Area Forecast Discussion

228 PM EST Mon Dec 29 2025

.KEY MESSAGES...

  before subsiding.

- Lake effect snow will slowly diminish tonight, but areas of
  blowing snow will encumber travel.

- A pair of clipper bring a quick dose of snow Tuesday night and
  Wednesday night.

.DISCUSSION...
Issued at 224 PM EST Mon Dec 29 2025

A powerful low pressure system will continue track northeast. As it
does so, wind gusts will steadily decline. Lake effect snow showers
persist this evening, but are expected to diminish overnight. Very
cold much of this week with a couple of clippers Tuesday night and
Wednesday night.

A 980mb low located northeast of Lake Huron continues to produce 45
to  50 mph wind gusts as of this writing over our forecast area. The
synoptic burst of snow this morning, associated with a 65-70 knot
500-mb jet has cleared the area but a couple of stronger lake effect
bands continue to spill well inland reaching far northwest Ohio.
Thus, blowing snow and highly variable conditions are anticipated
for the evening commute, even for areas north of Fort Wayne. Steady
lake effect snow and windy conditions persist for those within the
Winter Storm Warning and Winter Weather Advisory. Visibility has
improved notably since the morning hours but conditions remain poor
allowing the winter headlines to continue. For the wind advisory, a
partial clearing was completed for some areas below 39 KTS.
Otherwise, frequent gusts of 39 kts or more continue, especially in
northeast IN and northwest Ohio.

Lake effect snow tapers off tonight as dry air entrainment occurs in
the low-levels and after midnight, inversion heights fall. The
trough axis now lifting northeast will pull the lake effect bands
steadily to the northwest, limiting the fetch as well. Wind gusts
tonight decreasing toward 25 mph will still be enough to cause
blowing and drifting snow which may impact the Tuesday morning
commute as well.

The next upper-level low dives in Tuesday night, followed by a
second, stronger 100kt jet at 500-mb Wednesday night. Thus, Wednesday
night's clipper could be stronger than the preceding one. Drying out
for the late-week period with temperatures moderating toward
freezing for the weekend.

.AVIATION /18Z TAFS THROUGH 18Z TUESDAY/...
Issued at 1131 AM EST Mon Dec 29 2025

LES and blowing snow the primary concern this afternoon into
tonight with varying visby's in and out of LES bands and gusty
west winds. Cigs will generally remain MVFR, with visby's mainly
ranging between LIFR and IFR at KSBN, and IFR to MVFR at KFWA.
Winds and LES coverage then diminish some tonight as drier
begins to filter in.

...Areas of snow and blowing snow continue this afternoon...

The combination of gusty west winds and lake effect snow showers
will continue to create difficult travel in spots this afternoon.
Visibilities will likely be reduced to a quarter of a mile in
heavier snow showers. Additional snow accumulations will
generally be an inch or less. However, the very gusty winds will
continue to allow for blowing and drifting. Motorists should
exercise caution and allow for extra time to reach their
destination.
