Potential Winter Storm For SE Wyoming Wednesday

Potential Winter Storm For SE Wyoming Wednesday

National Weather Service hydrologists calculate river levels by measuring the soil's moisture, how much snow is on the ground, the current and forecasted temperatures and what precipitation is expected to come. On average we are looking at sustained winds between 15-25 miles per hour with gusts over 35 miles per hour.

Forecast models show the storm system increasing in strength and it could produce a blizzard of record proportions between Wednesday and Friday, meteorologists say.

However, our confidence is increasing for a swath of heavy snow across parts of the High Plains, northern Plains and upper Midwest from Wednesday through Friday, including parts of Wyoming, Nebraska, South Dakota, far northern Iowa, Minnesota, Wisconsin and northern MI. The Watch is in effect from Wednesday through Thursday (April 10-11).

According to the NWS outlook from the Grand Junction office, the unsettled pattern will last into the weekend.

Wednesday night: Up to 6-8 inches of snow is expected to fall in western Minnesota, with just a couple of inches of slush in the metro as we dance with wet snow, rain, sleet and freezing rain throughout the night.

While we have the chance for rain showers on Thursday, I believe much of the day will be dry. That, plus melting of any snowpack left behind in the days after the storm, would only aggravate and prolong the ongoing flooding.

"The more snow we get, the better from this scenario because the water will enter the rivers and tributaries slower than if it was just 2 or 3 inches of rain", Hewitt said.

"It's essentially a thunderstorm, but it's cold enough for snow", Connelly said. "The snow will expand into the Upper Great Lakes overnight Wednesday", says the NWS's Weather Prediction Center.

In the warmer air to the south, severe weather could break out Wednesday afternoon and evening in parts of Kansas and Nebraska. One last round of snow shoveling for the season also is possible. This is a complex storm system with a lot of things that could change, so stay tuned for the latest updates. The high winds are expected to create waves of 15-20 feet or more, which is likely to cause flooding, erosion and other damage along the shoreline.

Overall, 1 to 3 inches of slushy accumulation is possible across southern Wisconsin with the higher totals towards central Wisconsin. The Wednesday evening commute will be very hard if not impossible. "And then travel on Thursday morning is expected to be tough when it comes to visibility due to blowing snow".

Highs on Monday will range from the high 20s in the north to the low 40s in the south.
