Across the Twin Tiers to begin the work week we will be seeing some heavy rain move into the region. This will come after shower chances throughout the day on Sunday, which includes during the Wineglass Marathon. A warm front will push through overnight tonight and bring those chances for showers during the day Sunday. A cold front will push into and stall over the region for a bit Monday with heavy rain possible across the region. Because of this cold front stalling across the region, we will see a stream of moisture pumped into the area which will bring the rain. Totals over the next three days could total up over an inch of rain and close to 1.5" as some locations could push 2" of rain. Make sure you bring the rain coats and umbrellas for Sunday and Monday with this rain expected.
