A Warm-Up And Rain On The Way This Week

This is an archived article and the information in the article may be outdated. Please look at the time stamp on the story to see when it was last updated.

The cooler weather we had this weekend will stick around for the early part of the week as a big dip in the jet stream with bring relatively cooler temps to the area. This is called “northwest flow”. 

This dip in the jet stream will keep the warmer temps out to the west for the early part of the week, but the pattern will flip-flip by mid-week as a ridge starts to build over the area.

By Wednesday we will see afternoon highs well above average with 70’s and 80’s area-wide. Temperatures on Wednesday in the River Valley will be near record highs.

The jet stream pattern will start to break down on Thursday and into the weekend as a cold front pushes in from the north. Scattered showers and thunderstorms will be possible Thursday afternoon through early Saturday morning. This front will lift to the north on Friday into Saturday as a warm front as another system starts to organize to the west.

By Saturday an area of low pressure will develop to our west and will drag a cold front into the area late Saturday night. This is a look at the European (ECMWF) weather model (one of the more reliable models) for late Saturday night. This model has a line of stronger storms moving in late Saturday night. It’s a little too early to nail down any specifics on severe weather for the weekend but the possibility is there to see stronger storms. 

We typically see a peak in severe weather as we get into the month of May and longer range models are starting to show the possibility of a more active and stormy pattern by the end of the first week in May into the second week.
