TUESDAY SUNRISE: 5:40 AM

TUESDAY SUNSET: 8:45 PM

High pressure the main weather-maker through Tuesday. Mainly clear Tuesday night with light winds and patchy valley fog for late. Lows Tuesday night in the mid to upper 50s.

High pressure moves east through Wednesday. Southwesterly winds increasing the heat and moisture over the region. Increasing clouds into the afternoon with an isolated shower and thunderstorm possible through late day and overnight. Best chances for rainfall staying in western New York. Warm and muggy Wednesday with highs into the mid to upper 80s and dew point temperatures approaching 70 degrees. Lows Wednesday night in the mid to upper 60s and another round of fog possible.

Frontal system increases our chances for showers and thunderstorms Thursday. Rainfall possible in the morning as a warm front moves through the region, but best timing will be in the late day as the cold front moves into the region. Plenty of moisture available for heavy rainfall, but will be fast moving so that should limit any flooding concerns. Storm Prediction Center keeps the Twin Tiers in a Marginal Risk (1 out 5, 1 being the lowest) for strong to severe thunderstorm development. Gusty winds and hail are possible with any strong to severe thunderstorms that may develop. Highs Thursday into the low to mid 80s. Second cold front passes Friday which may bring a lingering shower and thunderstorm. Highs Friday close to 80 degrees. Saturday brings dry weather, then a slight chance for showers Sunday. Highs this weekend into the 80s.
