..NO THUNDERSTORM AREAS FORECAST
..SUMMARY
THE RISK FOR THUNDERSTORMS APPEARS NEGLIGIBLE ACROSS THE U.S TUESDAY
THROUGH TUESDAY NIGHT.
..DISCUSSION
WHILE A BLOCKING HIGH TO THE NORTH OF THE ALEUTIANS MAY UNDERGO AT
LEAST SOME SHORT-LIVED SUPPRESSION, MODELS INDICATE THAT A
DOWNSTREAM HIGH MAY BECOME A BIT MORE PROMINENT ACROSS THE SOUTHERN
MID- TO SUBTROPICAL LATITUDES OF THE EASTERN PACIFIC DURING THIS
PERIOD. AS THIS OCCURS, A BELT OF STRONG ANTICYCLONIC FLOW IS
LIKELY TO BE MAINTAINED ACROSS MUCH OF THE EASTERN MID-LATITUDE
PACIFIC THROUGH THE NORTHERN U.S. INTERMOUNTAIN REGION AND ROCKIES.
ONE OF A NUMBER OF SHORT WAVE PERTURBATIONS PROGRESSING THROUGH THIS
JET IS FORECAST TO EMERGE AND CONTRIBUTE TO AMPLIFYING MID-LEVEL
TROUGHING AS IT DIGS ACROSS THE NORTHERN GREAT PLAINS THROUGH UPPER
MIDWEST, ACCOMPANIED BY A RAPIDLY MIGRATING SURFACE CYCLONE INTO THE
UPPER GREAT LAKES BY LATE TUESDAY NIGHT. IT APPEARS THAT THIS WILL
BE TRAILED BY A GRADUALLY CONSOLIDATING AND INCREASINGLY SIGNIFICANT
SURFACE COLD INTRUSION.
A NOTABLE PRECEDING SURFACE FRONT MAY REMAIN A FOCUS FOR
THUNDERSTORM DEVELOPMENT NEAR AND SOUTH-SOUTHEAST OF THE FLORIDA
STRAITS TUESDAY INTO TUESDAY NIGHT. THE TRAILING FLANK OF THIS
FRONT IS FORECAST TO WEAKEN ACROSS THE SOUTHWESTERN GULF BASIN, AND
SOME GULF BOUNDARY-LAYER MODIFICATION MAY COMMENCE TO THE NORTH.
HOWEVER, THIS IS LIKELY TO REMAIN RATHER MODEST, AND AN INITIAL
LOW-LEVEL OFFSHORE FLOW ACROSS THE GULF COAST, VEERING TO AN
INCREASING WESTERLY COMPONENT BY TUESDAY NIGHT, WILL TEND TO INHIBIT
INLAND MOISTENING.
