Why it was so much warmer in Oshkosh yesterday

September 5th, 2013 at 6:14 am by under News, Weather

There were big temperature differences in the area yesterday as a cold front sunk from north to south during the day.  That meant cooler temps north and warmer south.  In Green Bay it was 72° but in Oshkosh the high reached 81°. Check out the map below.  A closer look at hourly temperatures shows that Green Bay hit that high of 72 at 11 am while Oshkosh hung on to the heat until about 3 pm before the cold front pushed to the south and brought in northeast winds.

It’s a cool morning as the kids head to the bus stop but temperatures will warm to near 73° by the time they head home.

The normal high for this time of year is 74° and we’ll be near normal with an area of high pressure bringing abundant sunshine today.  A warm up to near 83 is expected tomorrow.


Record-Breaking Cold July Weekend

July 29th, 2013 at 8:55 am by under News, Weather

It sure was a cold July weekend.  The highs Saturday and Sunday were in the upper 50s to low 60s.  Record cold maximum temperatures were set in many locations including Green Bay, Appleton and Oshkosh.  If it felt like fall to you that’s because these temperatures are “normal” for early October!

Here’s something you don’t see every day…it was much warmer in Alaska than it was around here in July.  The cold and clouds, the result of a big upper-level low pressure area spinning to the north over the weekend,  brought colder than normal temperatures to much of the region.  In fact the 75 degrees you see in northern Alaska is a place called Arctic Valley.  Yes we were colder than Arctic Valley, Alaska!

Stormy Monday 072213

July 23rd, 2013 at 5:42 am by under News, Weather

Thunderstorms rumbled through the area Monday evening creating quite a light show but not much damage.  Storm reports included 1.5″ hail in Summit Lake (Langlade County); 1″ hail in Bryant (Landglade County) and wind damage in Menominee county where trees were downed on Highway 55 north of County Road M.  There was also 1″ hail seen in Abrams.

The same storm system produced a tornado near La Crosse.  A tornado was confirmed by media and emergency management after 5 pm near Bluff Siding and was reported in Trempealeau Wildlife Refuge (Trempealeau County) at 5:20 where there were reports of a swath of trees damaged.  Check out the picture of the tornado taken from Winona, MN by John Redig.  The photo was posted on the National Weather Service website in La Crosse where there is much more information about the storms.

Record Dew Point in Green Bay

July 18th, 2013 at 12:26 pm by under News, Weather

The high humidity we’ve been experiencing with dew points in the mid 70s, got me wondering;  “what was the highest dew point ever recorded in Green Bay?”

Officially the answer is 83° on July 30, 1999.  Isn’t that unbelievable! I mean I’ve been suffering with the dew points in the 70s this week.  I can’t remember that particular day but according to records it happened at 3 pm and the temperature was 96° for a heat index value of 121° (I’m assuming I was inside with the  air conditioning on taking a nap which is probably why I don’t remember it)

The second place dew point temperature is 81° set on two days… July 13, 1995 when the high temperature reached a scorching 102° and the heat index topped out at 121°; and July 18, 2011 (Two years ago today) when the high temperature was 91° and the heat index reached 105°

As I said above, these are “official” statistics.  If you search the internet looking for the highest dew point ever in the United States you may come upon a story that has Appleton listed as one of the top dew points with 90° on July 13, 1995.  I put in a call to Jeff Last, the Warning Coordination Meteorologist at the National Weather Service in Green Bay the other day  and asked him about it because it sure sounded high to me.  He explained that it was indeed an “un-official” measurement because the Appleton site has a surface weather observing station called an AWOS (Automated Weather Observing System) as opposed to an ASOS (Automated Surface Observing System) for Green Bay.  The ASOS is maintained and calibrated more often and is official National Weather Service equipment.  The AWOS information is used for records at times by the NWS but when the data is compared to other nearby sites and deemed unreliable then it is not considered official.  The 90° dew point is probably much too high for that particular day and time especially considering the dew point in Green Bay at that time (5pm) was 79°.

Now that sure was a long-winded explanation but unlike the weather this week, I don’t think it’s just a lot of hot air.

Fourth Forecast…not as hot as last year

July 2nd, 2013 at 11:47 am by under News, Weather

It was a hot Independence Day last year – 95°  and almost a record!  This year we can expect more normal temperatures.  Right now it looks like a 30% chance of showers Thursday otherwise partly sunny skies and a high near 78°.  Although the humidity levels will be creeping up a bit, the dewpoints should stay around 58° which is not that bad.

At Fireworks time temperature will be near 70° with partly cloudy skies.

Ingredients are here for severe storms later today

There is a slight risk (area in yellow) for severe storms from Green Bay, through the Fox Cities, and into Southern Wisconsin.  The primary threat from storms today will be large hail and damaging winds.

Scattered thunderstorms will develop early this afternoon (1pm) in Southwest Wisconsin.  These storms will race north into parts of NE Wisconsin today. 

The ingredients for severe weather include a strong jet stream and warm air at 4 thousand feet moving from Iowa into Wisconsin.  The jet and warm air will cause lift creating the storms.

The storm will also feed off of high humidity that is located on top of us.  We just need more sunshine to warm the air for the atmosphere to become conducive for severe storms. 

The Fox11 weather team will keep a close eye on our skies today, stay tuned!

Record Heat Tuesday

May 15th, 2013 at 9:06 am by under News, Weather

Wow it was HOT yesterday in the region with temperatures reaching the triple digits in many locations in Nebraska, Iowa and Minnesota.  Minneapolis hit 98° and Sioux City, Iowa reached 106° which is the highest temperature ever for the month of May.

That hot weather impacted the western portion of Wisconsin as well with highs in the low 90s in Eau Claire and La Crosse.

It’ll be a beautiful day today with another tomorrow and right now the Marathon weekend in Green Bay looks nice too.  We’ll be updating the all-important  Sunday morning forecast frequently until race time.  Enjoy the day!


Drowning danger high for area rivers

April 19th, 2013 at 9:24 am by under Weather

The threat for drowning is high with rivers running fast and cold across NE Wisconsin.  Remind your children to stay away from these rivers; they are not a good place to play.

Precipitation amounts will be light Friday, and dry Saturday and the first half of Sunday.  This is good news as we won’t add much runoff to area rivers, so don’t expect any big changes in water levels through the weekend. 

Half of the rivers in NE Wisconsin are below flood stage, the other half are near their banks.  The Fox River in Berlin is the only one reported in flood stage.  The Fox River in Berlin is expected to rise slightly today before slowly falling Monday
