Lake superior from grand marais mi to whitefish point mi 5nm off shore to the us/canadian border... Marquette to munising mi... Munising to grand marais mi... At 357 pm edt...doppler radar indicated numerous Thunderstorms... Capable of producing winds to around 30 knots. These Thunderstorms were located along a line extending from 8 nm north of laughing whitefish point to 17 nm north of miners castle to 8 nm west of grand sable dunes...moving northeast at 50 knots. Precautionary/preparedness actions... Mariners can expect gusty winds to around 30 knots...locally higher waves...and lightning strikes. Boaters should seek safe harbor immediately until these storms pass. && lat...lon 4676 8506 4676 8522 4671 8524 4664 8548 4663 8615 4653 8642 4637 8665 4643 8677 4640 8690 4649 8703 4646 8719 4662 8722 4752 8640 4689 8486 4681 8483 |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus63 kmqt 240800 afdmqt area forecast discussion national weather service marquette mi 400 am edt Sat jun 24 2017 Short term (today and tonight) issued at 359 am edt Sat jun 24 2017 water vapor imagery shows a weak shortwave pushing east across the area early this morning, with another more potent upper-level wave rapidly digging across the northern plains through north dakota and into minnesota. A few scattered showers associated with the first weak shortwave have developed across the west. The initial shortwave moving across the area will prime the mid levels and allow for lingering mid-level moisture to remain in place ahead of the stronger trailing upper-level wave. As this wave dig south of the area across wisconsin, a narrow area of ample upper- level divergence should allow for showers to become more widespread this afternoon, especially across the central portions of upper michigan. As previously mentioned, freezing levels will begin to lower to near 6000-7000ft agl, but with weak shear across the area and skinny CAPE profiles showing rather limited amounts of instability, think that any stronger updrafts will struggle. Tonight as the main upper-level wave lifts out of northeast wisconsin and across lower michigan, lingering showers and thunderstorms will continue, especially across the central and east. Long term (Sunday through Friday) issued at 300 am edt Sat jun 24 2017 beginning sun, the approach of another shortwave combined with daytime heating will yield numerous afternoon showers inland from lake superior. Coverage should be least over the eastern part of the fcst area due to greater stabilization from flow off lake superior in that area. With MLCAPE into the 500-900j kg range, expect at least isold-sct t-storms as well. Low wetbulb zero heights in the 5.5-6.5kft range under weak shear environment suggest there could be a lot of cells producing small hail Sun afternoon. Showers will again diminish Sun night with loss of daytime heating. Highs on sun will be in the 60s, coolest near lake superior. On mon, heights will begin to rise as the mid-level trough begins to shift e. However, lingering cold pool aloft and some build up of instability, should yield isold to sct -shra inland from lake superior, especially over the S central where the more limited mlcape of 200-300 j kg will be centered. Temps could be a few degrees higher than sun, but will still be mainly in the 60s. Tue should be a pleasant day as the sfc high pres ridge passes over the area. Under mostly sunny skies, temps will rise into the 70s |
across the area, locally cooler along the great lakes. Wed thru Fri looks to be an active period as a mid-upper level trough developing into the northern rockies slowly shifts e. Wsw flow and at least a couple of shortwaves ejecting from the trough into the western great lakes will generate showers t-storms with probably some risk of severe storms given strong deep layer shear and periods of increased instability. There is reasonable model agreement for a better potential of showers t-storms Wed wed night and possibly severe storms. Model agreement diminishes drastically thereafter on timing of shortwaves, but it appears there will be another round of showers t-storms at some point Fri sat. Aviation (for the 06z tafs through 06z Saturday night) issued at 120 am edt Sat jun 24 2017 late tonight through Saturday morning, a weak surface trough and upper level disturbance will approach the area. This will bring increasing rain chances and CIGS dropping into the MVFR range. However, visbility should remainVFR even under some of the rain showers. Marine (for the 4 am lake superior forecast issuance) issued at 359 am edt Sat jun 24 2017 winds of 10 to 15 knots are expected to continue through the first half of next week as the pressure gradient decreases and high pressure builds in for the first part of the work week. Towards the middle of the week, winds will start to increase to around 20 to 25 knots as a system lifts across the upper great lakes. Winds will then decrease to around or less than 15 knots towards the end of the week and next weekend. Mqt watches warnings advisories Upper michigan... none. Lake superior... none. Lake michigan... none. Short term... Ritzman long term... Voss aviation... Jlb marine... Ritzman |

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. |
