Good morning! High pressure system moves southeast into the Atlantic today, as a low pressure system to the west moves towards New England. Temperatures rise today into the 80s for inland Maine, and 70s along the immediate coast due to southerly flow. Skies mostly cloudy in the north, and only a few scattered clouds Downeast today. Mid-level shortwaves ahead of low-pressure system may bring some rain showers to the north this evening. Winds could become gusty this evening as pressure gradient over the state tightens. Tonight, low-pressure and associated front begin to cross into Maine, beginning precipitation chances in the northwest. Thunderstorm chances begin to ramp up tomorrow afternoon into evening with diurnal heating and instability developing ahead of the front. Could be some periods of heavy rain and gusty winds with storms that develop. Decent temperature gradient behind the front on Friday, with highs in the north in the 70s, and Downeast in the mid-80s.

For Moderate/High/Extreme hazard risk, more detailed information will be provided via emailed briefings to core partners.
