TROUGH OF LOW PRESSURE NORTH OF DOMINICAN REP. REMAINS BAROCLINIC

Trough of low pressure north of Dominican Republic remains a Baroclinic system with a cold core center and exposed with no convection (thunderstorms) near the center of circulation.  Non of the models are suggesting significant development as it sits in this general area but could gather some strength as it tracks northeast to an east-northeast in the coming days.  If that were to occur it would be a short strengthening period as it races over the north Atlantic waters.  Not a threat to the U.S. mainland.  ralphstropicalweather.myfreesites.net

BAROCLINIC ZONE:
A region in which a temperature gradient exists on a constant pressure surface. Baroclinic zones are favored areas for strengthening and weakening systems; barotropic systems, on the other hand, do not exhibit significant changes in intensity. Also, wind shear is characteristic of a baroclinic zone.
