Summary of the extratropical storm.(updated)

Added more info and pictures to this write up...Should be the last update....Click on pictures to see full size.
Also noted this storm does not hold the lowest pressure reading in the CONUS as thought...This has been comfirmed by the NCDC.... The lowest pressure reading for the CONUS was set at Canton,NY back in 1913 with a pressure reading of 955.0 MBS or 28.20"... Also this as occurred in March 7.1932 at Block Island RI...... However this low still set reacords in MN and WI....

This storm has gone down in the history books as stated before…. Some interesting facts about this storm. Here at the Weather Center we were talking about this storm since October 15th ,while other forecasting sites were down playing it we remain on top of it…. We knew it had a making of a major storm close to home, and sure enough it did play out that way…. The storm did stay to West in MN this is where the lowest pressure reading did occur. Bigfork MN recorded an all time low pressure reading of 955.2 MBS or 28.21” of mercury…. Superior came in with an all time lowest pressure reading for WI.28.40” of mercury. Here at the office we recorded a pressure reading of 28.38” of mercury…. This history breaking storm not only effected  the upper Midwest it’s effects were felt throughout a large area of CONUS and Canada….
This is a preliminary data from the SPC.... 52 tornadoes were reported the 26th.... There 9 people inj... 2 from WI as a tornado tore through Kenosha County... The NWS rated this an EF1....

Winds became a big problem with this storm… Sustained winds of 30 to 40 MPH and gusts up to 65 MPH… Here at the office we recorded a wind gust of 54.8 MPH.. This caused widespread damage… Many areas had lost power, along with many downed trees and power lines. Here at the office we lost trees in the yard and without power for a fair amount of time, not only once but three times we lost power… Was also damage to buildings throughout my FA…

Lets talk about rainfall…. Here at the office we picked up a total of 2.50 inches of rain. This was common throughout the FA…. Snowfall on the other had many of my Central and Southern areas stayed warm enough for just rain, while part of my central areas did pick up around an ¼ “ of snow…. My Northern areas did see around ½” of snow Wednesday early morning.. The highest amount of snow fell in MN with 9 inches in St. Louis County….

This power house of a storm system did drag in cold air in, here at the office we never made out of the 30s today... Don't worry the cold air won't last long... Details of that tomorrow....

Now time for some pictures….

Picture below shows two areas of low pressure, first one centered over Eastern ND,Northeastern SD into parts of Western MN...The second on is Centered over Eastern NE,Western IA..Both had pressure readings of 982 MBS.

The map below shows both areas of low pressure have joined and bombed out over MN at 956 MBS.

This is the satellite imagery showing how much the of the CONUS was effected by this history breaking storm system. Snow on the backside with severe thunderstorms along the cold front in the OH and TN Valleys.

Here is the SFC map showing the low bombing out over MN..Along with the very strong winds.Closer the isobars the stronger the wind gradient..Also meaning strong winds at the SFC in the case of this map....

This map below shows the times when the two low pressure systems joined forces...Map from the La Crosse NWS......

Below pictures are from just some of the damage that happend..

Info Taken from the NWS (update info from NCDC)

This info come from the NCDC.....

Did this storm break a national low pressure record? No. Bigfork, Minnesota recorded the lowest pressure in the U.S. for this particular storm. Bigfork had a minimum sea level pressure of 955.2 millibars (28.21") at 5:13 PM CDT. This set a new record low sea level pressure for Minnesota. However, this turns out to be the second lowest sea level pressure for a non-tropical (extratropical) low pressure system in the Continental United States. The National Climatic Data Center determined that the lowest CONUS, land-based, non-tropical, sea level pressure that can be confirmed is 955.0mb (28.20"). This occurred twice in United States history. The first time was on January 3, 1913 at Canton, NY. The second was on March 7, 1932 at Block Island, Rhode Island. These were verified by the NCDC using archived climate data publications. Many storms have been discussed as potential record holders for the lowest recorded sea level pressure in a non-tropical storm at a land-based observing station in the Continental United States (CONUS). The lowest that has been mentioned was 951.6 millibars at Bridgehampton, NY on March 3, 1914. However, this value cannot be confirmed by records held at the National Climatic Data Center (NCDC).





