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 |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus63 kmkx 161109 afdmkx area forecast discussion national weather service milwaukee sullivan wi 609 am cdt Wed oct 16 2019 Update Some lingering mist continues across parts of the CWA but should push off to the east over the next few hours. Otherwise expect breezy winds and mostly cloudy skies to continue through the day today. Aviation(12z tafs) MVFR CIGS will likely last through this morning and into the afternoon, however mixing could actually allow for a return toVFR cigs by the late morning. Otherwise we will have continuing breezy west northwest today, especially this morning, where some gusts could reach 30-35 kts. Winds will begin to die down this evening with the region expected to remain dry but clouds may stick around through the overnight period into Thursday. Prev discussion (issued 326 am cdt Wed oct 16 2019) discussion... today and tonight... Forecast confidence is high... showers have mostly pushed over the lake as the surface low has pushed to the north-central great lakes region. The very strong pressure gradient on the backside of this low will remain throughout the day allowing for very breezy winds throughout the region. However, as we push into the evening the pressure gradient will let up a bit allowing for winds to settle down. Higher pressure will also be moving in, which will allow for clouds to clear out a bit as well. This will bring some concerns for temperatures to fall to near freezing leading to some frost concerns. Otherwise, the upper level low will continue east as well. Though there will be some PVA on the back end of the upper level low there will be a relative lack of moisture depth to produce precipitation. A little upper level wave may pull through overnight Wednesday into Thursday morning bringing continuing cloud cover and maybe the possibility of an isolated shower but there may not be quite enough mid level moisture to support showers. Thursday and Friday... Forecast confidence is high. A nice couple of days here. A rather high amplitude mid level ridge will be sliding across the area, pushing east by Friday. Seasonably cool temps with a mix of clouds and Sun are expected on Thursday. But, a return southerly flow sets up on Friday with 925mb temps warming to 7-10c by afternoon. This should push highs in the upper 50s to mid 60s. The warmest readings will be found west of madison. An onshore breeze will keep it cooler across the southeast. Saturday... Forecast confidence is high. Strong low pressure will be tracking northeast across minnesota on Friday with a trailing cold front reaching our western CWA border late Friday night. Warm advection ahead of the front could bring some showers into western areas after midnight. The front will then drift through the area through early Saturday afternoon. Expect scattered showers and possibly a thunderstorm as it moves through. Since the parent low will be well up in canada by Saturday, the trailing front will be gradually weakening washing out as it reaches eastern wisconsin. |
Saturday night and Sunday... Forecast confidence is high. We should be able salvage a dry day out of this weekend. Weak high pressure will slide through in the wake of the departing trough cold front. Given that the front was mostly washing out as it exited to the east, there won't be much cold air advection in its wake, therefore, look for highs on Sunday still managing to get into the lower and mid 60s. Monday and Tuesday... Forecast confidence is medium. The models are finally getting into better agreement in handling the next storm system for early next week. A potent mid level circulation will move through the central plains to northern minnesota Sunday night through Monday. The associated strong surface low will follow a similar track to the mid level system. A strengthening low level jet by Sunday night should produce some warm advection showers and possible thunderstorms across SRN wi, though the h8 frontal boundary and better convergence should push north of the forecast area quickly during the evening. The associated cold front will likely push through the area primarily during Monday morning, exiting out over lake michigan by early afternoon. This should take the focus of heavier frontal boundary rainfall east of the area during the afternoon. A few days ago, the model solutions suggested a rather prolonged, multi-wave scenario with copious rainfall across the upper midwest wisconsin. Now, it is a rather consolidated system with the focus for heavier rainfall located to our northwest, closer to the surface low and to our east with developing afternoon convection along the front. The caveat, of course, is if the the timing and track of the low changes meaningfully, some of that heavier precip could refocus over our area. Drier and cooler air arrives for Tuesday. Aviation(09z tafs)... MVFR CIGS will continue this morning but will likely lift a bit by the late morning thus restoringVFR conditions for the rest of the day. Regardless winds will still be very strong from the west northwest with gusts up to 30 kts through the afternoon before weakening into the evening. Into the evening we also expect clouds to clear out as higher pressure pushes into the region. Marine... a gale warning is in effect for the entire lake including the nearshore areas as strong westerly northwesterly winds up to 45 kts will continue across most of the lake through the evening. The gale warning for the nearshore only carries through this morning but a small craft advisory will be needed once the gale warning is expired as winds will still be quite breezy. The pressure gradient will weaken into this evening as the low pressure system pushes further east, which will allow winds to fall off into the evening. Higher pressure will then allow winds to remain lighter through at least Thursday. Mkx watches warnings advisories Wi... None. Lm... Gale warning until 7 pm cdt this evening for lmz080-261-362-364- 366-563-565-567-669-671-673-675-777-779-868-870-872-874-876- 878. Gale warning until 2 pm cdt this afternoon for lmz643>646. Update...

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. |
