KEY MESSAGE 1...Rain is expected this evening. This combined with above normal temperatures through Wednesday will continue to erode any remaining ice on northern rivers. KEY MESSAGE 1 DESCRIPTION...A brief period of rain is expected early this evening before ending later this evening. Rainfall through tonight is expected to range from one quarter to around a half inch. A stray clap of thunder is not totally out of the question, especially along the coast. Continued unseasonably warm temperatures combined with any rainfall will continue to erode any remaining ice in the St John river basin in far northern Maine. KEY MESSAGE 2...Warming temperatures through the end of the week, along with rainfall, will continue melting the remaining snow and ice in norther Maine. KEY MESSAGE 2 DESCRIPTION...Temperatures above normal throughout the rest of the week. generally with daytime highs in the 50s throughout northern and eastern Maine. Overnight lows generally in the 40s, and creep back into the mid-to-upper 30s by the end of the week. This extended period of warming temperatures, along with some potential rain Thursday night, will continue eroding snow/ice, and northern Maine river ice. KEY MESSAGE 3...Very slight chance for some thunderstorms Downeast Thursday evening into Friday. KEY MESSAGE 3 DESCRIPTION... Shortwave and low pressure system moves through late Thursday into Friday morning. Moisture advection, alongside weak frontal passage, with decent lapse rates and shear, work in favor of some minor thunderstorms developing. That being said, there is a deep inversion a few hundred feet above the surface, that would cap any storm development in the region. Decided to keep a slight chance for storms in the forecast, but temperatures would need to warm up for chance of a rumble of thunder. The chance of thunder is under 15 percent. && .AVIATION /00Z WEDNESDAY THROUGH SUNDAY/... Tonight...VFR early this evening, then MVFR/IFR, rain this evening.
