A warm and sunny day but not too humid

Increasing humidity and storm chances end of week

REST OF TODAY: Mostly sunny and warmer but lower humidity. High: 87

TONIGHT: Mostly clear and comfy. Patchy fog late. Low: 61

TOMORROW: Early patchy fog otherwise sun and clouds, slight chance for a late day shower or storm, humid. High: 85  Low: 69

We got off to a very foggy start this morning with temperatures in the 60s. A little bit of a breeze has picked up and this has helped to mix drier air aloft down to the surface scouring out the fog. Visibilities have definitely improved and we’re now looking at a mostly sunny day.

Wednesday will be the warmest, but also the best, day of this week with sunny skies and highs climbing into the upper 80s with tolerable humidity levels. The pleasant weather can be attributed to an area of high pressure sliding across the East Coast. For tonight, we should see comfortable sleeping conditions with low temps in the low 60s and likely some 50s for the Poconos. The high pressure system in control should make for mostly clear skies. While some fog will be possible again, it doesn’t look to be as widespread or as dense as what we saw this morning.

Thursday will be a warm day too but a little cooler compared to Wednesday thanks to some increasing clouds as highs reach into the low to mid 80s, but the dew points will be rising throughout the day so it will also be more humid. High pressure will keep things dry for most of the day, but as Thursday evening rolls around a few showers and thunderstorms will begin moving in from the west. The better chance for scattered shower and t-storm coverage right now looks to be late Thursday Night into early Friday Morning.

The shower and thunderstorm activity will continue through Friday Afternoon with higher humidity levels helping to fuel the instability in the atmosphere. It certainly won't rain all the time, but the week will end on a seasonably warm, sticky, and unsettled note. Any severe concerns look to be fairly low at this time but a few t-storms could still have gusty winds and localized downpours.

Similar to last weekend, the cold front associated with the showers and thunderstorms may move through relatively early in the day on Saturday. This frontal passage may not completely eliminate the threat for an isolated shower or thunderstorm for the rest of the day, but what it will do is allow skies to clear for some sunshine. 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 to upper 80s.

Next Monday marks the long awaited and highly anticipated total solar eclipse. While we won't see totality in Pennsylvania and New Jersey, a first look at the Monday forecast suggests that the weather will cooperate for viewing the partial eclipse here with at least partly sunny skies expected.

Hurricane Gert remains well off the East Coast of the United States. Gert is tracking northeast and recurving out to sea. It poses no threat to land; however, Gert is expected to bring strong rip currents and rough surf to the Mid-Atlantic beaches over the next 24 hours. Those that are beach-bound should note the higher risk and only swim in the presence of lifeguards.
