Scattered showers and storms, but severity uncertain
A warm front will approach the region for Wednesday, bringing scattered showers and thunderstorms along with it. Northern and western areas are the main areas to be effected. as they are in the marginal risk, but an isolated shower or thunderstorm cannot be ruled out in other regions of the state. However, the timing and severity of the storms depends on what happens during the morning hours. A subtle shortwave will pass through the region at some point during the morning and bring some rain showers, then the secondary (stronger) wave will move through during the afternoon hours. If the initial wave comes earlier in the day, the storm threat will be greater during the afternoon hours, but if it comes later, the storm threat will be lower. If the initial wave comes through earlier and storms pop-up in the afternoon hours, the biggest threat with these storms would be gusty winds, small hail and the potential for flash flooding. If the initial wave comes through later, thunderstorms are still possible in the afternoon, but likely wouldn't be as severe. We will likely put out another update in the morning to keep you updated on how the system has progresses. Otherwise, keep an eye on local news tomorrow for the latest updates on this situation.
As for temperatures, Maine will see temperatures ranging from the mid 70s to the mid 80s. Southwestern portions of the state will be the warm spot and feature temperatures in the low-mid 80s. Areas extending north from Augusta to the Allagash region will see upper 70s, and the entire eastern portion of the state and the coast will see mid 70s.
It will also be very muggy tomorrow in some regions of the state. Southwestern and western areas of the state will have dew points in the upper 60s and even some isolated low 70s. The rest of the state will mainly feature dew points in the mid 60s, with some low 60s Downeast.
As for the overnight forecast, temperatures will drop into the low 60s statewide with some mid 60s in southwestern regions. Fog is likely overnight, especially where it rained during the day, in western regions and along the coast.
Heat and humidity moves in for the end of the week
Temperatures will warm up into the upper 80s and low 90s by Friday. Rain will move in for Saturday, so temperatures will cool back down.
Though temperatures will cool down a bit for the weekend, dew points will stay consistently in the mid/upper 60s throughout the weekend. Looks like this pattern may be sticking around for a while, at least in the southern regions.
The end of the week is forecast to have temperatures in the upper 80s and low 90s with relatively high dew points, which can create dangerous conditions. It's very important on hot and humid days to stay hydrated and stay inside as much as possible. If you go out and have pets/children, NEVER leave them in the car because the temperature inside can quickly become dangerous or even life threatening. Also, don't forget to reach out to elderly family members, friends, neighbors, etc.. that may not have air conditioning.
