and internationally. so evacuations were ordered, not just of the police station, but like you said, the mcdonald's down the street and the walmart. i am told the grenade was deemed safe and it was by a military ordinance disposal technician. earlier today i asked police to give me an answer what did someone do if they find something like this inside their home? they say you should not bring it to a police station. you should go ahead and call police and what you have found inside your home and they'll take care of that for you. meagan, back to you. >> darcy spencer reporting for us in the northwest. thank you, darcy. >> now to the latest in the san bernardino shootings. federal investigators are looking into whether tashfeen malik radicalized her husband and if she was the driving force behind the rampage. the pakistani-born malik pledged allegiance to the islamic state on facebook about the same time she and her husband syed farook

of 36 degrees, but by recess we're in the low 50s and dismissal will be nice with the temperature around 55 degrees and that will be our high for the day. with future weather, i'm showing you at 5:00 in the evening and for most of us, whether or not it's impacting the commute at all. there is even as close as warrenton although future weather is keeping you dry and even isolated showers and sprinkles and that's really it. we're seeing more clouds moving in tomorrow evening and if you're headed to the redskins game with the 8:30 kickoff that's a good thing because they won't act as a blanket. 8:00, around 48 degrees and by 10:00 p.m. the temperature at 46 at midnight and keeping it dry for the redskins game and not trying to continue for the remainder of your workweek. on tuesday, mostly sunny. a high of 52 and a mix of clouds and sun and a high of 54. notice the high temperature, 59
