There were and are some ice jams around the region, and that state of affairs should continue the next few days as the weather stays warm.
So far, flooding from the ice jams has been pretty minor.
The worst ones so far is are along the Mad River in Waitsfield and Moretown.. Water behind the jam in Waitsfield rose several feet in minutes.
The ice also re-routed the Mad River through a parking lot in town. So far, there's been no major damage and the jam is of course being monitored.
At last report, there was another ice jam along the Mad River downstream in Moretown. If the Waitsfield jam breaks abruptly, the added surge of water and ice could cause some flooding in Moretown.
An ice jam broke up along the Missisquoi River around Richford which sent a surge downstream. That flooded and closed the end of Boston Post Road in Enosburg. That spot is a perennial lowland flooding area.
Also, a mudslide closed part of National Guard Road in South Burlington Saturday, but the road has since reopened.
Warm weather today and tomorrow will keep thawing the rivers, and more ice jams are a good possibility, which could lead to scattered instances of flooding. Otherwise, the snow is melting rapidly and rivers have risen. The snow depth near the top of Mount Mansfield went from 81 inches Friday to 67 inches Sunday, so you can see it's disappearing fast.
Other than the ice jams, no flooding is expected today and tomorrow, though water levels will be up somewhat. We'll have to watch for at least minor flooding Wednesday, depending on what a storm does then. More on that in a minute.
MARCH WARMTH
Temperatures got into the mid-50s in most Vermont valleys Sunday, which was a little above forecast. That makes me wonder if today and tomorrow might get a little warmer than forecast, too. Rather than 50s, I think many valleys might reach the low 60s today.
There might be a couple record highs here and there in and near Vermont today and/or tomorrow, but most places will fall short of those records. The record high today in Burlington is 70 degrees, which is higher than most records this time of year. It won't get that warm today. Burlington has a slim shot of reaching tomorrow's record high of 63 degrees.
Even if there are no record highs, the high temperatures over the next two days are normal for late April, so enjoy it while you can.
Today will be breezy, especially in the Champlain Valley. A warm front passing by to our north was creating showers near and west of Montreal, but the only effect we'll have in Vermont is a few clouds.
It still looks as if tomorrow might be a couple degrees cooler than today in the north, especially in the northern Champlain Valley, but it will still get into the 50s there. Elsewhere, it looks like more low to even mid 60s, with lighter winds and sunshine.
Which leads us to what is still our mystery storm for Wednesday
WEDNESDAY QUESTIONS
The computer models have gotten their act together a little bit more with the projected path of a storm and cold front Wednesday and Thursday. The storm should pass close to or over northwest Vermont
The trouble is there will be a very tight temperature range from one side of the storm to the other. Just to its northwest, it could be cold enough for some freezing rain. Just the storm's southeast, it'll be near 60 degrees.
At this point, it looks like southern Vermont is in for some rain, with only a little snow at the tail end Thursday after the cold front goes through.
Central and northern Vermont, especially the northern Champlain Valley, are still solidly in question mark territory. These areas could still end up experiencing just rain until the very end when there would be a brief changeover to snow before everything ends.
Or, the storm could feature partly or mostly mixed precipitation. I'm hoping we know more tomorrow.
The rain, especially if it's still warm, could produce some river flooding Wednesday and Wednesday night. So whatever happens, there's going to be some hazard to deal with.
BEYOND WEDNESDAY
Starting Thursday, the warm weather will disappear, and not come back for a long time. There might be a warmish day thrown in here and there over the next two weeks starting Thursday, but most days will be at least seasonably chilly.
It'll be an active pattern, too. A small storm looks to come through Friday night and Saturday with some snow, maybe mixed with a little rain. Then, a larger storm is then possible next Sunday and Momday.
Signals for unusual warmth, which could result in localized record highs on Monday and Tuesday, continue. On Monday the warmth looks pronounced across our area, and then primarily in central and southern portions of Vermont and the Adirondacks on Tuesday as slightly cooler air filters in from the north. As far as actual temperature forecasts, will note there may be too much of a bias correction with the cold conditions we`ve had over the last couple of months. Some of the statistical guidance shows more widespread low to mid 60 high temperatures than the current forecast indicates for tomorrow; coupled with some of the dynamical models, greatest confidence in these warmest conditions are in the southern portions of the Champlain Valley and Upper Valley in Vermont.
