...RIVERS `ROSE TO THE OCCASION` AS SEVERAL HEAVY RAIN-PRODUCING
THUNDERSTORMS HIT THE REGION...

As usual May was an active month as numerous thunderstorms, of which
several were severe, struck Kansas. A `grand slam` of severe weather
resulted: Large hail, damaging winds, a few tornadoes, and this time
torrential rains that caused widespread flooding. The flooding was
aggravated when many rivers `rose to the occasion`. In some cases,
the river flooding lasted nearly a week.

The severe thunderstorms got off to a fairly late start as the first
batch didn`t arrive until the 10th, but the flooding was already in
progress.

The first round of flooding was actually carried over from April,
when 2 to 4 inch rainfalls drenched most of Southeast Kansas on the
29th. The Flood and Flash Flood Warnings that were issued for most
of Southeast Kansas on the 29th, most notably Labette and Montgomery
Counties, were extended to May 2nd. Major rivers, such as the Neosho
and Verdigris, were already in flood, so in the Flooding Department,
May had a running start.

On May 2nd and 3rd, more heavy rains hit Southeast Kansas with many
areas soaked by 2 to 3 inches and this time, Southeast Kansas shared
some of the `wealth` with South-Central Kansas, where the Arkansas
and the Chikaskia Rivers reached their respective flood stages.

Not even a week passed when a 2-day drenching sent several rivers
over their banks. In nearly all cases, the river flooding was in the
"minor" category, but there were exceptions. On the 9th and 10th,
widespread 2 to 3 inches soaked South-Central and most of Southeast
Kansas. Southeast Kansas caught the brunt of the rainfall again as a
few locations were inundated by 4 to 5 inches.

This time, the flooding was more serious. On the 10th, a flash flood
that struck the southeast side of Sedan was so strong that a metal
culvert was overwhelmed, causing the road to wash out. On the 11th,
widespread flooding occurred in Kingman County, including downtown
Kingman. Roads and highways were barricaded in several areas, most
notably Kingman, Sumner and Butler Counties.

Severe Thunderstorm Highlights:

May 11th:

A few of the heavy rain-producing thunderstorms that struck South-
Central Kansas on the 11th also unleashed 60 to 70 mph winds that
uprooted trees and downed power lines in Kingman County.

May 16th:

Severe thunderstorms struck Central Kansas each afternoon and
evening. A few thunderstorms were tornadic.

On the 16th, 4 tornadoes struck Barton County. One was significant.
An EF-3 that started in Eastern Pawnee County 3 miles east of Larned
had raced 5 miles when it crossed into Southwest Barton County. In
Barton County, the twister tacked on another 22 miles and reached
300 yards wide. The EF-3 damage occurred just west and northwest of
Great Bend where a farmhouse built in 1890 was demolished. One
person was injured.

May 18th:

The severe thunderstorms that occurred late that afternoon and
evening struck a much larger area. Straight-line winds caused a wide
swath of damage from Barton to McPherson and Saline Counties. In
addition to tree and power line damage, a semi truck was blown over
on Highway 56. The severe thunderstorms ventured into Greenwood
County later that evening where downed power lines severed power in
Hamilton. Hail was as large as golf balls and 4 small, weak
tornadoes occurred in Barton and Saline Counties.

May 19th:

A spate of tornadoes touched down in Kingman, Reno, and Chase
Counties from mid-afternoon to mid-evening. There were 7 tornadoes,
a few of which produced damage across portions of Kingman and Chase
counties. The Chase county twister achieved an EF-1 rating northwest
of Elmdale.

May 25th-May 27th:

The bouts of severe thunderstorms that occurred during these periods
were prolific hail-producers. The largest hail was around 2 inches
in diameter and hammered parts of Russell County where 60 to 70 mph
winds also lashed the county. On the 27th, South-Central and
Southeast Kansas were hit by hail as large as golf balls along with
several reports of ping pong ball-sized stones.

May 31st:

The month ended when scattered thunderstorms developed along and
south of a stationary front that was draped in an east/west manner
across Central Kansas. Many produced hail. One thunderstorm was
severe when reports of golf ball and half dollar-sized hail were
received from Harvey County that afternoon.

Temperatures:

Believe it or not, there were a few things that were normal in May.
Those were average temperatures. Wichita`s monthly average of 65.9
degrees was only 0.1 degree "below" normal. Salina`s average of 65.8
degrees was 0.5 degree above normal while Chanute`s average of 66.1
degrees was 0.2 degree "above" normal.

Rainfall:

Although there was tremendous rainfall from 2nd to the 3rd and from
10th to the 11th that caused so much flooding, no rainfall records
were set or tied, although Chanute did come close, but on only 1
occasion; and that wasn`t really all that close. The 3.37 inches
measured on the 11th was the 2nd greatest for the date, exceeded
only by the 4.90 inches measured on May 11th, 1929.

Monthly rainfall totaled 4.44 inches at Wichita, (0.13 inches below
normal), 3.87 inches at Salina (0.88 inches below normal), and 5.89
inches at Chanute (0.09 inches above normal).

Y`all have a great summer, but be very careful when the atmosphere
turns up the furnace. Heat ranks number 1 on the deadliest weather
hazards list. When outdoors, have plenty of cool water available.
Never, ever, leave pets or children unattended in a vehicle for any
duration!

Please heed all advice provided by the National Weather Service when
Heat Advisories and Excessive Heat Warnings are issued.
