Area Forecast Discussion

.DISCUSSION...
00Z New Years 2021 TAFs

&&

.AVIATION...
RA & VCTS to persist thru the evening. Squall line moving up thru
SWLA / CenLA. Winds will continue to be strong and gusty
afterwards. Winds will begin to shift out of the SW the W late
evening thru morning. VFR to MVFR cigs expected at the end of the
period.

&&

.PREV DISCUSSION... /issued 240 PM CST Thu Dec 31 2020/

DISCUSSION...
Low pressure continues to deepen and lift to the north across East
Texas this afternoon. The cold front so far that slipped into the
northern portions of the forecast area this morning has been
stubborn to lift back to the north. However this is still expected
to happen as the low lifts to the north and warm sector surges
inland. So far storms have been rather tame, however some areas of
heavier rain has fallen across the area with almost 5 inches of
rain in Hardin County.

Still potential is still there for a few severe thunderstorms
mainly to the east of the Sabine river this afternoon and evening
before ending from west to east this evening into the overnight.

Still expecting cooler and drier conditions to work in behind the
front into the weekend with a gradual warming trend into the
middle of next week.

The next system around Wednesday into Thursday now has a few
timing differences in the guidance compared to yesterday but will
continue to carry chance POPs during that period.

MARINE...
Winds will continue across the coastal waters through the night
initially from the Southeast then shift to the west.
