Here’s the good news: There’s no need to move your vehicle for street sweeping this week, according to the Department of Public Works. Here’s the bad: The program is cancelled because of the predicted snow storm.

Yes, according to the downers at the National Weather Service, there’s a 90 percent chance of precipitation Tuesday, with one to two inches of snow predicted to fall after 9 a.m. From the latest forecast discussion:

Snow will break out across lwx Tuesday morning and continue through the day. Mesoscale banding is expected…but transient. therefore a high pop with lower qpf approach is still relevant. The column will be subfreezing with the sfc layer temp determining snow or rain. The probability of rain mixing in increases east from I-95 with essentially all snow west. Precip onset looks to be around sunrise Tuesday for areas east of the Blue Ridge with the bulk of precip during the day. Snow accumulation should be limited to grassy surfaces with slush on roadways during the heaviest snow due to the bulk of precip occurring during daylight hours and sly flow. Winter weather advisories for snow are likely for most of the area due to snow during the morning (and some of the evening) commute which only requires likely probabilities for one inch in the OPM commuting area. (Two inches elsewhere).

The reason that DPW can’t sweep the streets when this happens? “Sweepers empty the debris they remove from the streets into dump trucks, which also are used in the snow program to spread salt during snow storms.”
