VALID 121200Z - 131200Z.

...NO TSTM AREAS FORECAST...

STRONG SHORTWAVE TROUGH...WITH VERY STRONG AND DEEP LAYER WIND
FIELDS...IS FORECAST TO BE LOCATED IN THE UPPER MIDWEST SUNDAY
MORNING. THIS SYSTEM WILL TRANSLATE EWD FROM THE GREAT LAKES INTO
THE NERN STATES AND AMPLIFY THE LONGWAVE TROUGH ACROSS THE NERN
QUARTER OF THE NATION. AN INTENSE SURFACE CYCLONE WILL ACCOMPANY THE
UPPER TROUGH EWD ACROSS FAR SRN ONTARIO ON SUNDAY. A TRAILING COLD
FRONT SHOULD STRETCH FROM THE SURFACE LOW SWWD INTO LOWER MI ACROSS
THE LOWER OHIO/MID MS VALLEYS AND INTO CENTRAL TX BY SUNDAY EVENING.
ALTHOUGH 30 TO 60 MPH WINDS ARE EXPECTED BEHIND AND AHEAD OF THE
FRONTAL PASSAGE IN THE GREAT LAKES AREA...A DRY AIR MASS AND VEERING
WINDS AHEAD OF THE FRONT SHOULD PRECLUDE ANY THUNDERSTORM
DEVELOPMENT. LOW LEVEL LAPSE RATES WILL STEEPEN BEHIND THE FRONT
...WITH LAKE EFFECT SNOW LIKELY TO DEVELOP/INTENSIFY. HOWEVER...
FORECAST SOUNDINGS DO NOT INDICATE SUFFICIENT VERTICAL DEPTH FOR
MORE THAN AN ISOLATED LIGHTNING STRIKE OR TWO.

CONVERGENCE WILL BE STRONGER ALONG THE SEWD MOVING FRONT FROM SRN TX
INTO SRN LA SUNDAY NIGHT AS LOW LEVEL SLY FLOW STRENGTHENS.
DEWPOINTS IN THE UPPER 50S MAY SPREAD INLAND AHEAD OF THE FRONT
ACROSS SRN TX/LA...BUT SHALLOW BOUNDARY LAYER MOISTURE AND WARM
TEMPERATURES BETWEEN 850 AND 600 MB SHOULD INHIBIT CONVECTIVE
DEVELOPMENT.
