Detailed Discussion

Yesterdays’ showers might have been hit-or-miss, and only a bit of localized snow was noted, but everyone is feeling the effects of the sharp cold front responsible this morning, thanks to gusty northwest winds in the wake of the front, sending a late-season chill into the region, with reading in the 20s, even some teens in colder spots north, both higher terrain, but in some valleys where the winds died down. It means a hard frost and freeze to start the day, though it also comes with blue skies, part of a dome of cold high pressure, located over the eastern Great Lakes, north to western Quebec this morning. This high gradually works east during the day today, accompanied by some very dry air, which also means lots of sunshine. As the high edges closer, we can expect a relatively gentle northwest wind, though temperatures, in spite of the sun, will remain in the 40s north, upper 40s to 50s south, about 10 to 15 degrees below normal. The high then crests over us tonight into Friday morning, giving us another cold, frosty start, in the 20s and some teens. Then, the high drifts to the east Friday, taking the coldest air with it, which allows the temperature roller coaster to climb back to the 50s, close to 60 in the warmer valleys tomorrow afternoon. The high continues to drift east Saturday, close enough for a cool night Friday night, still near or below freezing, 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 on Saturday, thermometers will warm to the low and mid 60s, not far from normal for the last weekend of April. During the day Saturday, morning sunshine starts to fade behind increasing afternoon clouds, 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 steers even warmer air in our direction for Sunday, with some 60s to low 70s, along with some localized, scattered showers. The warmth represents a change in the weather pattern, initially steering some storms to our west through the Great Lakes, sending thermometers to their warmest levels since last October, some 70s, though a few episodes of showers are possible.

Farm & Garden

Rainfall Forecast:
No precipitation expected today 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:
Excellent drying conditions today and Friday, with minimum relative humidities near 25 percent. Good to excellent drying expected Saturday from the Champlain Valley east, with minimum relative humidities near 30 percent, becoming fair in NY with showers developing later in the afternoon, as minimum relative humidities near 35 percent rise. Fair to locally poor drying Sunday with scattered showers possible. Fair to good drying on Monday, with a chance of a shower or two.

Frost:
Frost or below freezing temperatures tonight. Not as cold Friday night, with mid 20s to mid 30s, and then well above freezing through the weekend.
