STORM HITS THE PLAINS

Storm Map: Major Storm Threatens the Central United States

Forecast period: Monday and Tuesday, November 2–3, 2026

A Major Storm System Takes Shape

The latest 4070 storm map is highlighting the potential for a significant storm system to develop across the central United States early next week. This system could bring two very different weather threats, with heavy mountain snow developing across the Rockies while severe thunderstorms become possible farther east across the Plains and Mississippi Valley.

The developing area of low pressure will help organize a powerful storm system, drawing moisture northward from the Gulf of Mexico while colder air advances southward and eastward behind an approaching cold front. This contrast in air masses will create the ingredients for a potentially active period of weather across a large portion of the country.

Severe Weather Threat: Texas to the Midwest

The greatest concern on the current map is the broad area of severe-weather potential extending from Texas and Oklahoma northeastward through Kansas, Missouri, Arkansas, and portions of the Midwest.

As warm, humid air moves northward from the Gulf, atmospheric instability could increase ahead of the approaching cold front. Thunderstorms may develop and organize into larger clusters or lines as the system strengthens.

The storms could produce damaging winds, large hail, and potentially tornadoes. Some storms may become strong or severe, particularly where the strongest instability and wind shear overlap.

The threat area is extensive, and the exact placement of the most significant severe weather remains uncertain this far in advance. However, the overall setup warrants close attention as we approach Monday and Tuesday.

Heavy Snow: Rockies and Front Range

On the western side of the storm, colder air will interact with moisture and developing precipitation to produce a significant snowfall threat across portions of the central and southern Rockies.

The current map highlights heavy snow across parts of Wyoming, Colorado, and New Mexico, including higher elevations and portions of the Front Range. Some snow could extend into lower elevations depending on how quickly colder air arrives and how the storm develops.

Mountain communities could experience accumulating snow, while travel conditions may deteriorate in areas receiving heavier snowfall. The combination of snow, wind, and colder temperatures could create difficult conditions across higher elevations.

The Storm Track and Timing

The system is expected to organize across the central and southern Plains before progressing northeastward. The position of the low-pressure center and the timing of the cold front will be critical in determining where the heaviest precipitation and strongest thunderstorms develop.

Areas ahead of the front will have the greatest opportunity for warm, moist air and thunderstorm development. Behind the system, colder and potentially unsettled conditions will spread across the Rockies and Plains.

What We Are Watching

There are several important details that will become clearer over the next few days:

• The strength and eventual track of the developing low-pressure system.

• How much Gulf moisture returns into Texas and the central Plains.

• The amount of instability available for severe thunderstorm development.

• Whether storms organize into a larger line capable of producing widespread damaging winds.

• The potential for isolated tornadoes within stronger thunderstorms.

• The extent of accumulating snow across the Rockies and Front Range.

The Bottom Line

Monday and Tuesday could bring a major weather event to the central United States, with severe thunderstorms developing across a broad corridor from Texas and Oklahoma into the Mississippi Valley and Midwest. Damaging winds, hail, and tornadoes will all need to be monitored.

At the same time, heavy snow could develop across portions of the Rockies, including Colorado and parts of the Front Range.

This is an evolving forecast, and the exact impacts will depend on the storm's track, strength, and timing. The next several model cycles will be important in determining where the greatest threats develop. We will continue monitoring this system closely as it moves closer to the forecast period.
