Forecast discussion: A cold front passed through Boston earlier on Monday, bringing some scattered showers across the state. Some drier air arrived in the afternoon, as there was some sunshine for a brief period of time. As a high pressure ridge builds over the area this evening, skies will clear after midnight, and temperatures will fall into the middle 40’s.
As the high moves eastward, it will create a north-northeast wind, and temperatures will struggle to reach the lower 60’s for high temperatures. Some parts of western Massachusetts may see some frost warnings Tuesday night, as temperatures fall into the upper 30’s to lower 40’s. As the high moves into the Atlantic, temperatures will warm up, as winds shift to the south and southwest.
We will return to normal temperatures on Thursday and Friday, as highs reach the middle to upper 70’s. As we head into the weekend, a cold front will pass into New England. We may see some showers by midnight Saturday, but we will see light to moderate rain on Sunday, as the front passes through. We will not see clearing skies until early Monday morning, when high pressure ridging builds over the area.
Meanwhile, a tropical system is beginning to die, while another system has come back to life. Tropical Depression Ingrid was centered at 23.7N 99W, or about 75 miles west of La Pesca, Mexico. Maximum sustained winds were at 35 mph, and was moving west at 6 mph. Ingrid has produced heavy rains and mudslides, and 34 people have died due to this system and Manuel from the eastern Pacific. The system will dissipate completely within the next 36 hours. However, heavy rain will continue to hit eastern Mexico.
Tropical Storm Humberto came back to life at 11 a.m. EDT on Monday. As of 5 p.m. EDT, Humberto was centered at 27.3N 45.3W, or about 1210 miles west-southwest of the Azores. Maximum sustained winds were at 45 mph, and was moving west-northwest at 6 mph. The system is forecast to continue moving to the northwest, before slowly turning to the north and north-northeast within the next 5 days. The system will intensify as it moves away from vertical shear. However, the system will become a post-tropical cyclone within 120 hours.
