National Weather Service Hazardous Weather Outlook issued 453 am March 14
Hazardous weather outlook for north central and northwest Ohio.
Strong to severe thunderstorms are expected to develop across the region today. The best timing for these stronger storms will be this evening, or roughly, from 6 PM to 11 PM. The main threat with any storms will be large hail, greater than one inch in diameter. Some storms could generate a damaging wind threat and a tornado could also be possible. For that, these counties are in a Slight Risk of severe weather from the Storm Prediction Center.
Impacting Hancock-Seneca-Wyandot-Crawford-Richland-Marion-Morrow-Knox Counties.
Streamflow Situation provisional data supplied by USGS
Streamflows ratings have tilted below normal through central Ohio Thursday. A quick look at the streamflow map of Ohio appears two-thirds normal and one-third below normal. Indeed upon counting, the number of below normal stations has doubled overnight, 39 locations (up from twenty stations yesterday and just seven on Tuesday) rated below normal Thursday, impacting both sides of the divide.
For Lake Erie drainage basin, the streams and rivers are an even mix of normal and below normal.
South of the state divide, the major downshift in streamflows is showing up most prominently in the Scioto basin. The Scioto River matches flow ratings today with tributaries Olentangy River and Alum Creek, all with the majority of upper basin monitors recording below normal flow levels. Continuing the trend observed yesterday, the greatest change from normal to below normal ratings is in the upper basins, including the headwater drainage areas of the Upper Ohio minor tributaries, the Muskingum basin and the Scioto basin. In the west, the Great Miami River is still flowing normal with two stations below normal, doubling from the one yesterday at Sevenmile Creek at Camden.
As of this report, there are no extreme high or low flows or active floodings recorded.
Drought Map USGS 7-day average streamflow against seasonal average
St Josephs River watershed remains the one part of Ohio on the drought map Thursday. The down-shift in streamflows will send more area to the drought map as 7-day averages drop below seasonal normal. More to follow.
Harmful Algal Blooms - Lake Erie HAB from National Centers for Coastal Ocean Science (NCCOS) satellite monitoring program
The latest image from NCCOS was captured March 13 at a surface wind speed 14.5 mph. The image is partially cloud obscured. No HAB activity is visible in this image. The wind speed is still too high for a reliable estimate of the extent of any HAB we see. Likewise, we cannot be certain where HAB is not visible that it is not submerged out of view.
Localized HABs appeared in the last image, March 12, showing up along the Michigan shore near Monroe, matching 100 thousand cells per 100 ml.
Drinking Water Advisories
City of Logan announced a boil order for North Wood and North Glenwood Drive customers following water main and fire hydrant repairs on Monday. City of Logan serves a resident population of 6704 from a groundwater source in the Hocking River watershed, Hocking County.

USGS Provisional Data Statement
Data are provisional and subject to revision until they have been thoroughly reviewed and received final approval. Current condition data relayed by satellite or other telemetry are automatically screened to not display improbable values until they can be verified.
Provisional data may be inaccurate due to instrument malfunctions or physical changes at the measurement site. Subsequent review based on field inspections and measurements may result in significant revisions to the data.
Data users are cautioned to consider carefully the provisional nature of the information before using it for decisions that concern personal or public safety or the conduct of business that involves substantial monetary or operational consequences. Information concerning the accuracy and appropriate uses of these data or concerning other hydrologic data may be obtained from the USGS.
