Storm ending, flooding still a concern

Even though the storm is pulling away, flooding will remain possible into Wednesday.

If you are interested in seeing snow totals so far, click here, its an interactive map that will let you move around and zoom in and out.  The amounts are impressive, especially in Upstate NY.

Also, if you want to see current river levels and forecasts, click here for Southern New England and here for Central and Northern New England.  You could click on the map to view the rivers levels and forecasts.

Flood Watches and Warnings are currently in effect for several locations in Southern New England.  Winter Storm Warnings continue into the middle of day.

Today:  Rain/snow/sleet comes to an end.  Temperatures remain steady or dropping slowing through the day.  Highs mid 20s north, mid 30s south.

Tonight:  Decreasing clouds, cold, lows near 0 north, teens to low 20s south.

Tomorrow:  Lots of sunshine, highs in the low to mid 40s south, upper 20s to low 30s north.

Wednesday:  Mostly sunny, highs upper 30s south, upper 20s to near 30 north.

Discussion:
The low pressure system that brought all the unsettled weather last night is continuing to affect New England, particularly in Central and Northern New England.  Snow and sleet is still falling in VT, NH and Maine.  The precipitation will hang on the longest in Maine, coming to an end late this afternoon.  Look for the snow to taper off in VT by Noon and mid afternoon in NH.  Additional accumulations are expected on the order of 3-6 inches in VT and NH, with another 6-10 inches in Maine with isolated higher amounts.

If you checked out the link above related to river forecasts, you would have seen that the flooding threat will continue into Wednesday.  It wasn't just the rain last night that is the main cause of flooding, it will be the runoff from melting snow that is still making it's way into the rivers of New England.  This is a slower process.  What the rain did do, is raise the river levels slightly and then when you add the runoff, the river levels are expected to shoot up higher.  So if you live near a river, keep a close eye on it and prepare as best you can.  Chances are, you've dealt with this before and know how to prepare.

As the storm pulls away tonight, the cloudiness will go with it and our skies will clear.  This will allow temperatures to fall off even more as well.  Places that received new snowfall will see the coldest overnight readings, some places getting down to near 0.  High pressure will start to build in tomorrow and will keep our weather quiet into the day on Thursday.  Temperatures will be a bit cooler during the middle of the week, then gradually warm up again.

The warm up begins ahead of another low pressure system that should pass off to our west late in the week.  This looks like it will be rain for nearly everyone this time, but this could obviously could change.  I'll have to keep an eye on this, but the storm we are currently getting looked like rain for everyone at first as well, that definitely wasn't the case.

That's all for now.  Post any questions you might have below in the comments section, I'll answer as I have time today.  Thanks for reading!
