And just as I ask why:
Warning Description: Excessive Heat Warning
Warning Date: 3:23 PM CDT on August 6, 2007
WarningSum:...Excessive Heat Warning In Effect From 12 Pm Tuesday To 7 Pm
Cdt Friday...
Warning Message:The National Weather Service in Pleasant Hill has issued an
excessive heat warning...which is in effect from 12 PM Tuesday to
7 PM CDT Friday.
A ridge of high pressure...currently centered across the lower Mississippi
River valley...has trapped hot and humid air across the Central
Plains. This airmass is not expected to go anywhere over the next
four days allowing the heat to build up across eastern Kansas and
much of northern Missouri. By Tuesday afternoon...heat index
readings are expected to range at or above 105 degrees for several
hours across areas along and south of Highway 36 from St Joseph...to
Chillicothe...and Macon. Additionally...overnight temperatures across
the warned area are not expected to cool much overnight...with lows
bottoming out only as low as the mid 70s in rural areas...and staying
near 80 in more urban areas.
An excessive heat warning is issued when the combination of hot
temperatures and high humidity is expected to result in heat
indicies exceeding 105 degrees for at least 3 hours...for three or
more consecutive days. Be sure to drink plenty of fluids...stay
in an air-conditioned room...stay out of the sun...and check up
on relatives and neighbors.
But it's for tomorrow from noon to 7 pm Friday
