Detailed Discussion

High pressure is starting to drift just to our east as the weekend begins.  It’ll maintain dry air over us through midday, so we’re in for a bright sunny morning before weather conditions slowly start to deteriorate this afternoon over western sections.  Eastern sections should enjoy a splendid day, albeit with some high, thin cirrus starting to filter the sun this afternoon.  With a freshening southerly breeze, the temperature will warm to the low and mid 60s region-wide today, not far from normal for the last weekend of April.

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 tonight with a good chance of showers. That will introduce warmer and considerably moister air to our region for Sunday, with highs 60s to near 70 and dew points near 60.

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 the region, which would keep the potential for some showers in the forecast each day through the middle of next week.  The best chance for showers would be Tuesday and Tuesday night, with upper ridging shutting off widespread showers for Wednesday although residual low-level moisture could linger in the vicinity of the front.

Farm & Garden

Rainfall Forecast:
No precipitation expected  through today, except a rising chance of showers towards evening in the St. Lawrence Valley.  Showers likely overnight especially through the Adirondacks and Rt. 2 north, tapering off on Sunday.  More scattered coverage south, mainly through Sunday morning. Amounts will be generally be a quarter inch or less through 8 a.m. Sunday.
From 8 a.m. Sunday through 8 a.m. Monday, scattered showers and possible isolated thunderstorms will bring highly variable amounts.  Generally .25″ or less, but spot amounts up to .75″ are possible in any places hit by a thunderstorm, or multiple showers.  The best chance for higher amounts will be over southern Quebec, far northern New York, far northern Vermont and northern New Hampshire.
Widely scattered showers Monday, again with light amounts.  A more general soaking showery rain is likely on Tuesday.

Drying Conditions:
Good to excellent drying today from the Champlain Valley east, with minimum relative humidity near 30 percent, becoming fair late in the day across NY with showers developing towards evening as minimum relative humidity near 35 percent there 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. Poor drying Tuesday, with showers likely.

Frost:
Overnight temperatures well above freezing through the rest of the weekend and much of the upcoming week.
