northeast flow associated with a surface high pressure area that
was centered over lake superior was causing a northeast flow over
northern indiana and surrounding areas. dew points were only in
the 30s to around 40 early today. this chilly pattern will bring
one more cold night with lows dipping into the 40s over most
locations.
after tonight, energy in the form of short wave trofs will eject
east and bring showers and scattered thunderstorms north of the
ohio river. the next one of these systems will reach the forecast
area by late friday. moisture will spread over the midwest ahead
of this system. precipitable water values will rise anomalously
high and reach between 1.75" and 2.00" friday per gfs. overall
wind speeds and subsequent wind shear should stay weak. expect
storms will stay below severe levels but will be accompanied by
locally heavy rains.
chances for rain and storms will continue next week as
temperatures warm and as moisture increases over the area. a
large capping inversion will develop over the area during this
time. flow will remain weak, but moisture will remain high.
storm coverage should remain very limited until about wednesday
when some energy is able to eject out of the upper level trof
and make it into the midwest.
