...BEACH HAZARDS STATEMENT REMAINS IN EFFECT UNTIL 1 PM CDT THIS
AFTERNOON...

* LOCATION...Porter County Indiana Lake Michigan Beaches.

* HIGH WAVE ACTION AND DANGEROUS SWIMMING CONDITIONS EXPECTED.

* FORECAST WAVE HEIGHTS...3 to 5 feet.

* STRONG RIP CURRENTS AND STRUCTURAL CURRENTS EXPECTED.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Life threatening waves and currents are expected at the beaches.
People visiting the beaches should stay out of the water.

Rip currents are powerful channels of water flowing quickly away
from shore, which occur most often at low spots or breaks in
sandbars. Rip currents can sweep you into deeper water.

Structural currents form along piers where longshore currents and
wave action flow into the structure. Structural currents can
sweep you into deeper water along the pier structure.

Exposed beaches are more likely to experience the most
significant wave and current impacts. Impacts at beaches with
protective breakwalls or jetties will be subject to the
orientation of structures as well as wind and wave direction.

Area Forecast Discussion
National Weather Service Chicago/Romeoville, IL
302 AM CDT Fri Jul 27 2018

.SHORT TERM...
302 AM CDT

Through tonight...

Generally tranquil weather expected in the short term. Should see
SCT v BKN Cu deck blossom later this morning thanks to the
seasonably cold air aloft in association with the upper trough
over the region. Forecast soundings do indicate some weak low
level CAPE, but with equilibrium levels forecast to be at or below
10kft, opted to keep chance of measurable precip below thresholds
for mentionable precip. Wouldn't be surprising if a light shower
or a couple sprinkles develop along the lake breeze this
afternoon, but coverage and accumulation of precip will be sparse.

Temperatures will be seasonably cool today and tonight with highs
in the 70s today with temps a few degrees colder behind a lake
breeze this afternoon. Lake breeze expected to barely penetrate
inland over IL, but make it farther inland over NW IN thanks to
the northwesterly gradient flow.

.LONG TERM...
302 AM CDT

Saturday through Thursday...

Upper trough currently over the region isn't expected to move much
through most of the long term period. shortwave trough over
Alberta is expected to drop south and then gradually turn east
tracking along the southern periphery of the upper trough in our
area. The operational runs of the GFS and ECMWF actually close off
a mid-upper level circulation with this wave as it moves into the
Midwest early next week.

Rain chances and to some extent forecast temps will hinge on what
happens with this upper low. The 00z GFS and ECMWF both suggest
that the heavier steadier rain with this system will be over our
southern CWA or farther south. However, guidance does tend to
struggle with these type of systems, so will need to keep an eye
on model trends to make sure no northward shifts in the consensus
take place.

The closed low will eventually move east of the area with building
heights forecast in the wake of that system late next week.
Assuming that pans out as currently progged that would result in a
return to warmer and more humid weather by the end of next week.

.AVIATION...
For the 06Z TAFs...

1225 am...Only forecast concern this period is the potential for
a short period of high mvfr cigs this morning. Forecast moisture
fields suggest the potential for at least few/sct 2-3kft clouds
around/shortly after sunrise that should quickly lift to a 4-5kft
cig by late morning but confidence is low. Northwest winds will
continue through the period...increasing back to 10-12kts later
this morning...then diminishing with sunset this evening. Winds
will likely turn more northerly along the Indiana shore with a
north/northeast wind possible at gyy. cms

&&

.MARINE...

215 am...Low pressure near James Bay will lift northeast today as
a ridge of high pressure builds from the northern Plains into the
southern Great Lakes region this weekend. Northwest winds 10-20kt
today will slowly diminish tonight and gradually turn southerly by
Sunday but winds will remain light early next week as a ridge
settles over the Great Lakes. Low pressure will move northeast
across the Ohio Valley Tuesday which will turn winds northeasterly
over the southern portion of Lake Michigan. cms

.LOT WATCHES/WARNINGS/ADVISORIES...
IL...None.
IN...Beach Hazards Statement...INZ002 until 1 PM Friday.

LM...None.
