Good evening everyone!
PTC (Potential Tropical Cyclone ) FIFTEEN has been upgraded to Tropical Storm LISA by the NHC. As of the 8:00 p.m. EDT intermediate advisory, the following was available on LISA:
8:00 PM EDT Mon Oct 31
Moving:W at 14 mph
Min pressure:1002 mb / 29.59 in
Max sustained:45 mph
Satellite loop imagery indicates LISA is becoming better organized, with the heavy convection just SE of the center. Mid level dry air is just to the west of Lisa at the moment.
WEATHERNERDS IR, VISIBLE AND WATER VAPOR LOOP IMAGERY
Analysis this evening of the wind shear and upper level winds from CIMSS indicates wind shear has reduced, with a radial shear pattern now over LISA. The upper level wind pattern continues to slowly improve, and though not optimal at this time, based on the motion of upper level clouds, upper level outflow seems to be gradually becoming established. Analysis of both the ECMWF and GFS global models indicates the wind shear pattern becomes more favorable by tomorrow (12Z Tues.), along with an improving 200 mb streamline pattern, indicating outflow aloft. While the outflow channel will not e exactly centered over the storm, LISA will be entering the right, rear entrance region of a 200 mb jetstreak, which will aid in evacuation of air in the upper. The models also indicate an improving moisture pattern at 500 mb, which continues to improve up until landfall. Based on this, and OHC values of 100 – 125 j/kg, LISA should continue to gradually strengthen. Based on these forecast factors, along with the most recent SHIPS wind shear forecast, wind shear is forecast to be below 10 kts for the next 24 hours, and below 15 kts up to landfall. Given this, I cannot rule out Lisa attaining CAT 1 hurricane status just right before landfall, albeit the current SHIPS diagnostics does not indicate this. For now, I have to agree wit the NHC intensity forecast, based on the analyzed forecast parameters. I intend to look at this again tomorrow evening to try and get a better handle on intensity at landfall. The following graphics are from the ECMWF in regards to the forecast conditions mentioned.

96H 04/1800Z 17.5N 93.0W 25 KT 30 MPH…POST-TROP/REMNT LOW
LISA is currently moving toward the west. Based on my analysis of current and forecast steering layers maps, Lisa should pretty much continue on this track up until landfall. Based on the current steering layer map from CIMSS, along with forecast steering maps, I expect LISA to make a slight bend northward during the next 36 hours, however remaining on an overall westward motion until landfall. 18Z track guidance is tightly clustered, and indicate this motion which I just mentioned.

I will continue to monitor LISA for ANY significant changes, and will try to update tomorrow evening.
