Downpours Thunderstorms Firing Up On Radar
Heatwave Friday Through Sunday
Clouds are keeping temperatures subdued in most areas with temperatures in the upper 70s and lower 80s with the exception of Southern New Jersey where temperatures have reached the lower 90s. This has caused some showers and thunderstorms to bubble up going into this evening. Some heavy downpours are possible and where the ground is saturated some flash flooding is possible again in some of the heavier thunderstorms. Humidity remains very high. Once this system clears out to the east we will bring on the heat and the high humidity that will be with us through Sunday.
Regional radar shows the showers developing from Southeast New England southwestward into Southern Pennsylvania into parts of Maryland. We won’t see the widespread thunderstorm activity like we saw yesterday but with all the moisture around, rains could be locally heavy as these cells play through.
LOCAL RADAR NEW YORK CITY
There are no changes in the outlook from Friday through Sunday. Sunshine hot and humid conditions return Friday with most highs in the low to mid 90s. Saturday and Sunday will be very hot and very humid with highs in the mid 90s to near 100 and heat indices 110 or higher. Other than a pop up thunderstorm we should be rain free through Sunday after noon.
The frontal boundary that will bring relief from the heat will get closer Sunday evening to trigger off some thunderstorms inland but the main push will wait until Monday. High pressure dropping down from Canada brings real relief once the front passes. Monday won’t be as hot but it will still be in the 80s to near 90 with the likelihood for thunderstorms when the front passes. The front may get hung up for awhile on Tuesday with lingering clouds and showers possible early before we see some genuine clearing of skies. The humidity could start to lower a bit late Monday north and west of coastal areas but the main push will come once the front moves far enough south late Tuesday.
