Dixie Delta
A few cities include: Greenville, Jonesboro and Memphis.
Terrain: Relatively flat with some trees; Mississippi River bisects.
Local tornado season: Peaks in April and May.
Road network: Manageable with a grid layout in many areas.
Radar coverage: Some gaps, especially near the Arklamiss area.
As is common in Dixie, the tornado season is relatively broad in this region. The peak tends to fall between mid-April and mid-May, but tornadoes are not unheard-of just about any time of the year. Most of the prominent tornado outbreaks in this region have occurred in spring and fall.
With some displacement from the Gulf of Mexico, there is a mixture of grungy, high precipitation storms and, occasionally, more classic supercells here. This is especially the case if an elevated mixed layer (EML) plume can advect into the area. Large hail is common and occasionally very large hail can occur. If storms grow upscale, extensive squall lines with damaging winds commonly affect the Dixie Delta area as well.
Terrain
The part of Dixie on either side of the Mississippi River is relatively flat. There is a lot of farmland in the area with a relatively low population density outside of the Memphis metropolitan area. As a result, it is relatively easy to have a good view of storms and watch them pass through.
There are some spotty forests and a few areas close to the Mississippi River that may be subject to flooding, but most of the region is conducive to storm chasing. Also keep an eye out for Mississippi River bridge crossings, as some stretches of the river may not have a bridge across for many miles.
Road network
Like the terrain, most of the road networks are also favorable for storm chasing in this area. A gridded road network makes up a good chunk of the Dixie Delta region, although there are some breaks in the road network to be mindful of. Roads in western Tennessee seem to be less favorable with more curvy, irregular byways, but with relatively flat terrain, it is still possible to storm chase there.
Interstate-40 bisects this region, generally, from west to east. Interstate-55 tracks northwest from Memphis into southeastern Missouri. The US-67/167 corridor in northeastern Arkansas is the approximate divider between hilly/forested terrain to the west and flatter, more chaser-friendly terrain to the east.
Radar coverage
For radar data, KNQA and KPAH cover northern parts of this area, including northeastern Arkansas, far northwestern Mississippi, western Tennessee, the Missouri bootheel and western Kentucky. KLZK offers some coverage for eastern Arkansas, but there is a glaring gap in radar coverage across southeastern Arkansas and adjacent Mississippi near Greenville.
In summary, if there is a good area in Dixie to storm chase, the delta region may be the best place to do it. The terrain is relatively flat and much of the area has a favorable road network to work with. The main limiting factor can be poor radar coverage, if chasing between southeastern Arkansas and parts of northwestern Mississippi.
