...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM THE CENTRAL
HIGH PLAINS TO PARTS OF THE CORN BELT...
..SUMMARY
ISOLATED SEVERE THUNDERSTORMS, ACCOMPANIED BY WIND AND HAIL, ARE
POSSIBLE MONDAY AFTERNOON FROM THE CENTRAL HIGH PLAINS TOWARD PARTS
OF THE CORN BELT.
..DISCUSSION
ON MONDAY, A SHORTWAVE TROUGH WILL LIFT NORTHEASTWARD OUT OF THE
NORTHERN PLAINS, WITH AN UPPER HIGH OVER THE MID MS/LOWER OH
VALLEYS. TO THE WEST, AN UPPER LOW WILL DROP SOUTHWARD OFF THE WEST
COAST, WITH INCREASING SOUTHWEST FLOW ALOFT FROM CA INTO THE GREAT
BASIN LATE. A LEADING WAVE IS ALSO FORECAST TO DEVELOP OVER THE
CENTRAL ROCKIES, MOVING FROM CO INTO NE OVERNIGHT.
AT THE SURFACE, A QUASI-STATIONARY BOUNDARY WILL EXTEND FROM NE/SD
INTO SOUTHERN MN/WI, WHERE 60S TO 70S F DEWPOINTS WILL EXIST.
CONDITIONALLY, THIS REGION COULD SUPPORT A SEVERE RISK. HOWEVER, THE
DEPARTING UPPER WAVE COMBINED VEERING AND WEAKENING LOW-LEVEL WINDS
SUGGEST MINIMAL STORM COVERAGE FOR MOST OF THE PERIOD. SOME FORECAST
SOUNDINGS ALSO INDICATE SHALLOW BOUNDARY LAYER MOISTURE. HOWEVER,
ISOLATED STORMS CANNOT BE RULED OUT BOTH DURING THE DAY AND
OVERNIGHT WITHIN THIS MOIST ZONE, THEREFORE WILL MAINTAIN LOW SEVERE
PROBABILITIES.
SCATTERED STRONG TO SEVERE STORMS MAY ALSO OCCUR OVER THE CENTRAL
HIGH PLAINS, WHERE A LEE TROUGH WILL DEVELOP AND WHERE A DEVELOPING
MIDLEVEL WAVE IS FORECAST. STRONG HEATING AS WELL AS 50S TO NEAR 60
F DEWPOINTS WILL SUPPORT SCATTERED LATE AFTERNOON STORMS FROM
EASTERN CO/SOUTHEAST WY, SPREADING NORTHEAST INTO NE. A FEW SEVERE
GUSTS OR MARGINAL HAIL WILL BE POSSIBLE.
