AREA FORECAST DISCUSSION

1101 AM EST Sun Dec 14 2014
.Near Term [Through Today]...
Another sunny, dry day is in store with deep ridging centered over
the Southeast. The 12Z Tallahassee sounding showed a very shallow
layer of higher RH near the surface associated with a strong
inversion. The atmosphere aloft was much drier, and the dewpoints
should mix out late this morning or this afternoon, similar to
yesterday. Only minor tweaks were made to the existing forecast.
.Prev Discussion [417 AM EST]...
.Short Term [Tonight Through Tuesday]...
High pressure will be centered just north of the forecast area
tonight. This will allow for another chilly night with lows Monday
morning dropping into the low to mid 30s. By Monday, the pattern
will be in transition as high pressure moves off the East Coast
and a storm system moves across the Plains. Little in the way of
return moisture or even deep layer forcing with this storm system
will keep rain chances very low Monday night into Tuesday. High
temperatures Monday and Tuesday will finally return to above
normal values, and possibly exceed 70 degrees in a few areas.
.Long Term [Tuesday Night Through Sunday]...
In the wake of a mainly dry cold front on Tuesday afternoon,
cooler and drier air will return to the region by the middle of
the week. Model guidance continues to remain in good agreement
that Wed-Thurs should be under the control of high pressure with
slightly below normal temperatures each day. By Friday, the models
begin to diverge with a more energetic 14/00z Euro indicating a
higher amplitude trough moving across the Central and Southern
Plains leading to strong surface cyclogenesis across the Western
Gulf. The 14/00z GFS has a similar pattern - though weaker
solution. While it`s too early to speculate about strong storms,
both models seem to suggest that rain chances will be increasing
late Friday and into Saturday. Thereafter, considerable
uncertainty abounds. Maintained a forecast a little closer to
climatology for the end of the period, though cooler conditions
could be in the offering if the Euro were to verify.
[Through 12Z Monday] VFR conditions are expected to prevail through
the period with light winds.
Northwest winds will weaken later today as high pressure moves
near the marine area. On Monday, winds will shift to the south
ahead of an approaching cold front. On Tuesday, a cold front will
pass through the northeast Gulf and will increase winds to
moderate levels. High pressure will move in behind this front,
resulting in light winds and low seas for the remainder of the
Fair weather will continue through Monday, with a gradual warming
and moistening trend, especially during the afternoons. With a high
pressure system remaining in place, surface and transport winds, as
well as daytime mixing heights, will remain low. This combination
will keep daytime dispersion values at unusually low levels.
With generally dry weather expected through the next several days,
rivers will remain well below flood stage.
