Thickening high clouds the result, with skies trending partly cloudy across much of the area. Mid and low level moisture will be much slower to arrive, likely taking to near sunrise to push into areas down near saginaw bay. Still appears any light shower activity will wait until after sunrise Tuesday to arrive (and once again, only for areas down near saginaw bay). Those increasing clouds will prevent temperatures from falling too much, this despite still very dry low levels. Inherited lows in the 30s to lower 40s still appears reasonable. Near term (tonight through Tuesday) issued at 345 pm edt Mon apr 23 2018 Chances for showers Tuesday... primary forecast concern... Rain shower timing and chances Tuesday. Increasing mid high clouds tonight should keep it on the mild side with lows in the middle 30s to lower 40s expected. The combination of low pressure moving by to our south and a surface cold front approaching from the northwest will increase shower chances Tuesday. Lots of dry air to overcome at lower levels so northern zones will have a hard time moistening up enough to produce rain showers. Farther south across much of northern lower (perhaps minus the tip of the mitt) moisture is deeper so there will likely be at least a few showers around in the afternoon. Highs Tuesday ranging from the upper 50s to lower 60s. Short term (Tuesday night through Thursday) issued at 345 pm edt Mon apr 23 2018 Midweek (mostly) rain threat with drier milder weather Thursday... high impact weather potential: minimal. Pattern synopsis forecast: current split flow pattern across the conus with a southern branch upper low spinning its way across the tennessee valley... With the great lakes stuck in between this low and stronger northern branch flow across southern portions of saskatchewan manitoba and northern ontario. Decent looking northern branch disturbance emerging from the northern rockies and into the high plains this afternoon... With another northern branch short wave trough farther upstream over northern saskatchewan. It is this latter piece of energy that will swing southeast and across michigan Tuesday night Wednesday... Followed by a stronger disturbance digging southeast and likely impacting michigan in the Thursday night Friday time period. Surface cold front stretched out across northwest ontario will lie across michigan Tuesday Tuesday night... Surface high pressure builds |
southeast behind the front Wednesday which will allow for northerly boundary layer flow to push cooler air into northern michigan. This will likely be reinforced by another cold front attendant to following short wave trough Friday. Primary forecast concerns: deep layer moisture will be across the forecast area associated with two systems Tuesday night... Some getting pulled northward from southern branch upper low... And some from northern saskatchewan short wave trough. Plan on lingering moisture and precipitation chances longer into Wednesday across far eastern upper northeast lower than depicted by the quicker GFS and especially nam-wrf. Anticipating drying Wednesday evening with more widespread sunshine for Thursday. After our recent spell of seasonably mild temperatures... Highs likely to return to the 40s for Wednesday... Then back into the 50s (and probably some lower 60s) for Thursday afternoon. Long term (Thursday night through Monday) issued at 345 pm edt Mon apr 23 2018 a relatively sharp cold front will drop down from canada to kick off the start of the extended period... With passage in the Thursday night through Friday time frame. The precip will likely be all liquid... But this front is looking like it may drag down enough cold air that a few snowflakes shouldn't be ruled out... Particularly should the precip line up with the diurnal cycle and occur at night. Some straggling moisture may linger into Saturday... But the drying trend should commence and last into Monday. A temporary dip to cooler than normal readings can be expected at the start of the period... But temperatures will moderate through the second half of the weekend, back to seasonal by Monday. Aviation (for the 00z tafs through 00z Tuesday evening) issued at 711 pm edt Mon apr 23 2018 some changes expected as area of deeper moisture gradually rotates north later tonight into Tuesday.VFR conditions under a slowly lowering and increasing cloud deck tonight, with the potential for MVFR CIGS arriving Tuesday, especially at kapn. Light rain showers also possible, but will exclude these from this forecast at this time. Light winds through the duration. Marine Issued at 345 pm edt Mon apr 23 2018 as low pressure lifts thru the ohio valley Tuesday night... Winds will increase and likely reach SCA criteria Tuesday night across the western great lakes between this low and high pressure over minnesota. Apx watches warnings advisories Mi... None. Lh...

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. |
