Flood Watch Cancelled For The Entire Region

Local Report...
   Significant Rainfall Coming To An End; Flood Threat Has Diminished...

DISCUSSION
     I have decided to drop the flood watch for the rest of Vermont. Rivers are already starting to show signs of cresting. There may be some additional rises, but rivers should not rise above flood stage. Smaller creeks, streams, and brooks could rise slightly out of their banks, resulting in some minor field, and low land flooding, but nothing that's a threat to life or property, and nothing that will be widespread.

     Current radar trends indicate steady rain has moved out of the region, and well into Maine. The upper level low still situated over the State of New York, will continue to slowly drift north, while the 985mb surface low pressure currently north of Boston, will drift north as well. Both areas of low pressure will pretty much come together and become the same broad area of low pressure, and meander around north of the international border at least into Wednesday, before weakening enough to hopefully stop having an influence on our weather. Additional valley rain showers, and mountain snow and/ or rain showers will continue well into Wednesday. No real significant accumulation is likely. At best a quarter inch of rain could accumulate, with locally higher amounts in some areas, but nothing that is going to cause any type of hydrological problems.

     As far as snow goes, by Wednesday we could see a total of 1-3 inches with locally higher amounts. The Northern Adirondacks would be the most likely to see higher amounts, as lake effect precipitation off lake Ontario will slightly enhance any snow totals. These accumulations will be confined mainly to elevations above 1000 feet, with only a trace to perhaps an inch below 1000 feet. With that said though, portions of the Tug Hill Plateau look to get hammered with snow once again. The tug hill region is under a Lake Effect Snow Warning, where snow totals could range from 10-18 inches!! Lower elevations such as Watertown, Adams, and Parish will likely have significantly less snow, ranging from 4-8 inches. Some areas along the immediate lake Ontario shore, will likely see only a trace of snow accumulation. One impressive fact about this entire situation is if Barnes Corners pulls off another 10-18 inches, then they will have received 28-36 inches of snow, just in the past two or three days. That's impressive for being in the month of April, but not totally unheard of. Now I love snow, but 2-3 feet of fresh snow on the ground in April!! Yikes!!

     Have yourself a goodnight everyone!
