...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE CENTRAL AND NORTHERN PLAINS...
..SUMMARY
THUNDERSTORMS ASSOCIATED WITH A THREAT FOR ISOLATED SEVERE GUSTS AND
HAIL WILL BE POSSIBLE ACROSS PARTS OF THE CENTRAL AND NORTHERN
PLAINS ON TUESDAY.
..CENTRAL AND NORTHERN PLAINS
AT MID-LEVELS, A RIDGE IS FORECAST TO REMAIN OVER THE CENTRAL
ROCKIES ON TUESDAY, AS A SHORTWAVE TROUGH MOVES THROUGH THE NORTHERN
HIGH PLAINS. AT THE SURFACE, A MOIST AIRMASS WILL BE IN PLACE ACROSS
MUCH OF THE NORTH-CENTRAL U.S., WHERE DEWPOINTS ARE FORECAST TO BE
MOSTLY IN THE 60S F. ALONG THE WESTERN EDGE OF THIS MOIST AIRMASS,
AN AXIS OF MODERATE INSTABILITY IS FORECAST TO DEVELOP BY AFTERNOON
FROM WESTERN KANSAS NORTHWARD INTO THE WESTERN DAKOTAS. SCATTERED
THUNDERSTORM ARE EXPECTED TO FORM AHEAD OF THE TROUGH ACROSS THE
NORTHERN PLAINS, WITH MORE ISOLATED DEVELOPMENT OCCURRING SOUTHWARD
INTO THE CENTRAL HIGH PLAINS. NAM FORECAST SOUNDINGS BY LATE
AFTERNOON NEAR THE INSTABILITY AXIS FROM WESTERN NEBRASKA INTO
WESTERN SOUTH DAKOTA HAVE 0-6 KM SHEAR IN THE 30 TO 35 KNOT RANGE,
WITH 700-500 MB LAPSE RATES NEAR 8.5 C/KM. IN ADDITION, SURFACE
TEMPERATURE-DEWPOINT SPREADS ARE FORECAST TO BE NEAR 30 DEGREES F.
THIS THERMODYNAMIC ENVIRONMENT WILL LIKELY RESULT IN HIGH-BASED
CELLS WITH POTENTIAL FOR SEVERE GUSTS. HAIL WILL ALSO BE POSSIBLE,
MAINLY WITH CELLS THAT FORM NEAR AREAS WITH THE STRONGEST
INSTABILITY.
