Regardless of snow totals, Friday and Friday night will be mighty cold. Highs in the mid to upper 20s with 10-15 mph winds frequently gusting near 30. Will feel (and hopefully look) like winter finally.
Ah, we hardy ever fly out of BWI with checked baggage. We usually are home around 1:45. We park in the onsite garage almost always, sometimes we use Fast Park and Relax but I hate shuttles, even though theirs are fast and take you right to your car.
