...Dry start to July with a wet finish...

Following two dry months of May and June, July 2018 started with its
own dry spell, one that brought considerable brownness to local
vegetation. The parched ground coupled with surges of very warm air
aloft brought surface temperatures well into the 80s and lower 90s
the first half of the month. Following three weeks of dry and hot
weather, a slight pattern change allowed for a wetter finish to the
month...with drought relief thunderstorms and not as hot
temperatures.

The temperature averaged 74.4 this month which is 3.3 degrees above
normal and 9th warmest on record. There were 24 days reaching 80F
this month, 6 more than the airport observing site normal and 4 days
reaching into the 90s, which is double the normal since observations
moved to the airport in July of 1943. The first half of the month
averaged about 3 degrees warmer than the second half. There was one
new temperature record set, with 93F on July 4th breaking the now
former record of 92 set back in 1988.

Precipitation for the month totaled 2.15 inches which is just over
an inch below normal. The bulk of this precipitation fell the last
10 days of the month, with just a third of an inch recorded for the
month until very late on the 21st. Coupled with the dry end to
Spring, and dry start to summer the lack of precipitation brought
considerable brownness to area vegetation. A moderate drought formed
by mid month across much of the northern Niagara Frontier.

A heat wave continued from June into the first 5 days of July, with
temperatures in the upper 80s to lower 90s. The holiday of July 4th
was dry for many but with oppressive heat. A weak cold front passed
across Western New York on the 5th, ending the sweltering heat, and
also sparking a few heavy thunderstorms across the region. Storms
this day, as with much of the first half of the month fell during
the afternoon and evening hours and were spotty, tending to favor
the southern half of New York State. This allowed for dry conditions
to worsen across much of Western New York. An area of low pressure
lifted northward from the mid Atlantic region on the 21st, bringing
rain to the region late in the day. The last 10 days featured a
pattern change, with an upper level low favoring near the Ohio
Valley and a broad area of high pressure over the western Atlantic,
and between these features tropical moisture flowed northward. The
moisture increased the dewpoints, though an increase in cloudiness
maintained temperatures in the mid 70s to mid 80s, cooler than the
first half of the month. Showers and thunderstorms brought much
needed rainfall to Western New York on more days than naught the
last 10 days of the month...though heavy soaking rains eluded most
areas.

Lake Erie warmed from 69F at the start of the month to 75F degrees
mid month. Winds were below normal this month, and strong wind gusts
absent with the strongest gust just 31 mph on the 9th, 26th, 27th
and 28th.

In all a dry month, with a pronounced heat wave to start.
