Slightly better chance at some isolated thunderstorms tomorrow afternoon. Severe weather not anticipated. Widespread flooding still ongoing in SRN gladwin county. Pattern synopsis and forecast: upper troughing trying to slide in from the NW this afternoon, with weak vorticity swinging up through the wsw flow aloft, which has helped keep some higher level cloud passing by over NRN michigan. Meanwhile the lower clouds have continued to scour out, with some overall drier air seen on latest satellite imagery continuing to wedge into the NW cwa. The cold front that crossed us last night and this morning, was now in SE lower michigan. There have been some lingering relatively high sfc td's and bl weak convergence lake breeze tendencies that have allowed for isolated showers in ne lower, as well as in far eastern chip mack counties of eastern upper. Meanwhile, cooler air aloft with steeper lapse rates ahead of shortwave troughing was slowly making an eastward progress. There is some added moisture back behind the wedge of drier air, which hasn't fired off any showers in lake breeze convergence in south central upper michigan or western sections of mackinac county just yet. Temps were generally in the low to mid 70s and the air mass is slowly getting less humid. For the remainder of the afternoon and possibly early evening, the pattern is there for isolated showers to develop across more of interior upper michigan. A lack of instability, mlcapes not even 500 j kg, likely to keep thunder at bay. Severe weather certainly not expected. Continued mixing over the next few hours also ought to more efficiently bring down those sfc dew points to make things less humid going into tonight. Loss of heating will end any shower activity that does develop with mostly clear skies through the night and Saturday morning. Not really expecting any fog, unless we do not mix out that bl much more heading through afternoon. Then it would likely just be patchy anyway. Wind speeds Saturday afternoon will be rather marginal for good lake breeze convergence to develop, but it will certainly be hugging the shorelines more, especially in mackinac county and NE lower. Meanwhile additional weak vorticity will sweep into the region, which may help in developing isolated to scattered showers with only a handful of thunderstorms, again, instability after modifying soundings reveal up to 500 j kg. Nothing major. Can't tie all shower activity to just lake breeze convergence areas, especially with a bigger shortwave arriving into the srn lakes in the afternoon. Most of it will likely be there, but had to keep some small chance in pretty much any spot in NRN michigan. Highs in the middle 60s to lower 70s tomorrow with cooler air and likely more diurnally driven clouds. Lows tonight in the low to mid 50s. Short term (Saturday night through Monday) issued at 248 pm edt Fri jun 23 2017 Below normal temperatures with showers and a few storms... high impact weather potential... A few (largely) non-severe thunderstorms this weekend into early next week. Pattern synopsis forecast... Upper level troughiness in the process of deepening across the upper midwest great lakes region... Driven along by fairly strong short wave energy crossing the northern lakes. Cold front has pushed through much of lower michigan with cooler drier air beginning to make inroads into the region. Larger |
scale troughiness will continue to deepen through the great lakes and into the midwest ohio valley through the upcoming weekend into early next week setting the stage for another period of below normal temperatures and instability showers. Primary forecast concerns... Minimal. Secondary piece of short wave energy and weak-ish surface low over british columbia today will slide down into the region Saturday night into Sunday. Enough cool air aloft modest instability (even into the nighttime hours) and qg- forcing for ascent with this system to carry showers for all areas Saturday night. Sct-numerous showers and the chance for afternoon early evening thunderstorms for Sunday into Monday as core of coldest air aloft (now around -24c at 500 mb) slides overhead. Severe threat still appears minimal although with low wet- bulb zero heights (around 6k feet)... Pulse hail producers with the strongest updrafts will be a concern. Otherwise... Another stretch of below normal temperatures through the early part of next week... With readings a good 5 to 10 degrees below normal. Long term (Monday night through Friday) issued at 248 pm edt Fri jun 23 2017 high impact weather potential: chance of thunderstorms at various times Wednesday through Friday. Fairly progressive pattern looks to be on tap for the majority of next week with ridging aloft and surface high pressure characterizing the start of the period Monday night into Tuesday. Guidance continues to focus on a several developing areas of low pressure across the central northern plains during the middle to end of next week, ultimately renewing shower and thunderstorm chances locally as early as Wednesday through the end of the forecast period. Plenty of uncertainties remain at this juncture, but confidence is growing in periods of wet weather returning during the second half of next week across northern michigan. Aviation (for the 18z tafs through 18z Saturday afternoon) issued at 1246 pm edt Fri jun 23 2017 still some spotty low cloud MVFR ifr out there, but it seems to be mixed out thin enough at the airports to be taken out of all tafs, even as a temporary conditions. Quite a bit of garbage high cloud out there, which will be mixed in with scattered cumulus for the afternoon. Maybe some spotty CU lingering around tonight and continuing into tomorrow, when also, scattered rain showers and an outside chance of a thunderstorm will impact NE lower apn. Winds generally under 10kts with a tendency to turn to lake breezes Saturday afternoon (where most of the showers will develop). Marine Issued at 248 pm edt Fri jun 23 2017 gradient winds and waves not expected to be of any issue over the next several days. An overall west NW direction to the winds, with lake breeze tendencies and isolated to scattered showers and a few storms during the afternoons and early evenings.

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. |
