This is the end of the meteorological fall today. We ended the month of November with below-normal rainfall with 1.99 inches and we had 8 inches of snow. Rainfall for the fall season was above normal with 11.75 inches.
We will see partly sunny skies today with brisk winds and temperatures in the 40s. Tonight we start a more active weather pattern with a mixed bag of rain and snow. This may persist through the weekend and at this time most of the wet snow will fall north of I96 with mainly rain south.
Bittersweet down the road from me is open with four slopes operating.
Weather History for SW Michigan
1958: November ends on a frigid note with lows in the single numbers and highs only in the lower 20s. From 6 to 10 inches of lake effect, snow piles up near Lake Michigan.
1976: One of the coldest November on record ends with a blast of arctic air that drops low temperatures near zero and keeps highs only in the teens. Big Rapids falls to one degree below zero and Grand Haven measures three inches of lake-effect snow.
Weather History for SE Michgan
On November 30th, 2011, a low-pressure system tracked northeast into the Eastern Great Lakes allowing rain to change to snow, with total accumulations of 4 to 8 inches occurring over the Tri-Cities region, Shiawassee, and Livingston Counties. Elsewhere, generally, 1 to 4 inches of wet snow fell. Some of the higher snowfall accumulations that were reported included Auburn and Perry with 8 inches, Midland with 6.6 inches, Howell with 6.2 inches, and Bridgeport with 6.1 inches.
On November 30, 2008, a snowstorm hit Southeast Michigan and continued into December 1. The storm mainly affected the Flint, Saginaw, and Thumb regions. The heavy, wet snow piled to 5 to 8 inches, downed trees and power lines, and left about 25,000 customers without power. Some of the higher snowfall totals included 8.6 inches in Marlette, 7.0 inches near Chesaning, and 6.0 inches in Perry.
On November 30, 1999, cold air poured into the Great Lakes, as high pressure moved southeast from central Canada, producing several bands of lake effect snow over Lake Huron. One of the bands to move onto the eastern shore of Michigan Thumb. Measurable snow fell from Huron City, south to Marine City. Heavy snow fell from Port Sanilac to Port Huron, 7 inches accumulated during the morning.
On November 30, 1940, a snowstorm left Saginaw with 11.9 inches of snow, Flint with 7.8 inches of snow, and Detroit with 3.8 inches of snow.
U.S.A and Global Events for November 30th:
November 30, 1925:
An extremely rare late November hurricane began to affect the west coast of Florida as it strengthened during the day. The storm made landfall very early on December 1st south of Tampa Bay, weakened to a tropical storm as it crossed central Florida, and exited around St. Augustine. The storm regained Hurricane strength off Jacksonville late on the 1st. Heavy rain continued over northeast Florida on the 2nd. Gale force winds were reported from the Keys to Jacksonville and over 50 people lost their lives, mostly on ships at sea. Damage along the coast south of Jacksonville was heavy and excessive rain and wind seriously damaged citrus and truck crops.
Few icy spots may be possible this morning as patchy fog moves through areas mainly along and north of I-96. Road temps are currently in the upper 20s with air temps right around freezing. An SPS may be warranted to highlight potential hazardous driving conditions for the morning commute due to black ice. Zonal flow dominates the regime over the eastern CONUS today supporting decent warm air advection with 850mb temps climbing towards +3C to +4C. This will bring high temperatures back into the 40s today. In addition to warmer temps, winds will be breezy as a 45- 50 knot LLJ sets up overhead. Inversion heights up towards 1-2kft will support gusts to 25-35mph mixing down to the surface this afternoon. Bigger area of focus for the forecast will be on a system that will move through the area late tonight through Friday. In this event, a shortwave will track northeasterly from the Southern Plains into the Ohio Valley/southern Michigan. This system still looks likely to produce a mix of rain and snow with the rain/snow mix arriving near I-94 after midnight, then towards the I-96 corridor after 7am Friday producing mainly snow. Model guidance continues to highlight the higher swath of 1-3 inches of snow occuring within the I-96 to M-46 corridor, but with many varying thermodynamic parts in play it`s possible this band of snow could be much more narrow. Possible mesoscale banding will support higher snow rates at times Friday morning which may allow some accumulation on area roads. Hazardous travel will be possible for the Friday morning commute. The front remains nearly stationary over the MI/IN/OH state line area for Friday night with a second upper shortwave sliding through aloft. Weak persistent isentropic upglide will continue much of Friday night, so we expect precipitation to continue Friday night with a rain/snow mix north of I-96 and rain off to the south. There is potential for a wet 1-2 inch snow fall over portions of the central and northern CWA. Location of the front and exactly what the low level thermal profile are like will dictate location and amounts. At this point though it looks like north of I-96 and on the order of around an inch potentially. Precipitation tapers off on Saturday, but does not completely end as we move through the weekend given an upper trough and shortwaves moving through the region. We have higher pops into Sunday as our model blend is likely leaning a bit on the GFS which has a surface low moving directly through the CWA. The ECMWF is further east with the low development. Rain and snow are in the forecast over the weekend with critical temperatures near thresholds for both ptypes. As we head through the early to middle portion of next week, conditions become a bit quieter as northwest flow trends towards ridging. One final low may move through the region in the Tuesday time frame though and we have 20-40 pct pops in the forecast for both rain and snow. Temperatures through the period will be near normals and also conducive for a mixture of precipitation types (Rain/Snow).
