Detailed Discussion

High pressure overhead late today will remain nearly stationary overnight, then drift east on Saturday.  It’ll maintain dry air over us tonight and tomorrow morning, so we’re in for another cool night tonight, still near or below freezing in the mountainous hollows, especially from the Green Mountains east, but holding in the 30s to near 40 in the Champlain and St. Lawrence Valleys, where a southerly breeze develops.

With the freshening southerly breeze, the temperature will warm to the low and mid 60s region-wide on Saturday, not far from normal for the last weekend of April.

During the day Saturday, morning sunshine will begin fading behind increasing afternoon clouds, especially over eastern New York.  This is part of the next weather system, a storm tracking northeast through the Great Lakes. The push of warmer air should establish a warm front in advance, lifting through here Saturday night with a good chance of showers. That will introduce warmer and considerably moister to our region for Sunday, with 60s to near 70.

The storm center to our west will track northward through western  Quebec, with a hesitant approach of a cold front from the northwest Sunday night, enough to bring a renewed chance of showers to northern areas at that time.  High pressure will build through Quebec Monday, and potentially nose south through the Canadian Maritimes Monday night and Tuesday, while a series of storms track northeast through the Great Lakes to our west. This could lead to the formation of a quasi-stationary front through eastern parts of the region, which keeps the potential for some showers in the forecast each day through the middle of next week. Milder temperatures will prevail from the Green Mountains west, but it could turn cooler to the east, especially through NH.

Farm & Garden

Rainfall Forecast:
No precipitation expected  through Saturday, except a rising chance of showers late Saturday in the St. Lawrence Valley, spreading east Saturday night, and becoming likely through the Adirondacks and Rt. 2 north, tapering off on Sunday, and just scattered south, mainly through Sunday morning. Amounts will be light. A few localized or stray showers Monday, again with light amounts.

Drying Conditions:
Good to excellent drying expected Saturday from the Champlain Valley east, with minimum relative humidity near 30 percent, becoming fair in NY with showers developing later in the afternoon, as minimum relative humidity near 35 percent rises. Fair to locally poor drying Sunday with scattered showers, and minimum relative humidity near 50 percent. Fair to good drying on Monday, with isolated showers. Fair to poor drying Tuesday, with showers likely.

Frost:
Not as cold tonight, with mid 20s to mid 30s, and then well above freezing through the weekend into the first half of next week.
