NOAA - NWS Issues Fresh Warnings for Multi-Hazard Weather Conditions Across the United States Until Friday

US meteorologists have issued their latest short-term weather forecast.

It includes fresh warnings for multi-hazard weather conditions such as severe weather, fire weather, and a major storm system that is currently causing a blizzard across the Contiguous United States (CONUS).

Latest Forecast

The National Oceanic and Atmospheric Administration (NOAA) - National Weather Service (NWS) has issued fresh weather warnings for potential life-threatening and disruptive weather hazards from mid-week and before the weekend.

The hazards include significant severe weather conditions, including thunderstorms and isolated tornadoes; intense wildfires triggered by dangerous fire weather conditions; and further risk from the ongoing snowstorm due to the weather disturbance.

Its latest "short-range public discussion" was posted on the US weather agency's Weather Prediction Center (WPC) on Tuesday, April 12, and is valid from Wednesday to Friday, April 13 to April 15.

However, the forecast and warnings within the said "discussion" may be updated or changed in the coming days.

Significant Severe Weather

Severe storms with potentially heavy rain and flash floods are possible from the Lower Mississippi Valley to the Midwest via the Lower Ohio Valley throughout Wednesday.

Related weather events, such as twisters, may occur in the valley from Memphis to Louisiana.

Widespread damaging winds, coinciding with a moving cold front and large hail, are also one of the deadliest hazards of adverse weather.

The NOAA - NWS said there is a "Slight Risk" for torrential rain and flooding in the region.

As the storms pass through a cold front, they will yield a significant downpour of rain along their path.

In addition, the NOAA's Storm Prediction Center (SPC) noted that the "Moderate Risk" of the severe thunderstorms may wreak havoc from eastern Nebraska, Iowa, southern Minnesota, and southeastern South Dakota.

Dangerous Fire Weather Conditions

In the Western US, fire weather will also set conditions for increasing the growth and spread of wildfires.

One of these factors includes widespread sustained winds of up to 20-30 miles per hour (mph), said the NOAA - NWS.

Air humidity, soil moisture, and drought are also the main indicators of fire weather.

In addition, the SPC also issued a warning for "extremely critical" fire weather conditions, affecting the Permian Basin into southwestern Kansas.

Meanwhile, critical fire weather will pose a threat to parts of central and southern High Plains.

During a wildfire, the hotspot areas are forested or grassland areas. The spread of flames may transpire with little or without warning.

Major Storm System

A system is causing a major winter storm, bringing heavy snow and blizzard conditions, to parts of the Northern Plains, and this may continue until Thursday, April 14, based on the NOAA - NWS short-range forecast.

The accumulation of snow is expected to be between 1 foot and 2 feet from eastern Montana into the western-northern parts of North Dakota. It may reach as high as 2 to 3 feet.

Snow showers, along with a stationary front, have been forecasted through the central-northern Rockies and into the Pacific Northwest.

Moreover, the occurrence of related blizzard conditions, with a deadly combination of heavy snowfall and strong winds, are likely in the Central US, as per USA Today.
