made some minor tweaks to mainly pops this morning into this
afternoon. initial area of returns is encountering a fairly dry
airmass, resulting in little more than some sprinkles making it
to the ground. with time as saturation continues some light to
maybe locally moderate rain will settle into mainly far nw areas
near/after 15z and then most likely linger into the afternoon as
high pressure tries to hold on. qpf will likely remain below
0.10". questions exist as to how far se this initial surge of
isentropic lift will make it. will continue to sort out those
details in the coming hours.

not a whole lot of changes to the going forecast. rain showers
continue over northern il into central mi this morning with the
band of showers on the northwest periphery of ridging further
south and east which will mainly keep the introduction of rain
showers for areas closer to lake michigan into this afternoon
as the lower levels further moisten. wpc has a marginal risk for
excessive rainfall for later today and as the ridging pushes
further south and east rain showers will make their way further
south and east through friday morning with a slight risk for
excessive rainfall for tomorrow. a few embedded thunderstorms
will be possible with the southern and eastward push but at this
time severe weather is not anticipated.
a more zonal aloft pattern emerges across the region this
weekend and will bring a return to dry conditions and cooler
temperatures especially into the beginning of next week when
highs will only get to around 60 degrees both monday and
tuesday.

light rain showers currently observed on latest radar imagery
starting to push into northwest in with some of the showers
making it to the surface. these showers are on the
northwestern periphery of ridging in place further south and
east. showers look to remain light as the showers push further
southward over mainly areas near lake michigan and into ksbn, so
at this time think conditions will mainly remain vfr however
some slight reductions in vsbys due to rain showers may allow
for mvfr vsbys but at this time confidence remains low. at this
time kfwa looks to remain dry with the ridging in place over
south and eastern portions of the cwa.
