A small but potent shortwave trough is moving through the MN/WI area this morning with westerly flow aloft over the Dakotas. At the surface, high pressure is in place over our region while a weak pressure trough extends from eastern MT southward into eastern WY. The surface high pressure is really dictated wind direction as the pressure center is over central SD--this implies northwesterly winds over eastern SD and southeasterly winds over western SD. Temperatures this morning are in the 50s over the Black Hills and 60s elsewhere across the state. Skies are mostly clear except for some cloud cover near the MN border and across southwestern portions of SD.

High pressure will slowly move east with time today leading to light and variable winds over eastern SD with southerly winds picking up over much of western SD. The aforementioned pressure trough is expected to move into at least northwestern parts of the state this afternoon bringing some breezy northwest winds there later today. High temperatures will range from the upper 70s across far eastern SD to the mid/upper 80s over western SD. Mid- to upper 70s will be seen across the Black Hills. Minimum RHs will drop into the 20-30% range over most of West River with 30-45% values over East River. There is a Red Flag Warning in effect for Harding County today but conditions are not as critical as that warning implies. It will be a borderline Red Flag day there at best. A few showers and thunderstorms will likely pop up along and ahead of the front. Heavy precipitation is not expected but a few strong winds gusts are possible.

That trough will push through the state tonight leading to northwest winds from 10-20 mph tomorrow. Like today, minimum RHs will drop into the 18-30% range over western SD, driest across southwestern parts of the state. Eastern SD will again see RHs from 30-45%. High temperatures will be similar to today as well ranging from near 80 over the far eastern reaches of SD to the upper 80s over western SD. Mostly clear skies are expected.
