Midday Zones Update: Heavy Rainfall and Severe T-Storm Threat This Afternoon

/by

Happy Thursday! Low pressure currently over the Ohio Valley is attempting to push warm front north form Mid-Atlantic region. But instead a triple-point low will form over Mid-Atlantic region, along the warm front.  A strong low-level jet, mid-level vorticity, low-level moisture convergence with firehose of Atlantic and subtropical moisture will lead another rounding of heavy rain with embedded thunderstorms. Especially south and west of NYC.

Evening All Zones Update: Heavy Rain and Flash Flooding Thursday

/by

After nice Spring weather made an appearance on Wednesday, things are about to quickly go downhill during the overnight and into Thursday. A very expansive and classically synoptically deepening storm system will trek its way towards our area. With it, a few rounds of heavy rain, rumbles of thunder, and flash flooding are likely.

The storm will cut itself off from the atmosphere at the mid-levels, which allows synoptic features for ascent to remain in-place for a longer period of time. Thus, unlike Tuesday where it was one quick wave of heavy rain with the warm front and then only isolated to scattered showers and thunderstorms behind it, this storm should feature multiple waves of heavy bands of rain that last a decently long time.

Similar to Tuesday, however, is the evolution of a warm front out ahead of a system pushing our way and tapping into a low-level jet for lift and moisture. This is how the first batch of rain will move into the area during the late-overnight and early-morning hours.
