Area Forecast Discussion . UPDATED National Weather Service Gray ME 1216 PM EST Thu Feb 20 2020

SYNOPSIS. Arctic air and below normal temperatures can be expected through Friday as an area of high pressure gradually builds in from the west. That high pressure will ultimately build by to our south this weekend allowing temperatures to moderate with continued dry conditions. The next chance for widespread precipitation will come Monday night and Tuesday of next week as an area of low pressure passes near New England.

NEAR TERM /UNTIL 6 PM THIS EVENING/. 1155 AM Update: Just a few minor changes to the forecast to input latest observations, mainly dew points and winds.

915 AM Update: Going forecast is in good shape as of 9am with minor adjustments to sky cover and temperatures through the today period given mid morning observations. There will be some increase in clouds this afternoon with GOES 16 visible imagery showing cloud cover over upstate New York advancing east. It will remain dry however . with dewpoints falling below zero signaling a chilly night upcoming.

756 AM Update: Quick update to drop wind chill advisory with winds having largely gone calm /esp where temps are lowest/ and with temps beginning to move upward from overnight lows. No other changes at this time.

620 AM . Minor ESTF update to reflect the current mesonet in near term grids.

Prev Disc . At 07z . a sprawling 1046 millibar high was centered over the northern plains. With the exception of a few lake effect clouds extending downwind into the upper Connecticut valley and northern New Hampshire . GOES infrared imagery showed clear skies across the area at the moment After a chilly start. temperatures will only rebound to 5 to 15 above in the mountains and upper teens to mid 20s elsewhere in our fresh arctic airmass. A passing impulse may produce a few fair weather clouds for a time later today.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/. Light winds and mainly Clear skies under the surface ridge tonight will make for a very chilly start Friday morning. Lows will range from the teens below zero in the mountains . to 5 below to 5 above in southern and coastal sections. The airmass begins to moderate on Friday with a few passing warm air advection clouds mainly over northern and mountain sections. Highs will range from near 20 in the mountains to mid and upper 20s elsewhere.

LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/. Overview: The long term period can essentially be broken down into two parts: the quiet weather from Friday night through Monday and the more active weather from Monday night into Wednesday. Broad surface high pressure over the southeast U.S. will allow for quiet weather through Monday and warm temperatures on southwesterly flow. A mid-level trough building into the central and eastern U.S. will then allow a return to more active weather toward the middle part of next week.

Impacts: No high impact weather anticipated at this time. However, it is possible that the extended period of warm temperatures could allow river ice to move and cause ice jams next week.

Details: The first half of the long term period is expected to be quiet due to a broad area of surface high pressure parked over the southeastern U.S. through much of the weekend. An area of low pressure over northern Quebec and northwesterly mid-level flow may provide enough energy for some upslope snow showers in the mountains through Sunday, but otherwise, widespread precipitation is not expected and warm temperatures will be the story through Monday. Southwesterly flow around the area of high pressure will allow warmer air to funnel into New England and the result will be high temperatures several degrees above normal. Much of the region will rise into the 40s on Sunday and some locations in southern NH could reach 50 degrees on Monday.

Our weather looks potentially more active for the latter portion of the period due to two factors. First, Sunday night into Monday, an area of low pressure is expected to develop and push east through the central U.S., reaching the Ohio Valley by Tuesday morning and kicking the high pressure over the southeast U.S. out into the Atlantic in the process. That area of low pressure is expected to pass near or over New England on Tuesday. Second, an upper-level trough digs south into the southeast U.S. in the wake of the area of low pressure, potentially putting us in the path of another potent area of low pressure late in the week.

Getting back to Tuesday and Wednesday . much like the previous forecast, an area of low pressure is expected to bring widespread precipitation to our region. The best chances for precipitation are expected during the day on Tuesday. With the warm temperatures continuing on Tuesday, the best guess for precipitation type at this time is mostly rain for southern areas and mostly a rain/snow mix for northern areas. Deterministic global model QPF continues to vary, but it still looks reasonable, based on global ensemble probabilities, that it will be less than a half inch over our region.

The possibility for ice movement on rivers, possibly leading to ice jams, bears watching next week due to the extended warm temperatures and potential for precipitation on Tuesday.

AVIATION /17Z THURSDAY THROUGH MONDAY/. Short Term /Through Friday night/ .

Summary: A large area of high pressure centered over the central United States will reach north and east into New England with quiet weather expected through Friday night.

Restrictions: VFR conditions will persist through Friday night.

Winds: Northwest winds 10G18KTS will diminish to calm/light-variable overnight before shifting west 5-10KTS for the day on Friday. These westerly winds will likely continue outside of the valleys Friday night . with locations like HIE/LEB going calm.

LLWS: No LLWS is expected through Friday. Strengthening westerly winds aloft Friday night will bring the potential for LLWS throughout the area.

Long Term . VFR conditions expected at all terminals Friday night through Monday. It is possible that HIE may see periods of MVFR conditions Saturday into Sunday due to cloud cover. Winds will generally be out of the SW over the weekend, becoming more southerly on Monday.

MARINE. Short Term . Have cancelled SCAs for the outer waters today as winds and seas are below criteria. There is also some light freezing spray.

Long Term . SCA possible for the outer waters late Friday night into Saturday morning as waves build to 5 ft. Seas subside for the rest of the weekend and through Tuesday morning before building again Tuesday evening into Wednesday as an area of low pressure passes over or near the waters.

GYX WATCHES/WARNINGS/ADVISORIES. ME . None. NH . None. MARINE . None.
