Area continues to make up for lack of rainfall
Outlook from the Weather Prediction Center for forecast rainfall through Sunday morning is pitching the idea of upwards of 3" of rainfall in western areas of the state. This is good news for those with groundwater supply concerns. After a very dry spring for much of the western foothills and coastal areas, this fall has been a wet one. This event through the first half of the weekend may get most of the drought regions back up to normal for the year.
Main area of concern for some minor or localized flooding is over the western mountains and foothills, southern areas of the Great North Woods and the Central Highlands. Street flooding from clogged storm drains is entirely possible in any urban areas. Saturday appears to bring the heaviest rainfall, but pockets of downpours working in the region on Friday may cause driving and visibility issues as well.
Forecast stays on track
The cold front working into the area Halloween night stalls just south of Maine by Thursday morning. It returns back into the region Thursday afternoon as a warm front, with scattered showers. The Crown of the state sees a snowy mix develop early Friday that may slick the roads a bit, but eventually changes to rain by Friday night.
Model ideas indicate that some of disturbances riding along the frontal boundary could be rather juicy Friday into Saturday. Another concern is a split in temperatures from southwest to northeast, putting the mountains and north in the 40s and the coastal plain potentially in the 60s. With a decent moisture hose attached to the front stemming all the way from the Gulf of Mexico, I'd say there is a reasonable bet for some embedded thunderstorms for the region Saturday. Along with the rain comes the potential for windy conditions, with gusts 25-35 mph or higher possible. Some areas may see power outages.
Once the front kicks out of the region Saturday night, the mountains, perhaps the foothills and the north country may see rain change to a mix of sleet and then snow as cold air gets dragged down from Quebec behind the front. The western mountains may deal with some flurries and squalls Sunday morning as gusty northwest winds at the higher elevations create some down slope frozen precipitation.
