Marine Weather and Tides
Version 3.4 |
8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it. 8/18/2020 NOAA continues to have trouble. Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue. 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. |

Area Forecast Discussion National Weather Service Northern Indiana 633 AM EDT Fri Sep 25 2020
SYNOPSIS. Issued at 355 AM EDT Fri Sep 25 2020
Expect warm conditions these next few days with high temperatures near 80 degrees for most locations. It will turn notably colder early next week, paired with periodic rain chances.
SHORT TERM. (Today and Saturday) Issued at 355 AM EDT Fri Sep 25 2020
A trough will work its way eastward through our area over the next 24 hours. As it does so, warm air advection at 850-mb ramps up. This will allow temperatures to warm to near 80 degrees for much of the CWA. The Gulf of Mexico remains off-limits to our area, thus keeping things dry, due to a surface low tracking through the Southeast U.S.
WAA continues through Saturday, pushing high temperatures a few degrees warmer than Friday. From 12z Friday to 00z Sunday, 850-mb temperatures will warm from about 12C to 22C; pretty impressive for late September. Winds will pick up a bit through the day Saturday, with wind gusts near 20-25 mph as a surface low approaches the western Great Lakes.
LONG TERM. (Saturday night through Thursday) Issued at 355 AM EDT Fri Sep 25 2020
We'll remain in the warm sector of a surface low forecast to lift northeast toward the Hudson Bay on Sunday, which means we'll be on track for another day with highs near 80. Since last week, the forecast for this whole system has really slowed down. A glimmer of forecast confidence this morning is that the 00z GFS and 00z ECMWF are in agreement for the overall 500-mb height pattern. However, the ECMWF has a more portent surface low.
As this low wraps-up over the Hudson Bay, a cold front moves through our area and huge trough takes shape over the Central US. This pattern opens up our access to some Gulf Moisture, and thus the best chance for rain we've seen in nearly two weeks. This of course will erase highs in this 80s; say hello to highs in the 60s on Monday (NW Ohio could sneak into the 70s, especially if this system continues to slow down).
The mid-and late-week forecast is rather murky with either a surface low tracking through the mid-Mississippi River Valley (GFS) or a cut- off low swirling over Louisiana, then lifting north (ECMWF). Therefore, broadly speaking, the forecast will consist of cooler- than-normal temperatures, periodic chances for rain showers (especially toward the lake, and in the northern counties), and even gusty winds and high waves on Lake Michigan.
AVIATION. (For the 12Z TAFS through 12Z Saturday Morning) Issued at 628 AM EDT Fri Sep 25 2020
VFR conditions are expected to persist throughout this forecast valid period. Sfc anticyclone will gradually lose its influence across northern Indiana into tonight. Calm winds this morning will become light south-southeasterly with speeds to around 10 knots this afternoon. Some light southerly flow to persist tonight as low level gradient begins to strengthen. Higher res guidance does indicate some northward advance of stratus across the Ohio Valley late in the period, but would suspect greater chances of patchy MVFR cigs will remain south of the terminals into southern Indiana/southern Ohio Saturday morning.
