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. Snow showers will end this afternoon, but gusty wind will linger into early evening. High pressure will provide dry weather tonight and Saturday, with the beginning of a warming trend. Rain chances begin to increase on Sunday with approaching low pressure.
NEAR TERM /THROUGH TONIGHT/. Snow shower intensity has decreased as support for lift has waned due to the departure of a mid-level shortwave. Continued northwest flow is allowing for continued Lake-Erie enhanced snow showers. These will continue to decrease in coverage/intensity this afternoon with the departure of the 850mb thermal trough and the approach of surface high pressure, with activity expected to cease by late afternoon/early evening. Wind gusts of 30-40 MPH, higher in the Wind Advisory area, will continue into the early evening before a slackening surface pressure gradient and decreased mixing allow the wind to relax.
Some of the cloud cover will linger after sunset as moisture remains trapped underneath a subsidence inversion, but a mostly clear sky will develop overnight as low-level ridging builds. This will allow temperatures to dip below freezing once again across the region.
With the implementation of a new frost/freeze program, to help better determine the start of the growing season, a freeze warning has been issued for a portion of the southern border.
SHORT TERM /SATURDAY THROUGH SUNDAY/. Saturday will begin mostly sunny as the low-level ridge axis passes, although mid and upper level clouds will increase during the afternoon. With low level flow turning towards the southwest during the afternoon, warm advection will push temperatures into the lower and mid 50s for many areas, which is closer to but still a bit below seasonal norms.
500mb heights will continue to rise through Sunday in response to a deepening trough moving across the southern Rockies and Plains. This will allow for continued warming, with highs reaching well into the 60s. Continued moisture increase and slowly building warm advection-induced lift will lead to some spotty light rain starting later Saturday night, with a bit better coverage on Sunday.
LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/. The southern stream shortwave will eject northeast across the Mississippi Valley Sunday night and cross our region on Monday. There is some question as to how efficiently this wave will phase with northern stream energy on Monday morning. Still, it appears likely that strong cyclogenesis will occur, leading to a surface low track across the Great Lakes Monday morning which will push a cold and/or occluded front across the CWA. A good slug of rainfall is expected Sunday night ahead of the cold front. A moist airmass (1.2 to 1.4 inch PWAT) along with upper support/coupled jets will support a period of moderate to heavy rain. An inch or more is possible during the Sunday night/Monday period.
A potentially larger impact may be felt by widespread strong wind. Based on a local study, this event has many of the characteristics of a widespread event, such as the Great Lakes low track, a negatively tilted 500 mb trough, and the favorable positioning of mid and lower level jet streaks. Wind headlines look like a good bet for Monday, and would not be surprised if High Wind Warnings are eventually needed for at least a portion of the area.
Behind this system, lingering troughing will provide below normal temperatures and a few chances for showers through the rest of the week.
AVIATION /19Z FRIDAY THROUGH WEDNESDAY/. Dissipation of isolated snow showers is expected this aftn with increasing subsidence and building high pressure, with diurnal mixing resulting in VFR conditions. A tight sfc pressure gradient plus deep mixing will keep gusty NW wind until this eve, with 25 to 35kt gusts possible.
High pressure and decoupling will help wind relax overnight and generally clear skies, though some residual trapped beneath an inversion may keep sct/bkn mid level clouds. Warm advection aloft will further increase mid/upper level cloud coverage late in the day Saturday.
Outlook. Restrictions are likely Sun and Mon with crossing low pressure.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
