DAY 3 CONVECTIVE OUTLOOK

VALID 071200Z - 081200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
THE RISK FOR THUNDERSTORMS APPEARS NEGLIGIBLE ACROSS MUCH OF THE
U.S. SUNDAY THROUGH SUNDAY NIGHT.
..DISCUSSION
MODELS INDICATE THAT MID/UPPER RIDGING MAY REBUILD OFFSHORE OF THE
BRITISH COLUMBIA AND PACIFIC NORTHWEST COAST, WHILE BEING MAINTAINED
ACROSS AND INLAND OF COASTAL AREAS THROUGH THIS PERIOD. DOWNSTREAM
FLOW MAY NOT CHANGE APPRECIABLY ON THE LARGER-SCALE, BUT ONE BROAD
EMBEDDED CYCLONIC CIRCULATION MAY REDEVELOP SOUTHEAST OF THE
HUDSON/JAMES BAY VICINITY THROUGH CENTRAL QUEBEC, WHILE A
CONSOLIDATING PERTURBATION WITHIN ANOTHER STREAM DIGS ACROSS THE
CENTRAL/SOUTHERN GREAT PLAINS TOWARD THE SOUTHEAST.
THE LATTER FEATURE IS FORECAST TO BE ACCOMPANIED BY A REINFORCING
COLD INTRUSION ACROSS THE GULF COAST INTO NORTHWEST GULF BASIN BY
LATE SUNDAY NIGHT. DOWNSTREAM, A WEAK LOW MAY BEGIN TO DEVELOP
ALONG THE INITIALLY STALLED/SLOW MOVING FRONTAL ZONE, EAST OF THE
FLORIDA PENINSULA.
..FLORIDA
FORECAST SOUNDINGS INDICATE THAT RELATIVELY WARM LAYERS ALOFT WILL
CONTINUE TO HINDER POTENTIAL FOR DEEP CONVECTIVE DEVELOPMENT OVER
THE INTERIOR CENTRAL AND SOUTHERN PENINSULA SUNDAY THROUGH SUNDAY
NIGHT. IN GENERAL, GUIDANCE SUGGESTS THAT BETTER COUPLING OF
MID/UPPER FORCING FOR ASCENT AND HIGHER BOUNDARY-LAYER MOISTURE
CONTENT MAY BE CONFINED TO AREAS ALONG/AHEAD OF THE FRONT ACROSS THE
NORTHEASTERN INTO CENTRAL GULF BASIN AND OFFSHORE WESTERN ATLANTIC.
