Synopsis
Issued at 306 pm edt Fri aug 23 2019
expect dry conditions through the weekend. Highs will be in the 70s
and low 80s. Lows will range from the upper 40s to the mid 50s.

Hazardous swimming conditions are expected on southern lake michigan
through this evening. High wave action and dangerous currents are
expected at the beaches. There are chances for showers and
thunderstorms starting early next week.

Short term (this evening through Saturday)
issued at 306 pm edt Fri aug 23 2019
quiet weatherwise for the short term. Surface high pressure with an
upper level trough overhead will keep conditions cooler and dry
through Saturday. Lows tonight will be in the 50s. Highs Saturday
will be in the 70s.

The main concern will be gusty winds out of the north-northeast
over lake michigan this afternoon and evening. Wave heights have
lingered between 2-3 feet throughout the day thanks to NE ene
flow, but now that flow has become more nne they've climbed to
nearly 4 feet in laporte county. Expect them to linger between 3
to 5 feet through the evening. Wave periods range from 5 to 6
seconds and waves are approaching beaches at a 30 to 60 degree
angle, especially further south in laporte county, in. This means
strong longshore structural currents are expected to continue. Rip
currents are possible at beaches where flow is more direct.

Berrien county, mi beaches will see moderate swim risk conditions,
with more of a shore-parallel flow expected (and thus less
chances for offshore-flowing currents). Maintained the going
marine headlines with laporte in a beach hazards statement high
swim risk until 3z, and berrien under a moderate swim risk. A
small craft advisory remains in effect for waters along laporte
county as well.

Winds become more easterly tonight and lighten up, lowering wave
heights. Beachgoers should be mindful of offshore winds this
weekend, however-which can blow rafts and flotation devices away
from the beach.

Long term (Saturday night through Friday)
issued at 306 pm edt Fri aug 23 2019
upper level ridge builds in Saturday night and lingers through
Sunday night, with surface high pressure in place. This will keep us
dry, with clear to partly cloudy skies. Saturday night lows will be
in the 50s. Highs on Sunday will climb into the mid-upper 70s and
low 80s. Expect increasing clouds with lows in the 60s Sunday night.

Our next chance for rain will be Monday into Tuesday night as an
upper level low swings through the canadian prairies and brings a
trough across the midwest into the great lakes region. The GFS is
stronger and further south with the trough upper low, and this
results in a more intense surge of moisture warm air streaming from
the southwest Monday and Monday night (pwats up to 2.07 inches by
mon eve). So we'll see some precipitation on Monday, especially
towards the afternoon hours. The cold front from the surface low
then passes through on Tuesday, approaching the doorstep of our
western CWA by 12z Tuesday and exiting late Tuesday night. With a
moist unstable atmosphere in place, expect we'll see thunderstorms
both Mon tue. Left the going mid-chance pops in. Highs Mon Tue will
be in the upper 70s and low 80s. Lows will be in the 60s.

Surface high pressure returns in the wake of the cold front
Wednesday Wednesday night, which leads us back to predominantly dry
weather. Aloft, we still have the surface low to the north and
depending which model you pick, either zonal flow or slight
troughing over our cwa. This always leaves us susceptible to any
minor shortwaves rippling through the flow... Possibly triggering
some isolated showers. GFS has a shortwave swing through wed
afternoon during peak heating, which could bring us a couple
showers. However, left out any pops given confidence is low at this
time.

If you follow the GFS gem, a secondary cold front moves into our
western counties late Wed night and slowly crosses the forecast area
Thursday, exiting the eastern counties Thursday evening. The ecmwf
keeps us dry Wednesday into Friday evening, then brings the cold
front along the same path as GFS gem suggest through Saturday
evening. Kept consensus low chance pops for now Wed night into
Thursday given discrepancies in timing, but expect we'll see
additional chances towards the latter half of the week.

High temperatures Wednesday into Friday will be in the 70s. Lows
will be in the 50s and low 60s.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
