PRELIMINARY EXTENDED FORECAST DISCUSSION
NWS HYDROMETEOROLOGICAL PREDICTION CENTER CAMP SPRINGS MD
909 AM EST MON FEB 14 2005
VALID 12Z FRI FEB 18 2005 - 12Z MON FEB 21 2005
PRELIMINARY MEDIUM RANGE DISCUSSION...
...UPDATE...
USED THE 00Z/14 OPERATIONAL GFS FOR FRONTS AND PRESSURES FOR DAYS
3-7. LOOKING AT THE COMPLETE GUIDANCE PACKAGE FROM BOTH 00Z/14
AND 06Z/14...BELIEVE THAT THE 00Z/14 OPERATIONAL GFS SHOWS A
REASONABLE EVOLUTION OF THE LONG WAVE PATTERN ACROSS NA...AND AN
EQUALLY REASONABLE DEPICTION OF THE SFC MASS FIELDS. ECMWF HAS
WAFFLED A BIT DURING THE LAST FEW DAYS WITH REGARD TO TRACK OF
STORM AFFECTING ERN STATES DAYS 6 AND 7...GOING FROM A SUPPRESSED
SNOWY SOLUTION FOR THE MID ATL A COUPLE DAYS AGO...TO A RAINY IDEA
THE LAST TWO RUNS. WILL WAIT UNTIL IT SETTLES DOWN TO START
TAKING IT SERIOUSLY AGAIN.
Wow Fancy That,The Weather Changed----------JSB

NWS D.C. not willing to commit at all at this point. Models are too back and forth. Some parts north of D.C. got almost an inch of snow this morning. A light mix was the most agreesive model up until the event. They have been wrong so much this year for this area. Remeber, big thundersnow event last year was pretty late and pretty far south, Charlotte 21 inches of thundersnow- D.C. got a flurry. It is not over yet.
