ARC Weather forecast 30/11/2015

Synopsis: Good day. A strong thermal trough extends from the Canaries NE through the Alboran Sea. This trough will weaken through tomorrow, then dissipate into the 02/12. On the 03/12/AM, a cold front will extend from S of Ireland SW to W of Madeira. This front will weaken as it moves NE over N Spain into the 04/12. An area of high pressure centered E of the Azores on the 04/12 will build a ridge S through the Canaries through the 05/12.

In the long range, an inverted trough of low pressure is forecast to extend from 20N/20W NNW to W of Madeira on the 04/12. The trough is forecast to drift W through the 05/12 to extend from 20N/23W NE to 35N/28W on the 05/12, then dissipate into the 06/12. A cold front will extend from the Azores SW through 30N/40W by the 06/12/PM and weaken as it tracks E through the 07/12.

A strong area of high pressure is currently located over the NE United States. This high will strengthen as it tracks E, reaching 35W by the 03/12, with ridging building S into the E Caribbean. This ridge will then drift slowly E while continuing to strengthen through the 05/12.

Conclusion: Winds and swells across the n grids are expected to gradually ease and abate through tomorrow as the high pressure ridging broaden and weakens, with winds becoming more S in grids DD and CC. The strongest winds and largest swells will continue to be found in grids HH and GG due to the strong interaction between the high pressure ridging and thermal trough of low pressure. Generally benign conditions are expected across the central parts of grids EE, DD, and CC by tomorrow evening as the ridge axis settles across those grids, with more enhanced trades found in grids JJ and II where the ridging is stronger.
