July 13: Humidity And Rain Continue, Heat To Return

As expected, the area mainly stayed dry from 5 PM until now, however there is much more rain to come tonight, especially for the southern and eastern parts of the area. The rain continues until tomorrow, when it should be dry again, however there should be no relief for both the short term and long term, as heat and humidity should make a return later this week.

Tonight’s Outlook:

The heavy rain currently in Maryland and Pennsylvania should continue to move ENE, however it is uncertain how it affects the area. The main band of rain split, with the southern and western ends intensifying, and the middle part, apparently moving towards the NYC area or west of NYC, weakening into light rain.

There should be more rain behind that area, however, as the area of rain in south central PA should affect our area later tonight, bringing widespread moderate to heavy rain. The majority of the rain should fall in the southern and eastern parts of the area, where another 1 to 2 inches of rain are possible, with amounts between 1/2 and 1 inch for the rest of the area, locally reaching 1-2 inches.

Tomorrow’s Outlook:

Tomorrow will be another rainy day across the area, especially in the morning. By the late afternoon, the storm should mainly move out, bringing lighter rainfall, but any showers will still be capable of producing heavy rainfall. High temperatures should be slightly warmer than today, reaching the lower to mid 80s with a few upper 80s.

Late Week: Heat, Humidity Return

As mentioned yesterday, hot and humid conditions should return by late this week. As there should be temporarily drier conditions (though an isolated shower or storm can’t be ruled out on Friday), temperatures should rise into the lower to mid 90s on Thursday, and the mid to upper 90s on Friday away from the coast, which combined with dew points in the lower to mid 70s, should lead to the heat index reaching the 100s.

Next Weekend And Beyond: More Storms, But Heat Continues

The next cold front should affect the area on Saturday. This front should bring a risk of severe weather for western New York and Pennsylvania for Friday, however this risk should be smaller by the time that it gets here. The wind shear and lapse rates are more supportive than they were for today, however they are not too supportive, leading to at least a 5-10% risk of severe storms. The main threat with these storms again should be heavy rainfall. Stay tuned for more details on this next rain potential.

The storms move out by Sunday, however the cold front, like most cold fronts so far this summer, will fail to bring much relief from the heat. There should be less humidity, however the temperatures will stay just as hot, in the upper 80s to lower 90s, and may warm up for early next week.
