Hard to tell the difference between upstate New York and Reykjavík, Iceland, this weekend. #NYwx

Rainy Memorial Day weekend ahead. #NYwx

Happy unofficial start of summer, upstate New York! #NYwx

Today marked the first 90-degree day of the year from the Finger Lakes to the Mohawk Valley. Highs today included 91 in Syracuse, Ithaca and Elmira, 90 in Rome, 90 in Oneonta, 88 in Norwich and 87 in Binghamton. Tuesday will be similarly hot and a touch more humid. #NYwx

The weather pattern flips straight to summer starting today and lasting through midweek before a sharp cooldown late in the week ahead. That means we need to introduce the first notable heat risk of the season. On Tuesday, the National Weather Service’s HeatRisk product shows most of central New York faces a moderate risk (Level 2 out of 4) of excessive heat. Temperatures will climb into the upper 80s and lower 90s, with a bit of humidity making it feel even hotter than that as dew points reach the lower to mid-60s. As of now, Memorial Day weekend looks much cooler with highs in the 60s and a risk of showers. #NYwx

🥵 Summer is coming! #NYwx

At least it’s not snowing? #NYwx

Upper 20s with frost to start May. We’re stuck in a cooler-than-average pattern for the next few weeks. The good news is we’ve entered the longest days of the year with sunrises before 6 a.m. and sunsets after 8 p.m. for the next three and a half months. Sunrises won’t be after 6 a.m. again until about the second week of August, while sunsets wont be before 8 p.m. until about the third week of August. #NYwx

How would you feel about daytime highs in the mid- to upper 40s and overnight lows near freezing for the first weekend of May? What if snow showers and flurries were possible too? 😵 #NYwx

After 80-degree warmth just a few days ago, we’re now waking up to record-low temperatures across upstate New York. #NYwx

Monday. #NYwx

@Mell1960 At least it’s not the heavy snowstorm from this date 4 years ago when many of us woke up without power that didn’t come back on for days.

@WxBrianD I am NOT liking this weather...Has been snowing for the past hour. UNLIKE!

SUMMER FADES, SPRING RETURNS, THEN A FINAL TASTE OF WINTER Summer’s over for now as more springlike weather is expected today and Saturday with highs in the mid-60s to mid-70s. But we aren’t done with winter yet as much of central New York faces about 50-50 odds of measurable snow (at least 0.1 inches) between Sunday and Monday morning. The good news is we won’t be dealing with a power grid-crippling snowstorm like we did four years ago in late-April 2022 when tens of thousands lost power for multiple days. After a hard freeze Monday night, temperatures will reach the 60s again by the middle of next week. However, the general trend for the rest of April is cooler than average, so expect more days in the 50s and 60s rather than the 70s. You’ll want to hold off on planting any sensitive vegetation until Mother’s Day weekend. #NYwx

One more round of severe weather is expected this afternoon and evening across much of upstate New York. Damaging winds, large hail and a couple of tornadoes are all possible. Cooler, less humid weather returns Friday. #NYwx

Showers and thunderstorms are moving eastward into central New York this morning. Sunny breaks behind this initial round will push temperatures to near 80 degrees, fueling another round of storms late this afternoon into the evening, some of which could pack damaging wind gusts. The severe weather risk returns again tomorrow afternoon. #NYwx

After today’s mid-summerlike warmth, how would you feel about snow showers Sunday night into Monday morning, with wind chills in the 20s Monday afternoon and a hard freeze Monday night? #NYwx

Severe Thunderstorm Watch posted for central and upstate New York until 10 p.m. this evening. #NYwx

Severe thunderstorms are possible this afternoon and evening and again Wednesday afternoon and evening as high temperatures climb to 75-80 degrees across central New York. Damaging wind gusts are the primary threat, with hail and heavy downpours also possible. Most of central and upstate New York is under a Level 2 out of 5 risk of severe weather today, while Wednesday’s risk lowers to a Level 1 out of 5 and shifts to the southern tier. #NYwx
