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.

SHORT TERM. (Through Late Saturday Afternoon) Issued at 321 AM CST Fri Jan 22 2021
Back to near normal or just a bit below normal temperatures through Saturday as surface ridge builds into region today. Despite mostly sunny skies today, northerly winds and decent CAA will cause temperatures to continue falling through the morning hours before rising a bit during the afternoon. Highs will range from the mid 20s far north to the low 40s far south.
With surface ridge overhead tonight, as well as clear skies and light north to northeast winds, temperatures will fall into the low teens to around 20 degrees.
On Saturday, surface ridge will move off to our east allowing winds to veer to the southeast to south once again. Temperatures will moderate just a bit with highs in the low 30s to low 40s.
LONG TERM. (Saturday Night through Thursday) Issued at 321 AM CST Fri Jan 22 2021
More active weather pattern in store for the region beginning Saturday night. Deepening upper level trough over the southwestern U.S. as well as deepening system over the central Canadian provinces will begin to affect the central portions of the country. For our region, the main influence with be the system over the southwestern U.S.
By Saturday night, associated surface system over eastern Colorado will begin to slide southeast into OK panhandle. This will allow a developing warm front over forecast area to lift northward, so temperatures will be steady or slowly rise during the overnight hours. In the meantime, increasing moisture advection on the nose of a southwesterly low level jet combined with the WAA will allow precipitation to develop across the forecast area. A mixture of light rain, freezing rain, sleet, and snow is expected with evaporative cooling enhancing nocturnal cooling as the precipitation initially falls into a very dry boundary layer, especially along and north of I-70, with minor ice and snow accumulations expected.
On Sunday, the precipitation should gradually change over from a wintry mix to liquid rain from south to north, and taper off, as the surface temperature warms into the 40s across most of our area.
More significant precipitation is expected Sunday night through Monday evening as southern stream trough lifts northeastward towards region. Associated surface low will slide east northeast through southern Missouri during the day on Monday. As it moves through region, there will be plenty of low level Gulf moisture advecting in. Sunday night precipitation will initially start out as mainly rain except for the far northern portions of the forecast area where a wintry mix will develop, so will see minor snow and ice accumulations in this area. Then as system exits region Monday afternoon/evening, a number of models are hinting at a deformation zone setting up, mainly along and north of I-70, with colder air filtering in and rain changing to snow, with 1 to 3 inches of accumulation possible over portions of northeast Missouri and west central Illinois, with lesser amounts south.
The precipitation will taper off to flurries late Monday night. Beyond that, could see another round of activity Wednesday afternoon through Wednesday night.
AVIATION. (For the 12z TAFs through 12z Saturday Morning) Issued at 538 AM CST Fri Jan 22 2021
Surface ridge will continue to build in across the region with just some high thin cirrus overhead today. So VFR flight conditions through the forecast period with north winds becoming light and variable after 00z Saturday.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerous of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
