Area forecast discussion, Jan 3, 5:20 AM CST, 7 minutes before

Area Forecast Discussion
National Weather Service Mobile AL
520 AM CST Fri Jan 3 2020

.NEAR TERM /Now Through Friday night/...Main concern through
tonight continues to be the threat of some localized flooding
generally east of a line stretching from just south of Camden in
AL to south of Leakesville in MS which includes all locations in
Northwest Florida. As a result a Limited Risk for flashing has
been posted in these areas which is now a county or two further to
the west the earlier anticipated. The best chance for Areal or
Flash Flooding to occur in the Risk area will be in urban
locations and areas with poor drainage. Rainfall totals of of 1 to
2 inches county wide with locally higher of 2 to 4 inches are
still possible. Stay tuned for further updates throughout the day
on this potential flooding situation.

As for severe weather a Marginal Risk also continues for locations
generally east of the I-65 corridor which includes all locations in
Northwest Florida. Most model guidance this morning continues to
show elevated values of vertical and directional shear to continue
across much of the eastern half of the forecast area through about
noon today. 0 to 3 km helicity values range from 100 to 200 m2/s2
along with bulk shear values ranging from 40 to 65 knots combined
with marginal surface based instability ranging 500 to 1000 j/kg can
be expected in the Risk area through this morning. Showers and
thunderstorms will continue to move mostly northeast at 25 to 30
knots through this afternoon.

In the Big picture a deep upper trof stretching from the northern
Plains to lower Tx and Mexico this morning will continue to shift
eastward stretching from the Great lakes to the lower MS River
valley by 12z Fri. Near the surface a cold front moving across the
forecast area early this morning will move east of the area by early
to mid afternoon with plenty of residual moisture in the wake of the
front mostly in the form of light to moderate rain and low clouds
through tonight and early Sat.

Temperatures will begin to lower in the wake of the front with highs
today still reaching the lower to middle 70s east of the front and
the middle to upper 60s to the west. Lows tonight will range from
the middle 40s to lower 50s to the west and the lower to middle 50s
to the east and along the coast. 32/ee

.SHORT TERM /Saturday Through Sunday night/...Upper level trough
will move eastward across the Tennessee Valley and central Gulf
Coast states on Saturday. Lingering moisture just ahead of this
system supports keeping a slight chance of rain in the forecast
early Saturday morning. A much drier airmass will otherwise be
ushered into our forecast area this weekend in the wake of the
passing trough and cold front. Highs Saturday and Sunday will
mostly range in the upper 50s to lower 60s, while lows Saturday
night fall into the lower to mid 30s over most locations north of
I-10 and in the upper 30s to lower 40s near the coast. Lows on
Sunday night will be slightly warmer in the upper 30s to lower
40s. /21

.LONG TERM /Monday Through Thursday/...Dry conditions prevail
Monday, with the next chance of rain arriving Monday night and
Tuesday with the next passing cold front. Conditions dry out again
for Wednesday and Wednesday night, with yet another approaching
system bringing back a chance of showers for Thursday and Thursday
night. Temperatures will be slightly above normal for Monday and
Tuesday, slightly cooler on Wednesday, then back to near to just
above normal for Thursday. /21

&&

.MARINE...Areas of dense fog will continue over the near shore waters
of Alabama and Northwest Florida early today ahead of a cold front
that will move across the region through this afternoon. A moderate
to occasionally strong southerly wind flow early today will shift
northwest then gradually build through early Saturday night. A light
to moderate southerly flow will redevelop Monday and continue
through early Tuesday ahead of another cold front approaching from
the west. A moderate to strong northerly flow is expected in the
wake of the front through midday Wednesday. 32/ee
