Overnight Forecast Discussion: April 6, 2012

Tonight's Hotspot: Northern Plains
a strong low pressure system will have ejected north to produce rain and snow in the area. Accumulating snows, up to 12 inches in the mountains, are possible. Under the warm sector, some spotty showers and storms may be able to gather enough strength and become somewhat stronger than 'average'. Warm air will flow north as a warm front begins to establish itself farther south.

Spotty rain showers mixed with snow and possibly a mix will be present in the Northwest tonight.

Far north Maine could have to deal with some icy conditions if a mixing shower comes along.

Forecast Discussion: April 6, 2012

Hotspot of the Day: Upper Rocky Mountains
A frontal boundary and nearby trough will be moving through the northern Rockies, producing snow. This wide swath of snow leads me to think that this will be an accumulating event, and it does apear that a general 8-12''+ is possible in the mountains, with 1-4 in the lowest elevations.

Central Plains
A low pressure system with attached trough will move into the Central Plains today. Showers and the occasional thunderstorm are expected, but nothing too severe at this point.

A large swath of rain and thunderstorms will move east today. No severe weather is expected.

Extreme Northwest
Some light rain and snow showers appear possible today in the extreme Northwest US.
