6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported. 5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive. 5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds. |

Waves are provided as a range of significant wave heights, which is the average of the highest 1/3 of the wave, along with the average height of the highest 10% of the waves which will occasionally be encountered. .SYNOPSIS...High pressure of 30.2 inches over New England will slowly move off the east coast Wednesday night. Meanwhile, low pressure of 29.5 inches over northwest Ontario will move east to James Bay by Wednesday evening. A trailing surface trough will slowly move south over the northern part of the lake Wednesday evening. Another low pressure around 29.8 inches will develop along this trough, just south of Lake Michigan Wednesday night, and move east to the Mid Atlantic by Thursday night. High pressure of 30.1 inches will build over the lake by Friday night and hold through the weekend. LMZ261-362-364-366-563-565-567-868-260800- |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus63 kapx 260400 afdapx area forecast discussion national weather service gaylord mi 1200 am edt Wed jul 26 2017 Update Issued at 1015 pm edt Tue jul 25 2017 strengthening warm moist advection is edging ever closer to northern mi this evening. Upstream activity was struggling to make eastward progress before, but leading edge of more organized activity has reached the west short of lake mi, on up to mqt. A still-increasing low level jet will continue to push a richer airmass into the region. That all said, at the moment the airmass over our head is not supportive of deep convection, thanks to a warm dry capping layer at 800-700mb (per 00z apx sounding). Moistening this will take a good chunk of the night. So this first wave of convection will still tend to weaken as it moves in, though it will bring sct precip to western northern sections. Better heavier rain chances will not arrive here until after 4 am, mainly for eastern upper and far NW lower mi (where the 850mb theta-e ridge folds into). Some fine-tuning of pops and cloud timing in order, with a general trend to boost pops somewhat overnight (especially late). Near term (today through tonight) issued at 352 pm edt Tue jul 25 2017 Increasing shower chances tonight... high pressure will continue to provide dry conditions thru this afternoon, but with the high sliding southeast overnight clouds will increase from the northwest to southeast with increased chances for showers and possibly an embedded thunderstorm late tonight closer to daybreak Wednesday. Short term (Wednesday night through Friday) issued at 350 pm edt Tue jul 25 2017 trough of low pressure will skirt the northern great lakes wed, with the frontal boundary sagging south across the forecast area. But with a somewhat progressive flow, the boundary will continue to push south by thur morning as yet another ridge of high pressure builds in from the northwest. This will then return dry conditions to the region thru Fri with temps becoming more seasonal in the mid upr 70s to near 80 away from the lakes. Weak pressure gradient may allow light lake breeze development, and subsequently cool areas adjacent. Long term (Friday night through Tuesday) issued at 350 pm edt Tue jul 25 2017 high impact weather potential... |
ensembles are in good agreement with ridging building across the western conus, which will keep the great lakes region in a quasi- northwest flow thru the weekend into early next week. Unfortunately this also means weak lobes of vorticity can easily dive southeast and bring a chance for showers and possibly a thunderstorms. Presently operational solutions indicate dry weather sticking around through sat; however, the latest GFS does suggest a weak vort trying to slide across the northern great lakes Sat and could bring a brief chance for showers. But have presently discounted this scenario and maintained a dry forecast. Aviation (for the 06z tafs through 06z Wednesday night) issued at 1156 pm edt Tue jul 25 2017 llws tonight. MVFR CIGS reaching pln Wednesday afternoon. High pressure near lk ontario will move east, allowing a weak cold front to cross northern mi Wednesday night. Shower thunderstorm activity has already arrived in NW lower mi, and will increase further ahead of the front. Lower CIGS will arrive in the vicinity of the front, the pln the 1st to see MVFR CIGS later on Wednesday. S to SW winds, somewhat gusty on Wednesday. Llws tonight, with strong S to SW winds just off the surface. Marine Issued at 352 am edt Tue jul 25 2017 light winds this morning will give way to increasing southerly flow later today and particularly tonight...

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. |
