SPC Mesoscale Discussion
From the SPC:
SEVERE THUNDERSTORM WATCH ISSUED FOR MOST OF SOUTHERN MISSOURI FOR THIS AFTERNOON AND EVENING
“A PRE-FRONTAL LOWER/MID TROPOSPHERIC THERMAL RIDGE IS GRADUALLY BECOMING SUPPRESSED SOUTHWARD ACROSS PARTS OF THE MID MISSISSIPPI/ LOWER OHIO VALLEY REGION…TO THE SOUTH OF THE COLD UPPER TROUGH ACROSS CENTRAL CANADA AND THE UPPER GREAT LAKES REGION. AS THIS
OCCURS…DESTABILIZATION AND FORCING ALONG THIS FEATURE APPEARS LIKELY TO BECOME THE FOCUS FOR INCREASING/INTENSIFYING CONVECTIVE DEVELOPMENT FROM SOUTHERN MISSOURI INTO THE KENTUCKY/TENNESSEE BORDER AREA…WHERE MERGING/CONSOLIDATING STORMS WILL CONTRIBUTE TO ONE EXPANDING STORM CLUSTER IN THE PRESENCE OF MODERATE TO STRONG POTENTIAL INSTABILITY. FORCING ASSOCIATED WITH WESTERN PORTION OF LOW AMPLITUDE TROUGH SHIFTING WITHIN BROADER SCALE CYCLONIC FLOW
ACROSS THE REGION MAY SUPPORT ANOTHER GROWING STORM CLUSTER ACROSS SOUTHEAST MISSOURI INTO WESTERN KENTUCKY. AS THIS OCCURS…AND ASSOCIATED SURFACE COLD POOLS DEVELOP/STRENGTHEN MOMENTUM/SHEAR ASSOCIATED WITH A 30-50 KT WESTERLY 500 MB SPEED MAXIMUM WILL PROBABLY EVENTUALLY CONTRIBUTE TO INCREASING DAMAGING WIND POTENTIAL
BY EARLY EVENING. UNTIL THIS OCCURS…THE RISK FOR FREQUENT CLOUD TO GROUND LIGHTNING AND LARGE HAIL WILL EXIST…ALONG WITH A GRADUAL INCREASE IN POTENTIAL FOR HEAVY RAINFALL AS STORMS BEGIN TO TRAIN.”

6-10 Day Temperature Forecast
The jet stream pattern which has provided us with cooler air and frequent rain shots looks as if it will back off a bit by next week. This week was spent watching this pattern, which had been focusing on the northeast and Great Lake states, gradually deepen and shift westward.
This resulted in a continuous run of cool weather and frequent visits by fronts providing rain and storm chances. The pattern will still be very much in effect through thr weekend with yet another front riding through the area late Saturday.
Now next week, an area of hot weather to our southwest will expand eastward into the plains and begin to heat us up. Nineties will likely return, possibily as early as Tuesday, and might last the week.
The rain pattern will establish itself to our north and east once again as the possibility of ”backdoor cool fronts” (those that back in from the east) returns to the region.

I’ve been working to load up my YouTube page with storm chase videos. Some of the footage from this year is in HD. You’ll see stuff from 2004, the MSU chase class back in June and much more.
The videos are sorted by the drop-down menu above or you can just go to WeathermanTed on YouTube. Keep checking in for more!
