🚨 𝗦𝗘𝗩𝗘𝗥𝗘 𝗧𝗛𝗨𝗡𝗗𝗘𝗥𝗦𝗧𝗢𝗥𝗠 𝗪𝗔𝗧𝗖𝗛 🚨

Scattered severe thunderstorms are expected to develop late this afternoon and especially this evening. The main window looks to be 𝟲 𝗣𝗠 𝘁𝗵𝗿𝗼𝘂𝗴𝗵 𝗺𝗶𝗱𝗻𝗶𝗴𝗵𝘁.

𝗣𝗿𝗶𝗺𝗮𝗿𝘆 𝘁𝗵𝗿𝗲𝗮𝘁𝘀:
• Damaging wind gusts (scattered gusts up to 𝟳𝟬 𝗺𝗽𝗵 possible)
• Large hail (up to 𝗽𝗶𝗻𝗴-𝗽𝗼𝗻𝗴 𝘀𝗶𝘇𝗲)
• Frequent lightning
• A tornado or two cannot be ruled out
• Brief heavy rain (limited flash-flood risk because storms should move fairly quickly)

Storms will develop along a front to our north and then track south-southeast through the region this evening. 𝗗𝗮𝗺𝗮𝗴𝗶𝗻𝗴 𝘄𝗶𝗻𝗱𝘀 are the biggest concern, with hail and a brief tornado also possible.

I’ll post updates in the comments for now. If severe weather moves into Hunterdon County, I’ll put up a new post.

𝗧𝗵𝘂𝗿𝘀𝗱𝗮𝘆’𝘀 𝗦𝗲𝘃𝗲𝗿𝗲 𝗪𝗲𝗮𝘁𝗵𝗲𝗿 & 𝗙𝗹𝗼𝗼𝗱 𝗧𝗵𝗿𝗲𝗮𝘁 ⛈️

A warm front will lift through the area Thursday morning, bringing showers and thunderstorms. The timing of that front will set the tone for the rest of the day.

If it moves through quickly, the afternoon will have a better chance of additional showers and storms, and the severe weather threat will be higher. If it stays cloudy and rainy, the severe threat will be lower.

The Storm Prediction Center has us under a Slight Risk for severe thunderstorms. Damaging wind gusts are the primary threat, with isolated hail and a brief tornado also possible.

The Weather Prediction Center has us under a Slight Risk for excessive rainfall, and a Flood Watch is in effect from Thursday afternoon through late Thursday night. Some of us may see 1 to 2 inches of rain, with locally heavier amounts possible in thunderstorms.

Isolated to scattered flooding is most likely in urban areas, poor drainage spots, and along smaller streams. Never drive through flooded roads.

I’ll keep a close eye on things and will have an update in the morning. Thanks for reading and have a great night!

A line of heavy showers and strong to severe thunderstorms is currently moving through eastern Pennsylvania into New Jersey.

Closer to the Hunterdon County area, the severe weather threat is lower. However, the risk of heavy rain remains elevated and could lead to localized flooding.

The heavy rain and severe weather threat will gradually diminish from west to east this evening. Conditions should dry out overnight and remain mostly dry through Friday, with the next chance of rain returning on Saturday.

Heavy Rain & Storms Expected This Afternoon & Evening ⛈️🌧️

The National Weather Service has issued a Flood Watch for Hunterdon County from noon today through late tonight (until 2 a.m. Friday). Multiple rounds of showers and thunderstorms are expected later today as a cold front moves through the area.
