Thunderstorm Outbreak Expected Tonight

Discussion: Today should be the stormiest day of this entire rainy and stormy stretch. Much of today will be spent in a warm sector with S flow ahead of a storm front. Isolated-to-scattered storm cells are possible today before the main event tonight. They would likely be isolated-to-scattered and very hit or miss.

The main storm front should then pass through later tonight. I will try my best to update timing later today. But as of right now, the storm front should knock on WNJ’s door around 7pm, push across NJ from W to E between about 8-10pm then clear ENJ completely by 11PM. The actual period of storms and downpours will likely only be a 30-60 minute event that pushes through your area between that general 7-11pm window. Again, WNJ first and ENJ last.

Standard thunderstorm concerns are in place today and are the most probable outcome. This includes periods of heavy rainfall, capable of producing flash flooding, and gusty winds. There are also more severe, but less probable concerns, such as severe winds, hail, and an isolated tornado or two.

Today’s storm front will be mainly from linear frontal energy attached to a low over the Great Lakes. Once the storm front pushes through by midnight tonight, it should then usher in a less humid/more comfortable air mass into NJ for Tuesday through Thursday/Friday. Then by the weekend we should return to heat and humidity.

In English: Expect a cloudy and stormy day for the most part. Storms should just be isolated during the day but then a main event storm front should push through NJ from about 7pm to 11pm from W to E. Heavy rain, gusty winds, and lightning are likely for most areas. Severe winds, hail, and a tornado or two are less likely/more isolated but definitely on the table as a non-zero chance. Tonight is one of those nights you’ll want to have candles/flashlights ready if you lose power. You’ll also want to pay attention to any NWS warnings for severe thunderstorms or tornadoes. I’ll put a weekly outlook out tomorrow for the rest of the week. For now, the concern is focused on tonight’s storm front. Be safe! JC
