...DISCUSSION...

A LARGE AREA OF CP HIGH PRESSURE WILL MOVE THROUGH THE ERN U.S.
TUESDAY WHILE A LEE TROUGH DEVELOPS ACROSS THE PLAINS. INCREASING
SLY LOW-LEVEL WINDS ASSOCIATED WITH THE LEE TROUGH WILL CONTRIBUTE
TO LIMITED MOISTURE RETURN THROUGH A PORTION OF THE SRN PLAINS.
MODELS INDICATE A LOW AMPLITUDE SHORTWAVE TROUGH WILL MOVE THROUGH
THE CNTRL PLAINS AND MID MS VALLEY REGION TUESDAY NIGHT ACCOMPANIED
BY STEEP 700-500 MB LAPSE RATES. SOME MID-LEVEL CONVECTION MAY
DEVELOP IN ASSOCIATION WITH THIS FEATURE OVER THE MID-MS VALLEY
REGION WHERE INSTABILITY MAY BECOME SUFFICIENT FOR A FEW LIGHTNING
STRIKES. OTHERWISE...THUNDERSTORM POTENTIAL WILL REMAIN LOW THIS
PERIOD.
