Mild air reaches East Coast as busy weather pattern develops – Everett Post

By DANIEL MANZO, ABC News

(NEW YORK) – The mild air continues to build in the central United States and will expand into parts of the east coast on Tuesday.

As of Monday, many cities in the central United States were nearly 20 degrees or higher above average. Chicago reached 62 degrees – a full 19 degrees above average – while Kansas City reached 73 degrees, which is 21 degrees above the city average. Denver hit 69 degrees, which is 17 degrees above average, and Sioux Falls hit 66 degrees, just below their record of 69 degrees.

Record highs are possible in the upper Midwest and parts of the plateau from the Texas Panhandle to northern Minnesota on Tuesday.

Afternoon temperatures could be up to 30 degrees above average, with widespread temperatures expected in the central US in the 1970s and even the 80s, and even in northern regions like Minneapolis and Chicago in the 60s.

On Tuesday the mild air expands into parts of the east and a high of 62 is forecast in New York. The last time New York was in its low 60s was in December.

For the northeast, however, this is just the beginning. Temperatures will range into the upper 60s and maybe even 70s on Thursday and Friday, making this air easily the warmest air for the region since November.

Unfortunately, the US’s mild and relatively calm weather stretch is nearing its end as a Pacific storm on Tuesday will bring much-needed rain and snow to California.

Locally, Los Angeles will see over 1 inch of rain through Thursday, which can cause flooding and debris in the area.

In the mountains of Southern California, snow can be up to foot on site.

If this storm moves slowly inland it will spread snow to other parts of Intermountain West, allowing over a foot of snow locally over the mountains.

In the meantime, on Wednesday and through Thursday, a new storm will quickly develop and hurtle north in the central US

This storm will bring snow to parts of the Northern Plain, including places that are in the 60s and low 70s on Tuesday. All of the snow should stay north and west of Sioux Falls, South Dakota, and Minneapolis.

The storm will also trigger severe weather in parts of Kansas and northern Oklahoma on Wednesday night, and gusty winds and hail will be possible.

Then the storm from California will penetrate the southern United States on Friday and Saturday and is likely to become a long-range storm.

The impact includes a potential major Colorado snowstorm that sees Tuesday temperatures well past the 1960s.

Additionally, there is likely to be a multi-day severe weather threat, including the threat of tornadoes, in the southern plains as more rounds of rain spread across Oklahoma to Indiana, which can lead to flooding.
