Marine Weather and Tides
Version 3.4 |
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. 6/2/2019. Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working. I fixed many but I still depend on users to report ones I missed. Please report errors HERE or send an email to me at L-36.com. Allen |

Prev Discussion. /issued 308 AM EST Sun Dec 8 2019/
DISCUSSION . High amplitude U/L pattern over much of North America with a sharp ridge along the west coast of the U.S./Canada will induce a deep trough downstream . with cold arctic air being pulled south over the upper Mississippi Valley and midwest. A southern stream disturbance will push across the southern plains on Tuesday . the Lower Mississippi Valley on Wednesday . and will then be sheared out as it moves across the southeast U.S. Wednesday night and Thursday.
Significant pattern change mid/late week as the west coast ridge breaks down and strong quasi-zonal flow develops. A southern stream disturbance will push across the southern plains on Thursday . and the Lower Mississippi Valley on Friday. Southern stream disturbance will come in phase with the northern stream late in the week carving out a deep progressive U/L trough from the Great Lakes to the Gulf of Mexico. The trough axis will rotate and lift northeast off the eastern seaboard over the weekend with quasi-zonal flow across the CONUS in its wake.
Surface high pressure will hold over west central and southwest Florida through Tuesday. The first southern stream disturbance will move across the southeast on Wednesday with a chance of showers developing Wednesday and persisting into Thursday. Associated cold front will stall across north Florida with cooler air only advecting across northern portions of the nature coast . with the remainder of west central and southwest Florida remaining in the warm sector. Second S/W disturbance will move across the southeast U.S. and Florida Friday and Friday night. Overall dynamics will be stronger than the initial disturbance with scattered showers and isolated thunderstorms expected Friday and Friday night. Shower activity will end from north to south as a cold front moves across the region. Cooler drier air will advect across the region in the wake of the front over the weekend, however temperatures will only drop back to near climatic normals.
MARINE . No hazards expected through midweek with relatively light winds and seas. Lead cold front will stall across the northern waters Wednesday night and Thursday with SCEC or SCA conditions possible over portions of the northern waters behind the frontal boundary. SCEC conditions possible over most of the waters late in the week and early Saturday associated with the second cold front.
FIRE WEATHER . No fire weather hazards are expected for the next several days as relative humidity values are expected to remain above critical levels.

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. |
