An approaching cold front will interact with the more moist air Wednesday evening – storms and some locally heavy rainfall is possible.There is over 2″ of moisture evaporated into the atmosphere by Wednesday afternoon a key component to producing heavy rainfall totals. I do not see wide-spread flooding Wednesday with the current set up but under a t-storm or at least a series of them high amounts may occur. A Flash flood watch has been hoisted.
The average rainfall off 6 computers places 1.50″ of rain down in the city. The spread runs from 1.06″ to 1.98″ but again it is important to note the amounts will vary widely in and around t-storms. I’m posting the 26 computer average rainfall off the NWS SREF computer suite below.
