Low Pressure Developing Over Western US

A large area of low pressure will form and intensify over the western US today and tonight. It will kick up the winds across a broad area, as seen in the US watch/warning/advisory map below -- with all the fire weather watches in place from Arizona to Montana.

As that low pressure begins to move east on Thursday, it will have the potential to kick up quite a fairly large severe weather outbreak in the middle of the country.

Meanwhile it is chilly around the Great Lakes as an area of low pressure pulls cold air south out of Canada.
