Our hot and humid airmass comes to an end as a cold front crosses WNY Friday afternoon. The main threat of rain arrives near noon along the Lake Erie shoreline. Thunderstorms develop ahead of the front with a slight risk to become severe with strong winds, heavy rain and a small chance for hail. From 2pm-5pm south and east of Buffalo, t-storms will fire up and another line between 6pm-9pm across the S.Tier. Rain cooled air arrives for the evening. Spotty showers remain overnight as much cooler air settles across WNY.
The last two weeks of May have been well above average, and the last few days have felt like we were in the midst of summer! Record breaking heat took Buffalo 20 degrees above average and a short two weeks prior to that temperatures we're well below average, just about 20 degrees with record cold and snow. This cold front takes the summer temps and drops them right into fall territory this weekend with highs in the 60s Saturday and even the 50s Sunday. S.Tier valleys on Sunday morning may approach the 30s!
In all, with the temperature swings through the month, May will go down just about average with June beginning below normal. Check out your 7 First Alert Forecast for the first week of June.
