WHAT HAS CHANGED
Introduced lake effect snow showers for Tuesday and Wednesday, but snow accumulations will be light.
KEY MESSAGES
1) Arctic air mass remains in place through the weekend.
2) A little warmer this week with some lake effect showers Tuesday through Wednesday.
DISCUSSION
KEY MESSAGE 1...
Tonight should see less cloud cover than last night, so temperatures will likely dip below zero across a large portion of the region. Cold weather advisory is in effect through tomorrow morning. Highs tomorrow will only climb into the teens or slightly lower. After tomorrow, ridging will build in to start the work week and this will help increase temperatures across the region. High temperatures on Monday will feel like a relief, even though it will only get into the 20s.
Key Message #2...
A shortwave trough drops south out Ontario, Canada on Tuesday. This will increase snow shower chances across Central NY, especially when wind slow switches from SW to WNW Tuesday night and Wednesday. Expect to see some more lake effect snow showers at least through the day on Wednesday and possibly extending longer through the middle of the week. Towards the end of the week, there is potential for a clipper system to bring more widespread light snow to the region, but will hold off adding this to our key message until confidence increases in the forecast being this is Day 6/7.
AVIATION /00Z SUNDAY THROUGH THURSDAY/
Some MVFR restrictions early this evening from ceilings and isolated snow showers. Ceilings should lower slightly overnight at all TAF sites, perhaps scattering out at KAVP. A few additional light snow showers and flurries are possible Sunday coming off of the Finger Lakes as well. A few wind gusts could reach 20 knots in the afternoon.
Outlook...
Sunday Night...Lingering MVFR to localize IFR CIGs continue at most taf sites in the cold N-NW flow
Monday Through Thursday..Mainly VFR; low chance (25% or less) for snow showers and restrictions at times due to occasional lake effect.
