The Pacific Northwest will see the heaviest precipitation across the country as an atmospheric river and cold front are presently moving ashore. The coastal zones may see rainfall accumulations in the 2-3 inch range and as much as 3-5 inches in the Cascades and Olympic mountain ranges, prompting an isolated risk of flash flooding and perhaps some river flooding, with the Skokomish most at risk. Additionally, gusty winds and high waves are hazards with this storm system. Elevation snow in the Cascades is also likely Saturday. A reinforcing disturbance will bring additional rain showers into Sunday and eventually push a cold front through the Northwest. An intense cyclone is expected to move northeast, away from New England. In its wake will be modest lake effect precipitation on Saturday, and the cold advection will keep temperatures below average this weekend into Monday east of the Mississippi River due to the persistence of upper level troughing. An approaching front bringing precipitation back into the picture for the Great Lakes late Sunday into Monday. To the south, a weak cyclone/cold front looks to bring chances for rain across the Midwest and Texas Gulf Coast today (with some storms near the Texas coast strong to perhaps severe), portions of the Tennessee/Ohio Valleys late Saturday into Sunday, and to portions of the Carolinas and Mid-Atlantic coast late Sunday into Monday. Central and southern portions of the Intermountain West should remain warm and dry with high temperatures in the 70s commonplace on Saturday -- Southern California and Arizona may approach the 80s and low 90s. Several locations could set daily record high temperatures. On Sunday, the warmth will shift westward across the Rockies and into the Dakotas. High temperatures are likely to hit the upper 70s/near 80 across the Front Range, which is about 10-15 degrees above average for this time of the year and near daily record highs. The dry and breezy conditions should contribute to an enhanced fire weather risk across southeast Wyoming and Nebraska on Sunday.
