...HEAT ADVISORY IN EFFECT FROM NOON TODAY TO 9 PM CDT THIS
EVENING...
.DISCUSSION...
Hot and muggy conditions will make potentially dangerous hot
conditions this afternoon into the evening. Heat indices this
afternoon could reach as high as 90, but if there is some
influence from Lake Superior, the heat index this afternoon may
only be in the mid 80s.
The firs round of storms this morning are expected to have a
minimal impact on the search. There is a dying storm approaching
the Twin Ports, but is projected to dissipate before it reaches
the site. Storms are expected to reform in the mid to late
afternoon, though exact timing is still uncertain. However, these
storms are expected to be strong to severe, with damaging winds,
large hail, and maybe a tornado or two possible. These will also
produce heavy rainfall, which could be up to 1 inch per hour at
times. Strong storms are expected to end for the Duluth area in
the late evening/early overnight, but general thunderstorms could
linger for a couple hours later.
