Marine Weather and Tides
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.

SYNOPSIS. Issued at 319 AM CST Sun Jan 17 2021
A upper level Low pressure system will shift through north central Illinois this morning, bringing snowfall to much of the region. Some early morning freezing drizzle will be possible, mainly north of the I-74 corridor, through the early morning. Heaviest amounts of snowfall will remain along and north of I-74, as the convective band of snow tracks se through north central Illinois. Snow flurries will continue tonight, before a chance for drier conditions arrives Monday morning. This dry period will be short lived, as another weak disturbance slides through south central Illinois Monday night, bringing additional precip chances to locations between I-64 and I-74.
SHORT TERM. (Today and tonight) ISSUED AT 319 AM CST Sun Jan 17 2021
An upper level Low pressure system is situated, early this morning, over DVN. This will slowly track ese through the morning, bringing the chance for accumulating snowfall to much of central Illinois today. Numerous reports of freezing rain/drizzle have been coming out of locations across north central Illinois, with a Winter Weather Advisory hoisted by DVN during the overnight. In our CWA, the only locations that have the chance for this precip would be mainly across the far northern tier of counties, however with temperatures in the mid 20s, expecting this to be snowfall, so did not issue any products. Currently on radar, a deformation zone of accumulating snowfall and reduced visibilities has setup across northern Illinois, just outside the ILX CWA. This zone is expected to remain north of the area, holding the highest amounts of snowfall outside the local coverage area. The southern edge of the Low will track through the northern CWA, along I-74, and is forecast to remain north of the I-74 corridor through the day. This will bring the best chances for snowfall across the local area to the I-74 corridor.
As this system slides out of the area overnight, lingering flurries are anticipated, as the continuation of nw-se/zonal flow brings weak moisture and waves through the Midwest.
LONG TERM. (Monday through Saturday) ISSUED AT 319 AM CST Sun Jan 17 2021
Heading into the start of the new work week, a brief period of dry weather is expected during the start of Monday. Unfortunately, with the zonal flow remaining overhead, this will bring additional chances of light moisture to the Midwest. The first chance during the week comes Monday evening into the overnight. High pressure across se US and Low pressure in the northern Great Lakes will squeeze moisture as a weak upper wave glides through central and southern Illinois. This will bring mixed precip to the region, as temperatures will be near freezing in the lower level. This should remain south of the I-74 corridor, mainly impacting locations between I-72 and I-64, before quickly exiting Tuesday morning.
The northern jet stream flattens heading through Tuesday, which will elongate and weak the zonal wave pattern in the upper levels. This will bring a stretch of dry conditions to the Midwest through much of Wednesday. While this is ongoing, a strong Low pressure system will stall out across the desert sw as the jet does not allow northward progression. This Low will create the elongated/zonal flow that will also prevent any storms from dropping into the mid-latitudes through mid-week . as indicated by models holding a large-scale Low pressure across southern Canada into the far northern Great Lakes region.
Finally the Low shifts out of the region, as the northern jet starts dropping another Low pressure system and associated trof along the western coast. Bad news for this southern tracking Low, as the upper level Low across eastern Canada slowly tracks eastward, inching a trof system southward. As this pushes southward, it will inhibit any northward progression of the southern tracking Low. This Low will ingest moisture from the Gulf, however it will not be able to lift through the northern systems grip . continuing the mostly dry conditions across the region. Some light precipitation could slide into the Ohio River Valley region, maybe as far north as southeast Illinois, but models seem to be a little eager with the northward fetch.
Slight ridging is being shown currently in model trends for late Friday into Saturday, continuing the dry conditions into the start of next weekend.
Temperatures will be a little up and down this week, as the upper level pattern gives the jet streams a little movement. Temperatures are forecast to remain steady through the first half of the upcoming week, before an increase mid-week and Thursday. However, behind the expected dry frontal system Thursday, temperatures dropped back to near normal for the time of year.
AVIATION. (For the 06Z TAFS through 06Z Sunday night) Issued at 1131 PM CST Sat Jan 16 2021
MVFR cigs are in place across most of the central IL terminals, expected to decrease slowly into IFR along the I-74 terminals overnight. Meanwhile, increasing coverage and rates of snowfall should continue as another disturbance moves into the area. This snow should bring general IFR to MVFR vsbys, as well as an end to patchy freezing drizzle. Potential LIFR cigs/vsbys possible in heavier snow showers. Light snow should begin to taper off from west to east from 21Z- 03Z. Winds W 7-12 kts through the period.

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.
