The area burn scar locations and normally dry washes will be most susceptible to impacts. DISCUSSION...Convective initiation is well underway across the high country of southern CO and down into northern NM, with locally heavy shower and thunderstorm activity in particular beginning to focus over and near the Sangre De Cristo Range. MLCAPE values along the CO/NM border have locally increased to over 1000 J/kg and this coupled with deeper layer concentrations of monsoonal moisture and orographic ascent near the terrain should favor an additional expansion of convection over the next several hours. Facilitating some of the convective potential today will also be proximity of a well-defined mid-level vort center over northwest NM which should drift slowly off to the east over the next several hours. This energy coupled with the orographic nature of the convection may foster some smaller scale enhancement to the convection with locally enhanced rainfall totals. Rainfall rates of as much as 1 to 2 inches/hour are generally expected with the stronger convective cells, and with relatively slow cell-motions, there may be some totals by early this evening of 2 to 3+ inches. These rains will foster concerns for isolated to scattered areas of flash flooding, and primarily involving the more sensitive burn scar locations and normally dry washes.
