Tuesday Overview: After rain, heat builds this week

/by

We hope you had a great July 4th weekend! The weather cooperated for most part for outdoor activities over the holiday weekend. But rain with a wave of low pressure moved into the region overnight. Some areas received 0.50″ to 1.50″ of rainfall including parts of Central NJ, NYC and Long Island. Which will only put a small dent in moderate drought conditions in the area. Other areas, especially further north have seen much lighter rainfall.

Rain is now ending from west to east over the region this morning. A ridge building over region will cause skies clear for more sunshine this afternoon. Temperature will rise into in the middle to upper 80s. Humidity levels will remain high. Thus, there is slight chance that that a shower or thunderstorm could still pop up around the region later this afternoon or early evening. However, the ridge will continue build with hotter and humid conditions likely for the rest of the week. Some thunderstorms may also be around as well. Here are some highlights for later this week:

Major rains possible through Tuesday, may impact fireworks

A well advertised frontal boundary, and associated low pressure system, are forecast to move toward the area from Monday Night into Tuesday — and it may impact fireworks displays. While forecast models have fluctuated a bit with the exact placement of the storm system, the overall signal for heavy rainfall potential has been quite strong. Over the past 24 hours, models have come into further focus in regards to the eventual evolution of the storm system in our area.

A large plume of moisture will move northward through the Southeast States, eventually meeting up with a very pronounced frontal boundary and temperature/pressure gradient from the Ohio Valley into the Mid Atlantic states. Meanwhile, a disturbance moving along this gradient will provide ample lift for precipitation to develop. The juxtaposition of these features will lead to steady rainfall, spreading from the Ohio Valley to the Mid Atlantic on Monday.
