...KCXX RADAR IN COLCHESTER VERMONT WILL UNDERGO DUAL POLARIZATION
UPGRADE ON JULY 18TH AND BE OUT OF SERVICE UNTIL AUGUST 1ST...
THE NATIONAL WEATHER SERVICE KCXX WSR-88D DOPPLER RADAR LOCATED AT
CAMP JOHNSON IN COLCHESTER VERMONT AND OPERATED BY THE NATIONAL
WEATHER SERVICE OFFICE IN BURLINGTON, VERMONT WILL BE OUT OF SERVICE
FOR AN UPGRADE TO DUAL POLARIZATION (DUAL POL) TECHNOLOGY BEGINNING
ON WEDNESDAY JULY 18TH THROUGH WEDNESDAY AUGUST 1ST. MOST
INSTALLATIONS HAVE TAKEN ABOUT A WEEK TO COMPLETE AND IF NO PROBLEMS
OCCUR AT KCXX RADAR, THEN SERVICE COULD RETURN SOONER THAN AUGUST 1ST.
 
THIS IS THE LARGEST HARDWARE UPGRADE TO THE WSR-88D RADAR SINCE ITS

WAYS...CATEGORIZING THE TYPE OF PRECIPITATION THAT IS FALLING (RAIN,
SNOW, HAIL, ETC), IMPROVE ESTIMATES OF TOTAL PRECIPITATION, BETTER
ESTIMATION OF THE SIZE DISTRIBUTION OF HYDROMETEORS, UPGRADE THE
ABILITY TO IDENTIFY AREAS OF HEAVY RAINFALL RATES FOR FLASH FLOOD
POTENTIAL, BETTER DETECTION AND MITIGATION OF NON-WEATHER ECHOES,
EASIER IDENTIFICATION OF THE MELTING LAYER FOR ENHANCED FORECASTING
OF SNOW LEVELS AND NEW SEVERE THUNDERSTORM SIGNATURES FOR HAIL.
DURING THE SCHEDULED KTYX RADAR DOWNTIME...THE FOLLOWING SURROUNDING
RADARS SHOULD BE UTILIZED FOR RADAR DATA:

KENX...ALBANY, NEW YORK
KGYX...GRAY, MAINE
KTYX...MONTAGUE, NEW YORK
