National Weather Service Caribou ME
412pm EST Monday Nov 11 2019
Low pressure will track northeast tonight and across Downeast Maine early Tuesday. The low will then track northeast through the Canadian Maritime Provinces Tuesday afternoon and night. High pressure will build in Wednesday through Thursday. A strong cold front will cross the region later Friday followed by cold high pressure on Saturday.
Near Term - Through Tuesday
Low pressure over western PA will track northeast tonight and then cross Downeast Maine Tuesday morning. Overunning snow in advance of the approaching low will continue to develop through late this afternoon and then continue to expand eastward across the rest of the forecast area through early evening. As the low continues to track northeast later tonight, warmer air will push into Downeast areas, including the greater Bangor region, with snow transitioning to a wintry mix later this evening. Along the Downeast coast, snow may transition to a brief wintry mix before changing to all rain later this evening. The warm air will continue to push northeast overnight with snow transitioning to a wintry mix as far north of a Presque Isle to Greenville Line by Tuesday morning. The cold air will remain in place across Northwest Aroostook county, as well as the St. John Valley, where precipitation is expected to remain in the form of all snow through Tuesday. Indications are that there could be some heavier snow banding setting up late tonight and Tuesday morning across far northern Maine, especially the St. John Valley. Thus raised amounts an inch or two to the north and west of Caribou. A Winter Storm warning remains in effect through Tuesday afternoon for Northern Aroostook, Northern Somerset, and Northern Piscataquis counties. A Winter Weather Advisory remains in effect for the remainder of the forecast area, except the Downeast coast, through Tuesday afternoon. As the low continues to track northeast through the Canadian Maritime provinces Tuesday afternoon, colder air will filter in behind the departing low with any mixed precipitation or rain transitioning back to all snow before diminishing by early Tuesday evening.
Short Term - Tuesday Night Through Thursday
By Tuesday evening upper level system will hv mvd to just north of Upstate NY while surface low mvs into the Canadian Maritimes. Snow showers will continue in cyclonic flow as system departs. Med range guidance is giving a potential area of snow showers over the northern and eastern areas, typical in NW flow. Windy conditions are expected during the day Wednesday with guidance hinting at potentially heavy snow showers in the afternoon. Have added in patchy blowing snow across the northwest during the ovrngt hrs as winds kick up bhnd the low. As winds get stronger in the morning and afternoon hv gone with areas of blowing snow for locations that receive strictly snow during the event, mainly nw Aroostook, northern Somerset and Piscataquis cntys. As the area of snow showers dvlp after 15z across the north hv include patchy blowing snow as SLR will allow dry snow to be lofted, hampering visibilities and travel.
Hipressure will build in fm the west on Wednesday night with winds decoupling under clrg skies. A fresh snow cover across most of the area, likely deepest across the north and west will allow temps to drop well below guidance. Cannot rule out mins dropping below zero in the deeper vlys of the North s and the St. John Vly. These will rival record lows on this date.
High pressure will shift offshore Thu morning with return flow on periphery of high bringing temps about 3-5 degrees warmer than Wed. Highs on Thu will top out in the m20s and in the m/u 30s over Downeast.
Long Term - Thursday Night Through Monday
Continuing with the idea of highest probability of precipitation over Downeast on Thursday night. Expect snow showers bringing possible accums to the area by Fri morning but immediate coast looks to be a tad too warm due to onshore flow. Frontal bndry will be poised to enter warning areas Fri afternoon and evening. Srly flow ahd of the bndry will allow surface temps to rise above frzg for eastern and southern zones with mainly snow showers expected across the far nw in the afternoon and a mix of rain/snow showers elsewhere.
High pressure will build in following frontal passage with another shot of arctic air expected. Temps on Fri night will once again drop into the single digits over the North s and even colder on Sat night, although may not have gone cold enuf at this point due to good radn'l cooling conds.
Temperatures will moderate by the end of the period as a trough sets up across the Central Plains with upper level ridging bookending the trough on both coasts.
Near Term: Will issue a Small Craft Advisory late tonight through Wednesday for gusts up to 25 Kt and seas building to 4 to 6 ft. Visibility will be reduced to 1 to 3 NM in rain and fog tonight through Tuesday.
Short Term: Winds will likely be at or above 25kts Tuesday evening with seas ranging from 5-8 ft. Expect seas will stay at these levels into Wednesday afternoon before dropping below SCA (Small Craft Advisory) level late Wednesday night. Winds will increase to gales after midnight Tuesday night in caa, dropping below gales Wednesday morning. Winds rmn above SCA (Small Craft Advisory) levels into Wednesday evng. Conditions will rmn below SCA (Small Craft Advisory) levels until late Thu night before winds and seas increase again. Gales possible once again late Fri night into Sat morning.
