.DISCUSSION...

Quiet weather will be in store to start the weekend, but then expect
stormier/wetter weather over the region from Sunday through early
next week.

Today through tonight:

A cool polar airmass associated with a progressive thermal trough 
crossing the ArkLaMiss will combine with considerable cirrus and 
northerly breezes to make for a chilly day. Abundant mid/high level 
subtropical moisture is being drawn into the south central CONUS by 
a cutoff low centered over the Gulf of California. This moist air
is being lifted sufficiently for widespread light rain along the 
TX/LA coast. and some of this activity may manage to reach as far
north as the Highway 98 corridor in southern MS by late this
morning into early afternoon. Otherwise, expect clearing skies 
tonight to allow for cold overnight lows from the mid 20s to near 
30 over much of the forecast area. /EC/

Saturday through next week...

A more dynamic weather pattern will begin to take shape over the 
weekend and persist well into next week. Several chances of rain and 
storms will exist through the period as several disturbances 
traverse the region.

A surface high centered over the SE and mid level ridging should 
keep Saturday dry with temperatures around average mid December 
values. Moisture will increase later in the day on Saturday and into 
Sunday as the surface high progresses eastward towards the Atlantic 
Coast, allowing for return flow over our region. A de-amplifying 
shortwave trough embedded in the prevailing upper SW flow pattern 
will bein to approach the region on Sunday. Pwats will have 
increased to above 1.5" areawide on Sunday ahead of this first 
disturbance. Rain chances will begin to increase from west on Sunday 
morning as the front associated with this feature begins to move 
into the area. Scattered thunderstorms will be possible mainly in 
the southern portions of the ArkLaMiss on Sunday. The best 
instability will exist south of the ArkLaMiss but impressive Bulk 
shear values will exist in the region with 0-3 km bulk shear around 
45-50 kts and 0-6 km Bulk shear around 50-60 kts. This could lead to 
some strong storms with damaging wind gusts as the main threat. Any 
over achievement in instability could further this threat. A 
marginal threat of severe weather will be introduced in the HWO for 
areas along and south of the US 84 corridor. 

Moist air will continue to be advected into the region from the Gulf 
of Mexico through mid week as more disturbances embedded within the 
SW flow aloft impact the region. Chances for heavy rain/storms will 
exist once again on Tuesday/Wednesday as another surface front 
provides sufficient lift to the region. Rain chances will be present 
each day during the upcoming week. The expected rainfall will 
provide relief to our rainfall deficits and ongoing drought 
conditions. Long term models are hinting at a pattern change by next 
weekend. /JPM3/

gales, and more than 20 inches of snow in interior New England. There was
great loss of life at Gloucester MA. (David Ludlum)
...1901...
An intense cold front swept across the eastern U.S. The cold front produced

Ludlum)
...1945...
A record December snowstorm buried Buffalo NY under 36.6 inches of snow,
with unofficial totals south of the city ranging up to 70 inches. Travel
was brought to a halt by the storm. (14th-17th) (The Weather Channel)
