Marine Weather and Tides
Version 3.4 |
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 300 AM EST Mon Jan 20 2020
Cold temperatures and with light lake effect snow are expected to persist today with highs in the 20s. Lows tonight are expected to drop back into the teens. Temperatures will gradually moderate into the middle of the week, with highs near 40 degrees by Thursday. A low pressure system will then bring chances for rain and snow by Friday and Saturday.
SHORT TERM. (Today and Tonight) Issued at 300 AM EST Mon Jan 20 2020
Light/cold northerly flow will persist today into tonight on the eastern fringe of an expansive sfc anticyclone dropping southeast into the Mid MS Valley. Lake clouds in far nw IN/sw MI should expand east otherwise today with some potential for isolated to scattered flurries across northern IN and Lower MI. Whether this thin stratocu deck clears out tonight under increasing subsidence will be the key to tonight's low temperature forecast as winds become calm/variable.
LONG TERM. (Tuesday through Sunday) Issued at 300 AM EST Mon Jan 20 2020
Return flow on the backside of high pressure, and in advance of Central US height falls, will set the stage for moderating temps Tuesday through Thursday. Current expectations are for dry/stable airmass within deep layer ridge axis to provide a mostly sunny Tuesday. Clouds then likely increase into Wednesday and Thursday in wake of the ridge axis, with a very low chance for a light rain/snow mix into nw IN/sw MI on Thursday as a weak front approaches from the west.
Guidance has remained steadfast in a storm system phasing over the TN or OH Valley Friday into early Saturday. This system looks to cut- off from the polar jet which is an odd evolution for late January. This should result in light rain as the primary ptype as cold air struggles to advect into this stacked low pressure system. Continued to carry mid chance to likely PoPs and rain/snow mix wording during this time given a marginal temp profile.
AVIATION. (For the 18Z TAFS through 18Z Tuesday Afternoon) Issued at 1143 AM EST Mon Jan 20 2020
North-northwest winds aloft will continue to spread lake stratus and snow into both terminals for the majority of the 18z TAF cycle. KFWA is on the eastern edge of this stratus and could drop to MVFR briefly through 00z, but think it will remain VFR until later tonight. Light flurries will also be possible at KFWA through 00z. The main impact to the KSBN terminal so far has been an period of IFR visby due to lake effect snow while ceilings have held around 3k ft. Should see improvements in visibility as inversion heights increase through this afternoon so have gone with prevailing MVFR with a TEMPO for IFR visby for the first few hours of the TAF. After 00z tonight, should see the lake stratus move further inland as winds become more northwesterly in response to high pressure dropping southeastwards from the upper Midwest into the Ohio/Tennessee River Valley. As pressure builds during the day on Tuesday, VFR ceilings should return.

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. |
