here's a shot taking a look at the cathedral. look at the numbers. currently 32. winds out of the north at 12 miles an hour. again, the wind chill, that's where it's at. it's all coming from the wind and look at it, it's gusting to 20 miles an hour and these numbers will stay up there throughout the night tonight. winds gusting at 20 miles per hour, and the wind chills right now only in the teens in areas to the north. frederick right now a wind chill of 15 degrees, hagerstown even cooler than that, d.c. 23. we saw some snow showers coming through from time to time during the afternoon, but that was really about it. the winds continued, too, and the snow showers didn't amount to anything. but what this is doing, you can see the flow out of canada. this is bringing in the cold air. this is allowing that cold air to stabilize in our region and kind of sit here. notice the snow out towards iowa. this was the storm that was originally we were thinking a week ago could bring us some snow on sunday. this storm is s

coming up over the next few days. we'll show you that in just a second. 36 degrees. windy and just plain cold. wind chills in the 20s during the day tomorrow, and take a look at the future wind chill. tomorrow morning, how about 8 in gaithersburg, 14 in d.c., 11 in manassas to start off the day. again, we've got the rock and roll marathon tomorrow. 1: 00 in the afternoon, sunshine, only some teens across our region. that cold is entrenched. that storm we talked about for sunday is actually going to be off the coast of the southeast. we'll see another storm move down and actually pick it up and bring it back towards our area as a nor'easter. that brings us the snow along the i-95 corridor. the big question, and the big question with just about every nor'easter we see in our region, where is the rain/snow line. is it along i-95? is it just to the east of i-95? right now i think it would be just east, meaning more snow for the d.c.

something that we'll be watching closely. so a major nor'easter in the offing monday night into tuesday. a high impact event for everybody but still tracking the exact path. what else do we know? monday night into tuesday. yep, all models now have snow and significant snow at that. snow-covered roads as the cold air is already in place. rain/snow line definitely in play with this and this can and will change over the next couple of days. we still have a few days to watch it, but 49 on sunday, 41 on monday. wednesday a high of 31. that overnight low wednesday into thursday would be nd25 a if we get that low, it could be it for the cherry blossoms, unfortunately, until temperatures move back into the 40s. that is the coldest 10-day forecast we've had yet this winter. just amazing. >> you are expecting school delays? >> i think schools will be closed on tuesday and maybe wednesday. >> especially since they haven't used any of their snow
