Detailed Discussion

A decaying occlusion to our west is responsible for the clouds this morning.  Isolated to scattered sprinkles and light showers have made it into the Adirondacks, St. Lawrence Valley, and as far east as north-central Vermont through the Eastern Townships but are dissipating as they outrun moisture and surface convergence.  Cloud cover should thin enough to let some filtered sun through today and the temperature should climb into the 60s to about 70 once again–warmest west of the Green Mountains.  East of the Greens, there’s enough of a maritime influence to hold the temperature down a few degrees.   The surface frontal boundary itself will dissipate before reaching here:  the ridge over us is resilient and should hold through this evening. 

Another cold front now over the western Great Lakes will make a run at the region tomorrow, and it should have enough oomph to break down the ridge.  A plume of moisture will be advected ahead of it into the region and will support widespread showers beginning tomorrow morning over eastern New York, then spreading across Vermont, New Hampshire and adjacent parts of southern Quebec and Massachusetts during the midday and afternoon.  A layer of unstable air aloft appears likely to get into eastern New York and may support a few rumbles of thunder as well.  Near the surface, an increasing southerly to south-southeasterly flow off the Atlantic will pull maritime air inland, holding the temperature down:  50s should do it for highs in almost all communities. 

The moist axis will exit east Sunday night, and widespread showers will end.  The front will ease through by midday Monday, with scattered light showers along its axis, then high pressure and dry air will follow through Tuesday.  The next chance for showers thereafter will be Wednesday.
