 A well-defined upper low brings the risk of showers and storms for much of the region for the day. The deep trough associated with it is sandwiched between ridging to the west and east, squeezing the upper low like a lemon. This is another screwy setup with low tracking to the southeast over western areas, with moisture on the east tracking north, and to the west, more to the south.  The southwest side is where the concern lies for strong to severe storms. For Maine interests, this is primarily an isolated threat. The cold pool aloft is not quite as pronounced as the region experienced last week, but the freezing level is around 11-12,000 feet. Low-capped, slow-moving dumpers and trainers are possible; localized flash flooding is likely where that happens. With the low freezing level comes the threat of small hail. Damaging wind is also possible, given the rather steep temperature lapse rates. If the sun comes out, pay attention to the sky.  On the northeastern side, isolated to scattered showers are possible. Fog may be an issue along the DownEast coast, which could cause temperatures to bust on the low end where it stubbornly holds on and keep them in the 60s. MONDAY NIGHT: Where rain falls, expect fog to break out, which may be locally dense in spots. Fog could also be an issue in the DownEast areas. The dew points drop back a few degrees to the mid- to upper 50s, and those are the low temperatures. TUESDAY: A mainly dry day for the region, with warmer temperatures. A cold front approaches from the northwest in the late afternoon, which brings the risk of a shower along the Quebec border region. Highs for the day range in the mid-70s to low 80s, cooler along the MidCoast and DownEast shorelines. EXTENDED OUTLOOK: Isolated to scattered showers are likely for Wednesday. Dry conditions are on the way for Thursday and Friday. Saturday continues to look showery. The region may get a mainly dry day away from the mountains on Sunday, with a chance of showers for Labor Day. Stay tuned for revisions.   Always have MULTIPLE ways to receive weather alerts.
