AREAS AFFECTED...SERN OK...SWRN AR...FAR NERN TX

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 270228Z - 270330Z

CONVECTIVE COVERAGE WILL GRADUALLY INCREASE OVER THE NEXT FEW HOURS.
STORMS WILL MAINLY BE CAPABLE OF PRODUCING MARGINAL/SEVERE HAIL.
CONVECTIVE TRENDS ARE BEING MONITORED FOR A POSSIBLE WW.

A GRADUAL INCREASE IN CONVECTION HAS BEEN NOTED RECENTLY ACROSS SERN
OK/SWRN AR...ALTHOUGH IN GENERAL LIMITED INSTABILITY HAS PREVENTED
STORMS FROM PRODUCING MORE SIGNIFICANT SEVERE WEATHER...DESPITE
ADEQUATE SHEAR. ADDITIONAL UNCERTAINTY LIES WITH THE OVERALL
EVOLUTION OF CURRENT CONVECTION...ALTHOUGH A SLOW EVOLUTION OF A MCS
REMAINS POSSIBLE. A SUBTLE SHORT WAVE APPROACHING SWRN OK AHEAD OF
THE MAIN UPPER LOW WILL LIKELY CONTRIBUTE TO CONVECTIVE
DEVELOPMENT...WHILE PROFILER AND 00Z SOUNDING DATA INDICATES A 50-60
KT 500 MB JET NOSING INTO THE REGION. LAPSE RATES WILL SLOWLY
STEEPEN OVER THE NEXT FEW HOURS...WHILE THE APPROACHING LOW/COOLING
ALOFT WILL CONTRIBUTE TO INCREASING ELEVATED INSTABILITY AS WELL.
EXPECT INITIAL DEVELOPMENT JUST N OF THE WARM FRONT...NOW
APPROACHING THE OK BORDER...AS STRONG WARM ADVECTION AIDS IN
ELEVATED CONVECTION. HAIL WILL REMAIN THE PRIMARY THREAT AS A CAP
LIMITS SURFACE BASED DEVELOPMENT. SHOULD AN INCREASE IN CONVECTION
BE OBSERVED...A WW WILL NEED TO BE ISSUED.

Step out, come back and my county is under a tornado warning (Grayson County).

Really ominous looking to the west, big hail, vivid lightning, and very low swirling clouds as the storm moves this way.

One of those hooks is on line for the part of Denison that I live in.

Well at least today's event managed to spawn a couple tornadoes. On the topic of tomorrow and Saturday's convective outlooks (tomorrow currently has an SPC moderate risk over N MS, E AR, and W TN and Saturday's was mentioned as possibly being upgraded to MDT at the next forecast), which day's event do you think will be more impressive? I don't like the wording of the Day 3 outlook:

TSTMS ARE EXPECTED TO BE ONGOING SATURDAY MORNING FROM THE TN VALLEY
INTO CNTRL GULF STATES AHEAD OF COLD FRONT. THIS ACTIVITY WILL
QUICKLY MOVE/DEVELOP NEWD ALONG SURFACE LOW TRACK INTO THE MID/UPPER
OH VALLEY AND MORE EWD INTO THE ERN GULF STATES OVER THE COURSE OF
THE DAY. THE COMBINATION OF THE VERY STRONG WIND FIELDS AND DYNAMIC
FORCING FOR ASCENT WILL FAVOR MULTIPLE LINE SEGMENTS WITH EMBEDDED
SUPERCELLS/BOWS CAPABLE OF POTENTIALLY WIDESPREAD DAMAGING
WINDS...HAIL AND TORNADOES.

THE SEVERE WEATHER THREAT WILL CONTINUE SATURDAY NIGHT OVER PORTIONS
OF GA/N FL INTO THE CAROLINAS AND VA ALONG/AHEAD OF COLD FRONT
SURGING THROUGH THE APPALACHIANS. WIND FIELDS WILL REMAIN VERY
STRONG WITH A CONTINUED THREAT FOR SUPERCELLS/BOWS CAPABLE OF
TORNADOES AND DAMAGING WINDS.

Multiple lines of supercells and bows with the potential for tornadoes? Sounds like a possible major outbreak to me.

[Texas Snowman]

Big hail not far away, KXII met Steve LaNore talking about strong rotation developing. Looks like the main threat is Pottsboro, Denison, northern portions of Sherman best as I can tell. We've got about 10 to 15 minutes before it all breaks loose. Getting the family all squared away in our downstairs interior closet under the staircase.
