Morning showers and clouds have dissipated, but the morning

am temperatures are only in the middle 70s across much of North
Mississippi, but are in the low to middle 80s across most of the
remainder of the Midsouth. Knocked afternoon highs down a couple
of degrees in North Mississippi, around 88 degrees. The remainder
of the Midsouth should climb into the low 90s. Another round of
showers and thunderstorms are expected this afternoon.

.DISCUSSION... /issued 634 AM CDT Wed May 30 2018/

Skies are cloudy over eastern sections of the forecast area with
mostly clear skies elsewhere. Temperatures early this morning are
in the lower 70s. The center of Alberto is currently over far
Western Kentucky and moving north. Some of the rain bands from
Alberto continue to effect northern sections of West Tennessee.
The rain bands should move out of Tennessee later this morning so
will keep the Flash Flood Watch in effect until 7 AM with no need
to extend it.

With Alberto moving out of the region, the weather pattern should
return to a more summer like one with scattered afternoon and
early evening thunderstorms. Temperatures will be warmer today
with highs around 90 degrees. On Thursday, a frontal boundary
will be over the Mid-Mississippi Valley. Scattered thunderstorms
are expected to develop ahead of the front and move toward the
forecast area. There could be some severe storms over northern
sections of West Tennessee and the Missouri bootheel with large
hail and damaging winds as the main threat. Temperatures will
remain quite warm on Thursday with highs in the lower 90s.
The cold front will move south Thursday night and Friday remaining
north of the forecast area with more thunderstorms expected.

The front is expected to die out before reaching the forecast area
Friday night so rain is not expected either Friday night or
Saturday. Another cold front will makes its way into the forecast
area for Saturday night and Sunday bringing more thunderstorms to
the region. Cooler air will move into the region on Sunday behind
the front bringing temperatures back to normal levels.

High pressure will build into the region by Sunday night bringing
somewhat drier air into the forecast area. Dry weather and near
normal temperatures are expected from Sunday night through
Tuesday.
