June 02

Cincinnati 5NW #13 (Hamilton County) Ronald E. Rothhaas Jr. - June saw a significant change over the spring pattern, with an end to the wet and cold regime and significant dry weather in many areas by month's end. While temperatures were only slightly above normal, the rainfall was very spotty after a wet start. While rainfall here was well above normal, this was the result of direct hits by scatterred downpours which consistently missed many locations. At least half of the area had little or no rain in the last half of the month. Scattered slow moving thunderstorms on the 25th produced isolated totals of 2 to 4 inches in an hour or two resulting in local flash flooding.

Cleves 3NW #55 (Hamilton County) James F Davis - June averaged out 2.2 degrees above mormal.My average max was my second highest since 1987.

Lagrange 2SW #87 (Lorain County) James Shedron - I have measured only .05" precipitation from June 15th to the end of the month!

Ravenna 1E #101 (Portage County) Rich Rabatin - I also had 7 thunder days along with 1 WATCH DAY & 3 WARNING DAYS.

Streetsboro 2N (Portage County) Vance Lunn - June was quite wet up to the 18th with three days seeing one inch or more per day. The 19th-30th was dry with some light rain only during the period of the 26th-28th. Five days saw 90 plus temperatures, but many mornings and a few afternoons were cool with the afternoon high temperature of the 6th reaching only 59 F. Other weather: 4 days with thunder, and 6 days with fog.

Ottawa 4E #15 (Putnam County) Phil & Bonnie Higley - Been a very dry month & Very warm toward the end.

Wooster 7N #16 (Wayne County) Jack Sisler - It was drier and warmer than normal for the month of June. Mean temperatures were about three degrees above normal with three 90+ degree maximum temperatures during the last week of the month. Precipitation was about one inch below normal although it didn't start out that way. I had 1.5" of rain during the first week which was a little more than half of the monthly total. I had no rainfall during the last nine days of the month with only .18" during the last thirteen days although there were thunderstorms in the area. Grassy areas were beginning to brown-out by the end of the month. I had up to one inch (quarter size) hail during a thunderstorm that went through on the evening of the fourth. You could hear the hail hitting the metal roofs of a barn and outbuildings 300 yards away as it was approaching. There was no high winds associated with the storm.

Subject: Severe Storms on May 31

All:

One of the hazards of issuing severe thunderstorm/tornado warnings under the county-by-county system is that in most cases damage is very isolated. One may have had no indication of severe weather at your location yet around the next corner there could be trees downed or structural damage. This inevitably leads to most people in the county thinking that the warning was not necessary since they are not aware of damage. Of course on occasion there is a big blow and the damage is significant or widespread enough and it makes the news.

We (the NWS) often have little idea of how widespread the damage may be when
we issue a warning. Also, in many cases we have to issue for a storm that is in one corner of the county or on the county line so it will likely not impact much of the county anyway. We have done some in-house experiments in trying
to warn for specific sections of counties but we had many failures because in a lot of cases new storms would develop on the outflow or flanking line and cause damage in a different part of the county than we originally thought. Since the counties are relatively small in Ohio we are still on a county scale.

Looks like another active week coming up. Enjoy.

Anyway, We have done some in-house experiments in trying to warn for specific sections of counties but we had many failures because in a lot of cases new storms would develop on the outflow or flanking line and cause damage in a different part of the county than we originally thought. Since the counties are relatively small in Ohio we are still on a county scale.

Another issue is defining the parts of a county... Exactly what consists of
"Northwest Wood Co."? The exception I see is Lucas, since many times cells
can come in off the lake over the extreme eastern sliver, yet a warning is
issued for all of the county -- including locations west of Toledo some 10+
miles away which, will certainly not be affected? Detroit used to do partial
warnings until Frankenmuth was hit by a tornado after they'd issued for a
different part of the county.

I had one inch hail during a thunderstorm that went through about 8pm Wednesday night. There was a warning on the storm but quickly died after it went east of the area. There were no high winds with the storm. You could hear the hail hitting the metal roofs of a barn and outbuildings 300 yards away as it was approaching.

See the picture in the Photos section under "WX PICS" folder. If you look at Gary's satellite picture taken at 7:40pm you can see the storm approaching the area.

Subject: Re: Flood Warnings

The National Weather Service in Cleveland no longer issues "Urban and Small
Stream Flood Warnings" although I think some offices still might. There was quite a bit of confusion about what constituted an urban/small stream flood and a flash flood. For instance, can one have an urban and small stream flood in a rural area that does not have a stream? And, when does a small stream flood become a flash flood? That being said, I wish we still had a vehicle to issue lesser flood warnings. We do so now by issuing flood statements but I am not sure how much dissemination they get. There is a product that some offices issue called a "Flood Advisory" that may be used here at some point in the future but the concern is that if someone dies or gets hurt during a flood advisory are we liable because it could have been considered a flash flood? To issue a warning, we have flash flood guidance for rainfall in headwater areas, 1, 3, 6, 12 hour rainfall guidance and plain old seat-of-the-pants criteria. Ugghh! Be careful out there.

Subject: Re: [OhioWx] Re: Flood Warnings

Jim and Group:

Thanks for your response to my previous question. I was always under the impression that flash flood warnings always pertained to the flooding of streams and rivers in situations where heavy rainfall within a short period could cause such waterways to quickly rise and cause an unexpected surge and/or flooding in some imminent manner. I can understand the difficulties in attempting to forecast any storm event, and after reading your explanation, especially in urban areas. It’s also unfortunate that NWS products have become the object of legal liability issues.

As an aside, as a City Planner and person who has been involved in urban development for over 20 years, I and my colleagues still struggle with attempting to provide adequate storm water controls in densely developed areas. Storm sewers are designed at a certain size in order to accommodate a rainfall that can be measured in quantity and related to a probability of occurrence over a period of time. Those of you who have to obtain flood insurance generally live in areas where a rainfall that happens once every 100 years would cause your local stream or river to reach flood stage and rise to the elevation that would cause your property (house) to flood. In reality, such flooding may be achieved with lesser storms depending on factors such as ground saturation, vegetation, hard surfacing and the adequacy or inadequacy of downstream drainage structures. I don't think that there is any perfect solution to designing drainage structures that can assure that we can avoid "urban flooding". While we could possibly oversize every structure built to accommodate the "Noah's Ark" type flood, such design and construction would be cost prohibitive. I guess in some ways, we have made Jim's job and that of the NWS more difficult.

Thanks for allowing me to get off on this tangent. I would be interested
to hear everyone else's thoughts on this issue.

We finally got a summer time thunder storm come though our area this even. But it
only drop 0.01" of rain fall. But it did kick the power off and then it come back on right away. As I look back a year ago, we had a Hi temperature on this date of 83 degrees that was back in 01. But today we hit 92 degree's at 3:38 p.m. 2 hrs. & 35 minutes before we had our thundershower. Our weather net was up, but it wasn't long before it was back down again. The only reason that they call a weather net here was because of the fair. Which is going on this week. I see worst storm come though the area before and the NET never was called. But nothing like this was going on. Is there anyone else out there that has the same problem? 4-E
