Sunday Overnight Low Temperatures
The incoming high pressure system's northerly winds will keep Maine's low temperatures cool. Down East, Mid Coast, and Portland areas can expect a low temperature in the 50s with northerly winds ranging from 5 to 10 mph. Northern and Caribou areas can expect mid 40s, with calmer winds and partly cloudy skies. Mountainous regions in the northwest can have low temperatures in the upper 30s, so patchy frost cannot be ruled out. No precipitation is expected over the night.
Monday Daytime Temperatures
The warming temperature begins with most areas to feel a high temperature in the upper 60s, and mountainous and higher elevated regions to feel mid 60s. The high pressure system sits partially over Maine, and winds will be light statewide with exception to areas right on the coast, where onshore flow may lower temperatures by a few degrees and winds ranging from 5 to 10 mph. No precipitation is expected during the daytime on Monday.
Monday Overnight Low Temperatures
As the high pressure system moves westerly away from Maine, winds shift to more southwesterly. The winds aren't very strong, but they prevent northern areas from having colder low temperatures. With calmer winds and partly cloudy to clear skies, Mid Coast and parts of central Maine will be slightly cooler, in the mid 40s, than the surrounding areas, in the upper 40s, where cloud cover is a little thicker and helps keep heat from the daytime insolation near the ground.
Warming Temperature Trend Outlook
The GIF above runs from 7 AM Tuesday to 7 AM Friday. The high pressure system will propagate westerly and into New York and Vermont throughout the week. For Maine, this means south-southwesterly winds that will warm up temperatures statewide, and continuing warming until next weekend. Onshore flow in the afternoons will keep coasts slightly cooler than the interior of the state.
Rain Outlook for Next Weekend
The GIF above runs from 7 PM Thursday to 1 AM Friday. A disorganized area of low pressure is shown by short-range models over the Canadian/Washington state border around Tuesday of the upcoming week. This low pressure system is expected to move easterly through the week, and impact Maine or around Maine at the end of the week. The probability of rainfall shown by the long-range model's GIF above are from the potential low pressure system to possibly impact Maine and bring the next significant rainfall to the state. As more information from long-range models are available, we'll keep you up-to-date.
Cold Water Safety
Ocean and lake temperatures for Maine are 50s and 60s respectively. Warm air temperatures doesn't necessarily mean warm water temperatures. Cold water drains body heat up to 25 times faster than cold air. When cold water makes contact with your skin, cold shock causes an immediate loss of breathing control. This dramatically increases the risk of sudden drowning even if the water is calm and you know how to swim. Practice cold water safety by staying out of waters below 70 degrees!
