.PREV DISCUSSION... /issued 358 PM CDT Fri Aug 2 2019/ 

DISCUSSION...
As for tonight into tomorrow, patchy storms are expected to
persist near the MS/AL line and parts of western Tennessee. With 
these storms the primary threat will be heavy rainfall and 
lighting. As for the rest of the forecast area, expect dry 
conditions with temperatures dropping to the lower 70s tonight 
with partly cloudy skies.

Northwest flow will remain in place for the next several days,
with broad trough to our east being our rainmaker for the 
weekend. The frontal boundary currently located on the MS/AL will 
shift south placing northern Mississippi in the area with the 
greatest potential for thunderstorm development for the rest of
the weekend.

High pressure will build back into the area Monday night bringing 
another period pleasant weather. Our rain chances for early next 
week will be driven by daytime heating with primary threats of 
heavy rainfall and lightning. The Mid-South will likely see a 
lower percent of thunderstorm coverage for until Wednesday. As for
Wednesday rain chances increase due to a trough moving into the 
area. Highs will be in the lower 90s for the remainder of the 
forecast.

TN Valley into northeast MS where rain fell this afternoon.
Prevailing visibility in this areas is currently expected to

Conditions will improve by 13-14z with a diurnal Cu field
