A warm day today with temperatures near record highs in the low 80s F comes to an end this evening as a cold front pushes through from the northwest. This brings showers and periods of rain along with a period of much cooler weather. Southwesterly winds ahead of the front shift sharply northerly, then continue to veer becoming easterly and strong at times on Monday as today’s front becomes stationary near to the south of the island.
With the now stationary front to the near south of Bermuda, cloudiness, showers, or patchy rain remain in the area through Tuesday. Another frontal system begins to develop along the US East coast on Tuesday morning and pulls the stationary front northward. Winds veer from easterly to southeasterly during this time, remaining mostly moderate. The frontal system is expected to move east-northeastward beyond Tuesday.
Meanwhile, a tropical low currently just north of the Turks and Caicos Islands is being monitored by the National Hurricane Center for the possibility of tropical depression or storm formation as it tracks west-northwestward. As of their 3pm update, the NHC is giving this tropical low a ‘high’ 70% chance of becoming a tropical cyclone either tonight or tomorrow should the current pace of development continue. Aircraft Reconnaissance is scheduled to investigate the low tomorrow morning as it begins to impact the Bahamas Islands. By Tuesday, the potential tropical storm will begin to turn to the north then northeast as the frontal system developing along the US East coast begins to change the regional steering flow.
Cooler drier air around the frontal system and cooler sea surface temperatures along the potential tropical storm’s track beyond Tuesday will likely result in a weakening trend. It is likely that the frontal system absorbs whatever is left of the potential tropical storm. But the possibility exists that a weakening tropical cyclone could pass close enough to Bermuda to bring strong winds and gusty showers on Wednesday as the weakening potential tropical storm and cold front move through. Much cooler and less humid weather can be expected for Thursday.
