.AVIATION...

Scattered -SHRA/-TSRA were noted northwest of ktxk this morning,
courtesy of a nearby upper level disturbance. Computer models hint
at this precipitation activity being maintained north of ktxk
though would not be surprised of a stray -SHRA/-TSRA nears the 
said terminal. However, confidence is not high enough to insert a 
mention at this time but will of course amend as necessary. 
Concurrently, -SHRA have been struggling to develop west of klfk 
and once again will elect to not insert a precipitation mention. 
MVFR fog and CIGS have developed south of klfk and would not be 
surprised if either phenomena affects kggg, ktyr and kmlu later 
this morning. Have hinted at this potential with a SCT mention at 
kggg and ktyr, but recent trends suggests that a TEMPO group at 
kmlu and klfk is appropriate. Otherwise, light southerly or calm 
winds of this morning will veer to the south-southwest by late 
morning, with speeds increasing to around 10 kts by the afternoon 
/breeziest conditions to occur across the western terminals/. 
Shortly after sunset, wind speeds will drop to below 10 kts and 
hints of VFR-MVFR fog could plague klfk overnight. /29/

Historical Weather And Climate Facts For Today

///////////////////////////
AUGUST 15TH...HISTORIC WEATHER EVENTS
...1787...
Tornadoes were reported in Connecticut, Rhode Island, Massachusetts, and
New Hampshire. Wethersfield CT was hard hit by the tornado outbreak. (David
Ludlum)
...1946...
Saint Louis MO was deluged with a record 8.78 inches of rain in 24 hours.
(The Weather Channel)
...1967...
The "sundance fire" in northern Idaho was started by lightning. Winds of 50
mph carried firebrands as much as ten miles in advance to ignite new fires,
and as a result, the forest fire spread twenty miles across the Selkirk
Mountains in just twelve hours, burning 56,000 acres. The heat of the fire
produced whirlwinds of flame with winds up to 300 mph which flung giant
trees about like matchsticks. (David Ludlum)
...1987...
Thunderstorms developing ahead of a sharp cold front produced severe
weather in the Upper Midwest during the afternoon and evening hours, with
Minnesota and eastern South Dakota hardest hit. A thunderstorm in west
central Minnesota spawned a tornado at Eagle Lake which killed one person
and injured eight others. A thunder- storm in eastern South Dakota produced
softball size hail at Warner. (The National Weather Summary) (Storm Data)
...1988...
Thirty five cities in twenty states in the north central and northeastern
U.S. reported record high temperatures for the date, including Lamoni IA
and Baltimore MD, where the mercury hit 105 degrees. Temperatures 100
degrees or above were reported in twenty-two states. Pierre SD was the hot
spot in the nation with a high of 114 degrees. Bluefield WV reported eight
straight days of record heat. (The National Weather Summary)
...1989...
Evening thunderstorms in eastern New Mexico produced wind gusts to 66 mph
