A cold front approaches the region from southeastern Quebec which is likely to bring showers and strong to severe thunderstorms. After the front clears Tuesday night, high pressure moves in bringing a windy, but bright day on Wednesday. Clouds increase on Thursday ahead of a slow moving low pressure system which may linger into the first half of the weekend.
GERT TO STAY WELL AWAY
Tropical Storm Gert is expected to become a hurricane well northwest of Bermuda on Tuesday, but will have no direct impact on New England or the Canadian Maritimes.
The only concern is for rip tides and ocean swells along the coastline late week.
TUESDAY – SEVERE WEATHER POSSIBLE
The day starts off with areas of fog mainly along the coastal plain, some of which may be locally dense in areas.
Clouds become more numerous as the front approaches the region. Humidity builds from a southwest wind increases during the day, with gusts in the 20-30 mph possible in the afternoon.
Showers and strong to severe storms are anticipated to break out around noon, and become more numerous in the afternoon. The best chances for severe weather appears in western and northern areas, but could also be possible along the coastal plain. Storms could contain frequent lightning, damaging wind, downpours and hail. An isolated tornado is possible.
Highs for the day range in the 70s for the north, mountains, DownEast and MidCoast, with 80s for the south and eastern interior around Bangor.
TUESDAY NIGHT
Showers and storms disipate over western and southern areas by late evening, northern and eastern areas in the wee hours of Wednesday. Wind from the southwest slowly settles to the 5-15 mph range, shifting west at 10 mph or less late. Overnight lows range from the 50s north and west, 60s south and east.
WEDNESDAY – FLYING TRASH CAN ALERT™
The day features increasing sun and rather stiff northwest breeze as high pressure moves in for the day. That northwest wind gusting as high at 35 mph could make trash cans, recycle bins, lawn furniture or any other debris to become airborne.
High temperatures for the day range in the 60s mountains and north, 70s for the western foothills on up through Bangor, DownEast and Millinocket, 80s for southern areas.
WEDNESDAY NIGHT
The wind settles a bit but appears to remain rather breezy until late evening. The wind settles down under mostly clear skies, and temperatures settle down with it.
Overnight lows fall into the 40s for the mountains and north, 50s south and east.
EXTENDED OUTLOOK
Thursday sees high clouds gradually increase from southwest to northeast, filtering the sun.
By Friday, clouds thicken in the morning with showers and a possible rumble forming in the afternoon. Rain becomes more widespread and steady through Friday night into Saturday, tapering to showers in the afternoon and evening.
Sunday tentatively looks fair, but a low pressure system moving across central Quebec should be monitored. The system may bring showers to the mountains and Crown as it appears for now, but this is subject to change.
