Forecast discussion: After several weeks of heat and humidity, Providence felt more like late spring on Thursday, as temperatures only reached the upper 60’s in overcast skies. We also had precipitation during the afternoon, as T.F. Green Airport received about three quarters of an inch of rain. We will see the potential for more precipitation this evening into Friday afternoon.
The precipitation is due to a frontal boundary that moved offshore Wednesday afternoon. However, the boundary stalled, and is now actually turning back towards the north and west. A low pressure center formed off the Carolina coastline, and is helping to create some heavier precipitation for this evening. In lieu of some significant precipitation, the National Weather Service issued a Flash Flood Watch for all of Rhode Island from 10 p.m. EDT until noon on Friday. The front will slowly push back towards the Atlantic during the afternoon, and we should see partial sunshine before sunset.
As we move into the weekend, a high pressure system over eastern Canada will give us mostly sunny skies and warmer temperatures on Saturday. However, we will see some high to middle level clouds work over the region by Saturday night. A cold front in the Central Plains right now will bring more showers and thunderstorms by the early afternoon on Sunday. The front will remain inland through Monday afternoon, before drier air moves over New England Monday night.
We will see sunshine on Tuesday, with partial sunshine on Wednesday. A slow moving cold front will help create some showers by Wednesday evening. Right now, the computer models suggest a weak area of low pressure will move up into the front by Thursday, giving us more showers and periods of rain.
Meanwhile, Tropical Storm Dorian is located at 16.5N 37.8W, or about 1670 miles east of the northern Leeward Islands. Maximum sustained winds are at 60 mph with gusts of 75 mph, and is moving west-northwest at 18 mph. At this time, Dorian will continue on a west-northwest track over the next 5 days, while slowly intensifying as it moves into warmer waters. Dorian will become a strong Tropical Storm by Monday afternoon, with the chance of becoming a hurricane by early Tuesday morning. The system would be north of the Dominican Republic within 5 days.
