So it looks like we will start off December with a decent snowstorm for the central and especially eastern areas of NYS.
Looks like 1-3" across WNY, 3-6" for Rochester, 6-12" for Syracuse.
Following this storm there is an interesting period on Weds where a lake enhanced setup may affect Buffalo and give them a few inches.
On an initial SW flow, lake effect snow is expected to begin near
Buffalo/Watertown Tuesday night. It likely will not be until early
Wednesday that lake parameters maximize...with Lake Induced EQL
rising to near 7-9K feet, and moisture increasing in a lowering snow
dentritic growth zone that the bands of snow will become moderate.
By this time, with the upper level shortwave crossing our region,
expect the bands of snow to be now east of the Lakes, across the
Southtowns/Boston Hills and the Tug Hill region. Here on Wednesday
we will increase PoPs to likely for lake effect snow.
Looking further out....
A very up and down pattern upcoming. Lots of warm ups and cool downs. No real sign of any arctic air in the forseeable future. We get some pacific help with a +PNA but we go positive for the NAO and AO with the PV on the other side of the globe. The models have been highly volatile though, so this doesn't mean much. I think weeks 2 we get a decent torch according to the CPC. Hopefully the pattern changes but it looks like we're heading into a warm MJO cycle.
