March 13, 2026 11:36 am

High pressure will bring near-record heat to inland areas today while the coast begins to cool. Onshore flow on Saturday will bring cooling to below record levels. For next week, high pressure will strengthen with widespread record heat for all but possibly the immediate coast with monthly records for March likely to be set at many locations for the valleys, mountains, and deserts. There will be widespread moderate to locally major heat risk for inland areas next week peaking around Thursday and Friday.

Intense clipper-like system bringing heavy snow across the Upper Midwest into the Upper Great Lakes early today along with widespread blustery conditions. Active Atmospheric River pattern bringing heavy lower elevation/coastal rain and high elevation snow to the Pacific Northwest and northern Rockies. A winter storm will gradually develop across the northern High Plains today into Saturday before expanding and intensifying across the northern Plains later on Saturday, reaching into the upper Midwest Sunday morning. An anomalously early heatwave will begin to build over the western U.S. heading into the weekend. Critical Risk of fire weather for the central/southern High Plains.
