- Primary low is beginning to fill and has been slowly over the last few hours as it makes its adjustment to a secondary to the east. Where this low forms will be key to changeover times and how much wintry weather falls.
- Pressure falls have really took aim towards NC/VA the last few hours with this latest one really showing the drop of 5mb over last 2hrs. This is telling us that the secondary might pop well to the east of the forecasted position of this low.
- This would keep the cold air in longer and the NE winds in longer.
-Also the winds were supposed to turn easterly at 1400z and we are now approaching 18z with a strong NE wind still intact. However signs of easterly winds are showing up in AC.
We are going to be watching this closely the next few hours!
snow lover--i think the reason even you are changing to rain is the coastal low is talking over which means the wind direction is turining more northeasterly to easterly. If we hadn't had near record warmth in the last cpl months, and if the water temps were cooler, and if we weren't still in December (warmer water temps) then you would be getting buried in snow. The problem is its still december and with water temps above normal---Even a coastal brings rain well inn from the coast due to warm water temps
Now the good news--Saturday's storm should be ideal for snow because it's way for south..its a good setup as Rob says. Although the qpf may be lower due it being so far south, the precip type will be all snow due to a northerly to northwesterly wind... Again, until the water temps cool down we DO NOT
Snow has changed to Sleet/Rain here in Northern Lancaster County. Local Mets. nailed it so far. I keep hearing that the storm is farther east than models showed it changed to rain/sleet at projected time.............how is that? Shouldn't there be more cold air associated with the storm now?
