Snow, Cold to Reach Plains by Midweek

April 29, 2013; 5:53 AM

A strong surge of cold air diving through the Plains early this week will bring more snow to the central Rockies and High Plains.

This surge of cold air and its associated cold front are currently tracking into western British Columbia.

The leading edge of the cold air moving into the northern Rockies on Monday will produce a round of significant wind in central Montana.

Wind gusts of greater than 65 mph are possible on Monday from Cut Bank to Great Falls and Butte, and these gusts can create hazardous travel conditions for drivers of high-profile vehicles.

The cold air will continue to drive southward into Tuesday, causing temperatures to drop between 15 and 20 degrees across Wyoming and the western part of the Dakotas, compared to Monday's highs.

According to Expert Senior Meteorologist Alex Sosnowski, "The cold will drive quickly to the south but will move more slowly to the east."

Some rain will accompany this drop in temperatures for areas that don't need it along the Red River Basin. Though average rain amounts Monday afternoon into Monday night or Fargo and Grand Forks will only average 0.25-0.50 of an inch and are not likely to add significantly to flooding problems on that river basin.

Meteorologist Anthony Sagliani discusses the acceleration of the Red River flooding due to substantial snow melt that began late last week.

More Snow for Denver

As AccuWeather.com Meteorologist Erik Pindrock stated earlier this weekend, "If everything comes together, the mountains to the west of Denver could receive a foot or more of snow on Wednesday, while the city picks up several inches."

It begins to get a bit more complicated in Denver where AccuWeather.com meteorologists are forecasting almost record-high temperatures on Monday. Our forecast high of 82 degrees would be just shy of the record of 83 from the year 1948.

While enjoying the near-record warmth, residents will find it hard to believe that they may need the snow shovel within 48 hours. As residents know, almost anything can happen in Denver during the spring and the airport actually averages 1.1 inches of snow during the month of May, which makes this snow forecast hardly uncommon.

In fact, Denver's snowiest May in history occurred in 1898 when 15.5 inches of snow fell. While we aren't expecting anything like that with the Wednesday storm, there can certainly be a couple of inches of accumulation.

As the surge of cold air continues to dive southward, it will move into Denver and the Front Range, causing temperatures to drop into the 30s by Wednesday morning.

The cold air combined with an easterly wind flowing up the mountains will lead to the development of the aforementioned snow!

Severe Weather Threat Farther South and East

The clash of cold air against warmer air over the middle of the nation will contribute toward the development of severe thunderstorms.

The first storms were firing over Iowa and Wisconsin Monday morning. Additional storms will occur in the zone from Kansas to Wisconsin into Tuesday, with more storms farther south during the middle of the week.

AccuWeather.com meteorologists are pinpointing a zone from near Oklahoma City, Okla., to Wichita Falls, Abilene and near Dallas, Texas, for severe weather later Wednesday.
