ITHACA, NY – A summer-like start to the week it will feel more like March by mid-week as a complex storm system sets lingers over the region for a few days, drawing down large amounts of cold Canadian air. It’s nothing too serious, but after Monday, you’ll want to hold off on the outdoor activities until late in the week.
Like, totally, the 80s are making a comeback (at least for some locations west of I-81). There may be an isolated shower or thunderstorm today, but nothing strong. Much cooler weather returns for mid-to-late week. #pawx #nywx pic.twitter.com/TFN0dIj7Fy

Your Weekly Weather
It’s a warm spring Sunday in Ithaca thanks to a surge of warm air ahead of a storm system over the Upper Midwest. Interestingly, the surge of warm air is running up against the “backdoor” cold front that moved west into Eastern New York, resulting temperatures from New York City and Albany in the 50s and lower 60s, while from about Syracuse westward temperatures are in the mid 70s to mid 80s.
With the frontal frontier of the low lying west, the rest of Sunday will be quiet, though there is sufficient moisture and instability in the air for isolated shower or thunderstorms across the Finger Lakes and Southern Tier. Temperatures have topped out in the low 80s around Tompkins County. There will be some increasing clouds after sunset but it should remain dry overnight, with mild lows in the low 50s.
Monday will start to push into Upstate New York Monday afternoon, with the first rain showers arriving in Tompkins County by late afternoon or early evening. With high pressure over Southern New England, the front will slow down, it is expected to be cloudy and rainy Monday night, with periods of light to moderate rain, perhaps with some thunderstorms between midnight and sunrise, with lows in the low 50s. New rainfall
A reinforcing low over the Western Great Lakes should help shunt the front eastward Tuesday, and that should end the steadier rain, though showers will persist through the afternoon. Skies will remain mostly cloudy to overcast, and it will be very cooler, with highs in the low 60s. That reinforcing low should move in Tuesday night, which will keep the cloud cover around and spur the redevelopment of scattered rain showers after midnight, and maybe a few snow showers at the higher elevations until morning. Lows will be in the mid 30s.
Wednesday just ends up being a raw, unforgiving day as the coastal zone system is developing, and across large quantities of cold on its backside of its counterclockwise circulation. That northerly flow will trigger some lake-enhanced rain and snow showers, and it will be much colder than normal, with mostly cloudy skies and highs only in the mid 40s. New rainfall Wednesday night will see drier conditions combined with low pressure system moves, and it will be mostly cloudy overnight with lows in the low 30s.
Thursday offers some improvement in conditions as low as the east, but it can be strengthened, and it will allow a cold funnel into Upstate New York. Skies will turn from partly cloudy to late in the day as high pressure moves in the northwest. However, a stiff northerly wind will keep temperatures confined to the upper 40s for highs. Thursday night will see the southeast slacken, with partly cloudy skies and a low in the mid 30s.
Friday is marginally better as high pressure moves overhead. There will be mostly sunny skies with a high in the mid 50s. Friday night will be partly cloudy and dry with lows in the mid 30s.
A storm system over the Midwest will struggle to press east next weekend, so it’s looking pretty dry and maybe a touch on the cool side for now, with partly cloudy skies and highs in the upper 50s and low 60s.
Looking into the first week of May, the pattern generally calls for persistent jet stream troughs over the Pacific Northwest and Eastern Great Lakes, with colder than normal temperatures likely. Gulf Moisture flows up the Mississippi River Valley, but locally precipitation should be near-normal.
