Today's update is presented by Crowe’s Restoration of Arundel. For emergency fire & water damage (pipe bursts), mold, or biohazard issues in western and southern Maine, call them at 207-467-3152. A messy week ahead FLOOD / ICE JAM CONCERNS FOR THE SOUTH AND EAST LATER IN THE WEEK MONDAY… A bluebird sky and seasonably cold, with most areas running 10° below normal for the day. High temperatures are in the teens north to the 20s south. The northwest wind is in the 5-15 mph range, and the hilltops may see 20-25 mph gusts. MONDAY NIGHT… High pressure skirts off to the southeast, setting up a southwesterly flow with a few clouds. Low temperatures drop back to the single digits below zero in The County, around the plus side of zero for the west and eastern interior, to the low teens along the coast. TUESDAY… Clouds increase throughout the day with a warm front approaching. Snow showers are likely along the Quebec border region in the afternoon, with light rain showers possible for the western foothills. High temperatures range from around 30° to the far north to the mid-40s south. A southwesterly breeze increases during the day, with gusts reaching 20 mph in a few locations. TUESDAY NIGHT… Snow showers are likely for the mountains, and light snow is expected for the north, with an inch or two of accumulation possible. Pockets of light freezing rain may develop over the western and northern interior and the mountain valleys, causing a few slick spots for the Wednesday morning commute. Low temperatures range from the mid-20s in the north to around 32° in the south. Wind direction shifts from the southwest to the south overnight and is generally light. WEDNESDAY… Cold air damming may put up a bit of battle over the interior through midday with pockets of light freezing rain and/or drizzle. A south/ southeast wind flow pumps warmer and more moisture into the region and will become gusty in the afternoon with top-end speeds in the 20-30 mph range. Rain showers work from southwest to northeast throughout the day, becoming more widespread in the afternoon and evening. High temperatures range from the mid-30s for the far north to around 50° to the far south. WEDNESDAY NIGHT…. Windy with rain. Low temperatures in the mid-30s north to mid-40s south. Southerly wind gusts 20-30 mph over the interior and 30-40 mph for the coast and hilltops. INTERIOR FLOODING AND ICE JAM POTENTIAL… The main area of concern is the coastal plain, as the new rainfall and warmer temperatures eat away and release the snow-water equivalent of 1-2+” of liquid in the current snowpack on top of ¾ to 2” of the forecast rainfall. With brooks, streams, and rivers iced up in combination with the frozen ground, the runoff is going somewhere. For those with flood-prone basements, you are on notice. Interior areas with more snowpack should absorb a sizeable amount of rainfall, but there will be runoff between rain and fog. Given the southerly flow that will throw rain at the mountains, the brooks, streams, and small rivers nearby could develop ice jams. We’re looking at roughly a 30ish-hour window with dewpoints above freezing for the mountains and north before cold air returns Friday morning and ends the melting. SHORELINE CONCERNS… Preliminary surf ideas run in the 7-13’ range on Thursday. The only high tide of potential concern is Thursday morning in the 3 AM hour. Still, with water levels falling off the recent astronomical peak, storm surge may cause some minor issues as the high tide also coincides with the low-level jet passing through on the eastern flank of the storm. Overall, I do not expect much of an issue other than minor splash over and some beach erosion. There is still fine-tuning on the forecast to come… stay tuned.
