SOUTH DAKOTA WEATHER SUMMARY

1155 AM CDT SAT MAY 25 2013

A FAVORABLE PATTERN FOR THUNDERSTORM DEVELOPMENT CONTINUED ACROSS
THE NORTHERN PLAINS OVERNIGHT...WITH THE LOW LEVEL FLOW FROM THE
EAST OR SOUTHEAST...AND THE UPPER LEVEL FLOW OUT OF THE SOUTHWEST.
THIS ALLOWED A CONVECTIVE COMPLEX OF THUNDERSTORMS OVERNIGHT TO
AFFECT MUCH OF NEBRASKA...EASTERN SOUTH DAKOTA...IOWA...AND SOUTHERN
MINNESOTA. CLOUDS ACROSS SOUTH DAKOTA IN THE PAST 18 HOURS WERE
QUITE VARIABLE. HOWEVER...MOST OF THE WEST WAS CLEAR TO PARTLY
CLOUDY DURING THE NIGHT...WITH INCREASING CLOUDS THIS MORNING. THE
EASTERN HALF OF SOUTH DAKOTA WAS CLOUDY FRIDAY EVENING...CLEAR TO
PARTLY CLOUDY SOME OF THE EVENING AND EARLY NIGHT...THEN CLOUDY
AGAIN WITH SCATTERED SHOWERS AND THUNDERSTORMS LATE AT NIGHT AND
EARLY THIS MORNING. SINCE SUNRISE...CLOUDS ACROSS THE EASTERN HALF
OF THE STATE HAVE BEEN GRADUALLY DECREASING FROM WEST TO EAST.

RAINFALL IN SOUTH DAKOTA THE PAST 24 HOURS HAS BEEN MAINLY FOCUSED
ON THE EASTERN THIRD OF THE STATE. AMOUNTS WERE A QUARTER INCH OR
LESS...BUT MORE FELL FURTHER EAST INTO SOUTHWEST MINNESOTA AND
