..NO THUNDERSTORM AREAS FORECAST
..SUMMARY
THUNDERSTORMS APPEAR UNLIKELY FRIDAY.
..SYNOPSIS
MID-LEVEL FLOW OVER THE US WILL CONTINUE TO AMPLIFY AS PERSISTENT
EASTERN TROUGHING IS BOLSTERED BY THE ARRIVAL OF A NORTHERN STREAM
SHORTWAVE FROM CANADA AND A DEEPENING SOUTHERN STREAM WAVE OVER THE
GULF COAST. AS THESE SYSTEMS MERGE, A STRONG UPPER LOW IS EXCEPTED
TO DEVELOP ACROSS THE SOUTHERN US DEEPENING A SURFACE LOW OVER THE
EASTERN GULF AND WESTERN ATLANTIC INTO EARLY SATURDAY. AT THE SAME
TIME, STRONG RIDGING ALOFT WILL BUILD OVER THE WEST SUPPORTING
INCREASINGLY STRONG NORTHWESTERLY FLOW. THIS WILL ALLOW A STRONG
COLD FRONT AND ARCTIC HIGH PRESSURE TO MOVE OUT OF SOUTHERN CANADA
REINFORCING OFFSHORE FLOW OVER THE LOWER 48. AS SUCH, INLAND
MOISTURE RETURN AND THE POTENTIAL FOR THUNDERSTORMS APPEARS
UNLIKELY.
