...SYNOPSIS...
UPPER LOW NOTED NEAR HUDSON BAY PER WV IMAGERY WILL MOVE SEWD
TODAY...AS SPEED MAX ACCELERATES ACROSS THE UPPER MIDWEST/SRN NEW
ENGLAND. ANOTHER UPPER SYSTEM OFF THE WEST COAST IS FORECAST TO MOVE
EWD ACROSS CA INTO THE GREAT BASIN BY LATE TONIGHT SPREADING PACIFIC
MOISTURE INLAND. HIGH PRESSURE ALOFT WILL DOMINATE THE REST OF THE
INTERMOUNTAIN REGION. AT THE SFC...A COLD FRONT NOW LOCATED FROM
CNTRL NEW ENGLAND INTO THE OH RIVER VALLEY REGION...WILL MOVE
OFFSHORE WHILE THE SRN END OF THE BOUNDARY MOVES SLOWLY SWD ACROSS
THE TX HILL COUNTRY.

...NEW ENGLAND...
THERMODYNAMIC PROFILES LOOK INCREASINGLY FAVORABLE FOR ISOLATED
LIGHTNING STRIKES TODAY ACROSS PORTIONS OF NY/ERN GREAT LAKES. 12Z
BUFFALO SOUNDING SHOWS AN INVERSION ABOVE 700 MB...BUT POINT
FORECAST SOUNDINGS FROM THE RUC/ETA SUGGEST STEEPER LAPSE RATES WILL
DEVELOP WITH RISING INVERSION HEIGHTS. TEMPERATURES ALOFT ARE
CERTAINLY COLD ENOUGH TO SUPPORT LIGHTNING DEVELOPMENT. INCREASING
LARGE SCALE ASCENT COMBINED WITH THE THERMODYNAMIC PROFILES HAS
RESULTED IN THE FORECAST OF GENERAL THUNDER IN THIS REGION.

...SRN TX...
SFC DEWPOINTS ARE IN THE LOW TO MID 60S ACROSS SRN TX...WITH A SFC
BOUNDARY NORTH OF THE AREA. ALTHOUGH SHOWERS CAN BE
EXPECTED...LIGHTNING IS NOT LIKELY GIVEN THE WARM AIR ALOFT NOTED ON
THE 12Z CRP SOUNDING.
