PRECIPTTATIJN, SNOWFALL AND SNOW DEPTH SUMMARIES

PERCENTAGE FREQUENCY OF VARIOUS DAILY AMOUNTS OF PRECIPITATION (SNOWFALL AND SNOW DFPTH) SUMMARIES:

THESE SUMMARILS DERIVE FROM SUMMARY OF DAY DATA.

DATA ARE SUMMARIZED MONTHLY AND ANNUALLY WITH ALL YEARS COMBINED.

DISPLAYED ARE: PERCENT OF DAYS WITH MEASURABLE AMOUNTS, A PERCENT OF DAYS WITH NO AMOUNTS, TRACES, GIVEN AMOUNTS,MEANS. GREATEST AMOUNTS AND LEAST AMOUNTS IIHL STATISTICAL VALUES ARE NOT INCLUDED IN THE SNOW

DEPTH SUMMARY BECAUSE OF THEIR DOUBTFUL AND LIMITL VALUE).

ALSO PROVIDED AkE THE ObSE0VATTON COUNTS.

A VALUE OF ".0" IN THESE TABLES INDICATES LESS THAN .Cc% WHICH USUALLY INDICATES ONLY ONE OCCURRENCE.

EXTREME DAILY AMOUNTS OF PRECIPITATION (SNOWFALL AND SNOW DEPTHI SUMMARIES:

DATA DERIVED FROM SUMMARY OF DAY DATA

PRESENTED ARE THE EXTREME DAILY AMOUNTS Of PRECIPITATION, SNOWFALL AND SNOW DEPTH BY INDIVIDUAL mONTH AND YEAR.

ALSO PRESENTED ARE THE MEANS, STANDARD DEVIATIONS AND TOTAL OdSERVATION COUNTS.

AN ASTERISK "*" PRINTED IN THE TABLES INnICATES THAT THE EXTREME VALVE FOR THAT YEAR AND MONTH

DERIVES FROM AN INCOMPLETE MONTH (AT LEAST ONE DAY OF THE MONTH IS MISSINU).

WHEN A MONTH HAS VALID OBSERVATIONS REPORTED BUT NO OCCURRENCES. ZEROS APE DISPLAYED IN THE TABLES:

EXTREME DAILY PRECIPITATION: ".0' EQUALS NONE FOR THE MONTH (HUNDREDTHS)

EXTREME DAILY SNOWFALL: .. O" EQUALS NONE FOR THE MONTH (TENTHS)

EXTREME DJiLY SNOW DEPTH: *C0

EQUALS NONE FOR THE MONTH 4WHOLE INCHES)

TOTAL MONTHLY AMOUNTS OF PRECIPITATION ANO SNOWFALL SUMMARIES:

DATA DERIVED FROM SUMMARY CF DAY DATA.

DATA PRESENTED BY YEAR AND MONTH.

ALSO PRESENTED ARE THE MEANS, STANDARD DEVIATIONS AND TOTAL OBSERVATION COUNTS.

AN ASTERISM "*" IN THE TABLES INDICATES THAT ONE OR MORE DAYS WERE MISSING FOR THE MONTH.

NO OCCURRENCES FOR THE MONTH ARE INDICATED BY ZEROS.

IF THE AMOUNT IS A TRACE, THEN "TRACE" IS PRINTED IN THE TABLES.

EXTREME VALUES OF PEAK WINDS:

DATA DERIVED FROM SUMMARY OF DAY DATA.

VALUES PRESENTED BY INDIVIDUAL MONTH AND YEAR WITH ALL YEARS COMBINED.

SPEEDS PRESENTED IN KNOTS.

DIRECTIONS PRESENTED IN lb COMPASS PDINTt

FROM bEGINNING OF PERIOD OF RECORD THROUGH JUNE 1966.COMMENCING JULY 1968 DIRECTIONS PRESENTED IN TENS OF DEUREES.

AN ASTERISK "4" IN THE TABLES INDICATES THAT THE VALUE IS BASED ON AN INCOMPLETE MONTH OF THREE OR MORE
