Hydrologic Outlook issued July 31 at 4:51PM EDT by NWS Indianapolis IN

Summary: ESFIND A slow moving low pressure system will impact central Indiana this weekend with widespread showers and scattered thunderstorms expected at times. Heavy rainfall will be possible due to efficient rainfall rates from repeated rounds of storms, primarily late tonight through Saturday night. Heavy rain may result in quick rises on streams or creeks and localized flash flooding. There remains some uncertainty regarding where the heaviest axis of rain will fall or exact rainfall totals. However, latest guidance generally favors northern portions of central Indiana. Some high resolution guidance suggest localized very heavy rainfall totals are possible, but varying solutions leads to lower confidence in issuing a Flood Watch at this time. Stay tuned for the latest forecast information. This outlook means that elevated water levels and potential impacts are possible, but not yet certain. Continue to closely monitor forecasts including the possibility of flood watches, warnings, and advisories.

Summary: ESFLOT A slow moving weather system will bring widespread showers, some heavy, to the area through Saturday.
