a mid level trough axis along the eastern flank of an omega block
will drop through the lower and eastern great lakes late this
afternoon and evening. this will force any lingering sprinkles or
light showers associated with an elevated corridor of moisture
convergence south of the area by this evening. tuesday through
thursday will then feature a return to plentiful sunshine and
warming temperatures as ridging folds southeast into the great
lakes and ohio valley.
blocked pattern breaks down with a transition to flatter quasi-zonal
flow friday into this weekend. a higher theta-e air mass will
overspread during this time in return flow with highs well into the
80s and sfc dewpoints into the 60s. this will bring periodic chances
for showers and possibly a few thunderstorms friday afternoon
through sunday as a baroclinic zone likely settles over the region
and a slow moving, convectively augmented, vort makes a run at the
region during this time. as expected, daily confidence in pops is
low at this range with models are all over the place regarding
details.

increased theta-e moved into the area today ahead of a trough
rotating through in connection with an upper low in the northeastern
conus. this led to sprinkles this morning with ceilings above 7 kft
today. however, rain output is suppressed for our area in the
next taf period as subsidence takes over. as such, vfr
conditions continue.
as surface high pressure creeps back into the area tonight and for
tuesday, an increased pressure gradient on its front side resides
over our area and allows for a weak low level jet nearby, which may
be able to produce 20 kt gusts at fwa.
