VALID 291200Z - 031200Z
...DISCUSSION...
LARGE SCALE PATTERN WILL UNDERGO GRADUAL CHANGES INTO THE MEDIUM
RANGE WITH UPPER HEIGHTS EXPECTED TO RISE OVER THE MS VALLEY REGION
AND MORE SUBSTANTIAL TROUGHING OVER THE NRN INTERMOUNTAIN REGION.
NET RESULT WILL BE FOR BROADER BUT POTENTIALLY SUBSTANTIAL SWLY FLOW
ACROSS THE NRN/CNTRL ROCKIES INTO THE NRN PLAINS REGION. IF
SUFFICIENT INSTABILITY CAN DEVELOP EAST OF THE ROCKIES IT/S ENTIRELY
POSSIBLE THAT ONE OR MORE SEVERE EVENTS COULD EVOLVE ALONG A FRONTAL
ZONE AS IT PROGRESSES SLOWLY EWD. GIVEN THE UNCERTAINTY IN
INSTABILITY...AND POTENTIAL CAPPING ACROSS THE WARM SECTOR...WILL
MAINTAIN LOW PREDICTABILITY THIS PERIOD.
