PRELIMINARY EXTENDED FORECAST DISCUSSION
NWS HYDROMETEOROLOGICAL PREDICTION CENTER CAMP SPRINGS MD
358 AM EST WED JAN 05 2011
VALID 12Z SUN JAN 09 2011 - 12Z WED JAN 12 2011
EXPECT MOST OF THE CONUS TO REMAIN UNDER BELOW NORMAL HGTS ALOFT
FOR MOST OF THE MEDIUM RANGE PERIOD... CORRESPONDING TO
RIDGING/ABOVE NORMAL HGTS AT HIGHER LATITUDE. GUIDANCE IS SHOWING
SOME SHIFTING IN EMPHASIS WITH THE HIGH LATITUDE RIDGING... WITH A
WEAKENING TREND OVER CANADA AND A STRENGTHENING TREND OVER/NEAR
ALASKA. THIS TRANSITION SHOULD EVENTUALLY LEAD TO SOMEWHAT MORE
PACIFIC FLOW REACHING THE WRN CONUS. LATEST AND RECENT
MODEL/ENSEMBLE GUIDANCE SHOWS GOOD AGREEMENT WITH THE LARGE SCALE
SCENARIO THRU THE PERIOD.
