Most areas of the state will have a chance for showers this Independence Day. A disturbance aloft has brought unsettled conditions to the region, making way for cloudy skies and numerous rain showers. Some folks may be waking up to rain this morning after a wet and showery Saturday night. The southern half of the state is most likely to receive significant precipitation on Sunday, but the chance for showers extends to those in northern areas. If you are planning to spend time outdoors for the 4th, keep in mind that these plans may be affected by the rain.
High temperatures on Sunday will likely only reach the high 50s to lower 60s in southern regions. Areas in the northern part of the state are expected to be a bit milder in the mid to upper 60s, depending on how much sun is able to filter through the mostly cloudy skies. Showers are most likely during the morning and are expected to taper off towards the afternoon. Total rainfall amounts of .25-.50 inches are likely, with locally higher amounts of up to 1 inch possible for areas caught in slower-moving showers. While it is unfortunate that this wet and gloomy weather has to come on a holiday, the rain will be welcomed for those feeling the effects of drought.
Most of the precipitation should begin to lighten and clear out by the evening, as the upper-level trough makes its way through the Gulf of Maine. Lows on Sunday appear to be quite cool with temperatures falling into the upper 40s to lower 50s. Skies should begin to clear Sunday night into Monday as dry air is advected in from the northwest.
Monday is shaping up to be the most pleasant day for the long holiday weekend. Southerly flow, combined with a ridge of high pressure beginning to build over the area, will likely result in warmer, drier conditions. Temperatures are expected to be much more seasonable in the 70s. Partly sunny skies should allow for one last chance for outdoor 4th of July plans.
Heat and humidity return on Tuesday as the continued southerly flow carries warmth and moisture along with it. 90° temperatures will be possible on this day, along with showers and thunderstorms. A cold front is expected to bump temperatures down a few degrees on Wednesday, with another round of precipitation possible on Thursday as a low pressure system approaches. The track of Hurricane Elsa, which is currently headed for Florida, could potentially bring rain to Maine in the coming days, so stay tuned for future updates!
