AUGUST RECORD HIGHS/LOWS/PRECIPITATION NORMALS/SUNRISE/SUNSET/NOTABLE WEATHER EVENTS

Based on official USWB/NWS data. Downtown Airport records since 1972 are noted with an asterisk. POMP is the Probability Of Measurable Precipitation for the day....TPoP is the probability of audible thunder for the day.....POMS is the Probability Of Measurable Snowfall for the day, all based on the 1888 to 1996 period. The normals are for KCI. The sunrise/sunset times were computed by the U.S. Naval Observatory program and vary slightly from year to year. Originally compiled by Allen Pearson.

                  NOTABLE WEATHER EVENTS IN AUGUST

Aug 1 1980  The morning low of 86 was the warmest low for the date,
while the afternoon high of 106 was the warmest high for the date. Not a 
very good start for August of 1980 after a very hot July.
Aug 4 1934  An intense heat wave began in 1934, with eight consecutive
days of record heat. By this time in 1934 the midwestern drought was in
full swing.
Aug 5 1993  The high temperature of 67 degrees is eight degrees cooler
than the next coolest maximum temperature (1912). 
Aug 6 1996 Two microbursts hit in the greater Kansas City area in the
early afternoon. The first ripped part of the roof off the Plaza Library
and swept a car (with three occupants) down an embankment and nearly into
Brush Creek. The second microburst struck at about the same time and caused
damage at Richard-Gebaur Memorial airport. Wind estimates were in the 70-80
mph range.
Aug 9 1934  The 110 degree reading was the sixth of eight consectutive
days of record heat.
Aug 10 1934 The 111 degree reading went down in the record books as
the warmest reading for any day since observations began in 1888, but the
record didn't stay in the book for very long.
Aug 12 1993 Pre-dawn thunderstorms hit Excelsior Springs, with rainfall
amounts up to 8 inches, turning a dry riverbed into a raging torrent. The
Fishing river and its Dry Fork branch sent a wall of water through the
Central business district.
Aug 12 1982 Showers and thunderstorms drenched the Kansas City area,
with as much as 14.55 inches in the southeastern suburbs over a two day
period.      
Aug 13 1936 This was the first of three days with highs of 110 degrees
or more.
Aug 14 1936 Kansas City experienced its hottest day of record for the
period 1888-1995, with 113 degrees. The average temperature for the day,
determined by (113+86/2) rounded off to 100 degrees, the only day in KC's
recent history with an average temperature in the triple digits.
Aug 16 1950 The high of only 89 degrees was the warmest for the month!
Aug 17 1956 A severe thunderstorm just before sunrise produced a wind
gust of 115 mph at the old Fairfax airport in Kansas City KS.
Aug 24 1934 The year had been a brutal one, so the high/low of 65/51
must have been a welcome relief to everyone.
Aug 27 1936 The last of 16 consecutive days with high temperatures of
at least 100 degrees.
Aug 29 1984 The temperature at the Downtown airport soared to 110 degrees
the first 110 reading in 30 years.
Aug 31 1988 The precipitation total for the calendar year stood at just
12.72 inches before heavy rains in September brought relief from the severe
drought conditions.
