.DISCUSSION...
KEY MESSAGE 1) Temperatures getting back above normal through the
weekend.

A warm front will develop across northern portions of Indiana and
Ohio today with temperatures warming back above normal south of this
front. The warm front will lift further north tonight and southerly
low level flow will increase on Friday as the pressure gradient
tightens ahead of an approaching cold front. There could be gusts of
25 to 30 mph.

As the cold front moves through the area late Friday afternoon into
Friday evening, some showers and possibly thunderstorms may develop
down the boundary from northeast, where there is deeper lift from mid
level energy, to the southwest. Best chance of any measurable
precipitation will be in south central Ohio and northeast Kentucky.
But even there, much of the guidance is rather scant. HREF
probabilities of measurable rain are a bit higher than NBM while
the REFS probabilities are a bit lower. This seems to be related to
model differences in eroding a cap.

It appears that some stratus and possibly fog will develop Friday
night in the wake of the front which is forecast to dissipate early
Saturday. The post frontal airmass will knock down temperatures just
a few degrees from Friday. But warming will resume on Sunday with
temperatures rising into the mid to upper 70s, although it will be
breezy again, with gusts a bit higher than those on Friday.

KEY MESSAGE 2) Cold front on Sunday will bring a chance of
thunderstorms with temperatures falling back closer to normal early
next week.

Forcing looks a bit stronger with the next cold front late Sunday
into Sunday evening compared to Friday`s front. Once again, it
appears that precipitation will be developmental along the front as
it moves through the region, although with better forcing, the chance
of rain is greater with the higher PoPs east and south of I-71. Joint
probability of CAPE greater than 500 J/kg and bulk wind shear greater
than 30 kt is meager, less than 30 percent, with that relative
maximum focused near the Ohio River. Overall, any threat looks low at
this point, although some of the recent AI severe weather outlooks
have come in a bit more rambunctious.

Airmass in the wake of this front is colder than the Friday front. So
temperatures will drop back down closer to normal on Monday with
little change into Tuesday.
