A dangerous tornado outbreak is expected on
Saturday over the Plains, says NOAA's Warm, moist air flowing northwards from a Gulf of
Mexico that has record-warm waters will collide with cold air funneling down
from Canada, creating a highly unstable air mass capable of creating strong
thunderstorm updrafts. An impressive upper-level low, accompanied by a jet
stream with 105 - 125 mph winds at middle levels of the atmosphere, will create
plenty of wind shear, giving the air the spin it needs to form tornadoes. SPC
has has issued their highest level of alert, a "High Risk," for portions of
Oklahoma and Kansas for Saturday. Included in the "High Risk" area are the
cities of Wichita and Oklahoma City. This is the second time SPC has issued a
"High Risk" forecast this year; the first "High Risk" forecast came for the
March 2 tornado outbreak, which killed 41 people and did $1.5 - $2 billion in
damage. It is very unusual for SPC to issue a "High Risk" forecast more than a
day in advance of a suspected tornado outbreak; according to Wikipedia,
today's "High Risk" forecast is only the second time SPC has ever done this. The
other instance was for the April
6 - 8, 2006 tornado outbreak
focused over Tennessee, which generated 73
tornadoes that killed 13 and did $1.5 billion in damage. People living in the
threatened area need to pay close attention on Saturday to this dangerous severe
weather situation.
