Quiet Weather Today…but Severe Storms and Heavy Rain this Weekend

I have to say, I certainly have enjoyed the nice weather most of us in the Southeast have been experiencing at least the past week and a half. Unfortunately, it was a different story earlier this week in Arizona when at least four tornadoes touched down in the northern part of the state early Wednesday morning. According to authorities, about 200 homes were damaged and seven people were hurt. The National Weather Service said that winds in the Bellemont area, which is just west of Flagstaff, were between 80-110 mph during the storms. Businesses were damaged and about 28 cars of a freight train were derailed.

Thankfully, the next several days look to be quiet across Arizona with high pressure over the area. Lots of sunshine is expected in the Bellemont area with highs in the 60’s. Hopefully this will help aid in the cleanup efforts.

As for the rest of the U.S., an area of low pressure and its associated cold front will move across the Plains tomorrow. Conditions will be favorable for isolated severe storms across the Dakotas and Nebraska. Severe storms will be capable of producing damaging wind gusts, hail, frequent lightning and isolated tornadoes. Elsewhere, a storm system will push into the Pacific Northwest bringing the threat for heavy rain. Looks like western portions of Washington and northwestern Oregon could pick up 2-4” with isolated heavier amounts up to 6 inches.

As we head into Sunday, the threat for heavy rain will end across the Pacific Northwest, but we’ll continue to track the cold front across the Plains moving into the Midwest. With plenty of moisture and instability in place, isolated severe storms will be possible. The main threats will be damaging wind gusts, frequent lightning, hail and an isolated tornado. Elsewhere across the country, strong high pressure will still be in place across the eastern U.S. Lots of sunshine’s in the forecast from New England into the Southeast. Also, quiet weather is expected across the four corners region. This of course is welcome news after the storms they saw earlier this week with the upper level disturbance.
