Remnants of Tropical Cyclone Fred to bring heavy rain on Thursday with another tropical threat early next week

8/18/2021

The remnants of Fred to bring potentially heavy rain beginning Thursday afternoon

The remnants of tropical cyclone Fred are currently working their way into the northeast and are forecast to enter southwestern Maine beginning late Thursday morning. A few showers may also develop in central Maine at this time, ahead of the primary rainbands. Rain will continue to move northeast and spread over much of central and southern Maine. The track of the system likely means that northern regions should stay on the drier side. Temperatures will be warm and should reach the 80's in much of the state with the exception of the SW and coast which will likely stay a bit cooler. Also look out for some fog which may develop as a result of the moist airmass in place.

Heavy rain the primary threat from Fred

The rain from the remnants of Fred is likely to be heavy at times due to the very high moisture content present in the atmosphere as tropical air is transported northeast. The largest risk for flash flooding is in the south so be sure to use caution when driving and around areas known to flood.

Rain from Fred exits early Friday morning with clearing skies

The bulk of the rain from Fred should be leaving the state early Friday to the east with skies clearing partially, becoming a mix of sun and clouds. A cold front is likely to move south from Canada throughout the day, allowing for a chance of showers to develop across northern Maine. Temperatures should otherwise be quite warm and are likely to reach at least 80 across much of the region with the exception of the coats and the western mountains.

Warm weather continues into the weekend with mostly dry conditions

During the weekend, high pressure will be situated to the north over Canada keeping the region mostly dry throughout the weekend although it is possible a few showers could develop during the afternoon, more towards southern and central Maine. Temperatures are likely to not be quite as stifling as on Friday but should still reach at least the upper 70’s in most areas and even the lower 80’s in a few places. Mostly cloudy skies will be present throughout the weekend with a few more breaks in the clouds farther north.

Possible impacts from Tropical Cyclone Henri Early Next Week

Tropical storm Henri is currently located south of Bermuda and forecast to turn north and move up towards the northeast in the coming days. There is a threat of some impact to Maine including rain, rough surf, and some strong winds, however, as evidenced by the wide cone for Sunday into Monday, there still exists a great deal of uncertainty. Much of this uncertainty stems from how moving pieces of the atmosphere will interact with Henri. A cold front is forecast to be located in southern New England as Henri is moving north and the strength of the front will determine how close Henri can get to the coast. A Bermuda High as well as high pressure stationed to the northeast of Maine will also play key roles in determining its path and will be important to watch. Make sure to stay tuned for more updates!

Flash flooding can escalate quickly

Temperature outlook through the end of next week

Warm weather ahead especially on Thursday and Friday where temperatures could be reaching the upper 80's. Temperatures should be a bit cooler through the weekend although still relatively warm. A slight cooling trend is possible through the end of next week.
