the warm front moved through late this afternoon or early this evening. it help fire up the remnants of the midwest MCS that wreaked havoc over MN, IL, and WI.

behind the warm front, our temps have increased this evening with the stronger s-sw winds. our dew points are now in the low 70s at 8:00 p.m. wow.

The warm front moved through our area late this afternoon or early this evening. Behind the front, our wind speeds have increased to 15 to 30 mph from the south-southwest, causing our temps to rise a few degrees this evening.

At 8:00 p.m., Toledo area temps were in the mid 80s with dew point temps in the low 70s. Conditions are certainly ripe at the low levels.

A line of thundershowers formed recently in central lower Michigan, and this line is dropping southeastward. We could get some rain from this, but I don't think this is the main weather system for late tonight.

I think that the severe thunderstorms currently over Wisconsin will also drop southeastward, and this could be our main weather issue after Midnight.

Strong storms currently exist in Illinois and Iowa, moving eastward. I'm unsure what their role will be in our weather.

Tornado warned counties currently exist in Wisconsin and Illinois.

areas affected...srn lower mi...nwrn oh...nrn indiana...nern il

concerning...severe potential...tornado watch likely

valid 230031z - 230130z

probability of watch issuance...80 percent

summary...tornado watch may be required by 01z from lower mi swwd
into nern il.

discussion...large scale ascent appears to be increasing across
lower mi per expanding elevated convection that is evolving atop
boundary layer stratus. while 00z sounding at dtx is notably
capped...800mb temperature is 7c cooler at grb in closer proximity
to short-wave trough. cooling profiles across this region should
contribute to weaker inhibition over the next few hours and elevated
convection is expected to strengthen and near-sfc based tstms will
likely evolve with time...especially over srn lower mi into nrn
indiana. shear profiles strongly support deep rotating updrafts and
given the instability observed supercells should evolve.
additionally...discrete supercell over nrn il is expected to track
sewd along decayed outflow boundary to the south side of the chicago
metro area over the next few hours. this activity could spread into
nwrn indiana later this evening.
