Area Forecast Discussion National Weather Service Detroit/Pontiac MI 537 AM EST Sun Jan 26 2020

AVIATION.

Fairly extensive IFR/low MVFR stratus canopy extends from the Appalachians to the Northwest Territories, encompassing most of Canada east of the Rockies and the entire Great Lakes region. Persistence will therefore be suitable going forward with low cigs expected for the remainder of the forecast period. Flurries or drizzle will be light/sporadic in coverage through the early portion of the day before -rasn coverage expands during late afternoon in response to a passing upper wave. Rasn eventually changes to all snow with nocturnal cooling and within any heavier showers. Little/no accumulation due to transient nature and poor organization. Wind then veers to NW overnight. Guidance generally suggests slightly deeper cold air within NW flow will aid improved vsbys while cigs remain solidly IFR.

DTW THRESHOLD PROBABILITIES .

* High for cigs aob 5kft.

* High for snow before 15z. Medium for rasn 15-22z. High for snow after 22z.

PREV DISCUSSION. Issued at 309 AM EST Sun Jan 26 2020

DISCUSSION .

Occluded low pressure system will slowly vacate the region over the next 24 hours. Substantial component of low level moisture immersed within the trailing deep mid level cyclonic flow will continue to govern conditions through the daylight period. This ensures extensive low stratus holds firm, while offering the potential for intermittent light precipitation development given the inherent upward vertical motion noted within this pattern. Early day precipitation type perhaps met by some question on whether ice exists in the column, as the top of moist layer flirts near -10C. This will simply translate into some combination of drizzle and flurries for the morning period. Moisture depth will increase with time into the afternoon, as shortwave energy now fixated north of lake Huron pivots southward through the back edge of the exiting mean height fall gradient. This likely maintains a pervasive field of flurries or non-accumulating brief snow showers. Brief uptick in forcing tied to the inbound shortwave may offer a more focused window for snow shower development during the late afternoon and evening hours. Absent of any meaningful low level thermal advection, temperatures will hold solidly within the 33 to 35 degree range during this time. Thus, any accumulation - particularly after sunset - will remain minor.

Pattern characterized by a general northwest flow through the mid- week period. Conditions Monday will remain defined by a resident thermal profile that leans several degrees above average and a relentless coverage of lower stratus. This pattern may offer a weak shortwave of northwest Canadian origin for the Tuesday period - perhaps yielding a brief window for flurries or inconsequential snow showers, but evidence insufficient to provide an introductory mention at this stage. Minor cold air advection edges temperatures down a touch for the mid-week period, but hardly noteworthy by late January standards. Brief period of low to mid level ridging maintains this stretch of benign weather conditions through Thursday.

MARINE .

Winds will increase today on the backside of this system as it moves into Canada, but gusts will stay below 30kts. High pressure over the Canadian Plains will slowly overspread the region Monday and remain for the majority of next work week.

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.
