Overview of Significant Weather

Convective clusters situated in moist easterly flow persist throughout evening (0000 - 0600 UTC 2 July) in eastern Colorado. These clusters merge and evolve into a well organized squall line with stratiform precipitation over western and central Kansas overnight. This MCS subsequently merges with an area of less organized convection over northern Oklahoma near sunrise (around 1000-1200 UTC). An MCV is evident in the aftermath of the decayed squall line convection over central/eastern Kansas. Convective activity persists somewhat longer (past sunrise) along the southern portion of the merged system. By midmorning (1500 UTC 2 July) visible satellite imagery indicates an outflow boundary moving southeastward from an active convective cluster in northeastern Oklahoma. This outflow becomes the focus for an afternoon convective system over Arkansas back into southeastern OKlahoma. This secondary MCS dissipates during the early evening (after 0000 UTC 3 July) in the environment of weak vertical wind shear. During the day the MCV farther to the north persists while moving slowly eastward into Missouri. A first the MCV is relatively inert producing only light precipitation during the afternoon and early evening. However, a small cluster of convection that forms around midnight near the MCV center in central Missouri (around 0400-0500 UTC 3 July) is remarkably long-lived, persisting through the following morning as it moves southeastward into Kentucky and Tennessee.
