.WHAT HAS CHANGED...
Slight adjustment in timing of frontal passage as well as lowered
dewpoints early in the work week.

&&

.KEY MESSAGES...
1. A cold front will pass through the area today and tonight,
bringing continued widespread rainfall. While there will be a few
thunderstorms and locally heavy rainfall, the risk of flooding
rain or severe weather remains low.
2. Frost still possible across the mountains and possibly a
few parts of the North Carolina I-40 corridor each night from
Monday night through Wednesday night. Protection of sensitive
vegetation may be required Tuesday night and Wednesday night in
some locations.
3. Fire weather will gradually become more of a concern through
mid-week as a dry air mass spreads across the region. Outdoor
burning could become dangerous by Wednesday afternoon due to low
relative humidity values and dry fuels.

.DISCUSSION...
Key message 1: A cold front will pass through the area today and
tonight, bringing continued widespread rainfall. While there will be
a few thunderstorms and locally heavy rainfall, the risk of flooding
rain or severe weather remains low.

Upper trough is pushing into the Appalachians at AFD time, dragging
a front across the East Coast. Deep Gulf moisture advecting in in
the SW flow aloft combined with plenty of synoptic scale lift has
kept much-needed showery conditions on this Easter Sunday, with some
locally heavy rainfall. As the front pushes east, increasing
instability will allow for some increased convection this afternoon,
but with unfavorable thermodynamics, the best convection will be off
to our east where the environment has had additional time to
destabilize. HRRR/RAP do want to develop some semi-linear convection
mainly across our southeast zones, including the Charlotte metro,
but do not expect any severe.

Behind the front, strong CAA will allow a cooler and drier airmass
to filter in, with lows tonight almost 20 degrees cooler than last
night and just a smidge below early April normals. Sunny and
beautiful day on Monday with highs very close to normal. With the
dry airmass in place, RHs will drop into the 20s and 30s across the
area, but today`s wetting rain will help with fuels.


Key message 2: Frost still possible across the mountains and possibly
a few parts of the North Carolina I-40 corridor each night from
Monday night through Wednesday night. Protection of sensitive
vegetation may be required Tuesday night and Wednesday night in some
locations.

Influx of colder air remains on track to commence tonight with NC
mountain pre-dawn minimum temperatures in the 30s.  Values around
freezing will be limited to just the highest elevations. After the
return to near climo maximums on Monday, a limited threat for frost
development arises by early Tuesday morning for those NC mountain
locations which can decouple, which typically means the deeper
valleys.

As the center of a stronger high pressure center translates from the
Great Lakes to the NE CONUS Tuesday, a reinforcing shot of colder
air makes it way south into the region. Pre-dawn minimums
both Wednesday and Thursday are still creeping upward and given the
pressure gradient fcst to be in place, considerable mixing should
limit any frost potential to just the deeper NC mtn valleys.

Note that the frost/freeze program remains inactive across the
northern mountains of NC, so altho some parts of the nrn mountains
might get below freezing Tuesday night, a freeze warning will not
be issued and the fcst will be allowed to speak for itself.


Key message 3: Fire weather will gradually become more of a concern
through mid-week as a dry air mass spreads across the region.
Outdoor burning could become dangerous by Wednesday afternoon due to
low relative humidity values and dry fuels.

Afternoon relative humidity values will likely tumble to below 30
percent each afternoon beginning on Monday.  Thanks to an increasing
pressure gradient, there is a risk of low amplitude easterly wind
gusts developing Wednesday afternoon, but the risk for reaching red
flag criteria remains low.

Beneficial rain today should keep fuels wet enough on Monday, but
the dry air mass and a light NW to N wind should provide the
opportunity for fuels to dry out through Tuesday afternoon. By
Wednesday afternoon, even though high temps will drop compared to
the previous two days, the low RH might become more problematic if
fuels dry out as expected, because of better potential for wind
gusts above 20 mph. Land managers will want to keep track of this
forecast problem. Once the sfc high shifts farther offshore by
Thursday, some Atlantic moisture should begin to return and
afternoon RH rises accordingly.

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
At KCLT and elsewhere: Widespread -SHRA at TAF time, with enough
instability to warrant keeping in the PROB30 TSRA for most sites
this afternoon. Confidence is low on impacts to the terminals but
cannot rule something out. Mainly MVFR to IFR cigs this afternoon
will remain for several hours, with rapid lifting behind the front.
SW winds will shift to NW, though with the front slowing down from
the earlier forecast, have pushed back wind shift at KCLT to 22z.
Brief gusts possible as well. Winds will shift around NNW to N
overnight, with some LLWS possible especially across Piedmont TAFs
between 00-12z. Have only included this at KGSP and KGMU for now.
VFR through the erst of the period.

Outlook: High pressure spreads over the region behind the front
tonight and lingers through the middle of week with dry/VFR
conditions expected through at least Thursday.
