Fxus63 kiwx 231910 afdiwx area forecast discussion national weather service northern indiana 310 pm edt Fri aug 23 2019 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.
