I hope you have enjoyed the past few days! It has felt more like the end of July / beginning of August than the end of September. On Saturday the high temperature at Rochester International Airport was 80º which is the high temperature we typically feel on July 30th.
In regards to temperature, the month of September can be broken into four distinct weeks. The first week was above average with one of the warmest days of the year (85º on the 4th). The second week was way below average with only a high of 51º on the 12th. The third week was typical with highs bouncing just above and just below average. And the final week of the month is on track to stay way above average.
If you are looking forward to more fall like temperatures, then I have some good news for you. A strong storm system which has been battering the west coast the past few days has its sights set on the Midwest.
There are a few days to figure out the timing of this storm but it looks like we start to see impacts Tuesday night lasting through Friday.
Not only does this storm bring a good chunk of rain and the possibility of stronger thunderstorms, but it also brings a big cool down. The first few days of October are forecast in the middle to lower 60s which puts them right at or just below average.
Beyond next weekend, a cooling trend may continue with the Climate Prediction Center showing the possibility for below average temperatures as we move into the middle of October.
