...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...

AN UPPER RIDGE WILL BUILD OVER THE NRN PLAINS IN WAKE OF SHORTWAVE
TROUGH THAT WILL CONTINUE EWD THROUGH THE GREAT LAKES AND THE NERN
U.S. FRIDAY. A LEE TROUGH WILL BECOME ESTABLISHED OVER THE CNTRL AND
NRN HIGH PLAINS IN WAKE OF RETREATING SURFACE HIGH PRESSURE. FARTHER
WEST A COLD FRONT WILL ACCOMPANY AN UPPER TROUGH INTO THE PACIFIC NW
AND NRN ROCKIES. HIGH PRESSURE ALOFT WILL PREVAIL OVER THE SRN THIRD
OF THE COUNTRY.

...CNTRL THROUGH NRN PLAINS...

LOW LEVEL MOISTURE WITH DEWPOINTS IN THE UPPER 50S TO AROUND 60 WILL
ADVECT NWD THROUGH THE CNTRL AND NRN PLAINS AS SLY FLOW INCREASES IN
GRADIENT ZONE BETWEEN RETREATING HIGH PRESSURE AND DEVELOPING LEE
TROUGH. STEEP MID LEVEL LAPSE RATES WILL EXIST ABOVE THE RETURNING
MOISTURE WITH MODERATE INSTABILITY EXPECTED AS THE BOUNDARY LAYER
WARMS DURING THE AFTERNOON. THE RETURN OF BOUNDARY LAYER MOISTURE
AND INSTABILITY TO THE CNTRL AND NRN PLAINS WILL BE COINCIDENT WITH
RISING HEIGHTS ASSOCIATED WITH THE BUILDING UPPER RIDGE. OTHER THAN
WEAK CONVERGENCE IN THE VICINITY OF THE LEE TROUGH...FORCING FOR
DEEP LAYER ASCENT WILL REMAIN RELATIVELY WEAK DURING THE DAY. GIVEN
THE LIMITED FORCING FOR ASCENT AND BUILDING UPPER RIDGE...ONLY VERY
ISOLATED STORMS AT BEST ARE EXPECTED DURING THE AFTERNOON OVER THE
CNTRL AND NRN HIGH PLAINS. ANY STORMS THAT CAN DEVELOP MAY BE
CAPABLE OF PRODUCING ISOLATED HAIL AND DAMAGING WIND. A BETTER
CHANCE FOR THUNDERSTORM INITIATION MAY COME LATER FRIDAY NIGHT OVER 
THE ERN DAKOTAS INTO MN WHEN WARM ADVECTION ASSOCIATED WITH THE
NOCTURNAL LOW LEVEL JET INCREASES. HAIL WILL BE THE PRIMARY THREAT
WITH THIS ACTIVITY.
