The pressure gradient remains tight across the area this

Missouri from noon to 9PM Thursday where RH values will be

A cold front will move southeast through the area on Friday. A
dry air mass will be in place and moisture return will be

along and behind the front, there may be just enough instability
for a few embedded non severe storms on Sunday. A colder air
mass will advect into the area behind this air mass. Highs will
warm into the 50s on Sunday ahead of the front. Some of the
ensemble model members show light precipitation lingering into
the evening hours, ending from west to east on Sunday. As the
