The primary weather concern for this forecast will be the severe
weather threat Wednesday. Otherwise, significant weather impacts
are generally not expected as we go through this week and into the
weekend.
Today through Tuesday night: Low level ridging over the southeast
CONUS will continue to keep things hotter than normal in the near
term. Given hot and unstable conditions and a subtle upper level
shortwave trough crossing the region, scattered showers and a few
storms will develop again later this afternoon, and a stray storm
or two may briefly become strong to severe. For Tuesday into Tue
night, the ridge is forecast to intensify some ahead of an
approaching trough, and the increased anticyclonic flow and
subsidence should help to suppress convective rainfall.
Wednesday: There is a marginal risk for severe storms for the
entire area beginning early Wednesday morning and lasting through
the afternoon. A shortwave trough will amplify and dig southward
in the Mississippi Valley region Wednesday. As this happens and
deep layer flow increases, a developing surface wave and
strengthening warm sector will lower pressures over the forecast
area. This will result in the threat for an organized convective
system to move into northwest portions by as early as daybreak
with damaging straight line wind hail up to quarter size being the
main hazards. The convective system will then move across the
remainder of the area Wednesday afternoon, possibly reorganizing
and intensifying during the time of peak heating and
destabilization over eastern/southern MS.
Late week through the weekend: Going into Wednesday night and
Thursday, the threat for severe weather will end, but persistent
cyclonic flow associated with trough passage will support
additional rainfall. The trough will shift east and be followed by
dry and milder air as we go into the weekend. Temperatures will
be near typical values for late September. /EC/
