![]() ![]() The cold front will stall south of the area Friday night into Saturday as a sharply positively tilted mid to upper level trough digs into southern New England. Any stronger storms should be short-lived given the weak shear favoring a pulse convection environment. Should the progression of the cold front slow down, there would be more time for diurnal heating and moisture building ahead of the front, and some thunderstorms could become strong. Despite this lift, most moisture looks to build in behind the front, so not all the ingredients needed for strong thunderstorms are likely to exist at the same time.Īdditionally, shear will be on the weaker side, especially for this region. The cold front will serve as a source of lift on Friday, in addition to the upper level trough out of the Canadian Maritimes, leading to more coverage of showers and thunderstorms compared to Thursday. Max temperatures will likely occur earlier in the day and fall through the rest of the afternoon and evening behind the front. Temperatures will be dependent on timing of precipitation onset, as well as how quickly the front pushes through the area as to how much warming will be able to occur beforehand. Partial cloud cover and dew points well into the 50s to near 60 will lead to a mild night with record or near record warm lows in the upper 50s to low 60s.Ī broad range of possible temperatures remains for the day on Friday, as cold air advection will begin behind a backdoor front swinging through the area. Showers will remain possible Thursday night with moisture convergence ahead of a cold front moving in from the north. SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/ Have chosen to add a slight chance across most of the interior forecast area, with a slightly higher likelihood towards Interior Downeast during afternoon, where there will be more moisture available. Models indicate increasing mid-level moisture, which could be enough to trigger a thunderstorm or two. The mitigating factor will be moisture, since the airmass will still be fairly dry. CAMs are indicating a swath of mid-level CAPE, with MUCAPE values around 2000 J/kg in some areas. ![]() Although high pressure will remain dominant and temps are expected to rival today, the atmosphere will be slightly less stable with the approaching front. Across the north, temps may not fall below 60 at some locations.įor Thursday, more uncertainty starts to creep into the forecast. Overnight lows are also expected to be fairly warm, falling into the mid-50s across Bangor region and Downeast, where the air will not heat up quite as much during the day. ![]() This afternoon, temps are still rising around the area, so the possibility of a few broken records still exists for today (see climate section below). High pressure will remain the dominant feature overnight tonight. Still expecting temps to only drop into the u50s/nr 60 acrs the north and the middle 50s over Downeast. Only update early this evening was to import current temps into the fcst and delay temp drop for another hour this evening. High pressure is still in control as skies remain clear acrs the entire area. Only recorded one broken record this afternoon at Caribou. High pressure builds S across northern Maine for the weekend as low pressure develops along the coast and persists into Monday. A cold front will move through the area on Friday. High pressure will move south of the area through Thursday.
