LIGHT RETURNS ON RADAR TO THE NORTHWEST OVER SOUTHEAST NEBRASKA THIS
MORNING WILL RESULT IN A CHANCE FOR A FEW SPRINKLES DURING THE
MORNING COMMUTES MAINLY NORTH OF HWY-36. MINIMAL IMPACTS ARE
EXPECTED. AS WE ADVECT WARMER TEMPERATURES FROM THE SOUTHWEST AT
H850, HIGHS FOR TODAY ARE EXPECTED TO RANGE IN THE UPPER 70S TO LOW
80S WHICH KEEPS US A FEW DEGREES ABOVE NORMAL FOR THIS TIME OF YEAR.
THIS EVENING, A 25-35 KT LOW-LEVEL JET SETS UP INCREASING MOISTURE
TRANSPORT. A SERIES OF SHORTWAVES MOVING THROUGH THE AREA WILL
RESULT IN A CHANCE FOR SHOWERS AND STORMS TONIGHT INTO EARLY
WEDNESDAY MORNING MAINLY FOR EASTERN KANSAS/WESTERN MISSOURI. STORMS
ARE EXPECTED TO DEVELOP IN CENTRAL TO EASTERN KANSAS AND MOVE EAST
INTO MISSOURI. THE POTENTIAL FOR A FEW STORMS TO BECOME STRONG TO
MARGINALLY SEVERE EXISTS GIVEN THE ENVIRONMENT. BULK SHEAR
VALUES RANGE FROM 30-40 KTS AND MUCAPE VALUES RANGE FROM
500-1000 J/KG. THE MAIN HAZARDS LOOK TO BE STRONG TO DAMAGING
WINDS AND HAIL. SPC HAS PLACED MAJORITY OF OUR AREA IN A
MARGINAL RISK. A CAP IN PLACE OVER MISSOURI COULD INHIBIT
CONVECTION AS STORMS MOVE FARTHER EAST. DETERMINISTIC MODELS
DISAGREE ON TIMING YIELDING SOME UNCERTAINTY IN THE FORECAST.
THE NAM PUSHES THE TIMING FARTHER BACK TO LATE WEDNESDAY
MORNING/AFTERNOON WHILE THE GFS BRINGS IN THE BRUNT OF THE
STORMS OVERNIGHT TUESDAY INTO WEDNESDAY. MODELS SEEM TO DISAGREE
DUE TO UNCERTAINTY OF WHICH SHORTWAVE WILL RESULT IN
CONVECTION.
MULTIPLE SHORTWAVES MOVE THROUGH THE AREA FOR THE SECOND HALF OF
THIS WEEK. DAILY RAIN CHANCES REMAIN WEDNESDAY THROUGH SUNDAY. BULK
SHEAR VALUES AND CAPE VALUES STAY UNIMPRESSIVE THROUGH THE THIS
TIMEFRAME THEREFORE, NO SEVERE WEATHER IS EXPECTED AT THIS TIME.

BEEN PLACED IN A SLIGHT RISK FOR EXCESSIVE RAINFALL. A LINE FROM
PILOT GROVE TO SHERIDAN AND WEST HAS BEEN PLACED IN A MARGINAL RISK
FOR EXCESSIVE RAINFALL.
A SHORTWAVE EJECTING FROM A MID TO UPPER-LEVEL LOW IN THE WESTERN
U.S. WILL RESULT IN A SURFACE TROUGH DEVELOPING ALONG THE EASTERN
ROCKIES. AHEAD OF THE DEVELOPING LOW, INCREASING SHEAR AND
INSTABILITY WILL YIELD THE CHANCES FOR SEVERE WEATHER ON MONDAY. SPC
HAS PLACED OUR AREA IN A SLIGHT RISK FOR SEVERE WEATHER FOR
MONDAY.
