Snow Event and Snowfall Amounts
Update...2/1/14 - 12 Noon
Radar and surface observations indicate heaviest precipitation as of 12 noon aligning up from near Jackson...east northeast across Detroit's west and northwest suburbs into the northeast suburbs. Therefore; will drop the expected 4-8" snowfall band just slightly south of the Livingston/Washtenaw... Oakland/Wayne...Macomb/Wayne borders. These areas will see snow...sleet and possibly a bit of rain mixed in this afternoon before back to snow. The remainder of the region looks ok as is...
With the calendar page barely turned and another storm is taking aim on the southern Great Lakes. While this storm is not a major one as far as intensity; it will have a good moisture supply to dump snow and mixed precipitation over Southeast Lower Michigan.
While some patchy light snow or snow showers may fall this evening; the heavier, continuous wet snow will overspread Southeast Lower Michigan during the early morning hours of Saturday. It will become mixed with a period of sleet and freezing rain before changing to rain over extreme Southeast Lower Michigan. Before the change; look for mainly 2" - 3" of snow over extreme Southeast Lower Michigan (Ann Arbor to Metro Detroit and points south) with pockets of 4" before the snow becomes mixed, or changes to rain. Further north from Detroit's northern suburbs up across Flint, Saginaw and the Thumb Region, a heavy wet snow of 4" - 8" is likely to fall on Saturday.
After this weak system slides through; a weak high pressure will dominate into Tuesday. A more impressive low pressure and high pressure are slated to affect the region from mid week into next weekend. Early indication are a classic Ohio Valley low will deepen and gain strength and head northeast toward Ohio late Tuesday into Wednesday. This system will be mainly a snow system and how close she comes to Southeast Lower Michigan will determined how much snow falls over our region. Then; late in the week, the large cold high pressure will push into the Midwest.
More on these systems later...
