Wow what a difference 10 days makes! In the middle of the month we were keeping track in the weather office of driest Julys in Green Bay thinking we were headed for a record-breaker. Just 10 days later we are more than 2.5″ above normal for the month. That really helps the drought around here. Unfortunately that hasn’t been the situation in all of the viewing area. Even though there has been at least a little rain to the south, it’s still not nearly enough for Green Lake and parts of Winnebago county. Check out the before and after pictures Director Greg Bins took of the Eureka lock. Overflowing in May but sitting low now. Rain will end this afternoon and it should be a dry and beautiful weekend. ..beautiful that is for those who got the rain. It’s all relative isn’t it.
We set and tied some record highs yesterday with 100° in Oshkosh breaking a 72 year-old mark of 97°. The heat and humidity added up to heat indices in the 100s for much of northeast Wisconsin. A much more comfortable day is on tap with highs in the mid 80s and dew points in the low 60s. (Green Bay recorded a dew point of 76°yesterday, ugh!) So today we have relief from the heat and tonight we may be getting some relief from the drought. Showers and thunderstorms are likely overnight and into tomorrow morning with heavy rain at times. We also have a chance for more rain Thursday and Sunday.
Relief is coming our way tomorrow as a cold front sinks from north to south today through the area. After a high in the low 90s today, cooler and less humid air will greet us tomorrow with a high near 84. Of course we’re also looking at some help for the dry conditions in much of the region and that front will touch off scattered showers and thunderstorms this afternoon into tonight. With the “scattered” nature of these storms, some of us will receive much-needed rain while others will continue to deal with brown grass. The good news is that there’s another chance of rain tomorrow night into Thursday morning. The 98° reached in Green Bay yesterday was the 20th 90° day so far in 2012 which places it in the top 5 all-time. It wasn’t a record though for Titletown as the record of 100° was set in 1931. A record was set however in Manitowoc of 97° and tied in Sturgeon Bay (also 97).
Southern Wisconsin has been upgraded to Severe Drought Levels. The cities of Madison and Milwaukee are in the severe drought zone. When experiencing Severe Drought water levels in rivers will be low, wells may dry up, crops loss is likely, and the fire danger is very high.
Moderate drought has pushed north into Green Lake, Fond du Lac and Waushara counties.
Abnormally dry conditions have moved north of Green Bay into southern Oconto and southern Door Counties.
While there is some rain in the forecast this weekend it won’t be enough to alleviate the dry/drought conditions across the state.
We’ve been sweltering under this heat for 7 days now but we’ll get some relief tomorrow. Since Saturday June 30th highs have been 90 or above in Green Bay (and for 9 of the last 10 days). It’s not only the heat as they say…it’s the humidity. Very humid conditions have resulted in heat indices in the 100 degree and above range. A cold front will push through the state tonight and we’ll wake up to much more comfortable conditions; lower humidity and cooler temps. The front may touch off some strong or severe thunderstorms tonight with damaging wind and large hail the main threats. Highs for the weekend will be a more normal 80°.
Numerous records were set around the state yesterday as highs reached the century mark in some places. The 99° in Green Bay was the hottest since 1995, the last time we’ve seen triple-digits. We also saw a dew point of 78° on 2 days, July 4th and 5th which is very unusual and the heat index reached 110° on the 4th and 109° on the 5th. But remember around here we spell relief…S-a-t-u-r-d-a-y.
One hundred degree temperatures have happended only 17 times since 1896, and 10 of those occurred in 1930s (The Dust Bowl).
The hottest temperature ever recorded in Green Bay was 104° on July 13, 1936.
The most consecutive 100 degree days were four in 1936.
The last time Green Bay’s temperature has reached the century mark was July 14, 1995 when we hit 102°.
