Some snow tomorrow. Whats next?
Expect some very cold temperatures tomorrow morning with lows getting into the teens and possibly even single digits in spots. It'll warm up above freezing in the afternoon.
Snow showers will move in during the evening. Expect snow showers and flurries to continue into the night. I don't expect any big accumulations. In 2 inch amounts in the 1-2 range will be reserved to the highest elevations. Areas that are under >1 inch can still get a coating on grassy surfaces but nothing more.
Wednesday will be cold, dry and breezy with temperatures staying the 20s all day.
Thursday will be a little warmer with highs into the 30s. Don't rule out a few snow showers or flurries especially in the afternoon.
Friday will be even warmer with highs in the upper 30s and low 40s.
Saturday and Sunday we need to watch for our next storm threat. I have outlined three possible scenarios.
Scenario #1 begins Friday as two separate low pressure systems form in the southeast. The high pressure to the north is strong enough to push the eastern one to the coast but too weak to send the western low pressure east. The eastern low pressure would soon turn into a nor'easter. However, the western low pressure will bring in warm air.
If this scenario were to happen we would likely be left with a mostly rain event with a period of wet snow in northwestern portions of the coverage area.
Scenario #2 is a bit different than scenario #1. First off, the low pressure the two low pressure systems start as one low pressure located in Texas or Louisiana. The low pressure soon splits with the eastern one immediately going to the coast. The other difference is that the high pressure to the north is stronger preventing the western low pressure from heading into the Great Lakes. Instead, the western low pressure heads east and is eventually absorbed by the coastal low pressure. The combination of the energy from the western low pressure and unusually warm ocean temperatures will allow the storm to bomb out and become very strong.
If this scenario were to verify the coverage area would be left with a significant snowstorm. In addition to that, the coast would expect strong winds and some coastal erosion.
Scenario #3 start similarly to scenario #1, the biggest difference between scenario #3 and the other two scenarios is that the high pressure to the north is significantly weaker. This would in turn prevent either low pressure from reaching the ocean.
In this scenario the coverage area would be left with soaking rain similar to the storm on Sunday.
So basically what we need to do is determine how strong the high pressure to the north will be and we can determine what track the low pressures take. The problem is that how strong the high pressure is, is directly related to the track tomorrows Alberta Clipper takes, which is uncertain. For now all we have to do is wait and watch what the models put out and examine the current pattern.
