Edison, New Jersey
Reviewed local trend guide
Temperature swings can be larger than the current reading suggests
Compare the current observation with the hourly trend and the day’s high and low. Fronts moving through central New Jersey can change temperatures, humidity, and wind during the same day.
Check the current ZIP data →Rain timing matters for the Route 1 and Turnpike commute
Use hourly precipitation chances and radar together before commuting. A low ZIP-wide percentage does not rule out a brief local downpour, and heavier rain can quickly slow major roads.
Check the current ZIP data →Thunderstorm, flood, and winter alerts need separate attention
Check the exact alert type, affected area, and expiration time. Never treat a general forecast trend as a substitute for an NWS warning or local travel restriction.
Check the current ZIP data →Wind shifts can signal a front or coastal influence
Wind direction and gusts help explain fast changes in temperature and comfort. Stronger gusts also matter for trees, power lines, high-profile vehicles, and outdoor setups.
Check the current ZIP data →Seasonal daylight changes affect commute and activity timing
Use local sunrise and sunset with the hourly forecast when planning walks, school activities, and evening travel. In winter, check pavement temperature and official travel guidance as well as air temperature.
