Yesterday's severe weather write up...

First off here are the temps form the Rice Lake Airport...I really hate using this..However my station recorded 85.9...That is a bogus reading....See this link for that.... http://www.weather.gov/data/obhistory/KRPD.html



Ok so why did the severe thunderstorms happen a little more North than we forecasted...We remind you it really was not that it was not than more North...Just one County North of where we had forecasted...Also we will talk about why the severe thunderstorm happen more to the East than we though they would....We did kind of bust on that side..Though Dirk did say he "he was not to thrilled about severe storms In North central WI" so this does lead me to believe he did have it covered,just he didn't want to really commit to that area.....
So here was the deal....The cold front was moving in as forecasted timing was darn near right on the money...Late morning we had strong warming take place not only is the boundary level area,but also in the upper layers of the atmosphere...Not only did this throw a strong cap (like we though,just not as strong as it turned out to be)...This slowed the cold front down to crawl...There was also a prefrontal boundary that came through the Western Counties of the FA...This push into Central Barron County and for the part stalled..ACs started to form from line form Southeastern MN right through North Central WI satellite imagery show this rather well..The cap broke over SE MN this allowed for thunderstorms to fire up near Wabuasha MN...These storm tracked to the Northeast,while more storms fires up along the SW part of said ACs line..See satellite grabs in the post above,as this is only for text.....By time storms started to fire up the cold front caught up to the prefrontal boundary..Cold front got hung up from Rice Lake South into SE MN...Storms firing along the cold front and kept moving Northeast..Same time other storms kept firing along the Western Barron County onto Western Dunn and Eastern St.Croix Counties....Storms were able go severe over Southeastern Dunn County,and Chippewa County and point South.....Cold front slowing pushed into Rusk County allowing for thunderstorms to move to the Northeast..Severe storms either moved or fired up into North Central WI....Turned out that push of very warm and dry air in the upper levels showed everything down this gave time for the cap to weaken along the prefrontal boundary...So the short reason to why severe thunderstorms blew up A county North than we forecasted and to our East...Main reports were hail however there was some wind damage reports later in the night....

Dirk does have pictures of his chase day...He will be posting them later, this way everyone has a chance to read this..He got back home just in time to catch some hail here,He said some of the hail was quarter size,most were nickel size up..He said the ground did get white from the hail...Also he will post pictures of that...He will have most of the pictures posted to his web site on Monday..
