TOMORROWS THUNDERSTORM OUTLOOK

14 minutes ago
Tomorrow's Severe Thunderstorm Outlook.


TROPICAL WEATHER OUTLOOK MAY 21, 2019 0134 PM EDT

 CORRECTION MADE TO SURFACE MAP BELOW. I ADDED ADDITIONAL FRONTAL BOUNDARIES

Atlantic Tropical Waves:

1. A westward moving tropical wave near 21°West and 22° West is not showing signs of organization.  However, there is plenty of thunderstorm activity present south of 10° North from 53° West to 10° West.  These storms are not associated with the wave.

2.  I am still monitoring the East Pacific and the Southern Caribbean for development as the GFS model continues to insist that low pressure will for somewhere in the circled area and could develop either Sub-tropical or tropical.  I will keep you posted.
