So this is going to be new to the Merrimack valley weather page. If there could be a east coast storm. I will start posting maps as follows
5 days out + Map of what models are showing ( showing this with this post)
4 + days out Map of what models are showing and showing a forecast track precaution maps are possible
3 +days out. map of what models are showing, Precaution map/watches. What type of precipitation. snow map depending on confidence level
2+ forecast track, precatuion maps, road conditions, what type of precip, first snow maps and others.
within 2 days. forecast track, road conditions, type of precipitation and snow maps.
Map below shows, several weather models tracks for the storm for the 21st to 22nd. As you can see from the map. Most models are in agreement on track until about north caralina. Then it goes kind of a split. So alot is uncertain at this time. Of streangth, track, type of precip but looks possible at this time that some snow could fall some where.
Most weather models are here. Each has its on color.
