VALID 261200Z - 271200Z

...THERE IS A MRGL RISK OF SVR TSTMS ACROSS ERN WY...WRN SD AND WRN
NEB...

...SUMMARY...
A FEW MARGINALLY SEVERE STORMS ARE EXPECTED ACROSS THE NORTHERN HIGH
PLAINS...WITH A LARGE AREA OF GENERAL THUNDERSTORMS FROM THE ROCKIES
INTO THE MID MISSISSIPPI AND OHIO VALLEYS. A STRONG STORM OR TWO
WITH WIND MAY OCCUR ACROSS MAINE AS WELL.

...SYNOPSIS...
A BROAD UPPER TROUGH WILL MOVE QUICKLY ACROSS ERN CANADA WITH BASE
OF THE TROUGH AFFECTING NEW ENGLAND WITH STRONG WINDS ALOFT. A LOW
PRESSURE TROUGH WILL ALSO MOVE ACROSS MAINE DURING THE DAY...AND MAY
FOCUS A FEW THUNDERSTORMS. MEANWHILE...AN UPPER HIGH WILL REMAIN
SITUATED OVER THE SERN U.S. WITH BUILDING HEIGHTS OVER THE NE.

TO THE W...A BROAD UPPER TROUGH WILL MOVE INTO THE NRN PLAINS WITH
COOL AIR ALOFT AND SOME INCREASE IN WIND SPEEDS. WITH HIGH PRESSURE
CENTERED OVER THE GREAT LAKES...SLY FLOW WILL EVENTUALLY BRING
MOISTURE NWWD TOWARD THE NRN HIGH PLAINS LATE IN THE DAY WHERE A LEE
TROUGH WILL PROVIDE A FOCUS FOR A FEW SEVERE STORMS.

...ERN WY...WRN SD AND WRN NEB...
RELATIVELY COOL TEMPERATURES ALOFT WILL EXIST BENEATH THE UPPER
TROUGH AND HEATING WILL CREATE STEEP LOW LEVEL LAPSE RATES AS WELL
OVER WRN SD/NEB AND ERN WY. HERE...SELY SFC WINDS LIKELY BRING 50S F
DEWPOINTS NWWD TOWARD A WEAK SFC TROUGH BY AFTERNOON...RESULTING IN
AROUND 1000 J/KG MUCAPE. LOW-LEVEL FLOW WILL BE WEAK...BUT GOOD MID
TO UPPER LEVEL FLOW WILL LENGTHEN HODOGRAPHS AND RESULT IN A
FAVORABLE ENVIRONMENT FOR A FEW SPLITTING CELLS CAPABLE OF
MARGINALLY SEVERE HAIL. SOME STORMS WILL PERSIST ACROSS CNTRL SD/NEB
DURING THE EVENING...BUT MOSTLY A RAIN THREAT IS EXPECTED AT THAT
TIME.

...MAINE...
A LOW-AMPLITUDE UPPER TROUGH WILL GRAZE THE AREA WITH SFC TROUGH
MOVING ACROSS NRN NEW ENGLAND DURING THE DAY. INSTABILITY SHOULD BE
SUFFICIENT FOR A FEW STRONG STORMS GIVEN FORCING FOR ASCENT AND
INCREASED MEAN DEEP-LAYER WIND SPEEDS. HOWEVER...MODELS VARY WITH
QPF SIGNAL ACROSS THE AREA AND PREDICTABILITY IS CURRENTLY TOO LOW
TO INTRODUCE A MARGINAL RISK.
