Storm Reports from Wednesday’s Severe Weather Event

It was a combination of a strong surface low pressure system in northern Iowa and an upper level system that came from our northwest Wednesday that created a severe weather outbreak mainly along the Minnesota-Iowa border and across a big portion of northern Iowa. A Tornado Watch was issued for northern Iowa in the afternoon Wednesday the 12th and within a couple of hours there were a couple of confirmed touchdowns. One struck the small town of Belmond in Wright County and another minutes later touched down near Hampton in Franklin County and today the National Weather Service is sending out a survey team to assess the damage and determine the exact damage path as they try to determine just how strong those tornadoes were. They’ll later assign an EF (Enhanced Fujita Scale) rating for the tornadoes. Below is a listing of some of the damage reports from around the area:

A Chance of Strong Storms Tuesday Night-Wednesday Morning

A storm system to our west is expected to produce some showers and thunderstorms in our area later tonight through much of our Wednesday, some of which may become severe and produce some unwanted heavy rainfall. Right now, it looks like a complex of strong thunderstorms is going to develop in eastern Wyoming and western South Dakota in the late afternoon and evening hours today and then begin to quickly move eastward into a favorable environment for damaging winds as it approaches our viewing area after midnight tonight. Wind gusts may exceed 70 miles per hour, uprooting trees or knocking down powerlines in the overnight period and rainfall amounts may reach an inch or two in a short amount of time leading to flash flooding possibilities very early Wednesday morning. The Storm Prediction Center has placed out entire area in the “Slight Risk” of severe weather while a “Moderate Risk” lies just to our west in South Dakota and northern Nebraska.

Damaging winds, some hail, and locally heavy rainfall will be possible late Tuesday night and early Wednesday in our area.

Flood Warnings Continue As Does the Severe Weather Threat

The large storm system that has been keeping things unsettled and stormy for us and really the entire Midwest continues to edge its way eastward toward us, keeping things breezy, humid, and a little damp today. In the wake of Sunday night’s severe storms that produced heavy rain and strong winds, there are still a number of Flood Warnings in effect for today and even some that won’t expire for a couple of additional days while severe weather remains a concern for us in the short term. Look for occasional sunshine today that may work to destabilize the atmosphere, settting the stage for some strong thunderstorms in the late afternoon and evening. Right now the biggest concern appears to be damaging wind gusts that may topple or completely uproot trees. We’ll also have to keep an eye on rainfall amounts as soils are very soggy and can’t hold much more if any additional moisture. The rainfall from today’s showers doesn’t appear to be as heavy as Sunday’s but even a small dose now would make things worse, so the National Weather Service has issued a Flood Watch for the eastern part of our viewing area. There is also a marginal tornado threat and of course a chance for some hail in some of the stronger storms.

A look at some of the highest rainfall amounts across the area. Rochester received 2.07″ officially Sunday, a record for the date.

The latest Storm Prediction Center outlook places the eastern half of our area in the slight risk category for severe storms today and tonight.

Winter Storm Update: Wednesday Evening

Bullet Points:
-Start time: 9pm around Mason City, 11pm-Midnight around Rochester
-Will school be cancelled or delayed? If it snows as much as expected, chances are there will be many delays and cancellations, but that decision won’t be made until early Friday morning and it is made by school superintendents.
-Finish time: Snow will be wrapping up late Friday afternoon into the early evening. Travel will be just fine almost all of Thursday and will improve quickly Saturday

Here is where the storm is located at 10pm Wednesday evening, the center of the coming storm depicted by the red ‘L’.

Below are the National Weather Service headlines for Thursday evening through Friday afternoon

Below are the primary impacts from the coming snow

…and this is my snowfall forecast, between Midnight Thursday night until 6pm Friday.

Winter Storm Update: T-minus 30 Hours

The season’s strongest winter storm (at least for the Midwest) will start to affect the region late Wednesday through Thursday morning before moving east of us Thursday night. Heavy snow and strong winds will make for very difficult if not impossible travel for some, especially portions of northeast Iowa into southwest Wisconsin through much of Thursday. Not all will be affected equally though, as always, so here’s what I have for you so far. A Winter Storm Watch has been issued where snowfall totals are uncertain but where there is the potential for 6″ or more snow or at least a combination of very strong winds (blowing, drifting, lowered visibility, poor road conditions) with maybe a little less snow. A Winter Storm Warning has been issued where there is a higher probability of heavy snow combined with very strong winds and potential blizzard conditions. These headlines will absolutely change over the next 12-18 hours as the storm comes closer and there is more agreement as to strength and track of the coming storm system. The Watch will be changed to either a Winter Storm Warning, a Winter Weather Advisory, or a Blizzard Warning (if necessary) depending on the coming storm’s track. Additional counties not under a headline at this time may very well see a headline at some point. Below are the current headlines as of 8pm Tuesday evening (12/18/2012).

