All sorts happening with the weather across the United States at the moment with the main feature being a change across the Great Plains from the record warmth of recent days to much colder conditions.
A low pressure system moving across the northeast of the United States will bring outbreaks of snow across Pennsylvania and Maine. This feature looks set to deepen as it moves out over the Atlantic, bringing heavy snow to Maine, New Hampshire and eastern Massachusetts with up to 6 inches possible widely, and perhaps more over parts of Maine.
After the very high temperatures, in the 70's and low 80's over the central and southern Plains earlier this week, it has turned colder as high pressure moved down from Canada following the passing of a cold front. This is bringing temperatures back closer to normal along with mainly settled conditions, although it will be windy at times.
Finally we are expecting some very wet conditions across the Southwest and southern Plains during the next few days with a weather system bringing plenty of rain with it, heaviest and most persistent over Arizona and New Mexico. Accumulating snow is expected for the higher parts of Utah, Colorado, and New Mexico. As we go through the weekend snow is expected over the Midwest states with rain to the south.
