With partly to mostly sunny skies, today’s temperatures have been determined by how much snow is on the ground. In Sioux Falls and SE KELOLAND – where there is little snow cover – temperatures have been well into the 60s. In central and NE South Dakota – where there is a thick snow cover – temperatures have only been in the 40s.
Tonight we will have mostly cloudy skies. There could be some light showers in southern KELOLAND, but they will be very light. Winds will be around 5 mph, and overnight lows will be in the upper 20s to upper 30s, with the coolest temperatures found where the remaining snow cover is thickest.
Tomorrow will be partly cloudy, though clouds will be thickest in central and northern KELOLAND. Sioux Falls and SE KELOLAND will be in the low 60s, while the rest of KELOLAND will be in the 50s, melting more snow. With a low pressure system approaching from the west, Rapid City and western SD could see some thundershowers. Winds across the area will be less than 15 mph.
We expect cloudy skies with widespread rainfall on Wednesday. The rain will be heaviest in southern KELOLAND. We had been concerned about very heavy rainfall in Sioux Falls and the SE, but today’s forecast models have ben lighter with the rainfall amounts (1/2”), and pushed the higher amounts (over 1”) into northern Iowa. We will have a northerly breeze, so highs will drop back below normal in the upper 40s to mid 50s. Rapid City will be windier, with the possibility of some snowflakes mixed in with the rainfall there.
Thursday looks breezy across the area with lingering rain showers, mostly in the morning. Temperatures will be in the 50s.
We expect sunshine and warmer temperatures on Friday, as we begin what looks like a warm holiday weekend. Friday’s highs will be around 60 in the east to the mid 60s in the west, with considerable melting of snow.
Saturday will be mostly sunny and dry, with highs in the mid 60s East River to the low 70s in the west. Rain showers will be possible late in the day in western South Dakota. Easter Sunday will bring a chance of rain across KELOLAND, but temperatures will be mild, in the low to mid 60s. It will be a little cooler on Monday, with a continuing chance of rain (rain/snow mix in western South Dakota).
As far as next week is concerned, it looks like temperatures will be near-normal in the low 60s most of next week into the last weekend of April. Other than early week snowfall in western SD, we really don’t see much chance of snowfall any time in the next couple weeks.
