should enter SW Mississippi around 9 pm, KMCB 10 pm, KBTR 11 pm,
KHDC midnight, KNEW/KGPT between 1-2 am, KPQL 2 am. Deeper, colder
air and winds may be in lag about 1 to 2 hours after initial wind
shift but by daybreak, all areas should be in full bore cold air
advection with temperatures falling early, leveling off and
warming slowly as clouds thin later in the day. Anticipating
clouds to clear for optimal radiational cooling coupled with deep
drainage trajectory and weaker cold air advection to bring
temperatures to record lows for mid-November. After some
collaboration with surrounding offices, attempting to get W/W/A
align with neigbors and best convey the message. We are probably a
bit early for Freeze Warning but given the higher than normal
confidence for this event, have blended with the surrounding
offices on Freeze Warning for tomorrow night. The four SW MS
counties could be a Hard Freeze Warning, but this would look
arkward, so addressing in the Freeze Warning and leaving room to
upgrade on next couple of packages if still indicated for tomorrow
night.
.LONG TERM...
Fortunately, this arctic event appears to be very short-lived with
a warming trend expected to onset later Wednesday as the frontal
zone becomes quasi-stationary across the lower gulf and some
rippling takes place to induce some weak isentropic lift over the
boundary. This is a softer solution than previously indicated with
PoPs lower than before for Thursday. Re-enforcing high pressure
builds latter part of the week to maintain colder than normal
conditions but not as cold as Tue night/Wed morning.
&&
.MARINE...
Front should start to slip off the coast around 2-3 am off LA
coast and 3-4 am MS coast. North winds should increase rather
abruptly with cold air advection hitting the warmer waters to ramp
winds to near gale conditions towards daybreak. Gale Warning
placed for 3 am west of the river, and 6 am east of the river
through about sunset Tuesday. Seas to build to 14-17 feet well
offshore. Conditions improve steadily after cold air advection
abates Tuesday night with considerably lighter winds and lowering
seas expected for Wednesday. Another surge of cool air moves off
the coast Friday but with lesser affect than the initial front.
