Before most people wake up early Thursday, the temperature at Buffalo could drop into the 30s.
In other areas further inland and in the Southern Tier it could dip even further - maybe below freezing in some areas.
On May 14.
Updated forecasts show the temperature at Buffalo bottoming out at about 38 degrees just before dawn. In places as close as the Southtowns forecasts show the temperature will drop to freezing.
The all-time record low for the date was set in 1878 when it was 33 degrees at Buffalo.
The quick blast of cold isn't good for your garden or outside plants.
That's why there's a freeze warning in effect from midnight to 8 a.m. Thursday for southern Erie, Wyoming and all of the local Southern Tier counties.
"A few hours of below freezing temperatures away from the lakes will result in damage to tender vegetation," the weather service warning stated.
Outdoor plants will be threatened and the weather service recommends that potted plants "normally left outdoors should be covered or brought inside away from the cold" in those areas.
Meanwhile, for the northern half of Erie County as well as Niagara, Orleans and Genesee counties, a frost advisory is posted.
That means that, while the thermometer won't necessarily drop as low as places in the warning areas, there's still a threat of damage and precautions should be made "to protect tender vegetation."
To add insult to injury, the quick blast of cold comes following a five-day streak of temperatures in the 80s that graced Buffalo between last Thursday and Monday.
The unseasonably warm weather led to a quick greening of the landscape and emergence of many flowering trees, shrubs and leafy plants.
