Area Forecast Discussion National Weather Service Gaylord MI 619 PM EST Tue Jan 28 2020

NEAR TERM. (Through Tonight) Issued at 324 PM EST Tue Jan 28 2020

. Nuisance light lake effect precipitation continues .

High Impact Weather Potential: Minimal. Some minor icing in spots due to freezing drizzle.

Pattern Synopsis/Forecast: Northern stream short-wave trough/vorticity center continues to slide down into the central lakes region this afternoon, downstream from low amplitude short- wave ridging working into the western Great Lakes. Typical lake aggregate surface troughing remains fixed from the U.P. down through northern Lake Huron with light low level NW flow across most of the area. Just enough over water instability continues to touch off some very light lake induced precipitation, largely across NW Lower Michigan, which has and continues to be a mix of light snow showers and light freezing drizzle. Meanwhile, surface high pressure/subsidence and drier air is across western Ontario and will muscle their way into northern Michigan as we go through tonight.

Primary Forecast Concerns: Nuisance light lake induced snow showers and freezing drizzle through tonight.

Short-wave trough will continue to slowly slide southeastward out of the region tonight, replaced with short-wave ridging/surface high pressure and some drier air building into the northern lakes. Along with eventual veering low level flow, current coverage of light lake induced precip should dwindle, although I suspect areas from Grand Traverse Bay south to Manistee as well as parts of NE Lower Michigan will probably continue to see some nuisance light snow showers/freezing drizzle. Areas further north into eastern Upper Michigan could see some clearing skies take shape with developing NE downsloping flow out of Canada.

SHORT TERM. (Wednesday through Friday) Issued at 324 PM EST Tue Jan 28 2020

High Impact Weather Potential: None

. Mostly quiet weather heading into the weekend .

Pattern synopsis:

Upper-level troughing will continue to move across the southeastern US through Wednesday before elongated ridging takes its place. A more amplified trough will dig from the Rocky Mountain west into Texas/Mexico through mid-week as well. At the surface, a cyclone associated with the southeastern US troughing will scrape along the Gulf coast into Florida Wednesday night before exiting into the Atlantic. Surface high pressure centered over James Bay will continue to build down into the CONUS, encompassing the Great Lakes through the short term.

Forecast/Details:

Surface high pressure is expected to mute precip on Wednesday and Thursday. Some near-surface moisture exists that could potentially support light snow/freezing drizzle, but lack of appreciable forcing in the low and mid-levels brings confidence against precipitation on both days. Weak winds are expected through the period as well. High temperatures will reach near 30 across northern lower while eastern upper will likely see mid 20s. Upper 20s highs are expected on Thursday. Chilly lows are expected overnight both days, dipping down into the teens and possibly single digits for some across the area.

LONG TERM. (Friday night through Tuesday) Issued at 324 PM EST Tue Jan 28 2020

High Impact Weather Potential: Minimal . Monitoring early week.

Surface high pressure will begin to move out of the eastern CONUS heading into the weekend. The next chance for precip appears to be on Friday with the arrival of a potential shortwave the could bring support aloft. Precip chances could continue through the weekend with a possible system passing to our north near Hudson Bay. Guidance hints towards an organized system developing and potentially impacting the Great Lakes early next week, but there is still plenty of time between now and then and details will become more clear as next week approaches. High temperatures look to warm some heading through the weekend, possibly reaching into the mid 30s for many on Saturday and Sunday. Warmer than normal temperatures could continue into early next week before the overall pattern changes.

AVIATION. (For the 00Z TAFS through 00Z Wednesday evening) Issued at 618 PM EST Tue Jan 28 2020

Lots of MVFR cloud cover remains draped across northern Michigan along with light nuisance lake induced snow showers/light freezing drizzle.

Lake induced precipitation will tend to diminish tonight as surface high pressure builds into the region and light low level flow veers easterly, eventually southeasterly on Wednesday. Cloud cover may also thin out a bit, particularly well downwind of the lakes. But anticipate overall MVFR conditions to persist through the taf period.

MARINE. Issued at 324 PM EST Tue Jan 28 2020

Light winds/waves will continue on the lakes through the balance of the week. Some light/nuisance lake effect precipitation will be found on the lakes tonight into Wednesday. Otherwise, no high impact weather is anticipated.

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.
