506 FNUS73 KFSD 141149 FWSFSD Spot Forecast for Little Swan WMA...MN DNR National Weather Service Sioux Falls SD 649 AM CDT Tue May 14 2024 If conditions become unrepresentative, contact the National Weather Service. .DISCUSSION... Light east-northeasterly winds will result in poor smoke dispersion this morning. However, once winds increase to 10 to 15 mph this afternoon, should see smoke dispersion quickly improve. High res models continue to indicate that Canadian wildfire smoke will linger aloft through the evening, with impacts at the surface expected to remain minimal. Afternoon temperatures will climb into the lower 70s with dew points in the 40s, resulting in afternoon RH values near 35 percent. Otherwise, expect chances for showers and storms to return late tonight through Wednesday as a frontal boundary slowly moves across the area. Southerly winds of 10-15 mph on Wednesday morning will transition to northwesterly by afternoon with the passage of the boundary. .REST OF TODAY... Max temperature.....Around 72.
