A weak trough of low pressure crosses the area Saturday night, followed by a cold front approaching later Sunday. The cold front weakens across the region on Monday. High pressure builds toward the region Wednesday. && .NEAR TERM /THROUGH SUNDAY/... 1030mb surface high over Wisconsin as of 05z tonight with ridge sprawling into ern Canada has resulted in light north winds at higher elevations while lower elevations have decoupled. Temps have bottomed out over North Woods with some locales approaching the u30s, very similar to what happened last night. Global CMC bias- corrected seems to have the best handle on temp drop this morning and have hedged twd those numbers with low-middle 40s across the north for lows while southern areas dip into the lwr 50s just before sunrise. Radiational cooling will allow river valley fog to form through the morning hours. Skies start out sunny this morning with clouds increasing across the north in the afternoon as wave approaches. Shortwave currently located over James Bay will be dropping south and bring an isolated shower or storm to the St. John Valley this afternoon. Wave not progged to move into NB until after 03z this evening and have maintained isolated showers acrs the north for this reason. By Saturday evening smoky skies from Canadian Wildfires will begin to the move into the area and have included haze mention in the forecast for central and northern areas overnight. Min temps wil be near to slightly below normal as winds shift around from the southwest. Cold front will be located well to our north by 12z Sunday with westerly flow at the surface and aloft bringing more smoke in from Canada. Models indicating more surface smoke vs aloft for Sunday and have mentioned smoke in the forecast, mainly for areas north of a line from the Central Highlands into southern Aroostook. Forcing from front dropping twd the area may result in showers and storms acrs the St. John Valley Sunday afternoon in increasingly unstable airmass. However, may need to back off on timing of convection as front movement has slowed over the past several model runs. Temps warm into the 80s ahead of the front as H8 temps warm to near +15C in the afternoon. && .SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/... Sunday night: The cold front is expected to enter the region pushing showers into the north. Models are in good agreement with the front weakening by the time it enters into the state. The lose of diurnal heating will also decrease rain chances into the night. Temps should be in the upper 50s. Monday: The cold front should be through the north and into the Central Highlands by the morning. Temps should be mainly affected in the north with the early frontal passage. Expected temps in the north in the mid 70s. The front should be completely out of the region by the evening. The south is expected to remain warm throughout the day with the S winds. Expect temps in the mid 80s. Monday night: High pressure should settle back into the region. Mainly clear skies should drop temps into the low 50s to upper 40s. Patchy fog is possible with the cooler temps and calm winds, but confidence is low at those point, so did not include in the forecast. && .LONG TERM /TUESDAY THROUGH FRIDAY/...
