Combination of RRQ upper divg/minor impulses/moisture rich
environment contributing to scattered TSRA extending from the CWA
swwd into KS and all the way down into the TX panhandle.
Persistent pcpn over the last several hours had prompted issuance
of several Flash Flood Warnings last evening. And with additional
pcpn expected this morning...will maintain Flash Flood Watch along
south of I-80 corridor until early this afternoon . The RAP13 is
showing several boundaries in place in the vicinity of the CWA
this afternoon...any of which could be the focus for TSRA
initiation as environment becomes more unstable...MUCAPEs
2000j/kg. Therefore will opt for high-end chance POPs. Later
tonight...pcpn chances will decrease from north to south rapidly
after midnight as a drier air mass invades from the north. Wed
aftn thru Thursday night...dry conditions continue as best
moisture will be found to the south.
