JAMESTOWN – Some of the hottest and stickiest air so far this summer is on its way to Western New York late this week with tropical showers on Wednesday with the leftovers of Tropical Storm Barry.
Through the afternoon today, scattered showers and storms will develop from west to east across the Southern Tier. This will not be an all-day rain with some limited peaks of sunshine at times as well. Temps will range from 78 on the highest hills to 86 along the lower elevations. The humidity will also be a factor with dew points nearing that oppressive level once again.
The remnant Low of Barry is currently located south of St. Louis and will pass south of our region over there next 24 to 48 hours, bringing with it tropical rain and thunderstorms to the area late tonight through Thursday.
The primary noticeable difference between traditional summertime rain and tropical rain is how big the rain drops are. Tropical rain tends of have smaller and less reflective raindrops which allows for a much larger output of precipitation and yields much higher rainfall rates.
While it won’t be raining all the time on Wednesday, when it does rain, it could be a downpour with torrential rainfall. We’re likely looking at totals pushing over one inch on Wednesday alone across the region. Not only could the very heat rain pose a flash flooding risk, but poor drainage flooding is possible as well.
Behind Barry comes very hot and very sultry air for the reminder of the week. Actual air temperatures will approach 90 with heat indices likely in the 94 to 98-degree range Friday and Saturday. The National Weather Service may opt to issue Heat Advisories for parts of the region for this period.
Overnight lows will only dip into thew lower to mid 70’s making for very uncomfortable sleeping weather if you do not have air conditioning.
