  Rich`s Weather Discussion

  Temperatures vary quite a bit this morning and there are some flurries around as well. While here in Peterborough, NH it is 18 degrees, both Keene and Nashua are showing 10 degrees. 
  Skies should turn mostly sunny today with a gusty wind amid milder temps than we have seen in quite a while, in the mid and upper 30s.
  Mulltiple fronts will cross the region over the next few days. We will have some snow showers/squalls Tuesday, then a light snow event Wednesday, starting Tuesday night. Could be plowable. The morning commute will probably be impacted, FYI.
  There is a Hazardous Weather Outlook active for NH & Maine.
  Stay tuned.

  **Near Term (Until 6 PM This Evening)**
  As of 630 AM: Webcams and Automated Surface Observing System (ASOS) reports indicate light snow is falling across parts of western New Hampshire and the higher terrain. High-resolution guidance suggests this snow will move east into western Maine over the next few hours and exit the Mid-Coast by late morning. This could lead to some locally slick travel conditions.
  
  Based on the latest guidance, the coastal waters north of Portland have been upgraded to a gale warning for today, as wind gusts over 35 knots are increasingly likely.
  
  Earlier: Satellite imagery early this morning shows an area of mid-level clouds streaming west to east across the region. These clouds are associated with a mid-level shortwave trough (H5 shortwave trough axis). The 7 PM atmospheric sounding from Gray, Maine, showed very dry air in the mid-levels, with relative humidity only around 50 percent. Despite this, a few reports of light snow flurries have come in, mainly over the higher terrain and near the Canadian border.
  
  Current temperatures range from the teens where clouds have been persistent overnight to near zero in areas where skies have remained clear.
  
  The shortwave trough and its associated surface cold front will move through this morning, exiting the Mid-Coast by early afternoon. This will bring increasing cloud cover to the entire area, along with a few scattered flurries or snow showers. Skies will begin to clear later this afternoon and evening as southwesterly wind gusts increase to around 30 miles per hour. High temperatures will range from the upper 20s in northern areas to near 40 degrees along the coast of Maine and southern New Hampshire.
  
  **Short Term (6 PM This Evening Through 6 PM Monday)**
  A surface ridge of high pressure will briefly build over New England tonight, resulting in partly cloudy skies south of the mountains and mostly cloudy skies over the mountains and areas near the Canadian border. Southwesterly winds will decrease somewhat overnight, but enough mixing will occur to limit radiational cooling. It will still be cold, with overnight lows in the single digits and teens.
  
  Monday will see increasing warm air advection (WAA), which will bring another day of near or slightly above-average high temperatures in the middle to upper 30s south of the mountains. Clouds will increase from north to south during the afternoon ahead of a trough of low pressure and a strong cold front approaching from the north and west. A strengthening pressure gradient and low-level jet (LLJ) will bring wind gusts of 35 to 40 miles per hour, making it feel cooler.
  
  **Long Term (Monday Night Through Saturday)**
  As of 1025 PM: No significant changes to the long-term forecast. The clipper system expected around Wednesday is still indicated, though it does not appear overly impactful. However, there may be some plowable snow. Ensemble guidance is not very supportive of the operational European model's suggestion of an inverted trough behind this system on Thursday. Otherwise, the early week will be warmer before colder air returns behind the clipper Wednesday night through the end of the week.
  
  Earlier: The long-term period will feature occasional cold frontal passages and reinforcing shots of cold air. A clipper system, possibly with weak coastal redevelopment, offers the best chance for light accumulating snow, likely around Wednesday. Afterward, colder conditions return for Thursday and Friday.
  
  Monday night, gusty winds will continue as mixing remains efficient ahead of a sharp cold front. This front will move into northern areas late at night, bringing snow showers and possibly a few snow squalls. The front will quickly move southeast across the region Tuesday morning. Conditions appear favorable for snow showers and squalls, so there is at least a low chance of precipitation during the morning and early afternoon. Post-frontal conditions will bring gusty northwest winds of 30 to 40 miles per hour and falling temperatures.
  
  The next system, a clipper, is supported by both ensemble data and deterministic models. This system is expected to affect the region late Tuesday night into Wednesday. Some guidance hints at secondary development before the system exits. This will result in a good chance of accumulating snow during that period.
  
  After the clipper moves out Wednesday night, high pressure will build in, bringing colder weather to the region.

  Regional Synopsis

  New Hampshire and Maine

  SYNOPSIS...
  A series of weak fronts will cross New England today and tonight, bringing snow showers, mainly to the mountains. Another sharp cold front will pass across the forecast area early Tuesday, perhaps bringing some snow showers and snow squalls. A clipper system may bring some accumulating snowfall around Wednesday. Arctic air then likely makes a return by late next week.
  

  Massachusetts

  SYNOPSIS...
  A cold front moves across the region this morning. Other than a few snow showers in the Berkshires this morning, dry and seasonable conditions are expected today through Monday with blustery to windy conditions at times. The wind peaks on Tuesday with potential for strong winds as a strong cold front moves through, which may also be accompanied by a few snow squalls in the morning. Colder temperatures return late Tuesday and Tuesday night. A fast moving clipper system could bring light snow Wednesday followed by a period of arctic air Thursday and Thursday night. Low pressure may impact the region next weekend with wintry precipitation.
  
  LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
  Key Messages:
  
  * Dry Monday, a robust cold front early Tuesday brings strong wind gusts and the chance of squalls.
  
  * Light snow on Wednesday as a weak clipper system moves through southern New England.
  
  * High pressure builds in to our south, northwesterly gusts and below normal temperatures round out this week, along with potential of sub-zero wind chills.
