7:00 AM | A surge in temperatures today, but a major cold shot arrives for the weekend and snow is not out of the question in nearby higher elevation locations and perhaps even into the big cities; Antares rocket launch postponed until early tonight

Discussion
There will be a surge in temperatures today ahead of an approaching cold front with highs well up in the 70’s up and down the I-95 corridor from DC-to-NYC. This warm up will be short-lived; however, as a cold frontal passage will begin a downward trend in temperatures for the second half of the week. A major cold shot will arrive on Saturday as deep upper-level troughing develops in the eastern US and this will lead to the formation of a storm near the Mid-Atlantic coastline. As a result, winds will howl on Saturday, high temperatures will be confined to way below normal levels in the 40's, and some precipitation is likely which can be in the form of snow in higher elevation locations just to the northwest of Route I-95 and perhaps even into the big cities from DC-to-NYC.
One other note, last night's Antares rocket launch at NASA/Wallops Island, VA was scrubbed due to a boat in the launch site area. The rescheduled time for the launch is 6:22PM early tonight. While clouds were not an issue last night in terms of viewing conditions around here, they will be a bit more of a concern early tonight.
