CRNT TOR WATCH IN CNTRL SD WL LIKELY BE REPLACED WITH A NEW WW SHORTLY FOR AREAS FURTHER EWD INTO THE FSD FA.

INCREDIBLY STRONG DIR WIND SHEAR EXISTS PER THE RUC40 AND META SNDGS THIS EVENING OVER THE FAR WRN FSD FA...BUT WITH MINIMAL SPEED SHEAR. MODERATE INSTABILITY IS ALSO RELAVENT ACRS THE WEST.

THEREFORE THOUGHTS ATTM ARE NOT TO EXPECT WIDESPREAD STRONG WINDS TRANSLATING DOWN TO THE SFC...HOWEVER THIS AFOREMENTIONED STRONG DIR WIND SHEAR COULD PRODUCE THE HAILERS. GOING FCST IS IN GOOD SHAPE ATTM. NOT SURE IF I WILL BE SENDING AN UPDATE TO THE ZFP TEXT OTHER THAN TO INCLUDE THE NEW WW.

TWEAKED DOWN THE LOWS IN SW MN A COUPLE OF DEGS DUE TO CRNT TEMPS...HOWEVER TEMPS WL LIKELY BE RATHER STEADY IN THAT AREA FOR MUCH OF THE NIGHT. HARD TO UPDATE SKY COVER WITH NO SAT IMAGERY COMING IN. FLOOD WATCH WL CONT IN THE ADVISED AREA FOR THE REMAINDER OF THE NIGHT.
