...NO TSTM AREAS FORECAST...

...SYNOPSIS AND DISCUSSION...

MULTI-STREAM TROUGHING OVER THE WRN U.S. THIS MORNING WILL
CONSOLIDATE INTO A BROAD LONG-WAVE TROUGH WHICH IS FORECAST TO
ENCOMPASS THE WRN TWO-THIRDS OF THE NATION BY 04/12Z. WITHIN THIS
LARGER-SCALE REGIME...A STRONG SHORT-WAVE TROUGH OVER THE NWRN CONUS
WILL PROGRESS GENERALLY EWD AROUND AN UPPER LOW FORMING OVER
SASKATCHEWAN AND MANITOBA. THIS SYSTEM WILL BE ACCOMPANIED BY A
SUB-TROPICAL BRANCH IMPULSE SHIFTING FROM THE FOUR CORNERS REGION
THROUGH THE SRN PLAINS.

UPSTREAM FROM THESE DEVELOPMENTS...MID AND UPPER-LEVEL JET STREAKS
DEVELOPING EQUATORWARD FROM THE FAR NERN PACIFIC WILL CONTRIBUTE TO
HEIGHT FALLS AND TROUGH AMPLIFICATION FROM THE NRN INTER-MOUNTAIN
REGION THROUGH THE GREAT BASIN TO CA COAST. ELSEWHERE...AN INTENSE
TROUGH ALONG THE ATLANTIC SEABOARD WILL WEAKEN WHILE PROGRESSING
NEWD.

IN THE LOW LEVELS...AN EXPANSIVE ANTICYCLONE WILL SLOWLY BUILD EWD
ACROSS THE ERN HALF OF THE NATION WITH CONTINUED OFFSHORE FLOW ALONG
THE GULF COAST. THUS WHILE ISOLATED LIGHTNING STRIKES ARE POSSIBLE
WITHIN THE EVOLVING WRN U.S. TROUGH...LIMITED MOISTURE AVAILABILITY
IS EXPECTED TO PRECLUDE ANY MEANINGFUL TSTM POTENTIAL.
