Discussion

Two separate low pressure systems will impact the eastern US over the next few days with the second system being the stronger one and having more of an impact on the DC, Philly, NYC corridor. Light rain is likely today from the first system and a wintry mix cannot be ruled out at the onset in the far northern and western suburbs. The second system will track up through the Ohio Valley at mid-week and rain will be the result here in the I-95 corridor and it’ll fall heavily at times from later tomorrow into early Thursday and a thunderstorm cannot be ruled out. Cold air returns for the late week time period following that second storm system and winds will become quite strong on Thursday and Friday. Looking ahead, it looks like this will be the beginning of an overall colder-than-normal stretch of weather that could last right into mid-March.
