Winter Storm Update: Part II

The snow is starting to move in, but a small change to the forecast could really affect our snow totals heading into Friday morning.

Precision Doppler at 9:29pm
The overall timing of the forecast and the hazards with this storm haven't changed. We're still talking heavy bursts of snow late this evening through the early morning hours combined with wind gusts of 30mph to create lowered visibilities and blowing and drifting snow. Roads will be messy Friday morning, although winds and snow will calm significantly heading into the afternoon.

RPM Model: Accumulated Snow Through Friday Night
Here's the change... dry air is starting to get wrapped up into the storm system. This means accumulating snow may end earlier than expected, especially to our south. In fact, our latest in-house models are picking up on that drier air and dropping snow totals along the I-88 corridor.

Official First Warn Snow Forecast
We won't change the overall snow forecast. We're still calling for 3-6" by Friday morning... maybe a little more to our west. But at this point, we might be closer to 3" of snow instead of 6" to finish the work week. -BA
