WHAT HAS CHANGED

Issued Cold Weather Advisory for tonight/Saturday morning.

Added some blowing snow to the forecast for tonight.

KEY MESSAGES

1) Clipper system today.

2) Cold temperatures tonight into the weekend.

3) Warming trend early next week.

DISCUSSION

KEY MESSAGE 1)

A clipper system will move southeast across our area today. Snow associated with it is currently dropping quickly southeast across Wisconsin and should move into our area toward daybreak. The snow will continue through the rest of the morning before quickly tapering off from the northwest heading into this afternoon. The snow will be banded in nature and within those bands, snow rates to around an inch an hour will not be out of the question, along with low visibilities. Since it will be a pretty quick hitter, it still looks like around 2 to 3 inches across about the northeast two thirds of our area, with the highest amounts in places that experience the better banding. Amounts across our southwest will be in the 1 to 2 inch range.

An arctic cold front will move south across the area late this afternoon and into this evening. Isolated to scattered snow showers will be possible into this evening along and behind the front. In addition, in the strong CAA, north to northwest winds will increase with gusts in the 25 to 35 mph likely heading into tonight. This will lead to areas of blowing snow.

KEY MESSAGE 2)

Temperatures will fall quickly tonight behind the arctic front with overnight lows in the single digits. This will combine with the gusty winds to produce wind chill readings in the 10-15 below range across our north and zero to 5 below in the south. Have issued a Cold Weather Advisory for tonight into Saturday morning for the northern half of our area.

KEY MESSAGE 3)

Temperatures will begin to moderate through the first part of next week. Highs by Tuesday will be in the 40s with some low 50s even possible along and south of the Ohio River.

AVIATION /06Z FRIDAY THROUGH TUESDAY/

A clipper system will move southeast across our area this morning. Snow will develop toward daybreak and become heavy at times from mid to late morning. Cigs and vsbys will quickly drop to IFR or below as the snow moves in. Snow will taper off fairly quickly through the afternoon hours, but IFR cigs will linger through the afternoon before lifting into MVFR this evening. A strong cold front will move through late this afternoon and evening, resulting in scattered snow showers. Wind will also increase behind the front with northerly winds gusting to around 30 knots through the end of the TAF period. Some localized LLWS will also be possible tonight.

OUTLOOK...No significant weather expected.
