Christopher Ensor gets drenched by a water bucket while his daughter Shelby sprays him and daughter Caitlin runs around Saturday at Sanger’s new Switzer Park Splash Pad. Afternoon temperatures reached the high 90s on Saturday, but a cold front is expected to reach the area Monday night.

Cold front expected Monday night; week should also bring rain

The temperature swing isn’t likely to send many North Texans to the back of the closet in search of sweaters.

But, after the mercury flirts with a high of 100 degrees Monday afternoon, meteorologists expect a drop of more than 30 degrees with overnight lows in the upper 60s by Tuesday night.

A cold front is expected Monday night that will bring much cooler temperatures through the end of the week, said Jesse Moore, a meteorologist with the National Weather Service.

Between Monday and Wednesday, temperatures in the Midwest will be as much as 15 degrees cooler than normal, with the biggest drops seen close to the Great Lakes. The clouds and rain expected behind the front will keep temperatures cool in Denton County and the rest of North Texas, Moore said.

High temperatures in the area Wednesday through Friday are expected to be in 80s.

“Without the clouds, it would creep back up into the lower 90s,” Moore said.

Rain should be widespread, Moore said, with many areas getting an inch of rain or more.

Meteorologists have become increasingly confident with the unusual pattern because it has been showing up in their models for several days now, Moore said.

Typhoon Neoguri, which became a “super typhoon” when its winds reached 150 mph, has altered the path of the North Pacific jet stream, allowing polar air behind a trough of low pressure to spill out of Canada and into the Midwest, according to Jeff Masters, the meteorology director at Weather Underground.

While similar to the polar vortex pattern last winter that broke cold weather temperature records in numerous states, there are key differences, Masters said. This air mass is coming from western Canada and not directly from the Arctic, plus the polar vortex is not nearly as strong in the summer — and sometimes breaks down completely.

Meanwhile, Seattle and the usually temperate Pacific Northwest will be affected by the shifting jet stream differently. Highs there could reach 90 or higher next week.
