Discussion

It’ll be colder today in the Philly metro region on the back side of a frontal passage and sun will give way to late day clouds as low pressure organizes over the Upper Midwest. A warm front will extend well to the east of the low pressure system and it’ll push in our direction later tonight spreading rain into the area that will last through much of the day on Friday. Rain has been a rare commodity in the Mid-Atlantic region during the month of January which has been much drier-than-normal in the local area with a deficit of 2.43 inches. At the onset of the rainfall late tonight, it may be just cold enough for the rain to freeze on some surfaces; especially, across the far northern and western suburbs. Temperatures during the day on Friday will climb to well above freezing levels (into the upper 40’s) assuring “plain” rain as we close out the work week, and then it turns moderately cold again to begin the weekend.
