Weak upper level ridging is in place this morning over the Great Plains with plenty of monsoonal moisture streaming into the region per this morning's water vapor imagery. The surface map shows a broad area of high pressure over northwestern MN leading to southerly to southeasterly winds across SD. Temperatures this morning are already plenty warm with readings in the 70s and 80s while dewpoints are well into the 60s keeping the warm air plenty humid. Skies are partly cloudy across the state and a few showers are present over southeastern SD.

Warm and humid conditions will continue today with the southeasterly winds. Winds speeds will generally be from 10-20 mph with a few gusts approaching 30 mph over northwestern SD. High temperatures will be in the upper 80s to lower 90s. Minimum RHs will fall into the 25-35% range West River and the 35-50% range East River. Scattered showers and thunderstorms are expected to form over the Black Hills and northwestern SD this afternoon with some severe weather possible. The primary threat will be large hail. More storms are expected to move across the state overnight tonight as a weak frontal boundary crosses the area. 

That boundary will stall over southeastern SD tomorrow. This will bring northwesterly winds to central and western SD and south to southwesterly winds to eastern SD. High temperatures will be in the 90s with some low 100s over central and southeastern portions of SD. Minimum RHs will be similar to today although parts of Fall River and Custer County may see some values below 20%. A few afternoon showers and thunderstorms are likely along the aforementioned boundary over eastern SD
