July 30 Heat Ending With Rain And TS Isaias East Coast Track

Thursday July 30 2020

There is a lot to talk about this morning. The heat wave is about to end, which could make today the last day in the 90s for a little bit. A series of fronts and waves of low pressure should bring us rain tonight and Friday. Temps are expected to drop and settle in the 70s tomorrow afternoon! Amazing, right? It will come with continued off/on showers.

More showers this weekend will make it challenging to lock in your plans.

Tropical Storm Isaias has winds up tp 60 mph and has brought flooding rain to Puerto Rico. The track comes close to Miami this weekend, then curves up the east coast.  This could bring us some steady rain next Tuesday and Wednesday. See that outlook below.

Computer Model Forecasts

 

National Hurricane Center Forecast

The error in modeling, which included what we saw with Douglas in Hawaii… Makes the left or north/east side of the center track more likely. I would NOT consider this locked in yet. That is why there is a cone we will emphasize with each new outlook.
