Forecast
KELO_skycam_RAP_may26

BIG PICTURE:
Persistent upper level high pressure over the Gulf of Mexico and upper level low pressure over the west coast will keep the stormy pattern over the central US for a few more days. More rounds of severe weather are expected in the central US with the strongest storms south of KELOLAND today through early this week. And while today has been mostly sunny, this afternoon and tonight we’ll need to bring the rain and storms back into the forecast.

LOCAL FORECAST:

A sunny sky was found over most of KELOLAND today as afternoon temperatures warmed to the 70s. Storm cells have already started popping up in western SD and these storms will continue through tonight as they travel from west to east. Some thunderstorms could be severe with hail being the main threat.

And because we are expecting several days of moderate to heavy rainfall, there is good potential for more flooding. A flood watch will go into effect this evening for western SD.

After the morning showers and thunderstorms clear out, Monday will have lingering clouds and scattered showers in the afternoon. Some thunderstorm redevelopment is possible in the southeast during the heat of the day. Afternoon highs will be a little cooler. The southeast will reach the upper 60s to low 70s, central and northeast KELOLAND will reach the lower to mid 60s, and the west will be stuck in the 50s.

Tuesday will continue the rain chances as another surface low pressure slides through Nebraska. Some thunderstorms are possible in the southeast again, because they’ll be in the warm sector of the low for a short time, but the rest of KELOLAND is looking at rain showers. Highs on Tuesday will be in the 50s to 60s.

The rest of the week looks dry once the rain exits southeast KELOLAND around midday on Wednesday. Then we are looking at partly cloudy skies and highs returning to the 70s. Friday looks especially warm with highs getting close to 80 degrees.
