According to official estimates National Weather Service (N.W.S.(SPC, for short) and the Storm Prediction Center (SPC, for short), A Low pressure development Over the southern plains A An episode of heavy rain and intense electrical activity throughout Monday. This phenomenon will be organized thanks to the contribution of warm moisture from the Gulf of Mexico, which will enhance surface instability and allow strong storms to form.
all day long, The tape most at risk would be the Ark-la-tex tapeWhere they will be combined Rainfall with wind blowing. SPC will retain “Slight risk” for most of East Texashe North Louisianahe South Arkansas and Western Mississippi. Expected possibilities will include short-lived thunderstorms, damaging storms, and hail, a scenario that will intensify in the afternoon.
In this context, the National Oil Authority announced this Certain sectors of Texas that were previously affected by heavy rainfall will be affected again vulnerable to overtaking Suddenly due to the saturation of the terrain. The advance of the cold front from the west, in conjunction with a warm front moving north, will generate a lifting mechanism that will enhance the intensity of the showers.
towards the night, The disturbance will move into the Tennessee Valley and inland areas of the Southeastwhere large storms will also develop, although the risks are limited compared to what will dominate the far south during the first half of the day.
While the south will face severe storms, The north will experience a long ring of snow It is connected to a scissor type system that will move quickly From the Rockies to the Midwest. This wintry pattern will begin Monday near the Canadian border, in Montana, where the first flakes will accumulate starting in the afternoon.
Nuclear-weapon states will expect this Snow continues to fall throughout the night and extends to the northern plains on Tuesday. Forecasts will indicate that many locations in this area may receive several inches of snow as the system advances. It will also take a while for the disorder to progress Noticeable increase in wind intensityWith gusts that may reach high values and reduce horizontal visibility, especially along the corridor north of the center of the system.
Tuesday night and Wednesday morning, Snow will reach the upper Great Lakes regionThe clipper will go deeper and gain more extension. The gradual increase in wind will generate particularly uncomfortable conditions, with very low thermal sensations and difficult movements in open areas.
In parallel with these systems, Another front will enter the Pacific Northwest on Monday. New disruption will result Widespread rain on coastal sectors and falling in the form of wet snow At higher altitudes. Heavy snowfall is possible on the peaks of the Northern Rockies and will combine with a windy environment that will complicate traffic on mountain passes.
All day Tuesday, This front will pass through the interior of the west and leave a continuing wintry pattern. By the end of the day, a new Pacific system will enter the same region, starting a second episode of low-level rain and snow in mountainous areas.
In contrast to the winter and storm scenarios in the west and south, respectively, Most of the eastern and central United States will see unusually high temperatures By the end of November. The expected signs for this Monday will reach usual values at the beginning of fall or even late summer in several regions.
The maximum expected will be:
he The cold front advances from the west It will cause a Gradual decrease in calorific valueswith a noticeable entry of cold air that will push towards 30 degrees Fahrenheit (−1 degrees Celsius) on Tuesday in several areas of the north and eastern interior.
In the west, temperatures will remain within normal levels Maximum temperatures range between 60°F (15°C) and 70°F (21°C) in Southern California and the Desert Southwestbetween 50°F (10°C) and 60°F (15°C) on the west coast, and between 40°F (4°C) and 50°F (10°C) in the mountainous interior.
