Missouri generally has a variety of seasonal humid subtropical climate (Köppen climate classification Cfa), with cool winters and long, hot summers. In the southern part of the state, particularly in the Bootheel , the climate borders on a more mild-type humid subtropical climate (Köppen Cfa ), and in the northern third, the state transitions ...
The heat wave of 2006 derecho series were a set of derechos — severe winds with powerful thunderstorms — that occurred on July 17–21, 2006. The first storms hit a wide swath of north-central and northeastern North America that stretched from the Upper Midwest through much of Ontario and into the northeastern United States.
As the storm crossed the Mississippi River into Downtown Memphis, a barge recorded an unofficial wind reading of 108 mph (174 km/h). Coincidentally, the National Hurricane Center's rotation of tropical cyclone names had identified that season's "D" storm, "Danny ," only two days earlier, thus the region's next real hurricane, Hurricane Erika ...
The largest wind and rain damages were reported in Zagreb, where the wind speed, measured at Zagreb airport, reached 115 km/h, and the amount of precipitation was 20 to 35 mm in only 10 minutes. As a result of what was, possibly, the strongest storm on the record in Zagreb, the city was left with fallen trees, flooded areas, and widespread ...
Although springtime in Missouri is likely to be wetter, summer droughts are likely to be more severe. Higher evaporation and lower summer rainfall are likely to reduce river flows. The drought of 2012 narrowed navigation channels, forced lock closures, and caused dozens of barges to run aground on the Mississippi River along the Missouri shoreline.
These winds diminished slightly as the derecho approached the Mississippi River, though gusts of 80–100 mph (130–160 km/h) remained widespread. The more extreme corridor of wind gusts transitioned into a broader swath of 60–70 mph (97–113 km/h) winds as the storm moved across northern Illinois and northwestern Indiana between 2–5 p.m.
Berg wind, a seasonal katabatic wind blowing down the Great Escarpment from the high central plateau to the coast in South Africa.; Cape Doctor, often persistent and dry south-easterly wind that blows on the South African coast from spring to late summer (September to March in the southern hemisphere).
The drought and heat wave conditions led many Midwestern cities to experience record heat. In Kansas City, Missouri, the high temperature was below 90 °F (32 °C) only twice and soared above the century mark (100 °F or 38 °C) for 17 days straight; in Memphis, Tennessee, the temperature reached an all-time high of 108 °F (42 °C) on July 13, 1980, part of a 15-day stretch of temperatures ...
