1. The AO hit its lowest point over the weekend, so it's uphill in regards to temperatures. It will be a gradual uphill battle to warmth in the eastern part of the country, not a dramatic turnaround. I think it will remain on the cool side through April relative to normal.
2. I posted the HRRR model snowfall because it shows what I am thinking in regards to snowfall, although it might be on the high side in amounts. New Jersey, Delaware, southeastern Pennsylvania will see the heaviest snow today although there will be heavy snow showers across the Ohio Valley into western and central Pennsylvania.
3. Once the storm is done tonight, it will be quiet for a few days until the weekend when the GFS hints at big thunderstorms developing in the midsection of the country. We will see a return of warmth and humidity into the Plains which should be the fuel for storms to develop.
The snowstorm will dump heavy snow today into Tuesday, but the warmth is on the way for later this week.
It's going to be a stormy period across the country, but the models seem to differ on the outcome.
The storm that is coming into the Plains will produce a wide range of weather including snow, ice and flooding rains.
The holiday time will be stormy in the Plains and Front Range of the Rockies. Travel will be impacted by the weather.
A swath of moderate to heavy snow to move from the Midwest through the Great Lakes.
