A cold front passed through the area last night, offering a tiny bit of relief from the heat and humidity of the past few days. There is still a heat advisory in effect for the city, and this afternoon is likely to be the fifth straight day above 90, but unlike over the weekend the heat index should stay under 100 degrees.
The cold front is stalled out just south of Long Island today. It will return as a warm front tomorrow as the storm that has caused the incredible rainfall and flooding in Louisiana moves toward the Great Lakes. The humidity will return and we are likely to see showers and thunderstorms on Tuesday, especially in the late afternoon. Tomorrow's high will be in the upper 80s but could again reach 90 if we get enough sun.
The front is going to change directions again on Wednesday as the storm moves away from the Great Lakes and passes well to the north of us. Since it is the same front as last night we can expect Wednesday's weather to be pretty close to today's, so look for a mix of sun and clouds and a high near 90. We should see lower humidity later in the week but Thursday and Friday are still expected to be warm with highs in the upper 80s both days.
