Moe post tomorrow - time for bed.

-Steve Douglass

There will be tornadoes today ...


.CNTRL/SRN HI PLNS THROUGH EARLY WED...
INCREASING FORCING FOR ASCENT...STRENGTHENING/DIFFLUENT UPR FLOW
...LOW LVL MOISTURE RETURN...AND SFC CYCLOGENESIS WILL SUPPORT A
SUBSTANTIAL SVR POTENTIAL OVER THE CNTRL/SRN HI PLNS TODAY/TONIGHT.
STG/SVR TSTMS SHOULD FORM MORE OR LESS SIMULTANEOUSLY IN
CONFLUENT...MODERATELY UPSLOPE FLOW OVER ERN CO/NE NM...AND ALONG
N-S DRYLINE NEAR THE NM-TX BORDER.

STEEPENING LOW TO MID LVL LAPSE RATES...MODERATE INSTABILITY AND STG
VERTICAL SHEAR/VEERING WIND PROFILES WILL BE FAVORABLE FOR
SUPERCELLS...WITH LARGE HAIL AND SOME TORNADOES. THIS THREAT SHOULD
BE GREATEST LATE THIS AFTN/EARLY TONIGHT OVER SE CO/FAR ERN NM AND
MUCH OF W TX. WITH MODERATE SLY LLJ LIKELY TO INCREASE IN RESPONSE
TO CONTINUED EWD PROGRESSION OF GRT BASIN UPR TROUGH...THE
RELATIVELY GREATEST TORNADO THREAT A BIT LATER THIS EVE MAY EXIST
OVER PARTS OF THE TX PANHANDLE AND ADJACENT TX S PLNS...NEAR SFC
WARM FRONT/CONVECTIVE OUTFLOW/DRY LINE INTERSECTION.

OTHERWISE...THE INCREASING LLJ SHOULD SUPPORT UPSCALE DEVELOPMENT
INTO ONE OR MORE SE-MOVING MCSS TONIGHT. WITH EMBEDDED SUPERCELLS
AND SUSTAINED STORMS/BOWING SEGMENTS...THESE LIKELY WILL YIELD A
CONTINUED THREAT FOR SVR HAIL...DMGG WIND...AND PERHAPS AN ISOLD
TORNADO INTO PARTS OF NW TX AND POSSIBLY WRN OK
