DISCUSSION
COLD FRONT STRETCHED FROM EXTREME EASTERN SOUTH DAKOTA THROUGH
EASTERN NEBRASKA INTO WESTERN KANSAS AT 08Z. AREA OF PRECIP WAS
LOCATED ON THE BACK SIDE OF THE FRONT FROM WESTERN NEBRASKA INTO
EASTERN SOUTH DAKOTA. MODELS FAIRLY SIMILAR IN TAKING FRONT SLOWLY
EAST TODAY WITH POST FRONTAL PRECIP ENDING AND MAIN FOCUS SHIFTING
TO AREA AHEAD OF THE FRONT WHERE BETTER MOISTURE INDICATED FOR
PRECIP DEVELOPMENT. WILL CONTINUE TO CARRY SOME LOW POPS THROUGH THE
MORNING ACROSS THE CWA THEN DROP WEST TO EAST AS FRONT PROGRESSES
INTO THE BETTER MOISTURE THIS AFTERNOON AND TONIGHT. HIGH PRESSURE
BUILDS INTO THE AREA TONIGHT AND WEDNESDAY WITH DRY WEATHER
ACROSS THE AREA. PATTERN BECOMES MORE COMPLEX FOR THE REMAINDER OF
THE SHORT TERM AS SEVERAL PIECES OF SHORT WAVE ENERGY MOVE ACROSS
THE REGION AS FLOW SPLITS AND SOUTHERN TROUGH BECOMES MORE ELONGATED
OVER THE SOUTHWEST. CURRENT MODELS KEEP BETTER MOISTURE SOUTH OF THE
AREA ON THURSDAY BUT WITH THE MOISTURE NEARBY AND UNCERTAINTY IN
SHORT WAVE TIMING WILL CONTINUE TO HOLD SOME LOW POPS OVER THE AREA
FOR NOW. NO CHANGE IN THE EXTENDED PORTION OF THE FORECAST AT THIS
TIME.
