PHILADELPHIA (CBS) — High pressure is firmly in control across the northeast, and we expect to see lots of sunshine this week.

After a cooler pattern, there will also be a midweek warm up. Temperatures will increase a few degrees each day, and there is an outside chance the mercury could hit 90 on Wednesday, which would make it only the 2nd 90 degree day in August (8/5). In contrast, there have been six days where highs failed to break out of the 70s! So much for the August heat.

Looking ahead, there will be a weak cold front that will pass through the Delaware Valley on Wednesday night. Other than that, there is no precipitation to speak of!

In the tropics, Tropical Storm Cristobal is churning to the east of the Bahamas. It is expected to strengthen in the coming days but curve out to sea, rendering it no threat to the United States. It will stir up the surf and elevate the risk of rip currents. If you plan to head to the beach today, the risk of rip currents will be high as well.

Today’s Highs:

Philly – 84
Shore – 78
Poconos – 77
