For the 06Z TAFs...
Forecast concerns include wind directions...ifr cigs
Sunday morning and continued scattered showers.
Winds are generally northerly to north-northwesterly overnight. Wind
directions are expected to shift back north/northeast this morning
and then turn more to the northeast by late morning and into
Sunday afternoon. Speeds in the 10-15kt range with higher gusts
are again expected Sunday. Speeds/gusts will diminish quickly
with sunset Sunday evening.
Cigs are generally mvfr except near/over the lake. Guidance is in
good agreement with cigs lowering to ifr across northeast IL and
northwest IN later this evening and continuing into Sunday
morning, and we are starting to see this at UGN and PWK. Cameras
though are mixed as to the extent of the ifr clouds (more
scattered in nature). There will likely be some variability to the
cigs but continued ifr given the model consensus, though backed
off a little longer on arrival and how long they will last, where
confidence is lower. Some timing tweaks can be expected. Cigs
will lift through mvfr late Sunday morning/early Sunday afternoon
then to vfr later Sunday afternoon.
Scattered showers will be possible through early Sunday afternoon
across the entire area. The best times appear to be overnight
into Sunday morning, with vis quickly dropping to around 3SM in
the slightly stronger showers. Changes to precip timing are also
possible as trends emerge.
