.SYNOPSIS...
A cold front will move through on Monday with low pressure
developing along it, bringing a wintry mix to portions of the area.
High pressure will build back over the area mid week. Another low
and cold front move in late in the week.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 2 AM Sun...Another raw, cool and cloudy day for ENC with
highs stuck in the 40s. For tonight, partial clearing occurs,
leading to patchy to areas of fog, locally dense at times, esp
nwrn counties. No freezing fog expected, as temps will be warmer
than last night. Lows range from 32-36 inland, to the 40s along
the coast.

&&

.SHORT TERM /MONDAY/...

Key messages...

- Wintry mix expected Monday afternoon to evening northwest
  counties.

- Black ice formation Mon night to Tue AM as temperatures fall
  into the 20s. Wet roads from rain and snow Monday become icy
  later Mon night, impacting the Tuesday morning commute.

As of 2 AM Sun...Tricky fcst upcoming with p-type and snow
amount challenges for your Monday. Shortwave trough will swing
through swings through the Southeast states, while sfc
cyclogenesis occurs off the Carolina Coast. A combination of
lowering thicknesses through the day, along with column cooling
through inc lift/uvv and precip loading will lead to rain
changing to a ra/sn mix, possibly mostly snow for our nwrn
counties. Model differences abound however, with some of the
guidance (NAM/FV3/GFS) indicating a colder column and more rapid
changeover to snow, while the Euro, AIFS, CMC, HRRR are warmer
aloft and retain snow the far northwest. Have based the
forecast and snow amts on the ECM, which as been quite
consistent, with any accums relegated to the far nwrn counties.
Probabilities for 1" of snow are ~30-60% along the Hwy 64
corridor from Plymouth to wrn Martin county, ~10-30% for the
Hwy 264 corridor from Washington to Farmville in Pitt County.
This makes the most sense, as temps will be well above freezing
through the day Mon, making it difficult for snow to
accumulate. The NAM/GFS are too bullish on snow amounts given
the warmer initial conditions. By the time temps fall to
freezing and below Mon evening, snow should be tapering off
quickly from w to e. For the eastern and southern counties,
predominantly rain is fcst.

.LONG TERM /MONDAY NIGHT THROUGH SUNDAY/...
As of 3 PM Sun...

Key messages...

- Black ice formation Mon night to Tue AM as temperatures fall
  into the 20s. Wet roads from rain and snow Monday become icy
  later Mon night, impacting the Tuesday morning commute.

Dry and seasonably cold mid week. Another weather maker
possible by week`s end, turning much colder next weekend.

Monday night through Tuesday...Biggest impacts from the snow
and precipitation will be the development of black ice, as
temperatures fall through the 20s during the overnight period.
Any rain or snow that falls during the day will freeze up
overnight, esp on elevated surfaces like bridges and overpasses,
leading to hazardous contions for the Tue morning commute.

Wednesday through Thursday...Dry conditions expected as high
pressure builds back in at the surface. Highs in the 40s Tue
warming back into the 50s to near 60 Wed and Thu as winds
become Sw. Good radiational cooling will bring lows into the 20s
for most of Mainland ENC, with 30s on the beaches and OBX Tue
night/Wed morning.

Friday through Saturday...Next chc for precip arrives by week`s
end, as next shortwave trough swings through the Ern CONUS.
Latest 07/12Z model suite has trended drier however, so pops
have not been raised, and remain at 20-30%. At this time, ptype
looks to remain all liquid. Much colder air expected behind the
front for next weekend with highs back into the 40s and lows
in the 20s.

.AVIATION /20Z SUNDAY THROUGH FRIDAY/...
As of 2 PM Sun...

Key Messages...

- Improving conditions this afternoon, but some areas of IFR
  ceilings will remain across the northern coastal plain

- Brief improvement to VFR conditions likely this evening

- IFR/LIFR ceilings and/or visibilities return tonight through
  tomorrow morning

- IFR conditions will likely persist through most of tomorrow as
  rain/snow moves into the area

Flying conditions have improved to MVFR/VFR in many locations
across ENC, but there remains some pockets of IFR ceilings
across the northern coastal plain. These areas may persist
through this evening while the rest of the forecast area likely
remains VFR.

Tonight, skies will briefly clear or partially clear for most of
the area, and the combination of slight radiational cooling and
a very saturated surface layer will result in the reformation of
fog, and also low stratus. Fog is likely to become very dense
again across the coastal plain, and even as far east as US 17.
Similar to last night, areas of very low stratus will also
form, but its unclear what the predominate impact to flying
conditions will be overnight and into tomorrow morning. Rain and
potentially snow will be moving into ENC after sunrise tomorrow
morning, and IFR conditions are likely to continue at least
into the afternoon if not all day.

Outlook: Sub-VFR conditions may persist Monday night before VFR
conditions return through at least midweek.
