MODELS ARE IN PRETTY GOOD AGREEMENT ON MAIN FEATURES...BUT DIFFER SOME ON TIMING OF VARIOUS WAVES TO COME ACROSS THE REGION THRU WED. HAVE GENERALLY FOLLOWED CLOSE TO ETA IN THE SHORT TERM.

SEVERE WX RISK WILL BE LESS WIDESPREAD THAN YESTERDAY...BUT THERE ARE TWO AREAS TO BE CONCERNED ABOUT RIGHT NOW. ACROSS THE WESTERN CWA...SOME CONVECTION IS FIRING OFF THE BIG HORNS AND MOVING NORTHEAST INTO PARTS OF NORTHEAST WY.

FURTHER EAST INTO SOUTH CENTRAL SD...MOIST AND VERY UNSTABLE AIR IS IN PLACE ACROSS THE AREA WITH CAPES OF 2000 TO 3000 J/KG. HOWEVER... WEAK CAP AND LACK OF DYNAMICS IS KEEPING STORMS FROM DEVELOPING RIGHT NOW. MAIN THREATS THERE...IF STORMS DEVELOP...WILL BE LARGE HAIL...STORNG WINDS AND THE POSSIBILITY OF A TORNADO OR TWO IF BOUNDARY REMAINS IN THE VICINITY. ANY THUNDERSTORM ACTIVITY SHOULD WEAKEN BY LATE EVENING...BUT STILL EXPECT ISOLATED TO SCATTERED SHOWERS ACROSS THE CWA THROUGH MUCH OF THE NIGHT. WILL SEE SOMEWHAT OF A REPEAT TOMORROW AS FIRST UPPER LEVEL LOW MOVES AWAY AND NEXT LOW TAKES SHAPE OVER PACIFIC NW. THIS WILL CONTINUE TO SEND PIECES OF UPPER LEVEL ENERGY INTO THE REGION.

HIGHS MAY STRUGGLE TO REACH INTO THE 60S ON WED WHEN THE LOW IS PROGGED TO MOVE OVER THE REGION. RIDGING BUILDS IN TOWARD THE WEEKEND WITH PROGRESSIVELY WARMER TEMPS AND MAINLY DRY WX. .UNR...NONE.
