Warm Weather and Dry Air are Forecast for the Southeast; Lower Temperatures Expected in the North

Bryan Dijkhuizen

On Saturday and Sunday, a surface wave, which is presently moving through the Front Range, will evolve into a dynamic low-pressure system.

A warm front connected with this low will continue to send warm air into the Great Plains and Southeast today, before moving into the Midwest on Saturday and the East on Sunday, according to the National Weather Service.

Within this warm air mass, a dry line will emerge, stretching down across the Southern Plains and into the Midwest. This, combined with dry, windy conditions on the ground, will provide a major fire weather threat throughout areas of southern-eastern New Mexico, the Texas/Oklahoma panhandle, southeast Colorado, and most of Kansas during the weekend.

Throughout the Mississippi Valley and the Midwest, the danger of thunderstorm activity will grow as the low pressure system intensifies on Saturday.

There is a chance of severe weather, especially across Iowa and the remainder of the Upper Midwest, in certain locations. Supercell thunderstorms, which are capable of generating destructive winds, a few tornadoes, and hail, are possible.

Within 48 hours, as the dynamic Front Range system intensifies, it will provide light to moderate snowfall throughout most of the Northern Plains and into the Upper Midwest, according to forecast models.

A possibility for accumulation of freezing rain will be present across areas of the Upper Midwest this weekend, spanning from southern Minnesota through northern Wisconsin and into the Upper Peninsula of Michigan.

Some isolated regions may have more than a quarter-inch of ice on the ground. Precautions should be taken while traveling over the weekend.

On Saturday and Sunday, high pressure on the backside of this storm will bring freezing air to the Northern and Central Plains, with maximum temperatures expected to be 20-30 degrees below normal in many locations.

Troughing in the west may bring moderate to heavy mountain snow to sections of the Sierra Nevada, Great Basin, and Central/Southern Rockies this weekend, according to the National Weather Service. Rainfall at low elevations is also forecast in these areas as well.

The warm air mass that is now focused over the central section of the nation will move eastward this weekend before settling over the eastern half of the country on Sunday and Monday morning. As a consequence, it is possible that new high and low temperature records may be tied or broken.
