Marine Weather and Tides
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed.
10/9/2019 Updated the Marine Zones.
9/4/2019 Fixed the weather maps due to NOAA moving them.
7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports.

UPDATE. The AVIATION Section has been updated below.
SYNOPSIS. Issued at 352 AM EDT Sat Aug 15 2020
There will be a few instances of marginal chances for showers and thunderstorms today through Monday. Any prolonged, organized thunderstorm during this time period could produce a severe wind gust, although this will be very isolated. Temperatures will cool down following today as a succession of cold fronts will pass through tonight and Monday. Throughout the long term conditions look to be cool and dry.
NEAR TERM /Today/.
Issued at 352 AM EDT Sat Aug 15 2020
Near surface saturation thanks to clear skies and higher moisture content has positioned central Indiana in a semi-favorable set up for fog formation early this morning. Main area of concern will be over western and northern portions of the region where temperatures remain low and winds are calm. Current satelitte imagery does not show much fog formation yet, and therefor expectations have been lowered. Visibilities less than 1 mile should be isolated. By mid morning, any lingering fog should dissipate.
With mostly clear skies, temperatures should warm substantially in the midst of peak solar heating. Expect highs this afternoon to be in the upper 80s. Precipitation chances will increase in the east later this afternoon as the boundary layer destabilizes and promotes isolated diurnal convection. Easter portions of the region are positioned within a slightly more dynamic regime, explaining the increase in PoPs over this region.
SHORT TERM /Tonight through Monday Night/.
Issued at 352 AM EDT Sat Aug 15 2020
The main focus during the short term will continue to be on the passage of an upper level wave late Saturday night into Sunday. This wave will pass over the Great Lakes, keeping the strongest upper level support away from central Indiana. Cooler air behind this wave looks to breach central Indiana Saturday night. This in conjunction with a moderate warm sector will create a weak surface boundary, providing some lift as it passes through Indiana. As this front moves through, isolated thunderstorms will be possible. Depending on the timing of convective initiation later today, some thunderstorms over northwest potions of central Indiana could maintain themselves long enough to organize and produce severe wind gusts. Confidence in any thunderstorms reaching severe criteria is low at this time.
The lack of sufficient upper level forcing will cause the boundary to stall over central Indiana, keeping eastern portions of the state in the warm sector on Sunday. This sector will also have slightly higher moisture content allowing for additional diurnal convection in the afternoon and evening. Convective development should help move the boundary east of central Indiana by Sunday night, dropping any chances of precipitation.
A secondary cold front will pass through northern central Indiana on Monday, providing another slight chance of showers and thunderstorms. A more favorable wind profile for organized convection will exist on Monday, but with dew point depressions greater than 20, thunderstorm development will be isolated.
Temperatures on Sunday and Monday should be near to below seasonal given the influx of slightly cooler air. Afternoon highs will be in the low to mid 80s.
LONG TERM /Tuesday through Friday/. Issued at 328 AM EDT Sat Aug 15 2020
Fantastic late summer weather is expected next week as an amplified upper level pattern sets up across the country for much of the extended period.
A ridge will center over the Intermountain West with a broad trough aligned east of the Mississippi River. The upper trough will bring a cooler airmass into the region for next week combining with high pressure at the surface to produce an extended period of dry weather and seasonably comfortable temperatures. Highs through the period will range from the upper 70s to mid 80s with low humidity levels throughout.
As a Bermuda High sets up east of the Carolinas late next week . deeper moisture will gradually advects into the region and become more pronounced by next weekend.
AVIATION /Discussion for 150900Z TAF Update/. Issued at 425 AM EDT Sat Aug 15 2020
Made a few subtle adjustments for the next few hours based on current obs. Fog has remained localized and been slightly slower to develop. 06Z discussion follows.
Patchy fog could develop at the sites during the overnight hours. With some cloud cover in the north, lower confidence of below MVFR visibilities at KLAF. Instead have seen KBMG start to bounce a little, so will go with MVFR tempo IFR visibilities there. Some showers and thunderstorms will be possible during the afternoon and have some VCTS at the more likely western sites with that. Winds will be light and variable overnight and through much of the day. Lower ceilings will be possible tomorrow night as the next front approaches.

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.
