Marine Weather and Tides
Version 3.4 |
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues. |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kbuf 201846 afdbuf area forecast discussion national weather service buffalo ny 246 pm edt Wed jun 20 2018 Synopsis Expect some sprinkles south of lake ontario through mid afternoon with some rain showers across the southern tier as a weak wave of low pressure tracks to our south. A weak cold front will cross the region tonight with high pressure building through the end of the work week, brining dry and comfortable conditions. A storm system will approach for the weekend bringing rain showers and some rumbles of thunder, mainly Saturday, with a few showers lingering into Sunday. Near term through Thursday A weak shortwave and attendant surface low tracking through the northern ohio valley and into pa today will bring a wealth of mid and high level cloud cover across the region. A layer of very dry air near the surface per the 12z buf sounding will preclude much precipitation today, keeping us mainly dry. However, a period of moderate rain aloft through early afternoon will allow for some scattered sprinkles south of lake ontario and showers across the southern tier to actually make it to the surface. Measurable precipitation of less than an tenth of an inch will be limited to the southern tier. Any showers or sprinkles will quickly taper off from west to east by mid to late afternoon, leaving us a completely dry evening. An important note, the radar will likely appear much more ominous than precipitation will actually be today, since it will be seeing the rain aloft, however much of this will evaporate before actually reaching the surface. Otherwise, light winds, cloud cover, and temperatures only in the low to mid 70s will actually make for a fantastic and comfortable day for outdoor activities. A surface high will push toward southern ontario canada tonight. Meanwhile a shortwave rounding a longwave trough over eastern canada will drive a backdoor cold front across quebec, northern new york and new england tonight. Shower activity along this front will remain near the upper level support well outside the forecast area, though a stray shower or two may clip eastern jefferson northern lewis counties. Lows tonight will drop back into the 50s with a light wind. High pressure will continue to build across the region Thursday with mainly clear skies and light northerly winds advecting in a cool and dry canadian airmass. The result will be a phenomenal june day with highs in the low to mid 70s and very low humidity. Short term Thursday night through Saturday night A nearly stacked low pressure system will move into the ohio valley while high pressure slowly moves off the gulf of maine Thursday night. Mostly clear conditions will continue Thursday night as moisture stays confined southwest of the forecast area. Moisture will begin to enter the region Friday and into the weekend as high pressure moves off the northeast coast and low pressure progresses eastward. Low pressure will advance eastward Friday while a warm front approaches the forecast area. Winds aloft will veer from the southeast to south causing moisture to advect into the forecast area. Overrunning will cause clouds to increase from south to north Friday and light-intermittent rain will likely spread across western ny through the afternoon. Since a dry airmass will still have its hold on the region Friday, rain will be light and may only account to trace amounts. Warm air advection ramps up Friday night as 850mb winds increase to 30kts and the warm front moves into western ny. Rain will increase in coverage as the stacked low pressure system moves near western lake erie by Saturday morning. As the warm front moves northward and into the north country Saturday, 65-70 deg dewpoints will spread northward while a shortwave trough rounds the base of the low |
pressure system. This will lead to more widespread showers and the chance for thunderstorms. At this time, the area from the southern tier to the southern shore of lake ontario has the best chance for thunderstorms through Saturday afternoon. As the shortwave trough moves eastward into Saturday night, the chance for thunderstorms will expand into the north country. Temperatures will be near normal Thursday night-Friday and become above normal through the weekend. Long term Sunday through Wednesday An exiting low pressure system will drag the first of two cold fronts thorugh our region on Sunday. While the majority of the day will be rain free... There will be the potential for some showers and even a thunderstorm. A secondary cold front is then expected to make its way through our area Sunday night... But with a lack of instability and less forcing... Will only carry a minimal chance for a few more showers. Medium range guidance is now suggesting the passage of a fairly strong shortwave late Sunday night or early Monday. Will increase the sky cover from continuity... And also add slgt chc pops for the north country... To cover this potential. Otherwise... Monday should feature pronounced improvement over the weather from the weekend as we will return to at least partial sunshine with much more comfortable conditions. The next area of canadian based high pressure will make its way across the lower great lakes Monday night before settling to our southeast on Tuesday. This will promote beautiful weather across our region with mainly clear skies and pleasant temperatures and humidity levels. Aviation 19z Wednesday through Monday WidespreadVFR conditions will prevail today. Scattered showers and sprinkles are expected south of lake ontario, however these will fall from a 5-10kft deck with vsbys 6 sm or greater. Any showers will end later this afternoon and evening, with otherwise dry conditions and light winds prevailing. High pressure will maintain fair weather andVFR conditions through Thursday. Outlook... Thursday night through Friday...VFR. Saturday...VFR MVFR... Showers and thunderstorms likely. Sunday... MainlyVFR. A chance of showers and thunderstorms. Monday...VFR. Marine A weak cold front will cross the lower great lakes tonight with northeasterly winds increasing behind the front, however conditions will remain below sca. High pressure will build across the lakes for the end of the work week with optimal boating conditions. A low pressure system will pass near the lakes over the weekend brining more unsettled weather, however winds and waves are expected to remain below SCA at this time.

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. |
