Temperature Patterns Across Continents
North America and Europe
During March 2019, North America experienced a sharp temperature gradient, with the Central Plains and Midwest often colder than normal while the Northeast saw above-average readings. In Western Europe, persistent southerly flows contributed to mild nights and frequent precipitation, pushing monthly temperatures upward compared to the long-term mean.
Asia and Polar Influences
East Asia endured below-average temperatures as polar air dips reinforced cold outbreaks, particularly across Japan and the Korean Peninsula. The Arctic Oscillation shifted between positive and negative phases, modulating how far cold air spilled into mid-latitudes and influencing day-to-day temperature swings.
Precipitation and Snowfall Trends
Storm Tracks and Rainfall
March 2019 featured an active storm track across the southern and central United States, fueling above-average rainfall and a major river flooding event by month's end. In contrast, parts of the West and high-latitude regions dealt with drier conditions, with snowfall lingering in mountain ranges and at higher elevations.
European and Asian Wet Episodes
Western and Northern Europe recorded well-above-average precipitation, leading to saturated soils and localized river rises. In East Asia, frequent winter storms brought heavy snow to coastal areas, while interior sections remained relatively dry under blocking patterns that shifted storm tracks northward.
Regional Extremes and Noteworthy Events
Flooding in the Central United States
By late March, rapid snowmelt and heavy rainfall in the Central US triggered significant flooding along major river basins, affecting agriculture, transportation, and community infrastructure. This event stood out as one of the most impactful weather-related episodes of the month.
Severe Weather in the US Southeast
The southeastern United States saw several rounds of severe thunderstorms, including tornadoes, large hail, and damaging wind gusts. These outbreaks were associated with strong upper-level dynamics and ample moisture streaming northward from the Gulf of Mexico.
Key Takeaways for March 2019 Weather
- A sharp temperature contrast across North America defined the month, with cold in the Central Plains and warmth in the Northeast.
- Western Europe experienced notably wet and mild conditions linked to a south-shifted jet stream.
- Above-average rainfall in the Central US set the stage for major flooding by month's end.
- East Asia faced colder-than-average temperatures and impactful winter storms, especially in coastal zones.
- Severe thunderstorms in the US Southeast highlighted the volatility of spring transition weather.
FAQ
Reader questions
How did March 2019 temperature patterns compare to recent years?
March 2019 fit within a broader pattern of variable winters and transitional springs, with some regions notably colder than the preceding mild season yet not as extreme as earlier years in the decade.
What role did storm tracks play in the flooding in the Central US?
A southerly storm track funneled repeated rounds of heavy rain and slow-moving systems over the Central Plains, while lingering snowpack from winter melted rapidly, overwhelming river capacities.
Were there any record-breaking events during March 2019?
While not global records, several regional daily precipitation and river height records were tied or broken, especially in areas where rainfall totals over multiple days reached historic levels for late winter.
How did the Arctic Oscillation influence March 2019 weather?
Fluctuations in the Arctic Oscillation helped determine how frequently polar air invaded mid-latitudes, contributing to alternating cold snaps and milder periods across the Northern Hemisphere throughout the month.
