Areas affected...Portions of central and northern Arkansas

Concerning...Heavy snow=20

Valid 112244Z - 120145Z

SUMMARY...Though localized, mesoscale snow bands will continue this
evening and be capable of producing snowfall rates near to just
above 1 inch and hour in parts of central and northern Arkansas.
Some of this activity may reach into parts of southern Arkansas
later this evening as temperatures cool below freezing eventually.

DISCUSSION...KLZK radar imagery shows highly banded reflectivity
structures. The strongest of these bands have shown 30-35 dBZ echoes
and have produced heavy snow reports from west-central Arkansas into northeastern Arkansas. This region will stay within favorable
mid-level frontogentic zone as well as within the right entrance of
the upper level jet for the next 3-4 hours. These mesoscale bands
can be expected to continue this evening leading to the potential
for heavy, but localized, snowfall rates. Warmer temperatures exist
in southern Arkansas, but continued cold air advection and diabatic
cooling from precipitation should lead to a change over to snow and
potentially similar banding later this evening.

Areas affected...much of Arkansas...northern Louisiana...and western Mississippi

Concerning...Tornado Watch 57...

Valid 030506Z - 030600Z

The severe weather threat for Tornado Watch 57 continues.

SUMMARY...Local risk for damaging winds and a tornado or two
continue across WW 57. With risk expected to continue -- and even
increase overnight, a new Tornado Watch will be issued as the
existing watch is set to expire at 03/06Z.

DISCUSSION...Latest radar continues to show a locally
vigorous/complex convective band moving eastward across western
Arkansas, the Arklatex, and southeastern Texas at this time.

The band continues to weaken across southeastern Texas, but farther
north, locally damaging winds and an isolated tornado or two remain
possible in the short term.

With time, as the upper system shifts across Texas and gradually
takes on a more negative tilt overnight, cyclogenesis in the
southwestern Arkansas area will continue, with a corresponding
increase in low-level theta-e advection, beneath gradually
strengthening flow aloft. As such, severe/tornado risk is expected
to likewise increase, and last through the overnight hours and
through sunrise. As such, with WW 57 set to expire at 03/06Z, a new
tornado watch will be issued within the next half hour or so.

Areas affected...Central Indiana into west-central Ohio

Concerning...Tornado Watch 44...

Valid 142228Z - 150000Z

The severe weather threat for Tornado Watch 44 continues.

SUMMARY...Large/very-large hail will remain the primary threat with
ongoing storms. The tornado threat may increase early this evening
conditional on storms remaining discrete.

DISCUSSION...Storm coverage has continued to increase in central
Indiana into west-central Ohio. These discrete storms will continue
to be capable of large/very-large (1.5-2.5 in.) hail given the
strong deep-layer shear and steep mid-level lapse rates. Low-level
shear is not overly strong as surface flow remains rather veered.
However, there is an expected increase in the low-level jet within
the mid/upper Ohio Valley this evening. This 850 mb flow will also
be veered, but storms that can remain discrete into the early
evening may pose an increased risk of a tornado.
