NHC puts a label on the system in the gulf that is going to merge with the cold front.

GULF OF MEXICO...
WATER VAPOR IMAGERY INDICATES A VIGOROUS MIDDLE TO UPPER LEVEL
TROUGH MOVING ACROSS THE FAR NW GULF. THIS FEATURE SUPPORTS A
1006 MB LOW CENTERED NEAR 28N93W WITH A SURFACE TROUGH EXTENDING
SSW FROM THE LOW CENTER ALONG 25N95W TO NEAR 22N97W. DESPITE THE
LOCATION OF THE SURFACE LOW AND TROUGH...SCATTERED MODERATE TO
HEAVY SHOWERS AND THUNDERSTORMS ARE DISPLACED E OF THE SURFACE
FEATURES OVER THE COASTAL WATERS OF MISSISSIPPI AND EASTERN
LOUISIANA N OF 26N BETWEEN 87W-92W...WHERE MUCH OF THE LIFTING
DYNAMICS ASSOCIATED TO UPPER DIFFLUENCE IS LOCATED. ISOLATED
SHOWERS AND THUNDERSTORMS ARE ALSO WITHIN 100 NM E OF THE
SURFACE TROUGH. MOIST SOUTHERLY LOW-LEVEL FLOW IS ELSEWHERE
ACROSS THE ERN HALF OF THE GULF WITH A FEW LINES OF SCATTERED
SHOWERS AND POSSIBLE ISOLATED THUNDERSTORMS N OF 25N E OF 90W.


COMPUTER MODELS SUGGEST THE SURFACE LOW WILL MOVE NE OUT OF OUR
DISCUSSION AREA TONIGHT AND BECOME EMBEDDED WITHIN THE NEXT COLD
FRONT TO SWEEP FROM THE CENTRAL PLAINS INTO THE SE CONUS BY
EARLY TUESDAY
. HOWEVER...WHILE STRONG SUBSIDENCE TAKES OVER THE
W AND NW BASINS...THE WEATHER ACROSS MUCH OF THE ERN HALF OF THE
GULF AND BAY OF CAMPECHE WILL REMAIN UNSETTLED AS SURFACE
TROUGHING LINGERS IN THIS REGION OVER THE NEXT 24-48 HOURS

This system isn't an invest. On NHC page there isn't even a circle around it. Regardless, it's gonna bring a lot of rain and strong winds similar to a TS or hurricane, and it kind of has the shape of one too.

No circle because no chance of becoming a Tropical System. I was suprised to see it labeled as Invest 93 because I thought it was just a surface low or an upper low. But they feel its a Sub Tropical System
