A Snowy Morning, More Is On The Way

Yet another clipper system slid through the region Monday night, producing two distinct bands of snow in the area; one around midnight and another during the morning commute. We picked uo about half an inch in the first round and one to three inches with the quick burst of heavier activity in the morning. It looks like another weak disturbance will bring half an inch to an inch of snow between Wednesday afternoon and evening through early Thursday. A heavier round of snow still lurks in the 7 day forecast for the weekend, especially on Sunday, but it’s too early to pin down too many details at this point. In the meantime, here’s a look at some of Tuesday morning’s snowfall totals from the National Weather Service in LaCrosse:

Another Day, Another Dusting of Snow

Our active, “Albert Clipper heavy” weather pattern continues this week as each day seems to bring a light “dusting” of snow and temperatures remain fairly typical for this time of the year. In other words, no arctic air or temps in the 40s to talk about right now. We’ve had four of these fast moving, light snow producing clipper type systems in the past five days and it looks like we’ll have have another two or so this week before the pattern changes. The next round will be tonight when an inch or so of snow is expected to fall in much of the area. Another may bring less than an inch late Wednesday and Wednesday night. Here’s a look at some of the snowfall amounts from Sunday night’s snow event. The totals listed were compiled by the National Weather Service in La Crosse, Wisconsin. The seasonal snowfall total for Rochester currently stands at 19.9 inches. We registered 24 inches in all of last winter, so we’re not far from surpassing that total already this season.

A Tale of Two Winters

Last Winter we couldn’t buy snow and cold, but this year is shaping up to be a little different.  We have our snow cover back, we got our White Christmas, and as we head through the first week of January we are going to get our bitter cold.

All of last Winter we had 20.6″ of snow fall in Rochester.  To date at the Rochester International Airport, where  all official  snowfall information is taken, we’ve seen 14.5″.  Things are definitely a bit different around here thus far when you compare it to the crazy and unusual Winter we had last year.   Here is a comparison from this winter so far to last years winter through December 29th.

We have doubled the snowfall from this point last year

Here is another perspective.  It wasn’t just warm and dry on northern Iowa and southern Minnesota, it was warm and dry everywhere.  The next two graphics tell that story.  The first is the snow cover on December 29th of 2011 and the second is the snow cover as of December 29th 2012 across North America.   The difference is EYE-POPPING.   The white on the maps below indicate where there is snow.

December 29th 200 North America Snow Cover

As mentioned things have changed big time, especially in the lower 48.  There is snow on the ground as far south as Texas, Oklahoma, and Arkansas.

North America Snow Cover as of Dec. 29th 2012

It doesn’t look like we will add to the snow pack over the next several days, but the Arctic will pay us a visit bringing MUCH colder air to Iowa and Minnesota.

The Coldest Morning of the Season So Far

We woke up to the coldest morning of the season today as strong high pressure set the stage for a clear, frosty, winter-like morning across the area.  Under the cloud-free skies and with nearly calm winds, our temperatures took a nose dive overnight into our Tuesday morning as the vast majority of the local area found itself in the teens for the first time since the first week of March.  While it certainly was a little cooler than normal for today’s date, Rochester’s morning low of 17° certainly wasn’t anywhere near the record of -4° set in 1986, but it definitely was a reminder of what late fall can bring in this climate.  If you’re not quite ready for this type of temperatures scheme, there is good news for you, however.  Slightly milder, more seasonal weather is expected for the remainder of the week and likely next week as well, so 20s and 30s will be more common than teens. 

The coldest low temps of the season so far for just about everybody today.

Some more local morning temperatures.

A Chilly, and in Some Cases, Frosty Morning

We’re really getting our first taste of true fall weather today, and not just September’s version of autumn, but more of an early October feel in the air for our Tuesday.  This is thanks to a strong area of Canadian high pressure that is moving through the Upper Mississippi Valley, drawing in unseasonably cool, dry air from up north, allowing us to see 30s on the map for the first time since April and a few patches of frost as well.  The development of frost wasn’t a surprise for us, in fact there was less than we’d thought there might be thanks to some pesky clouds that blanketed much of southeastern Minnesota and northeastern Iowa for the middle portion of the overnight period, keeping temperatures up a few degrees.

Incidentally, the averages for this time of the year are 71/49 in Rochester.

A small patch of frost on the roof of Peter Kramer in Rollingstone, MN.Morning lows for Tuesday, September 18th. The first 30s of the season!

A Warm Weekend, Then Reality Sets In

			

			
What a gorgeous finale to the work week we have going for us today!  High pressure is bringing us a cloudless and mild late summer/early fall day today as temperatures are climbing into the mid and upper 70s across the region.  Things will get a bit warmer as we get into the heart of the weekend with the help of southwest winds that will be flowing into a storm system well to the north of the Canadian border will warm things into the upper 70s and low 80s for Saturday and Sunday.  The climate average temperatures for our area are 72 for highs and 51 for lows, so yes, things will continue to be slightly warmer than normal for this time of the year, a trend we’re accustomed to in an unusually warm year overall.  However, it does appear that there will be quite a cool down in the coming week to possibly “balance things out” and bring some measure of fall weather to the picture just in time for the run up to the autumnal equinox which takes place next Saturday.  It doesn’t always work like his, but more often than not, there is some kind of  balancing act in ou weather that swings temperatures back the other way when we’ve been on an unseasonable temperature trend.  The jet stream next week is expected to push way to he south in the eastern half of the country, including our local area, allowing a series of strong cold fronts to swing through the Upper Mississippi Valley, making for a slightly cooler than normal situation for possibly a couple of weeks or more as it appears right now. 


