WRF Model detecting Surface Low Pressure in Western Atlantic

[weatherman21]

Latest WRF Model run from 12Z this morning (8/18) is forecasting an area of low pressure which the model shows tracking into the western Atlantic by next Wednesday. Whether this holds true or not is unknown. After observing latest satellite imagery, I fail to see anything that has the potential to develop into any such tropical low pressure at this time. The only feature to speak of in the central Atlantic is an upper-level low tracking westward. Will be interesting to see what unfolds.
Below are a few images of the WRF Model run from 12Z this morning showing the possible low pressure area tracking into the model field. You will also notice Hurricane Dean on the southern portion of the first image which the WRF predicts will hit the Yucatan Peninsula. The products in the images are Precipitable Water and MSL Pressure. I set the windflow in the images to 700MB.

The WRF model continues to predict an area of low pressure to gradually track into the southwest Atlantic and this is supported by the latest guidance of the LBAR/BAMM/BAMD/BAMS models. The SHIP model calls for this system to become a 76 knot hurricane by this Saturday; however, my confidence in these models are at a low degree until something actually begins to develop. I will say that today, as opposed to a few days ago, I am noticing a tropical wave, which the NHC has been discussing, now present in the central Atlantic. This wave is obviously the one that the WRF model has been detecting over the past few days. Currently, the wave is disorganized, but that could change as the NHC is calling for the possibility of some development of this wave over the next couple days.
Notice in second image of the WRF model guidance below that the model calls for yet another possible cyclone to track northwestward across the northeastern portions of the Yucatan Peninsula and headed for the Gulf of Mexico by Saturday.
In the model images below, I have displayed 700MB winds over MSL Pressure.
