NEAR TERM. (Through Tonight) Issued at 403 PM EST Tue Dec 10 2019

. Lake Effect Changes .

High Impact Weather Potential . Moderate to potentially heavy snow is possible tonight in the Tip of the Mitt and in W. Chippewa

Pattern Synopsis/Forecast . 1000-850 mb winds are backing to the west this afternoon as the sfc high builds into the Upper Great Lakes and Mid-Mississippi Valley. With the transition, the bands initially had an uptick, but since then they have broken up into more cellular structure along the bands. Looking at the satellite images and the upstream radars, the models seem to have a decent handle on these bands, and the expectation will be that the winds will continue to back to the wsw by the evening and remain that way through about 12z/Wed. Moisture in the 850-700 mb layer will diminish through the night, however, so the thought is that there will be some moderate snow bands that will reestablish along the wind streams, but will begin to diminish as the drier air moves into the region.

Primary Forecast Concerns . As with any lake effect situation, a lot of the concerns focus on the winds to maintain a consistent wind direction and fetch over the open lake. In this case, Emmet and cheboygan counties look to be probably end up with an 18 hour total (18z/Tue-12z/Wed) of 5-8 inches, and 3-5 near Whitefish Pt. Of course, the issue is, can we get warning amounts (8"+)? It is possible, and based on this morning's performance, where it looks like we got about a foot in NE Kalkaska county, It is not inconceivable.

SHORT TERM. (Wednesday through Friday) Issued at 403 PM EST Tue Dec 10 2019

High Impact Weather: Additional accumulating lake effect snow Wednesday morning then widespread accumulating snow Thursday.

Primary Forecast Concerns: Snow amounts Thursday.

Southwest winds will continue to target Emmett and Cheboygan counties Wednesday morning with additional accumulating lake effect snow showers (1 to 3 inches) so the winter weather advisory will go through noon. Winds then veer into the west northwest in the afternoon shifting the lake effect farther south possibly accumulating an inch or two. Lake effect should be light Wednesday night with weak high pressure in control. An Alberta Clipper will increase warm air advection/isentropic ascent and combine with marginal lake enhancement possibly bringing a sneaky few or possibly even several inches of snow to mainly northern areas (targeting eastern upper and the Tip of the Mitt) during the day Thursday. Perhaps some lingering snow Thursday evening then quieter weather moves in overnight Thursday into much of Friday. Temperatures will be very cold Wednesday with temperatures moderating toward normal Thursday and a few degrees above normal Friday.

LONG TERM. (Friday night through Tuesday) Issued at 403 PM EST Tue Dec 10 2019

High Impact Weather: Mixed precipitation possible Saturday.

Milder air looks like it will hang on through much of Saturday with more cold air dumping into the region Saturday night into early next week. Extended models are then trying to drop a brutally cold chuck of air into the region just beyond the scope of this forecast (middle and end of next week). The combination of a weak weather system moving through Saturday and short wave energy moving through the flow will bring decent chances for light snow or flurries Friday night through Sunday. The snow may even be mixed with a little rain Saturday. Fairly quiet weather is expected early next week, although we will have to watch a weather system which is shown to move by to our south.

AVIATION. (For the 18Z TAFS through 18Z Wednesday afternoon) Issued at 1245 PM EST Tue Dec 10 2019

Lake effect snow bands continue this afternoon into Wednesday as the low pressure continues to retreat east, and the cold air with associated with the sfc high pressure continues to stream over the relatively warm Great Lakes. Winds in the layer from the sfc to about 5000 feet are beginning to the WNW and will continue to back to the WSW by this evening. The change in direction will push the snow bands from the TVC and mbL toward PLN. While light snow is still possible at mbL and TVC, the MVFR/IFR category vsbys and CIGS will be mainly limited to PLN where the the bands are expected to reestablish themselves.

APN will see a brief lowering as the snow bands and clouds move through the taf site while the bands shift with the wind direction. For the rest of the TAF in APN, the cigs and vsbys will remain VFR/MVFR.

MARINE. Issued at 403 PM EST Tue Dec 10 2019

Tonight through Thursday . Looking through the winds on the vertical profiles for tonight, the winds look to be solidly small craft criteria with gusts to 30 knots. As the sfc high, looks to move south of Michigan, tightening up the pressure gradient as the winds begin to ramp up. Wednesday, the winds on Lake Michigan will begins to diminish as high pressure builds into the state, with winds on Lake Huron continue until Wednesday night, when all of the lakes are below small craft. Thursday, another sfc low moves into the Upper Mississippi Valley, and the high has moved east of the Upper Great Lakes, which will produce stronger return flow winds (south) by the afternoon, mainly on Lake Michigan. Small craft will be possible by Thursday afternoon on Lakes Michigan and Huron.

APX WATCHES/WARNINGS/ADVISORIES. MI . WINTER WEATHER ADVISORY until noon EST Wednesday for MIZ016-017. WINTER WEATHER ADVISORY until midnight EST tonight for MIZ086. LH .
