.DISCUSSION...
As of 236 PM Monday...

KEY MESSAGE 1... A cold front tonight will bring sub-freezing lows
of 29F to Granville and Person counties (Freeze Warning) and patchy
frost to the northern Piedmont and Coastal Plain (Frost Advisory).

Below-average temperatures will persist through Tuesday as a
secondary cold front crosses the region this evening. This front is
moving slightly slower than previously anticipated, which will delay
the arrival of the coldest air and somewhat limit the extent of sub-
freezing temperatures. However, as the front exits overnight, high
pressure will settle over the Mid-Atlantic. This will result in
clear skies and calm windsideal conditions for radiational cooling
where temperature could quickly drop. Thus, a Freeze Warning is now
in effect for Granville and Person counties from 2 to 8 am Tuesday,
with lows expected to reach 29F. A Frost Advisory remains in effect
for the northern Piedmont, northern Coastal Plain, and portions of
the northern Sandhills. Residents in these areas should expect
temperatures between 33F and 36F, creating the prime environment for
patchy frost especially in rural areas that can damage uncovered
outdoor plants.


KEY MESSAGE 2...Temperatures will be above normal through the
extended forecast period. A cold front could possibly bring some
rain this weekend.

With a shift to southerly flow on Wednesday, temperatures will rise
above normal, with highs in the 80s through at least Saturday, and
bring an end to any overnight temperatures around freezing. While
some models suggest that areas along the VA/NC border could receive
a brief sprinkle Wednesday afternoon/evening, have removed the
chance of rain from the forecast considering how dry the sub-cloud
layer in the atmosphere will be. A more substantial chance of rain
will arrive this weekend with a cold front, but considering how
yesterday`s cold front underperformed with rainfall totals, will not
get too optimistic about rain chances this weekend until that time
period is closer. Whether or not much rain occurs with the front, a
shift in surface winds back to the north should drop highs back into
the 70s for most locations on Monday.

.AVIATION /06Z TUESDAY THROUGH SATURDAY/...
As of 145 AM Tuesday...

Canadian high pressure and dry, continental air will progress across
and offshore the srn Middle Atlantic with associated light and
variable surface winds and high probability of VFR conditions over
cntl NC through the 06Z TAF period.

Outlook: Marginal LLWS will be possible mainly over the Piedmont Wed
morning, followed by gusty wswly surface winds with daytime heating
and ahead of a moisture-starved cold front Wed. That front and a
related band of VFR, altocumulus may result in light, VFR
rain/showers near and north of RWI late Wed afternoon and evening.
Moisture and a stronger frontal system will approach and provide a
chance of rain and flight restrictions on Sat.
