.DISCUSSION...
AN AREA OF LOW PRESSURE OVER WESTERN SOUTH DAKOTA WILL CONTINUE TO
WRAP MOISTURE AROUND TO CAUSE ADDITIONAL SNOWFALL OVER THE RESCUE
SITE. PERIODS OF MODERATE SNOWFALL WILL BE POSSIBLE THROUGH THE
AFTERNOON HOURS...THOUGH LIGHT SNOWFALL WILL BE MORE COMMON.
GUSTY WEST WIND WILL REMAIN AROUND THE RESCUE SITE THROUGH THE
AFTERNOON HOURS. VISIBILITIES WILL BE REDUCED OVER THE RESCUE
SITE DUE TO THE COMBINATION OF SNOWFALL AND GUSTY WIND. DURING

ENOUGH EAST THAT ITS MOISTURE WILL NO LONGER IMPACT THE RESCUE
SITE. PRECIPITATION AND WIND CONDITIONS WILL STEADILY IMPROVE THIS
AFTERNOON AND EVENING. RELATIVELY BENIGN CONDITIONS WILL BE FOUND
