suburban sanitary commission said four valves had to be located and shut down to stop the water. problems with water pressure disappeared once that was done. they issued a boil water advisory as a precaution. >> there are no issues with contamination in the system. however, what you lose pressure for an extended period of time it, can cause the possibility for contamination. that's why we need folks to boil their water until we lift the advisory. >> you have an aging system and every year, every couple of months or so we experience something like this. >> reporter: and now it's happened

collected somewhere around 16,000 gallons of that oil has been contained, but some of that oil did enter the river. >> reporter: we're told mineral oil is not considered toxic to humans, but wildlife

say by smugglers using the addresses of unsuspecting people. police say officers killed the dogs because they felt threatened. >> we've done over 100 hours of depositions to really understand what

put in place best practices and that to me is a big deal. >> reporter: the police never apologized for the way in which the raid was carried out. mayor calvo said the sheriff even called it a model

course just under a minute, if that is your cup of tea. >> i hope it is. that looks like it would be so dangerous. might be a thin spot. i'm sure they check it carefully, but don't try this at home. >> we were talking a little while ago we always say what a difference 24 hours makes. yesterday it was cold outside, but today it was bearable. >> tonight is not as cold and it's hard to believe tomorrow after today, can we really get to the mid-40s that fast and we can because of the south wind. >> okay. >> huge area of arctic high pressure, bitter cold is pushing off to the east and yes, we are going to ease this cold during the day tomorrow. wow, look at that shot with the steam going by. yes, it's definitely still cold out there tonight, but nowhere near where we descended to last night. let's take another look at some of those temperatures dropping to the 17 degrees at reagan national, manassas and camp springs down to 5 and 8 degrees. of course, prince george's county is where we had that water main break today. leesburg dropped to 7, fort belvoir 8, dulles 6. we will be at least 15, if not 20 degrees warmer for some of those places tonight. staying in 20s, maybe low 20s for a few of you, but d.c. came up 1 degree at 11:00, dulles 28 as is manassas. toward annapolis you are 29, leonardtown 28 degreesful your forecast tonight, a few clouds -- degrees. your forecast tonight, a few clouds and south wind, low 20s, maybe mid-20s. tomorrow sunshine, dry all take long and we get up to about 46 degrees -- day long and we get up to about 46 degrees. i think tomorrow will be fantastic, giving you a hope that spring is coming. 31 at 8:00, by noon 42 degrees and 5:00 we begin to see the clouds increasing, 43 degrees. tomorrow night is an important night because we'll be watching moisture from the south heading in our direction and something interesting about that moisture i want to show you, certainly very cold in the northeast. rochester's high was 16 degrees, boston 13 while we were 32, but where our storm is forming is in the gulf of mexico and it was 71 degrees today in new orleans. what a contrast with little rock coming in at 44 degrees and dallas at 56. so there's definitely some warm air down here which will fuel up a pretty significant storm, but nor in greed yet we really needed for that -- another ingredient we need is for that high pressure to stay in place. we get our return flow and milder day out of it tomorrow. wednesday is not tear cold either. here -- terribly cold either. rain is changing to snow on wednesday because of this storm, but we have the usual questions this far out with a storm happening during the day wednesday and change over to snow wednesday night and that has to do with the placement of the area of low pressure, but in this particular case there's a second piece of energy behind the storm, the upper level energy that may be the thing that brings our snow and we'll have to watch temperatures. it could be in the upper 30s on wednesday. at 5 a.m. we begin to see our little bit of mix with the green representing rain. that's primarily south and east of 95 for much of the day, although now weapon got your rain/snow mix at -- we got your rain/snow mix at noon. then we have snow west of interstate 81, but as we go through the day we begin to see this changing back over and then moving out by about midnight or so to the eastern shore. how fast that moves out, where that area of low pressure is what that upper level feature is like will determine how much snow we may get out of this thing wednesday night, but it looks like wednesday at the very least will be messy and we'll give it some numbers tomorrow night when we're within our safe period to give you a good idea of what is going to be happening, but i would certainly highlight wednesday as a day that may feature trouble especially in the evening. thursday 38 degrees, any snow very early probably before the sun come up and quiet to end the week, 39 and 44 degrees. a couple of our teams, caps and wizards, were in a new york tell us if they night. were able to manifest their own destiny with that when he returns with sports.
