Invest 95L is still encountering wind shear and Sahara dust and dry air. The convection (thunderstorms) associated with this system is minimal at this time. This system will be affecting the Windward Islands tomorrow evening.
As for the other system behind 95L it is also experiencing some wind shear and Sahara dust and dry air. So far this system looks to be an Atlantic system with no landfall.

12z MODEL RUN FOR INVEST 95L JULY 17, 2017 0951 AM EDT
Invest 95L still has a nice circulation but this morning it seems to be encountering some wind shear and dry Sahara dust and air. It is noticeable on enhanced IR, water vapor and visible satellite. You can see feathering of the clouds the cold cloud tops warming and thunderstorm activity has diminished some. This system now has a Medium chance 50% within 48hrs. and a Med chance 50% within 5-days.
There is another system that I circled yesterday that NHC is now also monitoring that has a Low chance 20% within 48 hrs. and a Low chance 30% within 5-days. This system is right behind Inest 95L.

TROPICAL WEATHER OUTLOOK JULY 16, 2017 0900 PM EDT
There are four tropical waves and so far the only one I am monitoring closely other than INVEST 95L. Is a new wave near between 30°-40° West. Models are suggesting development. If it does develop it will more than likely be a threat to the shipping lanes and not land. I will keep you posted.
Elsewhere tropical cyclone formation is not expected for a day or two.

TROPICAL WEATHER OUTLOOK JULY 15, 2017 0255 PM EDT
1. Three tropical waves and no signs of organization at this time.
2. There is one area of showers and storms near 40°West that models suggest some development as it tracks west towards the Lesser Antilles, so I will keep an eye on that one.
3. Some convective activity (thunderstorms) in associated with a trough in the Bahamas that is tracking west toward Florida. That will more than likely enhance showers and storms plus lightning tomorrow maybe on Monday.
4. We also have the persistent trough in the Gulf that also has is producing thunderstorms with plenty of lightning along the Florida Big Bend westward over the northern Gulf waters. This trough is also tracking slowly westward.

The tropics remain quiet for now. There are three waves and the one near Dominican Republic could enhance rain and storm chances for the Bahamas and Florida in the coming days. Lightning detection network shows lightning over the southeast Bahamas and a portion of Dominican Republic and Haiti
