Let's begin with an overview. In the West, winter storm conditions are expected today and tonight.
- The green in Northern California and far southwest Oregon are flood watches.
- Pinks are winter storm warnings
- Browns are high wind watches/warnings
- Purples are winter weather advisories (a lesser condition than a watch or warning)
- And, the deep bluish green in the Great Plains and Midwest is a winter storm watch
If you are traveling by car in the Midwest or Great Plains on Sunday, you may want to reconsider your plans. Not only will there be heavy snow, there will be high winds that will cause drifting and extremely hazardous road conditions.
The maps below are for planning purposes. The snow amounts, at this point, are approximations.
Below is the forecast radar for 4am Sunday. Blue is snow and darker blue equals heavier rates of snowfall. The storm will begin to intensify rapidly at this point.
This is the forecast radar for 1pm Sunday. Winds will be gusting to 30-35 mph from eastern Kansas to the Mississippi River.
Finally, the map below is the forecast accumulations as of 7pm Sunday. Some areas will have nearly a foot with considerable drifting.
While there is uncertainty as to the amounts and exact locations, I am highly confident a major storm will occur and I am confident as to the timing. I recommend considering altering your plans if you are planning to travel though this area Sunday or Sunday night.
