After the coldest morning of the autumn so far, temperatures will rebound 30 degrees or more to seasonable levels by Wednesday afternoon around Philadelphia.
Temperatures started the day Monday in the low-30s around the city, but in the northern and western suburbs dropped into the 20s.
The high is forecast to be in the low 60s on Wednesday, which is close to normal.
Prior to the arrival of another cool front with some rain on Thursday, temperatures will again peak in the 60s. Blustery and much cooler conditions will follow Thursday night and Friday.
The air behind that front is not as chilly as experienced to start this week. While it will get blustery behind the front on Friday, winds will not be quite as strong as which occurred last Friday. Still some flight delays are possible due to crosswinds on some of the runways.
Hurricane Matthew will take a northward turn this weekend, which will bring the storm along the Atlantic coast of the United States next week.
Hurricane Matthew will threaten the central and northern Caribbean with flooding rain, damaging winds and an inundating storm surge early next week.
It will feel like an extended winter for those living from the northern Plains to the eastern U.S., as cold and snowy conditions last longer than normal.
Persistent downpours will raise the flood risk in part of the mid-Atlantic into Friday night, while rain will spread over the balance of the northeastern United States into the weekend.
The final day of September will bring a rare lunar event that hasn’t occurred since March of 2014, a Black Moon.
The holiday weekend will start on an unsettled note, but the weather should improve by Day of German Unity celebrations on Monday.
