Weather Forecast Discussion

Very humid with showers and some strong storms today

Improvements for the weekend

TODAY: Mostly cloudy and humid; scattered showers and t-storms, one round early this morning, another round later this afternoon and evening, a few storms could be strong. High: 84

TONIGHT: T-storm this evening; clearing late; warm and sticky. Low: 68

TOMORROW: Sun and clouds; less humid in the afternoon; maybe a stray late day shower or storm. High: 87 Low: 64

We are tracking a few showers and t-storms early on this morning. Be careful of some locally heavy rain which could lead to ponding on roadways. It's a very warm and muggy start this morning. Many locations did not get below 70 for the overnight lows. We should see this initial round of showers and t-storms taper later this morning with mostly cloudy skies then taking us into the lunch time period.

Scattered showers and t-storms are expected again later this afternoon into the evening as a fairly potent cold front tracks in from the west. We’ll need to watch for a few t-storms containing locally heavy rain which could lead to flash flooding. Damaging wind gusts, large hail, and even an isolated tornado will need to be watched for as well. This may all be moving through during the evening commute. The Storm Prediction Center currently has the area highlighted under a "slight" risk for severe weather later today. That is a level 2 out of 5 for the threats mentioned above. The cold front and showers and storms tracking through look to move away to our east by 11pm tonight.

It continues to look like Saturday should be mostly dry. A weak upper level disturbance tracking through during the afternoon and evening may spark an isolated shower or t-storm but most probably don't see this. It will still remain a little humid Saturday although humidity should be slowly dropping during the afternoon and evening. Sunday looks to feature more in the way of sunshine with lowering humidity values as dry high pressure builds back in from the north and west. High temperatures both days this weekend will end up in the middle 80s.

Monday marks the long awaited and highly anticipated total solar eclipse. While we won't see totality in Pennsylvania and New Jersey (75% of the sun being covered by the moon), a first look at the Monday forecast suggests that the weather will cooperate for viewing the partial eclipse here with mostly sunny skies expected.

The tropics continue to heat up as they often do this time of the year. While Hurricane Gert continues to move well away from the East Coast out to sea, we need to keep an eye on several tropical waves out in the open Atlantic that have a chance to strengthen over the next several days.

**Flash Flood WATCH in effect from 2pm today through this evening for the Lehigh Valley, Berks County, Delaware Valley, and Western New Jersey
