*** D I S C U S S I O N ******************************************

The new year got started on a mild note with above normal
temperatures for the first 9 days of 2016. It would cool off for the
middle part of January with subzero lows occurring on 8 out of 10
days between the 10th and 19th. Mild conditions would round out the
month, with highs almost breaking 40 on the 30th (39 degrees).
Overall, January would finish around a degree below normal. Snow was
often but in very small amounts. A trace or more was recorded on 17
of the 31 days, but measurable on only 9 days. Of those, there was
only 2 days with over an inch of snow (high of 1.6" on the 8th).

After a couple mild days, temperatures took a downward turn for the
front half of February. Temperatures were at or below normal for 10
of the first 14 days, with a string of below zero lows for the 10th
through 13th. The second half would see a return of the milder
conditions as highs cracked 40 degrees 4 times, reaching 52 on the
27th. Lows were at or above 30 degrees 17% of the time, well above
the average of 6%. February snowfall was front loaded, with all the
measurable snow coming through the 15th.  There were only 3 days
with flurries after that. The bulk of the snow came on the 2nd and
3rd with 8.9 inches.

It would be a mild March for Rochester in 2016 with its 38.5 degree
average making it the 8th warmest on record. The bulk of the warmth
came during the front half. The stretch from the 7th through 15th
recorded highs of 50 degrees or warmer on 7 of those days, with lows
mostly in the 40s (closer to the normal highs rather than lows). The
first 60 degree day of the year came on the 7th (62), which was the
9th quickest 60 degree or warmer temperature in a year for Rochester
(average is around March 28th). Along with being very mild, March
was a wet month. Measurable precipitation fell on 14 days with over
1/2 inch of precipitation on 4 of those. The 3.98 inch total made it
the 3rd wettest March on record. About half of that came as snowfall
with 14.9" falling through the month (well above the 8.7 inch
normal). That said, the mild air made sure that when it snowed it
did not stick around long. March harbored one of the windiest days
of 2016. The 16th averaged 25.5 mph for the day and recorded a peak
wind gust of 52 mph.

April experienced a lot of fluctuation when it came to temperatures,
typical for this spring month. There were 11 days when highs could
not climb to 50 degrees, while 9 days reached 70 or greater - with a
max of 80 on the 16th. The biggest swing in temperatures came at the
start of the month with a high of 35 on the 2nd, jumping to 72 on
the 3rd, then falling back to earth for a chilly 40 on the 4th. The
3rd also has an impressive spread in the high and low for the day,
with a morning low of 25 degrees, rocketing up 47 degrees by the
afternoon.  April was a dry month, finishing 1 1/2 inches below its
normal. There were 14 days with measurable precipitation, but 10 of
those recorded less than 1/10 of an inch. The last measurable snow
of the winter season fell on the 8th with 0.5 inches.

Temperatures were just about on par for May, finishing just under a
degree above normal. Temperatures did experience a lot of swings
over the first half of the month, illustrated by a high of 90 on the
6th and a chilly 49 on the 13th and 14th.  The 90 degree day was the
first of the year and about a month earlier than normal. The latter
half of the month settled into highs mostly in the 70s with lows
near 60. Precipitation was almost an inch above the May normal, with
the bulk of the total coming over the last 9 days. Rain fell from
the 23rd through month`s end, accounting for 2/3rds of May`s total.
There was also a dry period mid month where only 0.02" inches feel -
the 14th through 22nd.

The average temperature of 48.1 degrees for the March, April and May
made it the 7th warmest spring on record for Rochester.

June kicked off the summer on a mild and wet note. There were 13
days with highs 80 degrees or warmer. The warmest day of 2016 came
on the 10th with a high of 93. Measurable rain fell on 13 days, with
7 of those recording over 1/4 inch and 3 over 1/2 inch.

July was right on its normal for temperatures, starting out a bit
cool, but quickly warming to its seasonable normal after the first
week. Highs reached 90 on the 21st and 22nd, the last time it would
reach 90 for the rest of the year. July was a wet month. There was
measurable rain on 15 days (4th most for a July), with 1/2 inch or
more on 5 days. There was an 8 day stretch of rainy conditions (10th
- 17th) with never more than 4 days between days with rainfall. The
strongest wind of 2016 came courtesy of a severe thunderstorm on the
5th, gusting to 57 mph.

August finished the summer months off on a warm and wet note,
finishing above normal for temperatures and rainfall. Temperatures
reached 80 degrees or warmer on 15 of the days, failing to reach 70
only once (69 on the 20th). There were 9 days with measurable rain
in August, right around what typically occurs. However, over 1/2
inch of rain fell on 5 of those days with an inch or more on 2 of

It was a wet summer in Rochester. The 16.58 inches was made it the
14th wettest on record.

The wet summer would give way to an even soggier September. The 9.10
inch total made it the 3rd wettest September on record for
Rochester, and 13th wettest for any month. There were 5 days with
over 1/2 inch of rainfall, 3 of those exceeded an inch. The most for
the month and year fell on the 21st with 3.60". Not only did this
set a record for the day, but it was the 19th wettest day on record.
In addition, it was just the 28th time that rainfall of 3 inches or
greater has fallen in a day at Rochester. Despite all the wet
weather, the warmth continued. The 67.7 degree average made it the
7th warmest September on record, tied with previous years.

The stretch from June through September was the 13th 4 month period
for Rochester with 24.96 inches. For comparison, the normal rainfall
for the entire year is 33.02 inches. So, 76% of the yearly normal
fell during these 4 months.

No end in sight to the mild conditions as the calendar rolled over
to October. The 52.0 average was over 3 1/2 degrees above normal and
18th warmest October on record. Temperatures reached freezing on the
8th, over a week later from the average for the first freeze of the
season. In addition, temperatures would reach or fall below 32 only
2 more times in October, well below the 10 day average for freezing
temperatures. Precipitation was 1/2 inch above normal, but the bulk
of the month`s rain came on 2 days: the 25th and 26th. These 2 days
accounted for nearly 70% (1.88") of the 2.74 inch October total.

November continued the warm fall conditions with only 3 days during
the month with below normal temperatures. The 42.8 average made it
the 2nd warmest on record while the 10 days with 60 degree or warmer
highs was the 3rd most for a November. The last 70 degree day of the
year came on the 5th (71), a couple weeks past the average for that
to occur. Sunshine was abundant for what is usually the cloudiest
month of the year, and with a lack of clouds also came a lack of
precipitation. There was no precipitation through the 17th, with 7
days of measurable precipitation after that. The first flurries of
the season came on the 18th with the first measurable snow on the
23rd (0.7").

The fall months of September, October and November finished as the
3rd warmest fall on record for Rochester at 53.1 degrees. There were
4th most 60 degree or warmer days this fall (58) and the least
amount of freezing days (only 16). The fall was also the 4th wettest
on record with 13.21 inches, mostly thanks to the very wet September.

were above normal for the start and end of the month, but a cold
stretch at mid month brought the monthly average down considerable.

13th through 18th. The coldest day came on the 18th with a high of
only -2 and a low of -25 (the coldest temperature of 2016 in
