Figure 1 depicts the surface observations at 8:00 pm EDT, which shows a cold front moving across the northeastern United States. Warm air advection, aided by low pressure in western Massachusetts, triggered thunderstorms in the evening hours of February 25th, which ultimately led to two EF1 tornadoes across the state.
