1020 pm update... Cold front is currently on the coast and just about to push offshore. Skies hv gnrly cleared acrs entire CWA with coastal areas down in fog for the time being, however once winds kick up do not anticipate this to be much of an issue for more than an hr at this point. Hv lowered temps acrs nrn areas into the l/m 20s ovr deeper vlys, leading to widespread frost by mrng. Dwpts upstream hv already dropped into the teens acrs Quebec and expect these wl mv into the Crown within the next few hrs. No other major chgs needed with this update. Prev discussion blo... A cold front will continue to move across Maine this evening. Surface temperatures across the area are in the upper 50s to lower 60s. This should be cool enough to keep convection under control with just showers and perhaps an isolated clap of thunder. Further south in Maine surface temperatures are in the lower 80s and thunderstorm potential is significantly higher. The front should clear the coast this evening with drier air moving in and clearing.

&& .SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/... High pressure dominates the weather on Wednesday, with a weak frontal boundary trying to drop south across extreme northern portions of Maine. At best, the boundary should only produce some scattered showers. The front quickly moves out of Maine and high pressure returns for late Wednesday night. && .LONG TERM /FRIDAY THROUGH TUESDAY/... High pressure remains in control on Thursday and Friday, with little in the way of weather. A weak coastal storm looks like it will try to develop over the mid Atlantic coast Saturday morning, but it gets sheared apart and will likely only result in some very scattered precipitation Sunday and Monday. && .AVIATION /02Z WEDNESDAY THROUGH SUNDAY/...
