Discussion... 


Currently...the weak cold front has moved just south of the 
forecast area along with most of the showers. Skies are clearing 
out as drier air...dewpoints in the middle 60s...filters in on light 
northerly flow. Temperatures range from the upper 70s where clouds have 
hung on the longest to the middle 80s in Jonesboro. 


Tonight through Thursday night...upper level high pressure will 
start to build across the Southern Plains leaving the midsouth in 
weak northwest flow aloft. Surface high pressure will track across 
the Great Lakes and Ohio Valley. Surface winds will generally be 
northeast gradually shifting to the east with surface dewpoints in 
the 60s. Daytime highs will be in the lower 90s with lows in the 
60s to lower 70s in Memphis. Expect the weather to be rain free 
with a good deal of sunshine. Patchy fog is possible later 
tonight. 


It is not out of the question that upper level disturbances moving 
through the northwest flow aloft could produce a few showers and 
thunderstorms from Missouri into the midsouth during this period 
though not confident enough to mention at this point. Some 
shower/thunderstorm development is already occurring just north 
of the I-44 corridor in central Missouri this afternoon. However 
this activity should die with loss of heating this evening and it 
will be moving into a less favorable environment as it heads 
south. 


Friday through Tuesday...upper level high pressure will build over 
the region. Expect mostly rain free and seasonably warm conds 
with highs in the lower 90s and lows in the upper 60s to lower 
70s. Southeast winds will prevail Friday and Saturday with 
dewpoints remaining in the middle 60s. By Sunday into early next week 
winds turn more southerly with dewpoints climbing to around 70. 
This should allow for isolated afternoon showers and thunderstorms sun- 
Tuesday.

Current MVFR conditions at kmem and kmkl should improve to VFR 
levels by middle-afternoon with VFR conditions continuing at kjbr and 
ktup. A few showers continue to move over extreme southeast 
sections of the forecast area and should exit the region by late 
afternoon. Some areas of fog are expected to develop overnight 
which may produce MVFR visibilities. Winds will be northeast at 5 
to 10 knots this afternoon then become light northeast tonight.
