Re: ATL: INVEST 90L
I wish they would issue a TWO to let us know their thinking. They haven't posted anything on Facebook either.

THE ATLANTIC OCEAN...
THE AFOREMENTIONED DEEP LAYER TROUGH ACROSS THE ERN CONUS IS
SUPPORTING A COLD FRONT WHICH HAS NOW MADE ITS WAY JUST OFF THE
COAST OF THE CAROLINAS CROSSING NRN FLORIDA NEAR CAPE CANAVERAL.
A PRE-FRONTAL SURFACE TROUGH IS AHEAD OF THE FRONT ALONG 29N77W
ACROSS THE NW BAHAMAS TO WRN CUBA. SCATTERED SHOWERS/POSSIBLE
THUNDERSTORMS...SOME VERY STRONG...ARE WITHIN 200 NM AHEAD OF
THE FRONT. THE REMAINDER OF THE W ATLC IS EXPERIENCING FAIR
CONDITIONS DUE TO DRY AIR ALOFT AROUND AN UPPER LEVEL RIDGE
BETWEEN 60W-73W. ACROSS THE CENTRAL ATLC...A CUTOFF UPPER LEVEL
LOW IS NEAR 28N50W SUPPORTING A 1009 MB SURFACE LOW NEAR
31N54W. A DISSIPATING STATIONARY FRONT EXTENDS FROM THE LOW
CENTER ALONG 29N46W 24N40W 21N30W. A SURFACE TROUGH IS W OF THE
FRONTAL BOUNDARY ALONG 29N49W 26N48W 21N50W. ISOLATED SHOWERS
ARE ALONG THE TROUGH AND ERN PORTIONS OF THE FRONTAL BOUNDARY.
SCATTERED SHOWERS ARE CLOSER AND E OF THE LOW CENTER FROM
28N-32N BETWEEN 43W-53W. GALE FORCE WINDS ARE NOTED E OF THE
FRONT TO 44W...N OF 29N. FARTHER E...ANOTHER CUTOFF UPPER LEVEL
LOW IS SPINNING NEAR 35N18W SUPPORTING A 1008 MB SURFACE LOW
NEAR 34N17W. SCATTERED SHOWERS ARE WITHIN 120 NM OF THE LOW
CENTER. A RECENT WINDSAT SCATTEROMETER PASS INDICATES WINDS UP
TO 30 KT ARE NW OF THE CENTER. A WEAK SURFACE TROUGH ASSOCIATED
WITH THIS SYSTEM EXTENDS INTO THE DISCUSSION AREA ACROSS THE
CANARY ISLANDS WITH ISOLATED SHOWERS ALONG IT.

People need to remember that whilst 17C is cold in terms of SSTs...its MARCH and the upper temps are very cold still at this time of year.
Remember people its all about the thermal difference between surface and the various levels of the atmosphere, as these systems in the NE Atlantic have proven over and over again!

exactly, when you buy a car, you don't just look the exterior, you also check under the hood, and this system under the hood is screaming non-tropical.

Invest:
A weather system for which a tropical cyclone forecast center (NHC, CPHC, or JTWC) is interested in collecting specialized data sets (e.g., microwave imagery) and/or running model guidance. Once a system has been designated as an invest, data collection and processing is initiated on a number of government and academic web sites, including the Naval Research Laboratory (NRL) and the University of Wisconsin Cooperative Institute for Meteorological Satellite Studies (UW-CIMSS). The designation of a system as an invest does not correspond to any particular likelihood of development of the system into a tropical cyclone; operational products such as the Tropical Weather Outlook or the JTWC/TCFA should be consulted for this purpose.

Re: ATL: INVEST 90L
For me evident warm core cyclone, convection not possible in the cold core cyclone center.
