3PM Snow Update

Sorry this update is a bit later than I promised. I ran into some difficulties with making the snow map.

The lake effect has been pretty disorganized through the day as winds haven't really aligned themselves well yet. The models showed this happening relatively well. This disorganization should continue until about sunset, when things really start to get going. I am expecting multiple bands of lake effect to form, with probably two main bands. They will move around a bit overnight, so plenty of areas should see some high snow totals. Here is what I am thinking for amounts by 9AM tomorrow morning:

As with any lake effect event, not every area within each contour will get that amount of snow and the variance from one spot to another can be very large. So, that snow map shows the most likely amounts that are to occur in each area.

Tomorrow, the lake effect should calm down as the day gets into the afternoon. Additional accumulations tomorrow will likely be anywhere from 1-4" in the white and light blue areas, to 3-7" in the darker blue.
