For those who were sick of the heat, today will be a gift: A cooler, less humid day. You can thank a backdoor cold front that has pushed into Delaware River Valley this morning. Mostly cloudy skies and onshore winds are anticipated for much of the area for the remainder of the day. This will keep temperatures from rising out out of the lower to middle 70s. Low pressure tracking north of region will try to push this front back east as a warm front this afternoon. This could cause skies to clear for sunshine and temperatures to rise into the 80sover Western and Central parts of New Jersey, later this afternoon. However a secondary low will developing south of region this evening, will likely keep this frontal boundary moving through the rest of region today.
Some scattered showers and thunderstorms are possible, with this frontal boundary, mainly during the late afternoon and evening hours. SPC has issued marginal and slight risks for western parts of region today. Stronger shear with an associated upper-level trough, will support more organized convection to develop over Eastern Pennsylvania . However, instability will be lacking over much of the region today. The best chance for strong or severe thunderstorms, is over Western or Central parts of New Jersey. This is where surface-based instability could increase with some clearing possible later this afternoon. While a more stable marine layer, will more likely cause thunderstorms to weaken as they move further east over rest of region. Some heavy rainfall and lightning is still possible. Some other highlights for this weekend:
- Not beautiful weather for the beach today. But if you are going,, beware there is a moderate risk for rip currents for many off the ocean facing shores today. Check out the surf zone forecasts more information.
- For Mets fans, there is a chance that showers or thunderstorms could cause delays for the Mets vs Nationals game tonight at Citifield. Check out the Sportscast page for more updates throughout the day.
