Thursday: Warm temperatures and partly cloudy skies
A lingering high pressure sits northeast of Maine and will be moving east as the day progresses. As this happens, skies will increase cloud cover into the evening and overnight Thursday. Daytime temperatures range from upper 60s to low 70s state wide, with some spots in the Portland area possibly reaching into the mid 70s. Calm southerly winds may keep the coast temperatures in the upper 60s, but nothing less than that. Dew points will sit comfortably in the 50s statewide.
Friday: Warm front moving through, bringing rain and slightly increased temperatures
A low pressure system sitting just to the north of the state will be moving east on Friday, bring rain as the warm front pushes through from the west. As it does, warmer, more moist air will push into the western regions of Maine, bringing slightly increased temperatures in the mid to upper 70s and increasing dew points to the low 60s. As the warm front progresses easterly throughout the day, all of Maine's temperatures will increase as well as dew points. Winds pick up as the front progresses, ranging from 7 to 11 mph statewide.
The GIF above runs from 5 AM Friday to 8 PM Friday and shows reflectivity from a short-range model. This is the progression of rain showers and embedded thunderstorms through Friday. This particular model sometime overestimates reflectivity and is also a high resolution model, so some widespread green reflectivity may not be precipitation that actually happens. Thunderstorms embedded in the widespread precipitation looks to affect the Portland areas the most, but thunderstorms are susceptible statewide as this warm front moves through the state.
Maine Hurricane Preparedness Week
One of the most important things to remember when preparing for the hurricane season is assembling disaster supplies. Making a checklist and assembling necessary items before the season begins saves you from scrambling during an imminent storm situation. Use the image graphic above for any guidance when creating a checklist and assembling supplies for the hurricane season.
