AREA FORECAST DISCUSSION

.Near Term [Through Tonight]...
This evening, a large and closed upper level low was centered over
Nebraska with a surface cold front well to the west of the local
area. Weak southerly flow at the surface veers to westerly aloft
with some passing high clouds. With a moist boundary layer and
weak surface winds in place, there could be some patchy fog across
the area tonight. Overnight low temperatures will generally be in
the upper 50s to near 60 across the area.
[Through 00z Wednesday] VFR conditions will prevail to start the
night. After 06z, patchy fog is expected to develop across the
area with the highest probabilities at VLD according to a
consensus of guidance. Fog is expected to lift quickly by mid-
morning with VFR conditions returning for the remainder of
.Prev Discussion [339 PM EST]...
.Short Term [Tuesday Through Wednesday Night]...
The NWP models are in good agreement in taking the large upper level
low (currently centered over WY) slowly eastward to a position
over upstate NY by Wednesday night. An associated cold front will
traverse our forecast area on Wednesday, accompanied by a chance
of rain and a return to more seasonal temperatures. The model
consensus forecasts poor low-level lapse rates and unspectacular
boundary layer dewpoints ahead of this front. Coupled with the
expected lack of more focused forcing, thunderstorms appear
.Long Term [Thursday Through Monday]...
The base of the aforementioned upper level trough will cut off
over AL by this weekend, while the surface cold front that passes
through our region on Wednesday stalls across the FL Peninsula.
While this will maintain upper level Q-G forcing across our
region, it appears that with the bulk of the deep layer moisture
to our south, PoPs will be 30% or less, and confined mainly to our
FL zones through next weekend. A more significant upper trough,
coupled with increasing deep layer moisture, will bring increasing
PoPs to most of our region on Monday. Although the large scale
weather pattern is not conducive for arctic intrusions, the decay
of the recent deep layer ridge over the Southeast will correlate
with a cool-down to near- average temperatures, with lows
generally from the mid 40s to mid 50s, and highs in the 60s.
With a weak high pressure ridge in place, light E-SE winds and low
seas will continue through Tuesday. A cold front will translate
southeastward across the coastal waters on Wednesday, with winds
shifting to the N behind the front. However, the stronger winds will
not arrive until Wednesday night and Thursday.
Hazardous fire weather conditions are not expected over the next
Most of the river stages were falling, and all were below flood
stage. We expect most of our region to get half an inch of rain or
less this week as the weak cold front moves through, which is
unlikely to significantly affect the river stages.
