Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
921 AM EDT Thursday, May 24, 2012
...HYDROMETEOROLOGICAL DISCUSSION...
Showers and storms will once again develop later today in the southeast
Ohio Valley, tapering off shortly after sunset this evening. Focus then shifts
to a weak cold front dropping into the basin late tonight and Friday. This
boundary should trigger scattered convection across basin, particularly
during the afternoon hours Friday. The front will then lift northward as a
warm front this weekend, ushering in the warmest airmass of the year thus far.
Another cold front will move into the basin Monday night and Tuesday,
bringing another round of showers and storms along with a return to near
normal temperatures.
...FLOOD POTENTIAL DISCUSSION...
The flood potential will remain low this week and into early next week.
