.DISCUSSION...

Today and Tonight:

Quiet weather conditions are expected for the short term. Following
yesterday`s frontal passage, high pressure at the surface will slide
south and east into our area today. This will keep dry weather in
the forecast. Temperatures today will be just about what is normal
for late January with highs ranging from the lower 50s in the north
to around 60 in the south. With clear skies and light northerly
winds, cooler conditions will occur tonight. Overnight lows will drop
into the lower to mid 30s areawide. /28/

Wednesday through Monday:

The main period of note through the remainder of the forecast will
be Friday through Sunday of this upcoming weekend. Before then,
quiet and seasonable weather is expected under progressive flow
aloft. Then models indicate a shortwave moving east across the
country with varying levels of depth. The GFS continues with a
lower amplitude, quick-moving system over the northern CONUS. A
weak cold front would dip into our region with a chance for light
rain in this scenario. The ECMWF and CMC on the other hand
indicate the shortwave energy will tighten up and deepen over the
Ohio River Valley, with a developing surface low tracking
generally from the Gulf Coast toward New England on Sunday and
stronger cold front moving through in its wake. Given some
uncertainty, did not go fully with ECMWF- like scenario. But did
generally favor ECMWF for overall timing of the system and
associated forecast elements. With these uncertainties, confidence
decreases for the beginning of next week, but certainly the
potential exists for at least a light freeze on several nights
next week. Also, if a more robust surface low does develop around
the region, rainfall amounts of 1 to 2 inches are not out of the
question especially through the Pine Belt and areas south of I-20.
