Another Good One (Mostly)
In general, we’ve had really nice weather for the past seven weekends in a row. And that has been the case from the Poconos to the Shore. This weekend, we’re most sure about the Poconos and the western suburbs of Philadelphia, but least sure about the Jersey Shore and Delaware beaches.
It’s been very muggy for the past couple of days, and now a cold front will be bringing relief…to most of us. At the Jersey Shore and Delaware beaches, it may stay humid all weekend (although not quite as bad as it is now). And some showers may actually return to areas near the shore on Sunday.
Blocking the Exit
Drier air will certainly move in gradually Friday afternoon and night, setting the area up for yet another very nice day Saturday. But we may not be seeing a repeat Sunday. Take a look at the computer forecast maps:
Note the high pressure centered just north of Pennsylvania. Normally with a position like that, the showers just off the Jersey Shore would continue to move out to sea. But also look at the bottom right. That’s an area of low pressure (either tropical or sub-tropical, but it doesn’t matter). Now look at the Sunday map:
The high has disappeared by Sunday, while the LOW has gotten much closer to us. In effect, the LOW is “pushing” the moisture back toward our area, and blocking it from continuing out to sea. The LOW will move away from land Monday, so it’s not a direct threat. But it indirectly may cause more clouds and even a shower threat Sunday, especially in New Jersey.
(And, in case you were worried, “Danny” will have absolutely NO impact on the U.S. East Coast this weekend).
