Area Forecast Discussion
National Weather Service Chicago/Romeoville, IL
625 PM CDT Fri Jul 28 2017

224 PM CDT

Through Saturday...

Quiet/dry conditions, with clear to partly cloudy skies and below
normal temps expected as high pressure continues to slowly build
south across the region. Tighter gradient on the fringe of this
high will allow a steady north northeast wind to persist, and
support continued dangerous beach conditions through the period.



224 PM CDT

Saturday night through Friday...

High pressure will continue to slowly build across the region
Saturday night. As this occurs, onshore winds may stay slightly
elevated through Saturday evening with dangerous beach conditions
possibly lasting slightly longer into the the evening. At this
time, no significant weather expected late this weekend into early
next week. Shower and thunderstorm chances increase towards the
middle of next week.



For the 00Z TAFs...

Northeast winds diminish this evening under clear skies. Saturday
looks like a repeat of today with northeast winds 10-15 kt and VFR
cumulus clouds. Quiet weather will continue into early next week.



329 PM CDT

High pressure to the north will continue to build south across
the region throughout the weekend, with northerly winds persisting
through this period. In the near term, tighter gradient in place
across the south half is allowing for the strongest wind speeds to
be occurring over this area this afternoon. This will likely
continue for most of tonight, with some slight diminishing trend
possible. Also, in the near term, not out of the question for
occasional gusts to 30 kt to occur over the south half and
nearshore waters this evening. These elevated winds and resultant
higher waves are providing hazardous conditions for small craft
this afternoon, and will continue tonight into Saturday morning. A
diminishing trend is likely across the entire lake Saturday into
Saturday night, with waves diminishing during this time. Will
continue to monitor possibly extending the small craft advisory
slightly longer on Saturday, to account for possible higher waves
still in place.



IL...Beach Hazards Statement...ILZ006-ILZ014 until 7 PM Saturday.

IN...Beach Hazards Statement...INZ001-INZ002 until 7 PM Saturday.
