day. 61 in ft. belvoir. weather related slowdowns nothing to worry about today and tomorrow. back to work, school and reality, nothing to worry about there. a chance for showers coming in wednesday afternoon. could cause some brief slowdowns late in the day on wednesday. but that's days away. hour by hour, temperatures in the mid to upper 60s by 1:00. 88 at 5:00 p.m. today. so it will be sunny and hot, more humid than it's been the last couple of days as well. 86 in bowie. 90 downtown on the national mall. 88 in fairfax and 86 the high in gaithersburg today. future weather, just sunny and
