This weather forecast describes a dynamic weather pattern across the United States over the next couple of days:
- Severe Weather Threat and Flash Flooding (Monday):
- Showers and thunderstorms are expected from the Southern Plains to the Middle Mississippi/Ohio Valleys, increasing the risk of severe weather and flash flooding.
- The presence of a deep upper-level trough over the West will contribute to this pattern.
- The Storm Prediction Center has issued Enhanced and Slight Risks for severe weather, including large hail, damaging winds, and tornadoes.
- Fire Weather Risk (Monday):
- A Critical Risk of Fire Weather is anticipated for the Southern High Plains due to very strong winds and dry conditions behind the dryline.
- Continued Severe Weather Threat (Tuesday):
- The storm system will move eastward, bringing widespread showers and thunderstorms from the Upper Ohio Valley to the Mid-Atlantic.
- The Storm Prediction Center has issued another Enhanced Risk of Severe Weather, particularly for large hail, damaging winds, and tornadoes.
- Flash flooding remains a concern, especially in the Ohio/Tennessee Valleys and Mid-Atlantic.
- Unsettled Weather in the West:
- Lower elevation rain and higher elevation snow are expected to continue but taper off through Monday.
- Some areas in the West, particularly southern Arizona and the central Rockies, may experience moderate to locally heavy rainfall and snowfall accumulations.
- Temperature Trends:
- Warm, above-average temperatures are likely for eastern/southern regions ahead of the approaching storm system.
- However, much cooler temperatures are expected in the Middle Mississippi Valley and Central/Southern Plains as a cold front moves through on Tuesday.
- Initially, portions of the Northern Plains and the West will experience much below average temperatures, but warmer conditions will gradually return as the trough moves eastward.
Overall, this forecast indicates a complex weather scenario with multiple hazards, including severe storms, flash flooding, and fire weather concerns, across different regions of the United States over the next few days.