In the meantime, we do have a little taste of comfortable late summer weather in store for this weekend and below is tonight’s Friday night football forecast.


 


It looks like we'll enjoy a gorgeous evening for football across our area tonight.The jet stream (upper level atmospheric wind current) will push southward next week, possibly keeping things cooler than normal for us by several degrees.The latest outlook for next week from the Climate Prediction Center has our region likely on the cool side for temperatures.

Rainfall Summary

			

			
While it wasn’t necessarily the biggest or heaviest rain event of the season, Wednesday and early Thursday’s rainfall was very much appreciated and extremely important.  Most spots in the viewing area registered more than a quarter of an inch and some areas almost reached a full inch, cutting just a little out of that huge five to ten inch rainfall deficit for 2012 that has been the weather headline for months.  The first measurable rainfall in a week may have at least greened up the lawns and gardens a little anyway.  Here’s a look at the local rainfall summary:


A nice, gentle, soaking rain was just what the doctor ordered. The highest amounts locally fell in northern Iowa

Rainfall Deficit

			

			
A cold front has swept through the Upper Mississippi Valley today, ushering in some cool, Canadian air and producing some light rain showers and gusty winds for us.  Unfortunately, as we’ve seen so many times this year, rainfall amounts have been sparse with this rain event locally with less than a tenth of an inch being registered in most locations.  As we look ahead to the weekend and next week, rain chances look meager with sunshine and seasonably mild weather expected instead.  We learned earlier this week that most of our viewing area has either entered the US Drought Monitor’s outlook or moved up a category in that outlook because of our current spell of appreciable rainfall. 


Extreme Drought conditions keep expanding across the Midwest with many locations now entering the Drought Monitor Outlook as "abnormally dry."


 


Moderate to Extreme Drought conditions continue to linger in much of Minnesota. Rochester and a large part of southeastern Minnesota are now in the "abnormally dry" category.


 


Drought conditions in Iowa remain dire as much of the state is still in Extreme Drought or worse.


 


Mason City's rainfall deficit is approaching a foot for the year.


 


Rochester's rainfall deficit for the year is approaching five inches.

Severe Weather and Rainfall Reports

			

			
A cold front overnight triggered quite an intense line of thunderstorms in our area that toppled trees, knocked down power lines, damaged roofs, and even started some fires.  If there is any good news in all of this, it’s the rainfall we received from those thunderstorms.  Below is a map showing doppler radar estimates of how much rain fell overnight.  This is helpful in enabling us to see specifically where the highest amounts fell and giving us an idea of how much fell between observation points.


Beneficial rain fell across the entire viewing area Tuesday night. The highest amounts were reported in northeastern Iowa where more than 5 inches were estimated on doppler radar. Southern Minnesota registered a quarter of an inch to a little more than an inch of rainfall.


 


 


 




Severe Weather of September 4-5, 2012

Local Storm Reports






Storms developed rapidly on the afternoon of Tuesday, September 4th across parts of western Wisconsin and southeast Minnesota.  They produced sporadic large hail as they continued to grow, expand in coverage area, and moved into northeast Iowa and southwest Wisconsin.  Hail over 2 inches in diameter was reported with stronger storms along with localized wind gusts ranging from 60 to 75 mph.  As storms moved into southwest Wisconsin, at least one tornado formed in northwest Grant County, Wisconsin.


Heavy rain also fell that led to flash flooding.  The terrain in the region enhances the flood threat.


In addition, a second area of thunderstorms developed over eastern South Dakota by mid evening which progressed east and prompted additional warnings for strong thunderstorm winds.

Will Isaac Affect Our Weather?

			

			
While all eyes continue to watch Tropical Storm Isaac in the Gulf of Mexico, we in the Upper Mississippi Valley are looking ahead to the end of the week when that storm may get close enough to actually impact our weather.  At this point, the National Hurricane Center’s five day cone forecast spreads the potential of rain in our direction by Friday night or Saturday morning.  With that said, the probability seems somewhat remote as it appears Isaac will first weaken to a tropical depression by Wednesday after making landfall in the Gulf coast Tuesday evening, and then begin to move eastward by the time it moves as far north as the mid Mississippi Valley around St. Louis.  The best case scenario as suggested by some computer model runs over the weekend, was for Isaac to produce some scattered thunderstorms in far southeastern Minnesota, southern Wisconsin, and through Chicago on its northern flank.  Right now that doesn’t look as likely, but it’s not completely impossible, so we will be watching, waiting, and hoping for some rainfall from this storm system.  The current rainfall deficit for north Iowa for the past year is around 10 inches and that area is in Extreme Drought while southern Minnesota is under Abnormally Dry to Moderate Drought conditions with deficits for the summer around four or five inches.


The current forecast track for Isaac. It's depicted here at a hurricane track as the storm is expected to reach hurricane status before making landfall late Tuesday.


While it currently seems unlikely that Isaac will bring much rain to our region, there is still a lot of time before the storm gets close enough to directly impact the Midwest. There is just a slight chance for some rain for our area from Isaac at this point in our weekend forecast.