Below is my best take on expected snowfall totals at this time. This is also subject to and will most certainly change in the next 12-24 hours as we get a better handle on the storm system. These totals are by no means a “promise” or firm expectation of what is going to fall…we must embrace the uncertainty. Additionally, just because a county is not under a headline from the National Weather Service does not mean there will be no snow in said county. Wow…pardon the double-triple negative.

And I know, I know there are many who are of the mindset that we TV folks are out to lunch and are just a bunch of REALLY pretty faces (they mainly say that about Jonathan Kegges, the handsome devil), so below are a couple of snowfall graphics put out by the National Weather Service out of La Crosse, which covers southeast MN, northeast IA, and southwest WI.

…and from the NWS Des Moines office

There will be major travel impacts from this coming storm, but the severity will change over relatively small distances. Counties that are not covered by a headline and which receive lesser amounts of snow will still have issues with poor travel conditions even with snowfall amounts of 1-4″ combined with 20-30mph winds Thursday morning. Additionally, there will be a very sharp cutoff in the snow line from locations that receive 4″ to those that receive less than an inch. That distance of cutoff may be as narrow as one county length. Snow will cutoff sharply from the southeast to the northwest. More to come…

November 11th – 1940 vs. 2012

That was a pretty wild ride this past weekend. Rochester’s high temperature on Saturday the 10th was 75 degrees, which crushed the old record of 68, set back in 1949. In the books for Sunday the 11th is a high of 66 degrees which, remarkably, ties the record high set last in 1912. Sunday’s high temperature happened at Midnight and the low temperature was recorded just before Midnight Monday as the temperature at the Rochester Airport went down with every hourly reading. That’s an impressive drop in temperature.

This big change from summer to winter in just a matter of hours may have conjured up memories or questions regarding another old, November storm. The Armistice Day Blizzard of 1940 brought a similar, but much more intense change to wintry conditions. Comparing the two side-by-side, the cold front of 11/11/12 is hardly comparable to the crippling strength of the 1940 storm. While our temperature dropped from 66 degrees at Midnight Sunday to 23 degrees at 11:59pm Sunday, the temperature on 11/11/40 dropped from the 50s in the early morning to the teens by the mid afternoon. In addition to the drop in temperature came heavy rain, sleet and snow. The Armistice Day storm of 1940 claimed a total of 154 lives, more than 20 were duck hunters in the Winona area who were caught off guard by the dramatic shift in the weather.

Potentially Stormy Saturday

October 8th and 9th was the first measurable rain we have seen across the area since back on September 17th. Here are some of the totals from the past 48 hours.

Rainfall over the past 48 hours

There appears to be more where that came from, and maybe much more. With a potentially soaking rain (which we have desperately been waiting for and need) may also come the threat for severe weather during the day on Saturday. Right now the system that will eventually affect the Upper Midwest is spinning off of the coast of California. The red “L” just below Sacramento marks the current position of the storm. The other two “L’s” mark the track of where the Upper Level Low is currently forecast to go. We are looking at it on the water vapor imagery. This type of satellite imagery shows the amount of moisture in the mid to upper levels of the atmosphere. It is easy to see how the atmosphere is moving if there was a loop of the image below.

Current positioning and timeline of Upper Level Low

The Upper Level Low seen above on the water vapor imagery will act as the fuel for a surface low that will eventually develop east of the Rocky Mountains. Once the low emerges from the Rockies, it is forecast to deepen (strengthen) and push up into the Upper Midwest. A warm front will deliver slightly warmer air to area on Saturday. The warm sector will be the focal point for any potential severe weather to develop. The warm sector is the area below the warm front (Red Half Circles) and to the east(right) of the cold front. (Blue Triangles) As far as timing goes, it looks like we will watch clouds increase Friday night and may even start to get in on some showers that night as well. That is associated with some energy out ahead of the warm front that looks to cross the area on Saturday morning. Below is how things may look on Saturday from a surface weather map perspective.

Forecast surface map for Saturday

The Storm Prediction Center has outlined the area in a Severe Risk for thunderstorms during the day on Saturday. What that basically means is that at this time with all of the weather data we have, if things hold together as they look now we will run the potential for severe thunderstorms to develop.

Map showing the area that could see severe thunderstorms on Saturday. (As of 10/10)

As many of you know, things can change in an instant with the weather. The main body of this system is after all still offshore of the west coast of the United States and a lot can certainly change. It does appear though at this point a soaking rain is likely with some places possibly picking up near an inch of rain or more, and severe thunderstorms may accompany this rain on Saturday. We are keeping an eye on this storm. Keep checking back for updates and changes as this storm system gets closer to the Upper Midwest.

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.

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.
