Today and Tonight...Troughing aloft, with its axis east of the Lower
Mississippi River Valley, encompasses nearly the entire eastern half
of the United States.  The resulting northwest flow aloft across the
region and northeast surface winds circulating around a surface high
centered over the Great Lakes region, will continue to promote a
drier airmass and below normal conditions across the forecast area
today into tonight.  Dew points this afternoon will mix into the
upper 40s to upper 50s across the area, as highs top out in the low
to middle 80s under mostly sunny skies.  Another very pleasant late
summer evening is then on tap as lows range from the middle 50s to
middle 60s tonight. /19/
Tuesday through the Weekend...At the risk of sounding like a
broken record on repeat, the remainder of the extended period will
remain generally quiet Tuesday through Thursday. Global guidance
continues to show mid/upper level troughing beginning to slowly
slide east across the area through Thursday evening. This will
allow for ridging aloft to gradually build into the region from
the west. Regarding the rain chances, portions of southeast MS
could see a slight chance of scattered showers by Tuesday
afternoon, with afternoon PoPs between 15-25%. Ridging aloft will
continue across our CWA Friday with afternoon highs peaking into
the low 90s areawide. Quiet conditions will persist through the
weekend. /CR/
