Powerful low pressure rapidly intensified across the Great Lakes from the 22nd into the 23rd...tracking to Quebec province during the 24th. A secondary low developed across western New England during the 23rd from the occluding Great Lakes low. The secondary low then drew an occluded front across the region through the 23rd into the early morning hours of the 24th. This system brought multiple impacts to the region including very strong winds...heavy rain...thunderstorms...coastal flooding and stream flooding.
A very strong low level jet developed in advance of the occluded front. Winds increased through the 23rd. The strongest winds occurred from the afternoon of the 23rd into the early morning hours of the 24th. East to southeast winds were sustained at 25 to 35 mph...with gusts generally 60 to 70 mph. However...localized gusts up to around 80 mph also occurred. An 80 mph gust was measured near Eastport...with a 78 mph gust at Trescott...both in coastal Washington county. A 77 mph wind gust was reported at Frenchville in northern Aroostook county. The winds caused extensive tree damage with trees uprooted and snapped. The falling trees brought down power lines and utility poles leading to extensive power outages. Power outages peaked during the early morning hours of the 24th when around 55000 customers were without power. Roads were also blocked by fallen trees. A line of thunderstorms accompanied the occluded front across western portions of the region which also locally enhanced winds. The gradient winds and thunderstorms led to several hundred trees uprooted or snapped around the Lily Bay area of central Piscataquis county. The winds also tore the roof from a trailer in Caribou and blew a tractor trailer off the road near Fort Fairfield...both in northeast Aroostook county.
Strong onshore winds and large breaking waves led to coastal flooding along portions of the Downeast coast during the 23rd. The greatest impacts occurred around the time of the late morning high tide. The storm surge at the time of high tide was up to around 2 feet at some locations along with large breaking waves. Several roads and causeways were closed due to overwash...water covering the roads along with deposited debris. Closures included Seawall Road...Moore Road and Hulls Cove Road all in Hancock county. Some roads and causeways were able to re-open after waters subsided and debris cleared. Plows were needed to remove debris from some roads. However...some roads and causeways were damaged or partially washed out leading to more extensive damage. Piers in several harbors were also damaged to varying extents along with beach erosion. Reverse tidal flooding up the Penobscot River led to minor flooding of park land along the Kenduskeag stream during the late evening high tide.
Abundant moisture was also drawn north across the region in advance of the occluded front leading to heavy rain. Warm air was rapidly drawn north. This led to limited wintry precipitation across central and northern areas. Snow accumulations...before the transition to rain...were generally an inch or less across central and northern areas with 1 to 3 inches across extreme northwest areas. Ice accumulations were generally a tenth of an inch or less. The heaviest rains occurred through the afternoon into the evening of the 23rd. Rainfall totals across central and Downeast areas generally ranged from 1.50 to 2.50 inches...with local totals approaching 3.00 inches. Rainfall across northern areas generally ranged from around 0.50 inch to 1.50 inches. The warm temperatures led to melting of the snow pack which released additional water for runoff.  Clogged storm drains helped lead to ponding of water in some areas. Ponding also occurred in some low lying areas. The greatest impacts occurred across portions of central and southern Piscataquis county where several roads and culverts were damaged or washed out and numerous basements were also flooded.
A flash freeze also occurred in the wake of the occluded front during the morning of the 24th with rapidly falling temperatures. Wet roads and standing water rapidly froze leading to slippery road conditions.
