Flooding in Massachusetts, March 29 to 30, 2003

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBANY NY
430 PM EST SAT MAR 29 2003

.DISC...RAIN HAS BEEN HEAVY IN SOME LOCATIONS...BUT THE HEAVY RAIN
HAS BEEN BRIEF IN DURATION...SO NO SIGNIFICANT PCPN AMOUNTS REPORTED
THUS FAR.  WILL KEEP THE FLOOD WATCH UP SINCE INCREASED RUNOFF FROM
THE RAIN IS STILL OCCURING...AND HEAVIEST RAIN JUST MAKING IT INTO
ERN ZONES.  WILL LIKELY TAKE DOWN THE FLOOD WATCH LATER THIS EVENING
IF NO SIGNIFICANT HYDRO PROBLEMS MATERIALIZE.

A BRIEF RESPITE FROM STEADY PCPN LATE TONIGHT AND EARLY SUNDAY...THE
WAVE FORMING ALONG THE OFFSHORE COLD FRONT WILL BRING STEADY PCPN
BACK TO THE REGION...THIS TIME IN THE FORM OF SNOW.  ETA HAS BEEN
THE MOST AGRESSIVE WITH THIS EVENT...BUT EVEN THE ETA MODEL RUNS
(INCLUDING THE NEW 18Z RUN)...GENERALLY ONLY GIVE A LITTLE MORE THAN
HALF INCH TO A MAX OF THREE-QUARTES OF AN INCH LIQUID TO THE FCST
AREA DURING THE PERIOD WHEN ONLY SNOW WILL BE THE PCPN TYPE.  AT
THIS TIME OF THE YEAR...WITH A WETTER SNOW THAN USUAL LIKELY...THIS
WOULD SUPPORT A WINTER WEATHER ADVISORY TYPE OF EVENT FOR MOST OF
THE FCST AREA.

TOO EARLY TO ISSUE THE ADVISORIES NOW...BUT WILL LIKELY BE ISSUED
EARLY SUNDAY MORNING.

FOR NOW WILL ISSUE A WINTER STORM WATCH FOR THE EASTERN CATSKILLS
AND SOUTHERN VERMONT.  IN THESE AREAS...HIGH TERRAIN LOCATIONS AND
THE HEAVIEST QPF AREAS INTERSECT...SO THE POTENTIAL EXISTS TO EXCEED
SEVEN INCHES OF SNOW.

.HYDROLOGICAL DISCUSSION...AROUND A HALF AN INCH RAIN WILL FALL
THROUGH THIS EVENING IN MOST PLACES WITH MORE POSSIBLE SOUTHEAST
AREAS.  WARM TEMPS TODAY SHOULD PRODUCE LOTS OF SNOW MELT NORTHERN
HIGH TERRAIN AREAS.  THESE PRECIPITATION AMOUNTS WOULD BE MARGINAL
WERE IT NOT FOR THE ANTECEDENT CONDITIONS OF VERY SOGGY SOIL...
RIVERS RUNNING HIGH...AND THE HIGH DENSITY SNOW PACK IN THE
MOUNTAINS.  SO WITH THESE CONDITIONS...WILL CONTINUE THE FLOOD WATCH
FOR TONIGHT.

.ALY...FLOOD WATCH THIS TONIGHT FOR THE ENTIRE COUNTY WARNING AREA.
       WINTER STORM WATCH SUNDAY AFTERNOON AND SUNDAY NIGHT FOR THE
       EASTERN CATSKILLS AND SOUTHERN VERMONT.
