Area Forecast Discussion National Weather Service Caribou ME 932am EDT Wednesday May 14 2025 Synopsis The center of high pressure will move south of Nova Scotia today into Thursday remaining in control of our weather. Low pressure approaches Friday and crosses the region Friday night through Saturday. Low pressure exists E Sunday. Near Term - Through Tonight 930am Only very minor tweaks made. Mostly sunny skies with just a few high clouds, and warming up fast, on track for the warmest day of the season so far. Previous Discussion... High pressure at the surface and the mid levels will drift off to the southeast today. The resulting deep-layer southwesterly flow will advect warm air into northern and eastern Maine. Model soundings show 925mb temperatures approaching 20C across the Crown of Maine, with 850mb temperatures of 13-14C. In addition, skies will be mostly sunny. This will support areas from the Katahdin region northward reaching the lower to mid 80s outside the highest terrain. Soundings also show mixing reaching as high as 775-800mb from around Route 6 northward. This will result in relative humidity values dropping to 25-35 percent in these areas. Southwest winds will be 5-15 mph, with gusts to 20 mph at times. Will monitor fire weather conditions in the North through the day today. Onshore flow will keep temperatures cooler and relative humidity values higher for the Bangor region and Downeast. Areas north of Route 1 will see highs in the upper 60s, with lower 70s likely north of Route 9. To the south of Route 1, expect highs in the lower to mid 60s, with 50s at the immediate coast and outer islands. Clouds begin to increase tonight from southwest to northeast as the departing high advects more moisture into the region. There will still be enough ridging to preclude any rain showers prior to daybreak Thursday. That said, patchy fog will be possible for the Bangor region and Downeast. The cold waters of the Gulf of Maine will allow Coastal Downeast to see lows in the mid to upper 40s. Inland, it will be a mild night, with lows in the 50s. Short Term - Thursday Through Friday Night A ridge of high pressure will gradually begin to shift eastward Thursday through the end of the week, allowing for a weak shortwave to crest the area during the day on Thursday. Though there will not be much in the way of synoptic forcing with this event, diurnally driven showers are quite possible in this setup. In fact, CAMs are suggesting weak elevated CAPE into the Central Highlands region, which could result in a few isolated thunderstorms Thursday afternoon. Diurnally driven convection should dissipate overnight Thursday night. S to SW winds Thursday into Thursday night will continue to provide warm air advection, though a sea breeze may limit how warm temperatures get Downeast, with a cooler day in store Downeast and the north potentially making a run for at least the upper 70s once more. An other round of diurnally driven convection is in store for Friday. An occluded low will begin to approach the area from the west, but general model consensus is for a slowing of the leading front, with the front likely not pushing into the CWA until later Friday night. The front could move in faster if the supporting upper level trough ends up being more amplified than guidance mean suggests. This will allow for another day of surface heating, which could be thwarted by increasing mid to high level clouds. That said, some scattered rain showers Friday afternoon cannot be ruled out, and if surface heating proves strong enough, another round of thunderstorms are possible across the North s Friday afternoon. An occluded front will lift into the area Friday night, bringing steadier rain thanks to elevated available moisture levels and this increase in forcing. Long Term - Saturday Through Tuesday The occluded front will continue to lift northeastwards through the forecast area on Saturday, continuing rain over the area. A brief dry slot is possible behind this boundary before the main low pressure center crosses the area. There is still some uncertainty on how this occlusion will evolve, with most solutions point towards a triple point low developing along the coast Saturday and enhancing rainfall Downeast. The exception is the 00z CMC run, which delays triple point formation until into the Canadian Maritimes. The latter solution would result in less overall rain in the forecast area, particularly along the coast. Continuing the theme of uncertainty in the long term, the occluded system should exit the area into early next week. Though this is the most likely scenario, there remains uncertainty in how long showers linger into our area behind the system. Once again, the exception is the 00z run of the CMC, with showers quickly exiting the region. Left this forecast with the NBM solution, which portrays the chance for showers lingering into the early week as seen in other global guidance. Marine Near Term: Winds and seas remain well below Small Craft Advisory criteria today and tonight. Sea surface temperatures currently 42-44F from the Downeast coast out 25nm and East to the Hague Line including Passamaquoddy Bay. Patchy fog will reduce visibility on the waters at times tonight. Short Term: Winds and seas will likely remain well below small craft advisory levels through the weekend. Fog is likely to develop over the waters Thursday through Friday, but may begin to dissipate as a low pressure system crosses the area this weekend, bringing rain showers which could also lead to a decrease in visibility. Climate Record high temperatures are possible today, May 14th, at some locations in Aroostook County. Records are unlikely to be broken further south where record highs are warmer.
