1255 AM CST THU DEC 18 2025
VALID 191200Z - 201200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
THUNDERSTORMS MAY OCCUR OVER THE MID ATLANTIC AND NORTHEAST EARLY
FRIDAY, AND IN THE PACIFIC NORTHWEST FRIDAY AFTERNOON THROUGH FRIDAY
NIGHT.
..DISCUSSION
A LINE OF THUNDERSTORMS IS EXPECTED ALONG A STRONG COLD FRONT
EXTENDING FROM EASTERN NEW YORK TO EASTERN NORTH CAROLINA FRIDAY
MORNING. THIS LINE OF STORMS IS EXPECTED TO BE MOSTLY ELEVATED FROM
PENNSYLVANIA NORTHWARD. FROM NORTHERN VIRGINIA SOUTHWARD, SOME WEAK
INSTABILITY IS POSSIBLE AHEAD OF THE FRONT AS UPPER 50S TO NEAR 60S
DEWPOINTS ADVECT NORTHWARD. FORCING WILL BE WEAKER FARTHER SOUTH,
AND 00Z CAM GUIDANCE SUPPORTS THIS WITH A MORE BROKEN LINE OF STORMS
THAT FAR SOUTH. IF A MORE CONSOLIDATED, STRONG FRONTAL BAND CAN
CONTINUE WHERE THE NEAR 60S DEWPOINTS ARE PRESENT, A FEW ISOLATED
STRONG WIND GUSTS MAY OCCUR FOR A FEW HOURS IN THE MORNING BEFORE
THE FRONT MOVES OFFSHORE.
IN THE WAKE OF THIS FRONT, BENIGN CONDITIONS ARE EXPECTED ACROSS
MOST OF THE CONUS ON FRIDAY. SCATTERED THUNDERSTORMS ARE POSSIBLE
ACROSS WESTERN WASHINGTON AND FAR NORTHWEST OREGON, BUT THIS
THUNDERSTORM ACTIVITY SHOULD REMAIN WEAK.
