This morning's upper level map shows westerly flow aloft ahead of a trough that is now pushing onto the California Coast. At the surface, a weak trough of low pressure (maybe a warm front) runs north-south through eastern-central SD. Southerly winds with temperatures in the 40s are found east of the trough while westerly winds with temperatures in the 50s/60s are found west of the trough. Skies are mostly clear to partly cloudy across the state.

Today will likely be the warmest day yet this across across SD. High temperatures will be in the 50s/60s over northeastern SD with mid 60s to mid 70s over the rest of the state. Breezy westerly winds will develop statewide by this afternoon with gusts in the 30-50 mph range over western SD. Conditions will also be dry as minimum humidities will drop to the 18-25% range over southern/western SD with 30-60% values elsewhere. This has led to the Grassland Fire Danger Index to be in the Very High to Extreme categories over most of West River and southern parts of the state. Skies will remain mostly clear.

A weak low pressure system and cold front will move through the state from the north overnight tonight. This will lead to cooler temperatures tomorrow. Highs will be in the 40s over northern SD, 50s over western SD, and a mix of 50-60s over southeastern SD. Minimum RHs will range from 20-30% south of I-90 with values above that north of the interstate. Clouds will filter into the state from the north throughout the day. Northwest winds from 10-20 mph with gusts to 25 mph can be expected.
