The following synopsis will be a “quickcast” this evening.
The NHC has taken an interest in the area of “disturbed” weather in the GOMEX. The NHC has designated a 20% probability for development over the next 7 days.
NHC 7 DAY GTWO
Satellite imagery indicates a rather disorganized area this evening. This area of disturbed weather is associated mainly with a trof of low pressure, and mainly a mid level feature based on the current vorticity map from CIMSS. Analysis of the latest ASCAT imagery did not indcate a surface circulation.
WEATHERNERDS SATELLITE LOOP IMAGERY
CIMSS 500 MB VORTICITY
While water vapor imagery did not indicate entrainment of very dry air, moisture was limited.
The area is currently under 25 – 30 knots of shear, and the forecast calls for wind shear to remain high over the projected path of this system. The ECMWF MSLP anomalies forecast tends to indicate this remains a large trof of lower pressure over the next few days, and the area should eventually move toward the ENE, eventually (supposedly) becoming an area of weak low pressure after crossing the Florida Peninsula. Analysis of the 200 mb streamline map indicates upper level winds are forecast to remain zonal. Based on this analysis, I do not believe this will develop into anything tropical. Although the phase evolution diagram indicates this may transition to shallow warm core near its end, I have doubts about that at the moment.
ECMWF WIND SHEAR FORECAST AND MSLP ANOMALIES FORECAST
I will continue to monitor this situation over the next 72 – 96 hours for any significant changes, and will update if necessary. Elsewhere, Tropical Storm formation is not expected during the next 7 days.
