Mark Dee Posted March 1, 2014 Author Share Posted March 1, 2014 Note 45 kts wind max at 5,000 ft over New Orleans Thursday. More impressive, on Friday note expansive 60-65 kts winds at 5,000 ft over FL plus the Carolinas - there due to squeeze with Arctic high pressure to the north.

Mark Dee Posted March 1, 2014 Author Share Posted March 1, 2014 From NWS TallahasseeThe main concern in the extended period comes on Thursday as apotent shortwave carves through the northern Gulf, resulting inrather significant Gulf cyclogenesis. This forecast will favor the12z ECMWF as it has held a much steadier forecast over the pastcouple of days, and is also supported by the CMC. The surface low-track, as well as the low and deep layer wind profiles are quiteconcerning with respected to severe convection. Both the ECMWF andthe CMC, depict a 50+ KT LLJ nosing right up Apalachee Bay.Further, a strong mid-level jet max raises deep layer shear valuesover 60 knots. However, as impressive as that is, both the ECMWFand CMC depict enough isentropic rain ahead of the dynamic system,to effectively cut off any chance of surface based storms.Nonetheless, with considerable differences between the GFS andECMWF, the forecast remains highly uncertain and with suchimpressive wind fields, all interests should pay close attentionto forecast changes as the system draws nearer.
