Forecast discussion: Despite the calendar saying mid-September, it felt more like August in Providence on Wednesday. A warm front helped bring tropical air back to the capital city, as temperatures at T.F. Green Airport in Warwick reached 91 degrees. We will see another warm day, before autumn takes over this weekend.
Right now, we are waiting for a cold front passing through Michigan. This front is helping to create thunderstorms over eastern New York. The front will slowly move towards Southern New England Thursday, so we will see limited sunshine during the morning and afternoon. I am expecting heavier showers, rain, and maybe some isolated thunderstorms for tomorrow night into early Friday morning, as the front moves through the region. This might create some wet weather for the Patriots in Foxboro tomorrow night during their home opener.
By Friday afternoon, the cold front will be offshore, and any leftover precipitation will come to an end. There may be some localized flooding, especially in areas where there is street flooding, during Friday morning, as some areas could see up to 2 inches of rainfall. Otherwise, we will see temperatures in the middle 70’s.
Through the weekend and early next week, high temperatures will only be in the middle 60’s to lower 70’s. This is due to cooler air coming down from Canada. Overnight lows will be cool, with temperatures in the upper 40’s to lower 50’s. I am not expecting any precipitation at this time, but we will see some increasing clouds next Wednesday night from an approaching frontal boundary.
Meanwhile, the tropics continue to become more active. As of 5 p.m. EDT, Tropical Storm Gabrielle was centered at 32.8N 66.4W, or about 100 miles west-northwest of Bermuda. Maximum sustained winds are at 40 mph, and is moving west-northwest at 5 mph. Gabrielle will pose no threat to the east coast, as the system will begin to turn towards the northeast by Thursday night, and be picked up by the departing c
Hurricane Humberto is located at 18N 29W as of 5 p.m., or 360 miles west-northwest of the southernmost Cape Verde Islands. Maximum sustained winds are at 85 mph, and is moving north-northwest at 12 mph. Humberto will run into a ridge of high pressure, and begin to track more to the west by Friday afternoon. Due to cooler ocean temperatures and wind shear, Humberto will weaken to a Tropical Storm within 60 hours.
Meanwhile, there is now a third area of interest. This area is over the Yucatan Peninsula. The circulation is expected to enter the Bay of Campeche tomorrow, setting up to be over warm water. This will help the low become a tropical system within the next 5 days, and could become a tropical over the next 48 hours if the low can remain staying over water and not moving back over land.
