.DISCUSSION...

Quiet weather is set to continue for the next several days with
an abundance of relatively dry air through the column associated
with deep-layer ridging. Widespread high temperatures in the low
to mid 90s will continue with readings on the high end of model
guidance due to the ongoing drought.

Will introduce small rain chances in the southern and eastern
counties beginning on Sunday due to a modest increase in PWATs as
weak southeasterly flow develops. The general upward trend in
moisture and rain chances will continue into the upcoming week
with models indicating a large trough developing across the
Plains. This should cause low-level moisture advection as
southerly flow strengthens across the region. There is large
disagreement regarding the timing and evolution of the trough and
associated cold front, but a frontal passage seems probable around
Tuesday/Wednesday along with much higher rain chances.
