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. Scattered showers will end this evening as high pressure builds in, leading to a sunny but still cool Saturday. A cold front will bring rain showers Sunday, and a shot of cold air behind the front will change precipitation to snow showers Sunday night into Monday morning. Drier weather and a warming trend will follow.
NEAR TERM /THROUGH TONIGHT/. Passage of a mid-level shortwave trough will soon lead to an end of the more concentrated shower activity. However, northwest flow, cold advection, and mid-level vorticity will help to keep isolated/scattered showers going into the evening hours, possibly through midnight along the higher terrain. As the boundary layer cools, some snowflakes will start to mix in this evening before precipitation ends, and even a very brief period of light freezing drizzle is possible on the higher Tucker County slopes due an eventual lack of deep moisture/ice crystals. No significant impacts are expected from any of this precipitation.
Overnight, some clouds are likely to linger as some moisture remains under a subsidence inversion, although clearing is possible toward morning as surface high pressure centers itself over the region. Along with nearly calm wind, a period of radiational cooling is expected towards dawn. With temperatures dropping into the mid and upper 20s across a large part of the region, some of the coldest readings of the season so far will be observed.
SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/. Dry weather will continue through Saturday night as the surface high departs. Southerly flow will pick up by afternoon as the pressure gradient tightens between the high and a low center passing north of the Great Lakes. Warm advection will commence by afternoon, but it will likely be too late to allow temperatures to rise more than a few degrees higher than today. However, Saturday night will not be quite as chilly thanks to an increase in that warm advection as well as cloud cover behind a warm front. Low temperatures should improve on Saturday morning values by roughly 10 degrees.
On Sunday, a sharp upper trough will advance from the Upper Midwest/Great Lakes and into our region, with an accompanying cold front crossing during the day. Precipitation chances will return during the day, with highest PoPs near/north of I-80 thanks to eventual lake enhancement. Daytime highs will likely be established during the late morning/early afternoon before temperatures start to drop behind the front, and wind gusts will also increasing in the steepening lapse rates behind the boundary.
A changeover to snow will commence later Sunday afternoon as 850mb temperatures plunge to -8C/-9C, with the transition completing during the evening as surface temperatures fall through the 30s. The initially warm ground will help to limit accumulation in some cases. However, model soundings are showing saturation at least into the dendritic growth zone, along with decent lapse rates and modest CAPE. This is summed up with BTV snow squall parameters showing decent values at least across the northern counties on the GFS, and in a more widespread manner with the NAM. Think that accumulations of an inch or two will be possible Sunday night into Monday morning mainly north of I-80 and in the higher elevations of Garrett/Preston/Tucker, with less than an inch elsewhere. Would not rule out isolated higher totals if heavier snow showers/squalls are realized.
LONG TERM /MONDAY THROUGH THURSDAY/. A few snow showers will linger into Monday morning, mainly in the ridges, as the 850mb thermal trough moves through. Snow showers should then largely cut off by midday Monday thanks to low-level flow backing towards the west. Afternoon clearing will not help temperatures rise much above the 40-45 degree range, with 30s in the higher elevations.
Thereafter, surface high pressure slowly tracks from the lower Mississippi Valley and across the southeast CONUS through the rest of the week. A flattening ridge aloft will move into the region and hold through the week, keeping our weather dry. Temperatures will show a warming trend with time thanks to southerly flow and rising mid-level heights, with afternoon highs eventually poking back above normal by the end of the week.
AVIATION /16Z FRIDAY THROUGH TUESDAY/. Light scattered shower chances will continue today with a passing trough and lingering low-level moisture; prevailing MVFR conditions for most sites with cold advection/NW flow. Cigs will gradually lift by late evening as dry air advances into the region. Periods of broken MVFR overnight at DUJ/FKL may be experience due to lake enhanced moisture.
Outlook. Restrictions are likely Sun and Mon with a crossing cdfnt, and subsequent cold NW flow and upper troughing.

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.
