.SHORT TERM...(TONIGHT THROUGH FRIDAY)

SOUTHEAST SOUTH DAKOTA BY WEDNESDAY MORNING THEN CONTINUE EAST
INTO NORTHEAST IOWA BY WEDNESDAY AFTERNOON. A COLD FRONT WILL
FOLLOW BEHIND THE LOW AND SWEEP ACROSS NEBRASKA AND WESTERN IOWA
DURING THE DAY WEDNESDAY WITH ANOTHER ROUND OF GUSTY NORTHWEST
WINDS MOVING IN BEHIND THE FRONT. MODELS CONTINUE THEIR PREVIOUS
TREND OF KEEPING MOST OF THE PRECIP ON THE NORTH SIDE OF THIS
SYSTEM AS IT MOVES THROUGH THE REGION.

LOOKS MAINLY DRY FOR THE AREA WEDNESDAY NIGHT INTO THURSDAY AS
LATEST SOLUTIONS KEEP SOUTHERN PLAINS SURFACE WAVE AND ASSOCIATED
PRECIP FURTHER SOUTH AS UPPER WAVE AMPLIFIES OVER THE REGION THEN
MOVES RAPIDLY EAST. SOME CHANCE POPS FOR THE AREA ON FRIDAY AS
WARM ADVECTION ZONE DEVELOPS LATE THURSDAY NIGHT INTO FRIDAY
MORNING FROM EASTERN SOUTH DAKOTA INTO EASTERN NEBRASKA AND
WESTERN IOWA. WARMER TEMPERATURES ALSO RETURN TO THE AREA ON
FRIDAY AS RIDGING INCREASES OVER THE PLAINS AHEAD OF THE NEXT
TROUGH MOVING INTO THE WESTERN CONUS.

.LONG TERM...(FRIDAY NIGHT THROUGH TUESDAY)
ISSUED AT 255 PM CDT TUE APR 15 2014
