...New AVIATION...

.SYNOPSIS...
Issued at 311 PM CDT Mon May 15 2023

Scattered thunderstorms are ongoing across portions of the Mid
South this afternoon. These storms may produce strong winds, locally
heavy rainfall, and small hail. Rain chances will increase on
Tuesday, ahead of an upper level disturbance and surface cold
front.

&&

.DISCUSSION...
(This evening through next Sunday)
Issued at 311 PM CDT Mon May 15 2023

Most of the afternoon/evening convection is slowly moving out of
the area. We could still see some other development this evening.
Rain chances will increase for tomorrow as a cold front is
expected to move through the region. This will increase the
coverage and intensity of storms. We do not expect any severe
weather with this passage. A shortwave trough will drop
southeast from the Ozarks on Wednesday, likely aiding convection
over southern and and central MS on Wednesday. A few storms may
extend into north MS Wednesday afternoon. Much cooler temperatures
are expected the remainder of the week as highs dip into the 70s
and 80s. Expect dry conditions through Friday before another front
impacts the area this weekend. Another round of showers and storms
are possible Friday into Saturday morning. Another pleasant and
cool weekend is expected.

&&

.AVIATION...
(00Z TAFS)
Issued at 624 PM CDT Mon May 15 2023

Mostly VFR conditions through the TAF set. VCTS this evening and
again tomorrow afternoon/evening could cause some MVFR vsbys. Wind
is generally SSW, however outflows from storms could cause
direction to be rather variable. Wind may gust up to 20kts
tomorrow afternoon and with any storms. Once the cold front comes
through expect the wind to veer more northerly by the end of the
TAF cycle.
