.DISCUSSION...

WIND GUSTS WILL CONTINUE FOR THE NEXT COUPLE DAYS AS LOW PRESSURE
OVER EASTERN WYOMING CONTINUES TO DEEPEN. THE ASSOCIATED WARM FRONT
STILL EXTENDS EASTWARD ACROSS CENTRAL SOUTH DAKOTA...WHICH IS
KEEPING SITE WINDS EASTERLY. GUSTS WILL CONTINUE TO MAKE WIND SPEEDS
VARIABLE THROUGH TOMORROW. AS THE LOW BEGINS TO LIFT INTO EASTERN
MONTANA TOMORROW...THE WARM FRONT WILL ALSO BEGIN A NORTHWARD TREK
THROUGH NORTH DAKOTA.

THERE IS A SLIGHT CHANCE OF WETTING RAIN ALL DAY...WHICH INCREASES
TO A CHANCE THIS EVENING AND LIKELY TUESDAY. THERE IS INSTABILITY
PRESENT...SO THUNDERSTORMS ARE ALSO A POSSIBILITY. WIND SHIFTS WILL
BE A PROBLEM WITH ANY PRECIPITATION THAT PASSES OVER THE
AREA...SINCE WINDS ALOFT ARE SOUTHWESTERLY AND COULD BE MIXED DOWN
TO THE SURFACE BY DOWNDRAFTS. THERE IS A RISK OF SEVERE WEATHER
TONIGHT AND TOMORROW...SO HAIL AND WIND GUSTS OVER 57 MPH ARE
POSSIBLE WITH CONVECTION THAT PASSES OVER THE SITE THIS EVENING AND
TONIGHT.
