Five notable events that affected Topeka in 2007
The Killing Freeze of Early April:
The month of March brought an abrupt end to winter and ranks as the third warmest March on record. The heat was so persistent in March that much of the local vegetation went into early bloom. This early bloom encouraged some people to get an early jump on landscaping, and delicate vegetation was not uncommon by the first week in April. Unfortunately, in early April, an arctic airmass pushed south through the Central Plains bringing a 4 day period (April 4th-8th) where the average temperature was just above freezing. Overnight lows dipped into the teens at several locations, killing much of the planted vegetation and destroying blossoms on almost all trees and shurbs. While early April freezes are not unprecedented, this 4 day period ranks coldest of any such period on record for the month of April. This cold snap, when combined with the very warm March, greatly stunted the growth of local vegetation during the Spring of 2007.
Major Flash Flooding of May 6th and 7th:
Persistent thunderstorm activity brought very heavy rainfall through much of North Central, Northeast and East Central Kansas. At Topeka Billard Airport 7.72 inches of rain was measured over the two day period with 5.10 inches falling on May 6th. The May 6th rainfall total ranks as the highest daily rainfall total ever measured during the month of May in Topeka. This daily rainfall total ranks as the third highest daily rainfall total on record in Topeka for any day of the year. This heavy rainfall caused widespread flash flooding throughout the area. In Topeka, numerous homes and businesses were inundated with flood waters. Hundreds of water rescues were performed for flash flooding along the Shunganunga Creek in town. Thankfully, no deaths were reported as a result of this widespread flash flooding event in Topeka.
Heat wave of late July and August:
The ’dog days’ of summer were in full swing in 2007 with persistent heat and humidity in place over much of the region. Several days from late July through late August saw heat indices climb near or above 105 degrees. While heat indices near 105 degrees are relatively common for a few days in the summer, the persistence of the heat and humidity is what made the period remarkable. Temperatures from July 27th through August 23rd never fell below 70 degrees, offering no relief from the persistent daytime heat. The average temperature this August ranked as the 8th warmest on record.
Ice Storm of December 10th and 11th:
A strong winter storm system brought periods of moderate to at times heavy rainfall over Topeka while surface temperatures remained just below freezing. During the period 2.69 inches of rain was measured with a half to three quarters of an inch accumulating as ice. Heavy ice accumulations combined with winds of 15 to 20 mph to cause extensive tree and powerline damage throughout the city. Widespread and long term power outages resulted from the damage and the extensive damage to trees throughout the city remains evident.
Heavy snowfall of December 22nd:
Another strong winter storm in a series of low pressure systems that moved through Northeast Kansas in a busy December brought 9 inches of snowfall to Billiard Airport in Topeka. The 9 inches marks the heaviest snowfall in Topeka since January of 1993. The snowfall also ranks as the seventh highest one day snowfall total on record in Topeka. The heavy snowfall of December 22nd was the highlight snowfall event of the second snowiest December on record in Topeka.
