Tuesday: Hot and Muggy, Partly Cloudy Skies
Temperatures and dew points are similar to previous days; muggy feeling, with northern Maine in the mid 80s, central and western Maine in the upper 70s, and Down East, Mid Coast, and Portland areas in the upper 60s to low 70s. Cloud cover increases as the day heats up, resulting to partly to mostly cloudy skies. The usual summertime pop-up thunderstorms as less likely today, due to lack of energy and instability for these storms. Extreme northwestern Maine may see some storms in the distance or close by past the border into Canada, where more of the energy is concentrated.
Wednesday: Slight Cool-down in Temperatures
Temperatures begin to dip tomorrow afternoon as a cold front approaches the state from the west. Statewide, we'll see temperatures in the 70s, with some patches of upper 70s in the extreme southwest region, near Portland. Down East is slightly cooler, due to onshore flow, and will see high temperatures in the mid 60s. It'll be a mostly cloudy day with some regions being totally overcast for a few hours.
The GIF above is from 7 AM Thursday to 7 PM Thursday. Looking ahead into the week with long-range models suggests Maine staying in the 80s for Thursday. This same run suggests Maine will also be in the 80s for Wednesday as well. Although it can be a possibility, as the cold front pushes through the state on Wednesday, I believe small patches of Maine in the Portland area may have the ability to reach into the 80s, but not much more north than the Portland area.
With summertime temperatures comes the summertime thunderstorms across the nation. One of the hazards of a thunderstorm is lightning. The chance to be struck by lightning may be slim, but you have increased chances if you ignore the signs of an oncoming storm. If you hear thunder, move indoors if possible. Many fatalities come from ignorance, staying outdoors to finish up their activities, saying "five more minutes". Practice lightning safety by moving indoors and out of water when you first hear thunder.
