did find enough problems that they decided in december to start inspecting the bridge every six months instead of every year. and as you heard in tracee's package, a spokesman for the maryland state highway administration told us the bridge is safe and the chunk that fell is considered superficial and that it didn't come from a part of the bridge that would cause it to fail or fall down. he added only 3% of the agency's bridges are considered structurally deficient claiming that's the lowest percentage for the, quote, entire eastern half of the united states. tisha thompson, news4 iteam. a plea deal could be in the works for a local rabbi charged with voyeurism. pat lawson muse is here with details. >> jim, rabbi bernard fand elle is accused of secretly recording women in georgetown. he was a rabbi at the synagogue for 25 years. prosecutors are meeting with the alleged victims tonight to

just cloud cover around the area. we're not starting off bad at all tomorrow morning. it should be okay. it's during the afternoon and right around 3:00 we start to see that area of low pressure move to our north. that's the cold front that comes through. some shower activity maybe some snow shower activity right around the 2:00, 3:00 4:00 hours. and then it just brings in the cold. boy, by tomorrow night at 11:00 you will feel the difference. the brutal arctic cold is coming. nice temperatures today but tomorrow here comes the cold air. it will be here for friday. that's cold. but the really cold air comes in" after saturday into saturday night and sunday as another shot of arctic air begins to make its way in here. let's talk about that. first off tomorrow high temperature of 40 degrees but falling temperatures during the day, a low of 16 on friday morning. many of you will wake up to windchills close to zero on friday morning with the temperature near 28 for a high. then a better chance for snow on saturday, may accumulate in some areas but this is not going to

be much snow. the bigger story once again is the wind and temperatures. 21 degrees on sunday with a wind gusting close to 45 to potentially 50 miles per hour. this is something we really have to watch out for. right now we're forecasting windchills to be between minus 10 and zero around 8:00 a.m., 5 below to 5 above around noon and 5 below to 5 above around 4:00. an extremely cold day with the wind gusts the windchill could be 15 or 20 below zero. that's the kind of cold air. we have it a little better on monday, but a high of only 28 and not far from a record low temperature on monday morning. guys, get ready. winter is really going to grasp hard. >> yes, it is. there is a recall alert now for a product that's supposed to protect you in case of an emergency. the consumer products safety commission says certain comebos of the carbon monoxide/smoke dedektors are under recall because they can fail to detect co gas. it affects the i-4 series of the
