Winter Storm Denise Snowfall TotalsJanuary 30th, 2013 at 9:06 pm by Patrick Powell under Weather
This post is to give everyone an update on the snow reports around northeast Wisconsin from Winter Storm Denise and to compare the forecast with what actually occurred. Overall I feel that we did a good job of forecasting but there were areas that we could have done better. The first graphic is my forecast from yesterday at 5 PM. This was the first snowfall forecast that we made at FOX 11 for the storm. I think that we had the right idea, but I was reluctant to go any higher with amounts. With a transitional deformation type snow event that included a change from rain to sleet to snow and initially had a wet ground I felt that a little of the snow would melt on contact and the initial wet nature would allow some compacting.
As the snow intensity increased and the banding developed by late morning I updated the forecast to the second graphic, with the 8-11 inch band over the Fox Valley. With falling temperatures, not only did we get better snowflakes but also better snow ratios. For a 4 hour period this afternoon we pick up snow at 1 inch per hour! Pretty impressive snowfall rates. By lunchtime today we had a great idea of what was happening, but we were also half way through the snowfall. The banding with this storm was a little more intense and lasted a little longer than I thought it would.
Since posting this story we have had a few snow reports that need to be updated.
They are Sturgeon Bay 8.0″, Fond du Lac 6.0″, Clintonville 7.5″, Gillett 8.0″, New London 8.0″.
