50s under a cloudy to mostly cloudy sky. And the chances for scattered light rain continues on Monday as well.
The weather pattern changes a bit on Tuesday. We’ll still be cool and cloudy but an area of low pressure will move through the Midwest and it’s going to bring some showers and thunderstorms to the central US. Severe weather and flooding is likely to our south but because we will stay on the north side of the low, we are looking at a broad area of rain to move through.
It looks like the rain will begin to move in Tuesday and will last through Wednesday night, exiting most of the area Thursday morning but western SD may still have some lingering precipitation on Thursday. The rain will come from the southwest so the farther north you are in KELOLAND, the later in the day on Tuesday, you’ll see the rain arrive.
Rain amounts will be quite impressive with the most rain falling in the southeast. Right now, computer model rainfall projections give the south-central and southeast regions upwards of one to one and a half inches of rain, the west would see about a half inch to an inch, and the north would see the least amount, at around a quarter to half inch.
Temperatures through this event will be cool for early May, only topping out in the 40s and 50s, cool enough snow would be likely in western SD and the Black Hills. But next Friday and the weekend brings back the warmer 50s to 60s and dry skies.
