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.
Tropical system remains disorganized, but once in the Gulf of Mexico it may start to develop.
Heavy storms along the front today. System in the tropics is having problems but should get its act together soon.
Track of tropical system critical for development, but South Florida could be threatened first.
A new tropical system may be a threat to southern Florida late in the weekend and early next week.
The tropics will produce a storm that could impact the United States coast.
A cold front will be led by severe storms all the way to the Northeast this weekend. Tropics could produce a big storm.