Older post...This info form the NWS...
New Record Low Pressure for a Non-Tropical Storm in the Continental U.S.


A new record was set on October 26th for the lowest pressure in a non-tropical storm in the mainland U.S.



The massive storm system barreling across the central U.S. had a minimum central pressure of 28.24" or 956 mb (equivalent to the minimum pressure of a Category 3 hurricane).



This breaks the old record of 28.28" (958 mb), set on Jan. 26, 1978, during the Blizzard of 1978 (aka the Cleveland Sueprbomb). This is also lower than the March 1993 Superstorm (aka "The Storm of the Century"), or the "Witch of November" storm that sank the Edmund Fitzgerald in 1975, or even the Columbus Day Storm of Oct. 1962.

First snowfall of the session

Just two pictures of the first snowfall of the session...Here at the Weather Center we picked up 1/2 of snow overnight.The snow did melt down to aroudn 1/4"...Should see another 1 to 2 inches of snow throughout the day....

RECORD BREAKING STORM SYSTEM...

This storm system is going down in the record books for the lowest pressure readings throughout Western/Northern WI….. Superior came in with a 28.38 inches or 961.06 MBS,Here at the office we had recorded a pressure reading of 28.40” this is the lowest I have ever seen a pressure reading in all my years of watching/forecasting the weather…. Winds another side of this storm…. Did have some wind damage here at the office and throughout Barron County….Winds gust here at the office so far as been 50.9 MPH…. This still could go higher… Winds of right now 30 MPH…. Gusts 40 to 45 MPH….. A record breaking storm for sure…. This one will be talked about for some time to come…..Not only that it was fun to forecast as this was the first place you heard about it....


Rain as began to mix with snow that trend should hold through the rest of this late afternoon and evening…Still thinking rain will change to all snow…. See the forecast below for where the snow line should setup…..

Snow

Rain is now mixing with snow....Still winds well over 30 MPH with gust up to 50 MPH...Had a few tress downed in my yard along with some large branches.... More later to busy with damage stuff tight now...

Short term forecast number 2

At 12:00 AM this Tuesday  morning radar showing a rather large area of showers and thunderstorms throughout the FA,this trend will hold through the over night hrs...Winds have picked up out of the East/Southeast from 12 to 20 MPH with gust up to 33 MPH through through out the Central and Southern areas...Here at the office winds E/SE 20 MPH with gusts up to 30 MPH...Mod rain falling at the office as well....Look for winds to keep increasing throughout the over night hrs...Winds of 30 to 40 MPH with gust 50 to 60 MPH with even higher gusts possible..This storm system could very well produce widespread wind damage from later tonight through Wednesday evening...Winds should die down for time tomorrow before picking back up...Rainfall amounts from 1 to 2 inches will also be possible with this system....Snowfall amounts should be light however will have to watch how fast the cold air makes into the area along with how much moisture will be in place...Will have updates on snowfall amount tomorrow if need....Still the best area to see accumulating snows though light as of right now, would be North of a line from Luck in Polk County to  Canton in Barron County over to Ladysmith in Rusk County...Stay tuned to the Weather Center for updates and latest forecasts on this power house of a storm.

Short term Forecast 1

Showers and thunderstorms are moving into the area...This should last through out much of the night...Pressure reading is down to 28.97 "...Winds will begin to increase as a strong low pressure moves into the area...Winds will ramp up to the 30 to 40 MPH range with gusts reaching 50 to 60 MPH with even higher gusts possible....This could lead to widespread wind damage through out the area for Tuesday and into Wednesday night....Snow still looks likely see forcast below for that info....It appears it will be some light accumulations... Still the track is not set in stone...
