HAZARDOUS HIGHS -- We usually associate low air pressure with stormy weather and high pressure with "fair weather", a somewhat subjective term used to describe pleasant weather conditions, with no precipitation and few clouds.

HISTORICAL WEATHER EVENTS - 12 April

From the files of the Aviation Weather Center, Kansas City, MO and Intellicast

...1927...An F5 tornado wiped out the town of Rock Springs, TX killing 74 persons and causing 1.2 million dollars damage. The tornado, more than one mile in width, destroyed 235 of 247 buildings, leaving no trace of lumber or contents in many cases. Many survivors were bruised by large hail which fell after the passage of the tornado. (David Ludlum) (The Weather Channel)
...1934...Winds atop Mount Washington, NH (elevation 6288 feet) averaged a world record 186 mph for five minutes, with a peak gust from the southeast of 231 mph, the highest wind speed ever clocked in the world. (David Ludlum)
...1945...Antlers, OK was leveled by an F5 tornado. Six hundred buildings were destroyed and 700 were damaged. Sixty nine people were killed and 353 were injured. This disaster would have commanded national and local attention if it were not overshadowed by the death of President Franklin D. Roosevelt. Even nearby local newspapers had more information on the president than the tornado. (Intellicast)
